Keyboard Test

Check that every key works — spot dead keys, stuck keys and ghosting, right in your browser.

Press any key to check that your keyboard works. Each key lights up when held and stays colored once tested, so you can see full-keyboard coverage and spot dead or stuck keys.

Tip: hold several keys at once to test N-key rollover (anti-ghosting) — the number of keys registering at the same time.

About This Content

Free online keyboard test to check your keyboard in seconds. Press any key and it lights up on an on-screen keyboard; tested keys stay highlighted so you can see full-keyboard coverage at a glance and catch dead or stuck keys. Hold several keys at once to test N-key rollover (anti-ghosting) — how many keys register simultaneously. Everything runs right in the browser — no download, no install. Great for checking a new mechanical keyboard or troubleshooting one that's acting up.
