01What Is Key Repeat Rate?
Key repeat rate is the number of keydown events your keyboard sends per second while a key is held down, measured in Hz (events per second).

03How to Change Key Repeat Speed in Windows & Mac
Windows: Open Control Panel → Keyboard → Speed tab. Drag "Repeat delay" left (shorter) and "Repeat rate" right (faster). Click OK and test in the text box. Changes take effect immediately without rebooting.
04Why Repeat Delay Matters for Gamers
In many games, movement keys or menu navigation rely on the OS key-repeat mechanism. A long initial delay means your character hesitates before continuously moving. A low delay of 200 ms or less eliminates that pause.
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.
What is key repeat delay?
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.
What is the optimal repeat rate for gaming?
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.
How do I change key repeat speed in Windows?
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.
Does this test work on all keyboards?
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.
