Short answer: for long typing sessions, choose a keyboard by four things, in this order: a layout small enough to keep your mouse close, switches with a light and consistent force (around 45 to 55 cN suits most people), a flat or slightly downward angle so your wrists stay straight, and a connection that does not drop. Brand, lighting and keycap colour matter far less. And no keyboard fixes a desk that is the wrong height, so check that first.
Why does the keyboard matter if you type all day?
Because you repeat the same small movements thousands of times an hour. A few grams of extra force, a wrist bent upward by the keyboard's feet, or a mouse placed 20 cm too far to the right all add up over an eight-hour day. Mechanical keyboards are popular with people who write and code for a living because each key has its own switch, the feel is consistent across the board, and parts can be changed.
Which switch type suits long typing?
A mechanical switch is a small spring-loaded mechanism under each key. There are three main families, and Cherry's own specifications are a useful reference because many other brands copy them:
| Switch (Cherry MX) | Type | Force | Pre-travel | Total travel |
|---|---|---|---|---|
| MX Red | Linear, smooth all the way | 45 cN | 2.0 mm | 4.0 mm |
| MX Brown | Tactile, a small bump, no click | about 55 cN at the bump | 2.0 mm | 4.0 mm |
| MX Blue | Tactile and clicky | 60 cN | 2.2 mm | 4.0 mm |
| MX Silent Red | Linear, dampened | 45 cN | 1.9 mm | 3.7 mm |
| MX Low Profile Red | Linear, shorter | 45 cN | 1.2 mm | 3.2 mm |
Pre-travel is how far the key moves before it registers. Total travel is the distance to the bottom. 1 cN is roughly 1 gram-force.
How to choose:
- Tactile switches (the Brown type) tell your finger the key has registered, so you can learn not to press all the way down. Many heavy typists prefer them for that reason.
- Linear switches (the Red type) are light and smooth. They suit people with a light touch; heavy-handed typists tend to bottom out on every stroke.
- Clicky switches (the Blue type) are satisfying but loud. In a shared office or on video calls, colleagues will hear every word.
- Low-profile switches shorten the travel and lower the keyboard's height, which can reduce how much you bend your wrists upward. Kailh's popular Choc V2 low-profile switches have 3.2 mm of total travel and forces from 43 to 48 gf.
If you can, try a switch tester, a small board with one of each switch, before buying a full keyboard. Feel is personal, and specifications only narrow the choice.
What about Hall-effect (magnetic) switches?
Hall-effect switches detect a magnet's position instead of relying on two metal contacts touching. Wooting, one of the companies that popularised them, explains that this lets you set the actuation point per key, from about 0.1 mm to nearly the full travel. They are built mainly for gaming, but a typist could set a slightly deeper actuation point to reduce accidental keypresses. They cost more than standard boards.
Which layout size is best for long sessions?
Keyboard sizes are described by how many keys they keep:
| Layout | Keys (approx.) | What you lose |
|---|---|---|
| Full-size | 104 | Nothing |
| Tenkeyless (TKL, "80%") | 87 | The number pad |
| 75% | about 84 | Number pad; keys packed closer together |
| 65% | about 68 | Also the function row |
| 60% | about 61 | Also the arrow keys and navigation cluster |
For long sessions, a tenkeyless or 75% layout is the sweet spot for most people. The reason is the mouse, not the keyboard. OSHA's workstation guidance says to keep the mouse close to the keyboard, because reaching for it pulls your elbow away from your body and makes you hold your arm up. A full-size board pushes the mouse about 8 to 9 cm further out; Logitech notes that a tenkeyless board lets you position the mouse closer to the centre of your body.
Keep a full-size board if you enter numbers all day. Engineers working through spreadsheets and calculation sheets may genuinely need the number pad; a separate numpad placed on the left is an alternative.
Smaller than 65% saves more space, but relies on shortcut layers for arrows and function keys. That is fine for some people and a constant annoyance for others, especially when editing documents.
How should the keyboard be angled?
Most keyboards have fold-out feet at the back, and most people use them. Ergonomics guidance says otherwise:
- OSHA advises that wrists should not bend up or down or to either side, that elbows should be about the same height as the keyboard, and "do not use keyboard feet if they increase bending of the wrist."
- Cornell University's ergonomics group recommends a keyboard tray that can tilt the keyboard slightly away from you, called negative tilt, placing the keyboard just below seated elbow height.
Practical translation: keep the feet folded, set the keyboard low, and if the keyboard is tall, as many mechanical boards are, use a palm rest level with the front edge so your wrists are not bent upward. Treat the rest as a place to pause, not somewhere to anchor your wrists while typing.
Are split and ergonomic keyboards worth it?
Split keyboards separate the two halves so your hands sit shoulder-width apart, and tented models raise the middle. They look like the obvious answer, but the evidence is mixed. Cornell notes some research evidence of reduced discomfort from less sideways wrist bending, yet its general guidance says there is no consistent evidence that most split designs produce substantial postural benefits, and "for most people a regular keyboard design works just fine if it's put in the proper neutral position." OSHA reaches a similar conclusion.
So a split board is worth trying if a normal keyboard feels uncomfortable even when correctly positioned, or if you have broad shoulders. Expect one to two weeks of slower typing while you adjust. If you already have pain when typing, talk to an occupational health professional rather than relying on a keyboard to solve it.
Which other features are worth paying for?
- Hot-swap sockets. Switches pull out and push in without soldering, so you can change the feel later or replace a faulty switch. This is the best insurance against buying the wrong switch.
- PBT keycaps. PBT plastic resists the shiny, worn look that cheaper ABS keycaps develop on the most-used keys after months of heavy typing.
- Keycap profile. Sculpted profiles such as Cherry or OEM, where each row is angled slightly differently, are easier for touch typists than tall, uniform ones.
- Remappable firmware. Boards that support the open-source QMK firmware, or the VIA configurator built on it, let you move keys: for example, putting Escape or Delete where they are easy to reach, or turning Caps Lock into something useful.
- Wireless that does not drop. A 2.4 GHz USB receiver is usually more stable and responsive than Bluetooth; Bluetooth is convenient for switching between a laptop, tablet and phone and uses less battery. Tri-mode boards offer both plus a cable. For typing, either wireless mode is fast enough; for a desk that never moves, a cable removes the question entirely.
A sensible setup for a full working day
- Set the chair and desk height first, so your elbows are at about keyboard height.
- Choose a tenkeyless or 75% board unless you need a number pad.
- Start with tactile or light linear switches around 45 to 55 cN, preferably on a hot-swap board.
- Fold the feet away and add a low palm rest if the board is tall.
- Put the mouse right next to the keyboard.
- Take short breaks; no switch design replaces moving your hands and shoulders now and then.
If you are choosing a new work laptop at the same time, the keyboard is one of the factors I cover in how to pick a laptop for engineering work, and an external keyboard and monitor are usually the best upgrade for any laptop used at a desk all day. For the reading side of desk work, see e-readers versus tablets for technical reading.
FAQ
Are mechanical keyboards better for typing than laptop keyboards?
For long sessions, usually yes. They offer more travel, a consistent feel and a choice of switch force. More importantly, an external keyboard lets you raise the laptop screen to eye level instead of hunching over it.
Which switch is best for typing: red, brown or blue?
There is no single best. Brown-type tactile switches are a common starting point for typists, red-type linear switches suit a light touch, and blue-type clicky switches are best kept for private offices.
Are mechanical keyboards too loud for an office?
Clicky switches are. Linear and tactile switches are quieter, and "silent" versions with dampers are quieter still. Adding O-rings or choosing a board with internal foam also reduces noise.
How much should I spend?
A good hot-swap, tenkeyless board with PBT keycaps typically costs less than a mid-range office chair. Spend on layout and switches first; premium metal cases and custom keycaps improve the feel but not your posture.
