How to choose a mechanical keyboard

A mechanical keyboard is a set of trade-offs. This guide explains what each decision costs you, so you can evaluate any product rather than copying someone else list.

Switches

Linear switches move smoothly with no tactile bump. Tactile switches have a bump you can feel at the actuation point. Clicky switches add an audible click on top of the bump. Low-profile switches reduce travel and height.

The practical question is not which is better but which is appropriate for your environment. Clicky switches in a shared office are a social decision as much as a technical one.

Layout

Full size includes a number pad. Tenkeyless removes it. A 75 percent layout removes the number pad and tightens the function row and arrow keys into a compact footprint. A 65 percent layout also compresses the arrow keys into the main cluster.

If you enter numbers frequently, removing the number pad costs you real time. Decide this before you fall in love with a smaller board.

Connectivity

Wired is simplest and has no battery to manage. Bluetooth is convenient for switching between machines but can add latency. A 2.4 GHz dongle usually offers lower latency than Bluetooth while remaining wireless.

If you use more than one computer, check how many devices the board can pair with and how the switch works.

Hot swap and keycaps

Hot-swap sockets let you change switches without soldering, which is the single most useful upgrade path on a first mechanical keyboard. Keycap material and profile change feel and sound, and keycaps are replaceable, so treat them as a lower-stakes decision.

Software

Remapping and macro support vary widely. Some boards use open firmware with a browser-based configurator, others require a vendor application, and some expect an account. If you plan to remap keys, confirm the tool works on your operating system before buying.

Ergonomics

Keyboard height and angle affect wrist position. A board with a tall case may benefit from a wrist rest. None of this substitutes for an appropriate desk and chair setup, and a keyboard alone will not correct a poor workstation.
