- Switches define the feel: linear (smooth, quiet-ish) for gaming and fast typing, tactile (a felt bump) for typing feedback, clicky (loud) only if you and your neighbours can take it.
- Size is a lifestyle choice. Full-size for number-crunching, TKL for desk space, 75%/65% for a compact desk, 60% for minimalists who do not miss arrows.
- Hot-swappable + gasket mount + PBT keycaps are the upgrades you actually feel; RGB is the one you mostly do not.
A mechanical keyboard uses an individual spring-loaded switch under every key instead of a single rubber membrane. That is why it feels crisper, lasts longer (switches are typically rated for tens of millions of presses) and can be tuned to your taste. The flip side is choice overload: switches, sizes, mounting styles and keycaps all interact. This guide turns those into a short, ordered set of decisions. Because you may type on it for hours, it is also worth keeping ergonomics in mind — a keyboard positioned so your wrists stay straight and elbows near 90° reduces strain, as set out in OSHA computer-workstation guidance.
Step 1: Switches — the most important choice
The switch under each key determines how the board feels and sounds. There are three families:
- Linear — smooth top to bottom with no bump. Quiet-ish and consistent; favoured for gaming and by many fast typists. (Reds and similar.)
- Tactile — a noticeable bump as the key actuates, giving feedback without a loud click. A popular all-rounder for typing. (Browns and similar.)
- Clicky — a tactile bump plus an audible click. Satisfying to some, genuinely disruptive in shared spaces. (Blues and similar.)
Two numbers describe a switch: actuation force (grams — how hard you press, often 45–60 g) and actuation point/travel (how far down it registers). Lighter switches are faster but easier to mistrigger; heavier ones resist accidental presses. There is no "best" — only what suits your hands and your room. If you possibly can, try a switch tester or a friend's board before committing.
Step 2: Size and layout
Layout is mostly about desk space and whether you need a number pad. From largest to smallest:
| Layout | ~Keys | You keep | Best for |
|---|---|---|---|
| Full-size (100%) | 104 | Everything incl. numpad | Data entry, accounting, spreadsheets |
| Tenkeyless (TKL / 80%) | 87 | Function row + arrows, no numpad | Most people — the balanced default |
| 75% | ~84 | Function row + arrows, tight spacing | Compact desks wanting all keys |
| 65% | ~68 | Arrows, no function row | Small desks, travel |
| 60% | ~61 | Letters/numbers; arrows on a layer | Minimalists, mouse room for gaming |
Smaller boards free desk space and bring your mouse closer (nice for gaming), but move keys like arrows and Delete onto a "function layer" you trigger with a modifier. If you use arrows or the numpad constantly, do not go smaller than your habits allow.
Step 3: Build quality — what you actually feel
A few construction details separate a board that feels cheap from one that feels premium:
- Hot-swappable sockets let you change switches with no soldering — future-proofs the board and lets you tune the feel later. Highly recommended if you are unsure which switch you want.
- Mounting style (how the switch plate attaches to the case) shapes the typing feel and sound. Gasket-mounted boards are softer and quieter; tray-mounted are firmer and cheaper.
- Keycap material: PBT keycaps resist the greasy shine that develops on cheaper ABS caps over time, and feel slightly textured. A worthwhile upgrade you touch every minute.
- Stabilisers under big keys (space, Enter, Shift) determine whether those keys feel mushy or crisp; well-tuned stabs are a hallmark of a good board.
Step 4: Wired or wireless?
Modern wireless keyboards using a 2.4 GHz dongle have latency low enough that even competitive gamers use them; Bluetooth adds a touch more lag but lets you pair multiple devices. Go wired for the lowest possible latency, zero battery worry and the simplest setup; go wireless for a clean desk and easy switching between a laptop and a tablet. Many boards now offer all three modes (wired, 2.4 GHz, Bluetooth), which side-steps the decision.

What is over-hyped
Plenty of marketing chases the wrong things. RGB lighting is fun but changes nothing about how the board types — do not pay a big premium for it. "Gaming" branding and sky-high polling-rate claims rarely matter outside the top tier of competition. And a board you cannot comfortably try is a gamble: the feel is personal, so weight your money toward a good switch choice, hot-swap sockets and PBT caps over flashy extras.
