Greatest keyboards for 2025

Logitech

Connectivity: Bluetooth and Logi Bolt USB receiver | Dimension: Full-size format | Materials: Plastic chassis with low-profile scissor switches | Switches: Scissor switches | Sizzling-swappable: No | Backlight: Sure, good illumination with ambient gentle sensors | Software program: Logi Choices+

Logitech is aware of how you can make a strong keyboard, and the Grasp sequence has been a superb one over the previous few years. The MX Keys S is the most recent full-sized version and it combines a low-profile design with snug keys and useful customization instruments. It appears fairly glossy in black, white or graphite, measuring just below 17 inches in width and solely 0.8 inches excessive off your desk. Its spherically-dished keys cradle your fingertips each time you press, and whereas I wouldn’t go up to now to say they completely prevented me from placing any typos on this information, the form positively helps greater than different, flatter keycaps I’ve used.

It is a backlit keyboard with “good illumination,” which simply means the backlight will kick on when your arms strategy the board and regulate relying on the lighting in your atmosphere. I’ve a good quantity of pure gentle in my residence workplace throughout common working hours, so I opted to show the backlight off — should you do the identical, you may rise up to 5 months of battery life out of the MX Keys S (Logitech estimates 10 days with good illumination on). The keyboard has a built-in USB-C port for charging as nicely.

Along with the low-profile design that also features a quantity pad, the most important kickers for the MX Keys S are its extensive compatibility and customizable options with Logi Choices+. This peripheral works with Home windows, macOS, ChromeOS, Linux and iPadOS, and it has three machine pairing buttons so you may join it to as much as three gadgets directly and change between them as mandatory. Logi Choices+ is free software program that many Logitech equipment use, and for the MX Keys S, it lets you customise brightness ranges and period, set good actions (one-key shortcuts you program to your liking) and extra.

The Grasp Sequence additionally features a “mini” version of this keyboard that nixes the quantity pad and $10 from the worth tag. I’ve used that and luxuriate in it as nicely, however if you’re solely saving $10, the full-sized model looks like a greater worth. Can you discover cheaper wi-fi keyboards than both of those? After all. However Logitech’s experience on this house actually shines within the Grasp sequence, and with the MX Keys S specifically because it stands out as a high-quality wi-fi keyboard with a bunch of additional options at a good value. — Valentina Palladino, Deputy Editor

Logitech’s Pop Icon Keys takes a variety of notes from the Grasp sequence and interprets them right into a extra enjoyable (and cheaper) bundle. The $50 keyboard doesn’t embrace a quantity pad, however as a substitute has a row on the precise facet that features 4 buttons you can customise utilizing Logi Choices+. I’ve mine programmed to activate macOS’ mission management, open the emoji keyboard and to maneuver web page up and down, respectively. However these aren’t the one buttons you may customise — 11 of the highest perform keys will also be programmed to your liking as nicely.

The Pop Icon keycaps have a slight indentation to them, although not as dramatic as these on the Grasp sequence keys, and the typing expertise is a cushty and quiet one general. Whereas this isn’t billed as a journey keyboard, it’s sufficiently small to suit into an ordinary work bag or backpack, so you may take it with you with out a lot problem.

You’ll be able to join the Pop Icon keys to as much as three gadgets directly and change between them simply, and the keyboard helps macOS, Home windows, Linux, Chrome, iPadOS, iOS and Android gadgets. In addition to there being no choice for a quantity pad configuration, arguably the most important draw back to this keyboard is the truth that it runs on two AAA batteries. Logitech estimates it’ll last as long as three years earlier than you must exchange them, so possibly that’s a professional for some slightly than a con. I additionally admire that, when linked to a Mac laptop over Bluetooth, you may nonetheless monitor the Pop Icon Keys’ battery life from the Bluetooth menu.

That is additionally an awesome value for a strong wi-fi keyboard. Logitech itself makes even cheaper ones, however the Pop Icon Keys strikes an excellent stability between design and capabilities at this value level. The largest query, should you select this keyboard, is which colorway you fancy probably the most out of the 5 choices. — V.P.

When you’re able to make a critical dedication to growing your ergonomics, I like to recommend the ZSA Voyager.

However the ergonomic advantages are equally important. The absolutely cut up board lets me open up my arms and chest. On days once I’m feeling notably tight, I’ll put the 2 halves a full foot aside. Relocating the return, command and forward-delete key to the thumbclusters saves me from shifting my arms across the board and the layers perform permits for much extra performance than an ordinary keyboard.

That stated, it additionally provides to the safety of my laptop, making all of it however unattainable for different individuals to kind with the Voyager. It comes with magnetic knobs for the middle tenting function, however I want it got here with the choice to elevate the center somewhat greater. I created additional elevate by including rubber bumpers to the board, however for the worth, it’d be good to not need to MacGuyver it. Nonetheless, at any time when I’m compelled to make use of an everyday keyboard, I really feel like I am toiling within the typing pool at Sterling Cooper. — A.S.

Mixed with a number of layers of froth, these presses have a delightfully poppy and even sound.

We examined the tenkeyless Q3 Max, however Keychron presents a number of different size and layout options as nicely. Every can join over a wi-fi dongle, Bluetooth or USB-C and contains additional Home windows- and Mac-specific keycaps within the field. There are nonetheless issues to nitpick — there’s a faint little bit of rattle to a few the bigger keys; you may’t regulate the keyboard’s peak; and Keychron’s one-year warranty is fairly brief — however should you simply need to purchase a mechanical keyboard that delivers a premium expertise from the leap, it will get you there. – Jeff Dunn, Senior Reporter

We advocate the Keychron C3 Pro if you wish to spend as little as potential for a pleasant mechanical keyboard. It’s a stellar worth at just below $50, with factory-lubricated switches, a gasket mount, a number of layers of inner foam and different touches we don’t often see on this value vary.

What to search for in a keyboard

Design

Dimension

The very first thing you’ll need to think about in the case of your subsequent laptop keyboard’s design is measurement. There are a variety of various keyboard layouts to select from, however the commonest are full-sized, tenkeyless and people smaller than tenkeyless.

Full-sized keyboards, or 100%, embrace a perform row on the prime and an entire numpad with arrow keys on the precise facet, together with all the remainder of the alphanumeric keys you’d anticipate on an ordinary QWERTY format. Tenkeyless, or 80 %, removes the quantity pad however retains the arrow keys and the perform row, decreasing the general width measurement of the board by a good quantity. Compact keyboards preserve issues extremely easy by together with solely the alphanumeric keys and modifiers like Alt, Shift, Ctrl and others they usually come in several sizes like 60 %, 65 % and extra. These are the most well-liked sizes on the market, however you could find loads of different designs that embrace completely different mixes of keys together with the usual letters and numbers all ought to have.

Except for measurement, there are two different huge classes that you may use to outline a keyboard: ergonomic and mechanical. Ergonomic keyboards are designed with, you guessed it, higher ergonomics in thoughts, making an allowance for the place you must place your fingers, arms and forearms to keep up correct posture. Individually, mechanical keyboards use mechanical switches (of which there are a lot of varieties) that differ significantly from the membrane or scissor-switch keyboards you’ll discover dominating most wired and wi-fi choices extensively accessible at the moment. We’ve guides to the most effective ergonomic keyboards and greatest mechanical keyboards, however we’ll summarize what you must find out about each right here.

Ergonomic keyboards

When you take care of discomfort from working at a pc all day, ergonomic keyboards may help. These specifically designed boards re-orient the keys, permitting you to carry your elbows farther aside and keep a straighter line out of your forearms to arms. Some individuals discover this refined change extra snug.

Ergonomic keyboards sometimes fall into two classes: Alice and cut up keyboards. The previous is a single unit with an A-shaped hole within the heart of the keys. Cut up fashions are available in two separate items which you’ll organize as you want in your desk. Extra ergonomic options like tenting and unfavourable tilt could make typing really feel much more snug, and are sometimes accessible on each Alice and cut up boards. Tenting raises the center of the keys up so your arms tackle extra of a “handshake” place. Unfavorable tilting lowers the highest of the keyboard to maintain your wrists angled downward as a substitute of again in the direction of your forearms.

The best way the keys are organized on the keyboard could make typing simpler as nicely. Historically, keyboards are staggered, with one row of letters barely offset from the row beneath it. Columnar keyboards organize the keys in a grid of rows and columns. This type takes somewhat getting used to, however some individuals discover it permits them to kind sooner. You can even make the keys of some keyboards do extra than simply produce letters. Programmable boards allow you to map shortcuts and different capabilities, together with macros, which can preserve you from reaching for the mouse fairly so typically, saving you time and presumably pressure as nicely.

Mechanical keyboards

Mechanical keyboards have blown up in recognition as extra individuals have been thrust into creating their very own workspaces at residence. It’s simple to see why: In comparison with a conventional membrane keyboard, an excellent mechanical board is extra sturdy, extra satisfying to press and, most significantly, infinitely extra customizable. The perfect of them often include a value premium, however even some cheaper fashions allow you to “hot-swap” between keycaps, switches and different supplies, letting you tinker with completely different typing sensations and sound profiles till you discover a mixture that greatest expresses your preferences.

Would you like every press to really feel deep and full or quick and lightweight? Do you want them to sound loud and clacky or virtually totally muffled? Do you favor your keycaps to look subdued {and professional}, full of RGB lights or written in an Elvish language from The Lord of the Rings for some purpose? With the precise new keyboard, it’s all as much as you — the one issues actually holding you again are your creativeness and your pockets.

We’ve a devoted shopping for information that digs deeper into the important thing elements to think about when shopping for a mechanical gaming keyboard, so we encourage you to take a look at that for a full rundown. To maintain issues high-level, probably the most influential a part of your buy is your keyboard’s change kind. These little mechanisms slot beneath the keycaps and customarily have the most important impact on how your keyboard feels and sounds as you kind away.

You’ll be able to broadly separate mechanical switches into three buckets: linear, tactile and clicky. Linear switches really feel {smooth} all the best way down; they’re typically standard with avid gamers since they are typically gentle and quick to actuate. Tactile switches create a tangible “bump” sensation partway by way of a press; many individuals who spend all day typing want them as a result of they clearly affirm every press with out (all the time) being all that loud. Clicky switches are functionally much like tactiles however make an audible “click on” sound to match the bump; your coworkers could hate them, however others love the full-throated sense of suggestions they supply. To be clear, simply because two switches fall inside the identical bucket doesn’t imply they really feel or sound precisely the identical. The one means to determine which change works greatest for you is to do your analysis and, ideally, strive some out for your self.

Different keyboards have a mechanical-style really feel however are constructed on completely different mechanisms totally. The new new pattern in gaming-focused keyboards, for instance, is Hall effect switches, which use tiny magnets to register keystrokes and allow you to customise the sensitivity of every press. Optical switches, in the meantime, provide comparable performance by changing the bodily contact level of a typical mechanical change with a beam of infrared gentle. Extra just lately, we’ve seen a couple keyboards launch with inductive switches, which might work like magnetic switches but use inductive coils within the keyboard’s printed circuit board (PCB) to cater to all switches collectively and don’t require a sensor for every particular person change. We contact on a few magnetic-switch keyboards in our picks under, however for a fuller breakdown of this kind of tech, we advocate you try our devoted shopping for information to the best gaming keyboards.

Connectivity

You’ve bought two choices right here: wired or wi-fi. Wired keyboards sometimes have an connected cable that plugs right into a USB-A or USB-C port in your laptop (or docking station), though some include cables that may be eliminated. Wi-fi mechanical keyboards hook up with your machine both through Bluetooth or a wi-fi receiver dongle. There’s all the time the prospect of some latency with wi-fi keyboards, so preserve that in thoughts should you’re selecting one up to make use of primarily with a gaming PC. After all, you’ll solely have to fret about battery life with Bluetooth keyboards.
