The spacebar speed test — also called a spacebar counter or spacebar clicker — measures how many times you can hit the spacebar in a set time. Choose 1, 5 or 10 seconds, smash the spacebar as fast as you can, and get your presses-per-second score to chase and share.
Start the spacebar testPick a duration and start pressing. The timer begins on your first spacebar press and counts every press until time runs out — held-down key auto-repeats are ignored, so only real presses count. Your live counter shows presses, current speed and time left. On mobile you can just tap the pad.
Most people manage around 6–8 presses per second on the 5-second test. Fast players push past 9, and short 1-second bursts can spike higher. Alternating fingers or using both thumbs on mobile can boost your rate with practice.
It counts how many times you can press the spacebar in a set time and reports your presses per second. It's also known as a spacebar counter or spacebar clicker.
No — auto-repeat from holding the key is ignored, so only genuine, separate presses are counted. That keeps scores fair.
Yes, it's free with a global leaderboard, and on touch devices you can tap the pad instead of using a keyboard.
