Custom Keyboard Build Guide

Updated July 2026 · 10 min read

Building a custom keyboard is easier than it looks. You need four things: a kit (case + PCB + plate), switches, keycaps, and basic tools. This guide walks through a typical first build.

Step 1: Pick your kit

Start with a hot-swap kit so you can change switches later. Popular entry kits: Keychron Q series, KBDfans kits, or the Glorious GMMK Pro. Choose your layout (60%, 75%, TKL) before buying — you can't change it after.

Step 2: Choose switches

Buy a switch tester first if you're unsure. Read ourswitch guide for linear vs tactile vs clicky. Order enough switches for your layout plus 5–10 spares.

Step 3: Keycaps

PBT keycaps resist shine better than ABS. Check that your keycap set supports your layout (especially 75% and compact layouts need extra odd-sized keys).

Step 4: Assembly

1. Install stabilisers on larger keys (spacebar, shift, enter)
2. Mount the PCB into the case (follow kit instructions)
3. Press switches into the hot-swap sockets — they'll click in
4. Cap the switches with keycaps
5. Connect via USB and test every key before closing the case

Optional upgrades

• Lube switches — Reduces scratchiness; time-consuming but worth it
• Foam mods — Case foam and PE sheet improve sound
• Film switches — Reduces wobble on some switch housings
