Demand for lighter mice first came from the esports world, where making movements as quickly as possible is crucial, and having a lighter mouse helps. That said, you may also want a lightweight option that's easy for traveling. Many lightweight mice have hexagonal cutouts in the body to save weight; these are called honeycomb mice. For a time, the best lightweight gaming mouse was unquestionably the best honeycomb mouse, but recently, some solid body designs are getting light enough to be considered. We define anything under 85g as lightweight, but it's important to know what you're looking for. Click latency, build quality, and connection types are key concerns for competitive gaming. For long gaming sessions, you'll want good ergonomics.
We've tested over 240 mice, with over 80 we'd consider lightweight. Below are our top picks for the lightest mouse for several uses. See our recommendations for the best mouse, the best gaming mouse, and the best ergonomic mouse.
Weighing only 45 grams, the Finalmouse Starlight-12 Small is the lightest mouse we've tested. It has a honeycomb body with an embossed filigree design and two side buttons on the left. It feels exceptionally well-built and has a low-profile, ambidextrous shape well-suited for smaller hands using any grip type. The top shell is made of magnesium alloy and is very sturdy. However, the underside is made of plastic to allow the wireless signal to escape.
You can connect it wired or wirelessly with its receiver, and it has a rechargeable battery. Its CPI range isn't as wide as most other high-end gaming mice, but it will likely be sufficient for most gamers. It also has a polling rate of 1000Hz, a very low lift-off distance, and good click latency. Its mouse feet glide very smoothly on mousepads or directly on desks, and its paracord-like charging cable is lightweight and flexible.
Unfortunately, it's a very small mouse that isn't well-suited for larger hand sizes. Also, there isn't any software for customization, there are only four default CPI settings, and the charging cable uses an older Micro-USB connection rather than the newer USB-C. Furthermore, because Finalmouse only releases its mice in drops, at this moment, you can only purchase this mouse through third-party resellers, and it can be very expensive. Nevertheless, this is an exceptional gaming mouse and the lightest mouse we've tested.
The Glorious Model O is the best lightweight mouse for gaming that we've tested. At 67g without its cable, it falls roughly in the middle among the lightest mice we've tested, but it's the sum of its parts that makes it our best pick. It has a plastic honeycomb body that feels very sturdy and a comfortable ambidextrous shape that's well-suited for all grip types and most hand sizes.
It also has a very lightweight and flexible cable and PTFE mouse feet that glide very smoothly despite their sharp edges. Performance-wise, it has great click latency, a very low lift-off distance, a wide CPI range, and a very consistent sensor. It also has customization software that allows you to adjust the RGB lighting, change sensor settings, and remap all buttons, including the scroll wheel and DPI switching button.
Unfortunately, the software is only compatible with Windows, you can only adjust the CPI by increments of 100, and its relatively large body makes it unsuitable for small hands. However, there's a smaller version with similar performance, the Glorious Model O-, which is ideal for small hands using any grip type. Altogether, the Glorious Model O has well-balanced features and is one of the best gaming mice we've tested, making it a great choice for any gamer who prefers a lightweight mouse.
If you'd prefer a wireless connection, the best lightweight gaming mouse we've tested is the Logitech G PRO X SUPERLIGHT. It weighs only 59g, which is impressive as it has a solid outer shell and a rechargeable battery. There's also a compartment within the mouse to store the USB receiver when not in use.
Its click latency is excellent, and you can precisely adjust the set CPI in increments of 50 within a very wide range, so you'll find a sensitivity setting that works for you. Using the companion software, you can reprogram all of its buttons, and you can also assign a G-Shift button to enable a second layer of commands. Since it connects wirelessly, you won't need to worry about a cable causing additional drag. Also, its high-quality feet offer a smooth gliding experience across desks and mousepads.
Unfortunately, it's relatively expensive. Its rubber charging cable uses a micro-USB connector rather than a newer USB-C standard, which is disappointing given the mouse's high price point. With that said, it's an excellent option if you're looking for a lightweight mouse for gaming, and it's one of the best wireless gaming mice that we've tested.
The best lightweight gaming mouse with a more ergonomic shape that we've tested is the Cooler Master MM720. Weighing only 54g without its cable, it's extremely light, with a honeycomb cutout pattern on the top and sides of the mouse. It has a right-handed shape with a groove on the right side for your ring finger.
It's well-suited for palm and claw grips, although people with larger hands may feel like the mouse is too small to grip comfortably. It has customizable RGB backlighting, and you can reprogram all of its buttons, as well as set a Combo Mode that gives you a second layer of controls for as long as you hold the scroll wheel button. Performance-wise, it has a very low lift-off distance, an adjustable CPI within a wide range, and very low click latency.
Unfortunately, the sensor is quite inconsistent, and it undershoots the set CPI more during quick mouse movements than slow ones. Also, the plastic it's made of doesn't feel very sturdy, and it creaks if you press it hard enough; however, this shouldn't be an issue during regular use. All in all, this is a fantastic choice if you're looking for an ultra-light gaming mouse with a more ergonomic shape.
The best lightweight mouse for travel we've tested is the Microsoft Arc Mouse. At 82g, it's slightly heavier than some other mice on this list, but it's still light. It has a unique, collapsible design, so you snap the mouse into an arced position to turn it on and flatten it to turn it off. While flattened, it's extremely thin, making it easy to slip into a laptop bag while on the go.
It connects wirelessly with a Bluetooth connection, so you don't have to worry about carrying around a USB receiver. It also uses two AAA batteries for power, so a charging cable isn't necessary. Using Microsoft Mouse and Keyboard Center, you can swap the L/R clicks, which is great, especially if you're a left-handed user. You can also program a three-finger click gesture command. Though there's no physical scroll wheel, you can scroll vertically and horizontally by swiping your finger up and down or side to side on the button area.
Unfortunately, the three-button click doesn't work by default on macOS, and there's no compatible software for you to reprogram it. With that said, it's a good choice if you're looking for a lightweight mouse to bring with you on the go.
If you're looking for something more affordable, check out the Logitech Pebble M350. It doesn't feel quite as sturdy as the Microsoft Arc Mouse, and you can't program any of its buttons, but it's much less expensive, and you can use it wirelessly either with its USB receiver or Bluetooth. It weighs the same as the Microsoft mouse at 82g, and although it doesn't have software for customization, all of its buttons work in Windows and macOS. Because of its low, flat-profile shape, it's only suitable for a fingertip grip.
If you typically prefer a claw or palm grip and are interested in a sturdier-feeling option with programmable buttons, go with the Microsoft mouse. If you're comfortable using a fingertip grip and are looking for something more affordable with added wireless connectivity options, get the Logitech.
The best lightweight mouse in the budget range that we've tested is the Razer Viper Mini. At 61g, it's lighter than the original Razer Viper, but it still maintains the same ambidextrous design. Its smaller size is comfortable for any hand size to use with a fingertip grip, though it's too small for larger hands to comfortably use a palm or claw grip.
Its click latency is remarkably low, and its CPI range should be wide enough for most gamers. Using the companion software, you can adjust the set CPI in increments of 100. You can also reprogram the two side buttons and assign a Hypershift button to enable a second layer of commands. It also has high-quality feet and a flexible cable, so you won't have to worry about extra drag on desks or mousepads.
Unfortunately, its minimum lift-off distance is higher than some other gaming options, and its sensor is fairly inconsistent and tends to overshoot the set CPI during slower movements. It also lacks the two buttons on the right side that the larger versions in the Viper lineup have, so it's less viable of an option for left-handed users. With that said, it's an excellent choice if you're looking for a lightweight gaming mouse on a budget.

Our recommendations above are what we think are currently the lightest mice that are the best picks for the most people.

If you would like to do the work of choosing yourself, here's the list of our lightest mice. Be careful not to get too caught up in the details. While no mouse is perfect for every use, most mice are great enough to please almost everyone, and the differences are often not noticeable unless you really look for them.
