Free Key Repeat Rate & Delay Tester — Keyboard Repeat Speed Online

Key repeat rate is how many times per second a held key fires repeat events after the initial delay. It is measured in Hz (events per second). Most keyboards default to 30 Hz; gaming keyboards can reach 50 Hz or higher.

Key repeat delay (also called repeat delay) is the time between the first keydown event and the second one when you hold a key. It is typically 200–1000 ms and controls how long you must hold a key before it starts repeating.

For gaming, a repeat delay of 200–250 ms and a repeat rate of 30–50 Hz is generally considered optimal. Lower delay means keys start repeating faster; higher Hz means faster repetition once started.

Open Control Panel → Keyboard → Speed tab. Drag the 'Repeat delay' slider left to shorten the delay and drag the 'Repeat rate' slider right to increase speed. Click OK and test in the text box provided.

Yes. The tester works on any USB, PS/2, Bluetooth, or wireless keyboard connected to a computer running a modern browser. It reads standard browser keydown events — no special drivers required.
