Keycap tools
Choose a keycap set by checking the keys your keyboard needs. The keycap picker helps compare common layouts with base and extension kit groups, so you can identify the coverage questions to settle before ordering.

How to use the keycap picker
Start with the keyboard's physical layout. The picker includes common full-size, tenkeyless, compact, and split-layout presets. Choose the nearest documented layout, then select the bottom-row or special option that matches the board you are checking. Use the keyboard maker's layout diagram if the percentage label leaves a size unclear.
Next, select a preset kit combination or tick the kit groups supplied with the set. The available groups include base, spacebar, ISO, numpad, and compact-layout extras. The known-set choices illustrate generic kit conventions; they are not a current stock list or a certification of a specific product sold under a familiar brand.
Run the check and read each requirement in the results. The picker marks modeled coverage gaps, suggests kit groups to inspect, and shows a simplified keyboard map. A missing group is a prompt to look at the corresponding extension kit, rather than proof that any product called an extras kit will solve the problem.
What to verify before buying
Compare every suggestion with the actual seller's kit diagram. Confirm the widths, quantities, spacebar options, and row shapes in the selected purchase. A render of a complete keyboard may use several kits, and a high total key count can still omit the one modifier your layout requires.
The picker cannot inspect the physical mount, check a stabilizer socket, or measure switch-housing clearance. Use the keycap compatibility guide for those checks. The kitting and coverage guide explains how to allocate the keys in a kit without counting the same cap twice.
Once coverage is settled, compare keycap profiles for shape and PBT vs ABS for material trade-offs. The tool runs in your browser without requiring an account. Its share button can copy the selected setup into a link, which is useful when comparing the same layout against several possible kit combinations.
