Best ultra-light mouse 2021: 21 lightweight gaming mice for FPS gaming

All of the top options tried and tested by Digital Foundry.

There's a new type of gaming mouse on the market: the ultra-light. These lightweight mice use honeycomb designs and other measures to cut mass wherever possible, making for a more manoeuvrable mouse that's easier to aim. Following the first releases by specialists like Glorious and Finalmouse, many bigger brands have now made ultra-light mice of their own with new sizes, shapes and features. Some of these mice even forgo the holey look, with internal modifications to bring weight down and an intact outer shell. After extensive testing of every ultra-light mouse in FPS games like Valorant and CSGO, we're ready to make our recommendations. Here are the twelve best ultra-light gaming mice in 2021.

Note: for the purposes of this article, we consider an ultra-light mouse as any mouse that weighs 80 grams or below - although the lightest mice often weigh considerably less. Both honeycomb and traditional body gaming mice are eligible for inclusion. For comparison's sake, most standard mice weigh at least 100 grams; the popular Logitech G502 weighs over 120 grams.

For more on ultra-light gaming mice, check out our article on why ultra-light honeycomb mice are the next big thing in PC gaming gear. We also have some frequently asked questions at the end of the article and a table of the most important specs. And if ultra-light isn't for you yet, check out our full list of contenders for the title of best gaming mouse 2021.

Without further ado, here are the best ultra-light gaming mice for 2021:

1. Glorious Model O

modelo

67 grams • PMW 3360 sensor • ambidextrous honeycomb design • 128x66x37mm • RGB

The Glorious Model O remains our pick for the best gaming mouse on the market, thanks to a clever design that combines a range of modern trends: a weight-saving honeycomb design, an extremely flexible "shoelace" cable, a modern PMW 3360 optical sensor and RGB lighting. It also ranks highly as it's an extremely affordable ultra-light, costing around £45 in the UK and $50 in the US. That's for the matte coating in black or white; a glossy coat is available for a small premium. The Model O is an excellent ultra-light for gamers with medium to large hands. The Model O is also available in a smaller size as the Model O-, a great choice for smaller hands or those looking for even lower weights (58g for the Minus versus 67g for the vanilla Model O).

2. Cooler Master MM710

mm710

52 grams • PMW 3389 sensor • ambidextrous honeycomb design • 116x64x38mm • no RGB

The MM710 is another strong option, with a unique stubby design and the lightest weight on a widely available mouse - the Finalmouse Ultralight 2 is lighter, but was only on sale for a limited time. The tall hump at the rear of the MM710 makes it a clever choice for claw grip players, fitting naturally into the bottom of the palm to provide extra comfort and control that isn't possible with a flatter mouse. The MM710 doesn't include RGB lighting of any kind, a rare choice in 2021 that does allow for small savings in weight and cost. The short but wide dimensions make this a great selection for gamers with almost any hand size.

The MM711 is a slightly heavier and more expensive version of the MM710 that adds RGB lighting and is available in multiple colours and coatings. We found it offered the same excellent performance as the MM710, with the extra 10 grams bringing it closer in weight to other ultra-light options. If RGB lighting is essential, the MM711 is a premium mouse worth considering.

3. Razer Viper Ultimate

cp2077_viper

74 grams • Razer Focus+ sensor • traditional ambidextrous design • 127x66x38mm • RGB

The Razer Viper Ultimate is a surprisingly light wireless mouse, given its long 70 hour battery life and non-ventilated design with RGB lighting. The mouse uses optical mouse switches, previously used in Razer's opto-mechanical keyboards, removing the need for a de-bounce delay and therefore speeding up clicks by a few milliseconds. The Focus+ sensor is also intriguing, promising improved responsiveness through syncing the sensor's reporting to the computer's polling rate. Behind all of this technobabble though, there's a very performant gaming mouse with a comfortable shape and top sensor, coming in at price only exceeded by that of the new Logitech G Pro X Superlight. There's also a gorgeous Cyberpunk 2077 edition (pictured above), that swaps out the regular model's black and green styling for a lovely yellow - at a £10 premium, I'd say it's well worth it if you like your mice to really stand out!

There is also a wired version, the standard Viper, which costs significantly less and weighs in at an even lighter 69g. This wired model is also available as the Viper 8K, which reduces response time by whacking the USB polling rate from 1000Hz to 8000Hz.

4. Logitech G Pro X Superlight

superlight

63 grams • Hero 25K sensor • traditional ambidextrous design • 125x64x40mm • no RGB

Logitech kicked off the trend for wireless ultra-light mice with the release of the 80 gram G Pro Wireless, combining an efficient optical sensor with a small, safe shape and a fast-as-wired connection. The G Pro X Superlight Wireless is a further evolution of the same concept, with the same core components but a kerb weight of only 63 grams. To achieve that, Logitech has cut out features like movable side buttons and RGB lighting, leaving only the bare essentials - including the solid, well-constructed feel of the original mouse. The design is a triumph, no doubt, with the only fly in the ointment being the $150/£150 asking price. There are certainly better value wireless mice on the market, including the original G Pro Wireless, but in terms of out-and-out performance the Superlight absolutely delivers. We've ranked it just behind the Razer Viper Ultimate, another high-end wireless ultralight mouse, due to the Razer's lower asking price, but either one could be a great choice depending on your preferences for shape, sensor and software.

4. Glorious Model O Wireless

modelowireless

69 grams • BAMF sensor • ambidextrous honeycomb design • 128x66x37mm • RGB

The Model O Wireless is another strong option. It's significantly dearer than the vanilla model, at closer to £80/$80, but that untethered feeling might be worth the premium. I found it performed extremely well in my testing, with the ambidextrous shape and extremely low weight of 69 grams contributing to comfortable in-game performance. However, latency was very slightly higher than some larger brands like Logitech and Corsair and if you use a high DPI setting you may notice some slight 'angle snapping', with mouse movements appearing straighter than they should. Hopefully, this can be fixed in a future software or firmware update, but it wasn't noticeable for me outside of specific testing for this issue.

Battery life is only average with RGB engaged - developing a low-latency, high-efficiency sensor to allow this is something only a handful of companies have really achieved - but Glorious have opted for USB-C recharging so that's at least convenient to top it up when needed. With RGB disabled, the mouse does manage around 70 hours of use according to Glorious. The Model O Wireless is doubtless a top-tier ultra-light, and one of the three best wireless ultra-lights alongside the legendary Logitech G Pro Wireless and the Razer Viper Ultimate.

6. Mountain Makalu 67

makalu

67 grams • PAW 3370 sensor • ergonomic honeycomb design • 127x70x42mm • RGB

The Makalu 67 is part of a new breed of ultra-light mice, designed to hit that low mass certain gamers crave without jeopardising durability. Rather than hexagons, the mouse uses a two-layer mesh with slats, which Mountain call a 'ribcage' design, and it does result in a sturdier-feeling mouse with less flex than other ultra-lights. Other modern touches include a PixArt PAW 3370 sensor, which has a lower lift-off distance and lower error rate than the already excellent PixArt 3389 - unsurprisingly, it performed extremely well in my testing. Other components, like the mouse button and scroll wheel, also use high quality components and feel good to use.

The lighting is also a bit more sensible than we've seen on some of the Makalu's competitors, in a ring around the scroll wheel area rather than issuing through the ventilated body. Another clever touch is the DPI system, which uses four tiny white LEDs to signify which of the four DPI settings you're using, making it easy to get to the setting you want without having to wiggle your mouse back and forth a few times. DPI and other settings can be adjusted in Mountain's Base Camp software (ah, branding!).

The shape here is interesting too. The Makalu is relatively large, measuring 70mm across and 127mm long, with a tall bump towards the centre of the mouse that nestles nicely in your hand. Ridges on the sides make it easy to pick up, but the left and right mouse buttons sadly don't include any 'comfort curves' which I do prefer to have. Regardless, the shape is solid and should suit anyone that prefers right-handed ergonomic designs. The mouse cable is also exceptional, with plenty of flexibility, and the mouse feels almost wireless as a result which is brilliant. I'd say this mouse will be most comfortable for those with medium to large hands. If you like the look of the Makalu's unique features, do give it a try - it may not be made by a major company, but it's clear that Mountain's ambitions are anything but ordinary.

Note: Mountain has tried to minimise plastic packaging and committed to helping Plastic Bank remove 25,000kg of plastic from the ocean. This of course doesn't affect gameplay but may make you feel slightly warmer and fuzzier inside...

7. Xtrfy M4

m4

66 grams • PMW 3389 sensor • ergonomic honeycomb design • 120x68x39mm • RGB

Xtrfy's Project 4 mouse was announced in the wake of the Model O, promising a mouse that's "light yet top-performing and durable... with a right-handed, ergonomic shape." A few months later, that's exactly what has been delivered, with a right-handed design that curls into the base of your thumb to make the mouse easy to grip and a honeycomb pattern to keep the weight low. The cable, scroll wheel, buttons and sensor are all solid, so if you like the shape and size you're sorted. The mouse is also one of the best-looking ultra-lights on the market, with RGB lighting, a light-up Xtrfy logo inside and a choice of five colours - black, white, blue, pink and 'retro' beige.

Counter-Strike superstar Zywoo and a few of his contemporaries use the M4 in competitive play.

8. Xtrfy M42

m42

59 grams • PMW 3389 sensor • ambidextrous honeycomb design • 118x63x38mm • RGB

The Xtrfy M42 is a smaller, ambidextrous take on the company's earlier M4. It's one of the best ultra-light mice for small to medium hands we've tested, ranking highly for its top-spec Pixart 3389 sensor, all-around RGB lighting and a super-flexible cable. Uniquely, the M42 comes with a choice of two back panels, allowing you to swap between a raised and less prominent bump. You can even use files from Xtrfy's website to 3D print your own design, which is super neat to see. Like the M4, the M42 is available in five variants: black, white, blue, pink and a unique retro colourway, making it also one of the most colourful gaming mice available.

9. Glorious Model D

modeld

68 grams • PMW 3360 sensor • ergonomic honeycomb design • 128x68x42mm • RGB

Another excellent ergonomic option for right-handers and the second in Glorious' planned ODIN series of mice, the Model D comes with the dependable PixArt 3360 sensor, a low weight of 68 grams and a pretty RGB-encrusted design. The Model D is a little taller and heavier than the Kone Pure Ultra, but comes with a better shoelace-style cable that feels almost wireless. Thanks to its low price, we reckon this is the best value right-handed ultra-light available and best suits those with medium to large hands.

10. Razer Viper Mini

vipermini

60 grams • PMW 3359 sensor • traditional ambidextrous design • 118x62x38mm • RGB

The Viper Mini is a stellar performer at its price point, packing a PixArt 3359 optical sensor, low latency optical switches and RGB lighting into a traditional (no-hole) design of just 60 grams. The feel of this mouse is superb for small and medium hands in fingertip or claw holds, while smaller hands can also palm the mouse easily. The soft cable is another strong point, although it's not quite as flexible as that offered by the likes of Glorious. The Viper Mini is an excellent value ultra-light mouse.

11. Roccat Burst Pro

burst

68 grams • PMW 3389 sensor • traditional ambidextrous design • 120x58x38mm • RGB

The Roccat Burst Pro is a solid evolution of Roccat's first ultra-light mouse, the Kone Pure Ultra. It uses an ambidextrous design this time, like the Roccat Kiro, making it suitable for left or right-handed use, unlike the Pure Ultra which was an ergonomic right-handed design. The first thing you're likely to notice when plugging this mouse in is this cool subsurface honeycomb design, which is revealed by RGB lighting below. This prevents dust or moisture ingress, a worry for some potential ultra-light purchasers, while still cutting weight and showing off that cool hexagonal pattern. The specs here are top notch, including a soft and flexible cable, Pixart 3389 optical sensor and Roccat's own Titan optical switches - which we loved in their Vulcan mechanical keyboards. The combination works well in game, and the weight of 68 grams is respectably low. If you like the design - and we do quite a bit - this is a strong choice, especially at its mid-range (for the ultra-light category) price point of £50.

12. Xtrfy MZ1 (Zy's Rail)

mz1

56 grams • PixArt 3389 • ergonomic honeycomb design • 111x53x37mm • RGB

The Xtrfy MZ1 is a unique mouse designed by veteran mouse reviewer Zy, with a unique shape that sets it apart - plus top-tier components from Xtrfy. Despite being relatively short and flat, design elements including a prominent back hump, deep comfort curves in the buttons and sculpted sides make this mouse surprisingly comfortable to wield. That applies even for those with relatively large hands, although the way you grip the mouse is necessarily different than most others I've tested and therefore there's a bit of a learning curve.

I love that the all of the areas that you grip don't have any holes in them, and that Xtrfy has also coated the internals to provide water and dust protection. The mouse creaks a little when held tightly, and the cable has frayed slightly where it rubbed on the sharp edge of a crummy mouse pad, but neither are genuine issues - I have zero qualms about the build quality here. The mouse can be configured entirely using on-board controls too, no software required. By default, you can adjust the lift-off distance, debounce delay and DPI setting, as well as customise everything about the lighting, from effect and colour to brightness and speed. This works nicely, and the key used for making most changes can be set as the F11 key afterwards so that it can be rebound to be used in games - handy!

Speaking of games: In FPS titles like Call of Duty Black Ops Cold War and Counter-Strike, the MZ1's low weight (56g), Kailh 8.0 switches and latest-gen Xtrfy flexible cable make it a great performer, with the potential for both quick flick shots and stable tracking. I used it for the entirety of my Black Ops Season 4 campaign, from levels 0 to 100, and consistently performed as good or better than with some of my all-time favourites like the Razer Viper Ultimate, Logitech G Pro X Superlight and Glorious Model O. Provided you can get over that initial hump of the unusual shape and slightly different grip style, I think this mouse is one of the best competitive options on the market right now. Suffice it to say, I'm looking forward to Xtrfy and Zy's next collaboration...

13. HyperX Pulsefire Haste

haste

59 grams • PMW 3335 sensor • ambidextrous honeycomb design • 124x67x38mm • RGB

The Pulsefire Haste is HyperX's first ultra-light mouse, but you wouldn't know by looking at it. It ticks all the boxes in terms of design and features - a safe shape with ventilation throughout, a recent (if not top) optical sensor, the Pixart 3335, a hyper-flexible cable and of course an impressively low weight of 59 grams. The Haste feels well made too, with no ominous creaking or unwanted movement when it's gripped tightly. HyperX make a big deal of their use of TTC Golden switches under each mouse button, and they do feel great - tactile, responsive and relatively light. The shape works well too, being roughly similar to the Zowie FK series, Razer Viper or Glorious Model O, making it a good choice for fingertip or claw grippers with medium to large hand sizes. For the asking price of $50, this is a great option that's well worth considering, even if it doesn't have a standout spec or feature that could catapult it into must-buy territory.

14. Cooler Master MM720

mm720_dual

49 grams • PMW 3389 sensor • ergonomic honeycomb design • 105x78x37mm • RGB

Definitely the most unusual mouse on this list, the MM720 offers a scuplted, ultra-wide shape that is gloriously comfortable for hours on end. The mouse was a little harder to get to grips with, perhaps due to that exaggerated design, but the extremely low weight of 49 grams and flexible cable means that it's still a reasonable choice for flicks in FPS - once you get used to it, anyway. The MM720 is also unusual in using LK optical switches rather than the more popular Omron, but I didn't experience a noticeable difference in my testing. I'm not sure whether this is down to the shape, the rather small holes or other design elements, but side flex is nonexistent here, and the mouse feels very solid in the hand. The scroll wheel is the only weak point for me, as it's quite smooth - I prefer more distinct, tactile steps but your mileage may vary. If you like a claw or fingertip grip - and especially if you were a fan of the CM Xornet or Spawn - this is a great mouse to try out.

15. Endgame Gear XM1r

xm1r

70 grams • PAW 3370 sensor • traditional ambidextrous design • 122x66x38mm • no RGB

The Endgame Gear XM1r is a great lightweight mouse with no RGB bling - just top quality components throughout, including a PixArt 3370 sensor, super thin PTFE mouse feet, Kailh 8.0 switches and a super-flexible cable. I normally take a few days to acclimate to a new mouse in high-pressure situations like CS:GO, but the XM1r's ambidextrous shape, matte coating and clicky buttons suited me down to a tee from the first moment. (As well as the white matte model I tested, there are three other designs: black matte, see-through black glossy and see-through black matte.)

The only real downside to the XM1r is the software; weeks after launch, it's still impossible to set the DPI or perform other basic tweaks as the proudly "developed in Germany" XM1r configurator remains unavailable for download. Hopefully we'll be able to update this listing in a few weeks and push the mouse a few more places up our list, as the XM1r is close to being one of the best value ultra-lights on the market.

Note that the earlier XM1 remains available, which doesn't suffer from the same software situation. This model uses a PixArt 3389 sensor and Omron switches; apart from these components and different finish options the mice are identical.

16. SteelSeries Prime, Prime+ and Prime Wireless

prime_mice

69 grams • TrueMove sensor • traditional ergonomic design • 125x68x42mm • RGB

SteelSeries recently released not one but three ultralight mice, all with the same non-ventilated ergonomic form factor but different sensors and connection methods. The Prime and Prime+ are wired mice, weighing 69 and 71 grams, with the Prime+ differentiating itself with a higher-tier sensor and a bottom OLED screen that allows you to change the settings on the mouse itself. The 80g Prime Wireless uses the TrueMove Air sensor, which is optimised for battery life. The shape here is quite different to other mice I've tried recently, with a narrow front and wide base suitable for claw or palm grips. Some edges here are quite sharp and straight, and the mouse - like the Xtrfy MZ1 - may require some experimentation to get a grip style that suits the shape.

After this adjustment period though, you're left with a capable ultra-light mouse that feels comfortable to use, has tactile optical-magnetic switches and doesn't overdo the RGB. The mouse skates and cable are both good too, if not quite the best we've seen in the ultra-light category. However, there are some downsides to be aware of too. Clicks don't feel quite as responsive as on other mice, the side buttons are a little small and the wireless Air model takes a few seconds to successfully re-pair. I also noted the Air become a little jittery at one point during my testing, perhaps due to entering a power-saving mode or wireless interference. However, this didn't re-occur and seems to be a one-off incident.

Based on my testing, the upgraded sensor and OLED screen of the Prime+ don't quite justify its higher price point, so I'd recommend the entry-level Prime as the standout option of the three with the Prime Air being a decent wireless option - albeit against very stiff competition in the form of the Razer Viper Ultimate and Logitech G Pro X Superlight. Overall, it's a good outing from SteelSeries and it's great to see them continue to innovate in terms of shapes, something that's becoming increasingly rare in the mouse industry.

17. Roccat Kone Pure Ultra

pure

66 grams • PMW 3381 sensor • traditional ergonomic design • 115x70x39mm • RGB

The Roccat Kone Pure Ultra is one of the most normal-looking ultra-lights on this list, with a traditional shell in an ergonomic right-handed shape that suits palm or claw grips. Despite its appearance, the Pure Ultra ranks alongside honeycomb designs like the Xtrfy M4 in terms of overall weight, with considerable savings having been made inside while keeping gaming mice staples like RGB lighting and an accurate optical sensor. The Pure Ultra comes with a soft touch matte finish which is very comfortable to use. If you hate the look of holey mice, whether through genuine trypophobia or just preferentially, this is the ultra-light for you.

18. MSI Clutch GM41 Lightweight

gm41

65 grams • PMW 3389 sensor • ambidextrous honeycomb design • 130x67x38mm • RGB

The Clutch GM41 is the first ultra-light mouse we've seen from Taiwanese giants MSI, yet it gets a lot right. The 65 gram weight is low for a mouse of this size, yet the GM41 doesn't rely on the honeycomb design that's proven divisive amongst more mainstream consumers. It also comes with a top optical sensor, the PixArt 3389, and offers a comfortable ambidextrous design. Diagonally patterned side grips help with rapid repositioning, and clicking feels good thanks to well-respected Omron and Huano switches for the primary and side buttons, respectively. The only real failing is the cable, which is much stiffer than we'd expect for an ultra-light. This makes it harder to move at high speeds, and tends to get caught more often than the shoelace-style cables found on most other ultra-lights. Still, the weight, shape, build quality and sensor are all good, so the GM41 still deserves a recommendation, especially at a relatively modest price point of £41.

19. Cooler Master MM731

mm731_1200x630

59 grams • PAW 3370 sensor • traditional ergonomic design • 122x69x39mm • RGB

The MM731 is a good mouse dogged by controversy. Early models reportedly exhibited flexing bodies and squeaking buttons, while the firmware added a larger-than-usual input delay. Cooler Master seems to be handling the issues with some grace, swapping those early models for replacements with better build quality free of charge, and improving the firmware to reduce the input delay. At the time of writing, October 2021, a complete firmware fix has yet to be deployed but is being promised. The reason we're still recommending this mouse is that we believe CM will do the right thing - and there is a ton of potential here thanks to the mouse's shape and features.

First off, this is a tri-mode mouse, capable of being used via low latency 2.4GHz wireless, higher latency Bluetooth for mobile devices and wired, with a modern-style USB-C flexible cable provided. At 59 grams, this incredibly light for a solid-bodied wireless model - and there is an MM730 that is wired only at a lower price and weight. The shape is a comfortable right-handed ergonomic affair, with a long sloping body and a shallow hump about three quarters of the way back. The overall appearance is quite professional, with a matte black finish and little ornamentation save for the RGB-lit Cooler Master hexagonoid.

The software here is a new one for CM, called MasterPlus, and it's cleanly designed with all of the options you'd need. I particularly appreciate that you can hold down the middle mouse button then click the left, right, back or forward buttons to access four additional functions - like running macros, changing the lighting colour or changing profiles. It's a sensible touch, and one that ought to be adopted by more brands than Cooler Master and Roccat.

Once the MM731's latency issue is fixed, I think it'll rocket up the charts - as although this mouse is much more expensive than CM's earlier MM710 and MM720 ultra-lights, it is also very good.

20. Marsback Zephyr Pro

zephyr

69 grams • PixArt 3389 • ambidextrous honeycomb design • 131x66x41mm • RGB

This mouse is truly one-of-a-kind. The Zephyr Pro is an ultra-light mouse that somehow contains a small fan, cooling your palm through the rodent's honeycomb design. The fan is nearly inaudible - I noticed it only playing late at night - and provides a modest but effective amount of airflow given its small size. The weight of the mouse remains low, at 69 grams, and the balance hasn't been affected badly either. The internals - PixArt 3389 sensor, Omron switches - meet the industry standard and the RGB lighting is great too, with the fan itself illuminated as well as the scroll wheel and underskirt. Basic software and a good flexible cable complete the loadout.

If you're looking for an ambidextrous mouse, with a similar shape to the Zowie FK series and the Glorious Model O and you often get sweaty hands, this is a surprisingly legitimate option. The mouse normally costs $69, but Marsback are offering it to Digital Foundry readers for $10 off with the code DFONLY. Black and white colourways are available, both with a matte coating that jibes nicely with the focus on cooling.

21. Trust Gaming GXT960 Graphin

graphin

74 grams • PMW 3325 sensor • ambidextrous honeycomb design • 126x63x40mm • RGB

The GXT960 Graphin from Trust Gaming is an example of a design produced by several smaller brands, featuring a honeycomb mouse with a mounted internal diffuser that spreads the RGB lighting produced by a few LEDs across the entire chassis of the device. The Graphin weighs 74 grams, making it among the heavier of our ultra-light options, but performed well in our testing thanks to its safe shape, reminiscent of the G Pro Wireless.

As is often the case with mass-market designs, the cable isn't ideal - we normally prefer a very flexible 'shoelace' cable that provides an almost wireless feel, but the Graphin instead features an inflexible braided cable more typical of traditional gaming mice. It's not awful, but it's a point that could be improved in a future iteration. Likewise, the sensor, which we believe to be a PixArt 3325 or similar, was fine in our testing but higher-spec versions tend to be more popular in this market segment. The button response could also be improved, as the left and right click buttons have quite a soft and spongey feel.

Despite these differences, the Graphin is still a good ultra-light mouse and worth considering if it's available at a cheaper price than some of the other entries on this list.

Ultralight mice: key specs

Here's how the mice rank in terms of weight alone, plus some other key specifications - such as the sensor on board and dimensions. We've also classified the designs in two dimensions: "honeycomb" or "traditional" based on whether they have external holes and "ambidextrous" or "ergonomic" based on whether the left and right sides of the mouse are similar shapes. Symmetric mice are the only viable option for left-handers, but many right-handers prefer this style as well.

Frequently asked questions

How to measure hand size for a gaming mouse

Your hand size will determine how comfortable a given mouse is to use. Most ultra-light mice will be perfectly usable for the vast majority of hand sizes, but if you have particularly large or small hands then opting for a matching mouse may offer the best results. To find your hand size, keep your fingers together and measure from the tip of your longest finger to your wrist.

  • Small hands: Less than 170mm (6.7")
  • Medium hands: Between 170 and 195mm (6.7" - 7.7")
  • Large hands: More than 195mm (7.7")

You can also measure your hand's width from the bottom of your hand, across your knuckles and past your thumb. You can compare these two hand measurements, length and width, with a mouse that you're considering. A mouse that is about 60 per cent in both dimensions should be suitable for your hand size.

For example, my hand size is 200mm x 100mm, so I personally look for mice that are around 120mm x 60mm. Different grip styles can also influence your ideal mouse size; claw and fingertip grips will hover around the 60 per cent mark, while palm grips are flatter and therefore mice that are closer to 70 per cent of your hand size will feel more comfortable.

Won't dirt get in the holes?

I don't think it matters. I've been testing ultra-light mice since May 2019 and I can't see any visible dust or dirt in even my oldest mice. I also haven't noticed any change in performance over time. If I do, I will update this article accordingly.

Furthermore, there aren't really any components under the holes that would be affected by dirt - just a PCB and potentially RGB lighting, with moving elements like button switches generally covered up. I wouldn't advise eating messy foods or spilling drinks onto an ultra-light mouse, but I wouldn't recommend that with any other kind of computer peripheral either. If you're concerned about this, consider traditional full-body mice like the Roccat Kone Pure Ultra, Endgame Gear XM1 or Logitech G Pro Wireless.

Are ultra-light mice worth it?

Yes, I'd say so. You'll see the greatest benefits to a lighter mouse in fast-paced FPS and battle royale games where aiming quickly and accurately is of paramount importance. Outside of these games, all of the medium to large ultra-light mice I've tested have been perfectly comfortable for general computer use as well.

Most importantly, while there are very expensive ultra-light mice - think of the rare Finalmouse Ultralight 2 and premium Logitech G Pro Wireless - there are also plenty of more affordable options around the £45/$50 mark. Many retailers will accept returns within a certain time window if the mouse is in a saleable condition, so if this is the case for you then it's well worth trying out one of the ultra-lights we've highlighted just to see how you get on.

What do you think of the rankings and which ultra-light is your favourite? Let us know - and iIf there's an ultra-light mouse you think we missed, why not let us know on Twitter @wsjudd or @digitalfoundry? We'll be keeping a close eye on the comments too.

Our videos are multi-gigabyte files and we've chosen a high quality provider to ensure fast downloads. However, that bandwidth isn't free and so we charge a small monthly subscription fee of €5.
