How it works

  1. 01

    Press the spacebar to start. The counter listens for the space key specifically, so other keys do nothing.

  2. 02

    Holding the key down does not inflate your score. Operating system auto-repeat is filtered out, so only real presses count.

  3. 03

    The page never scrolls on space while the test is focused.

Common questions

Why does holding the spacebar not count?

Holding a key makes the operating system fire repeated keydown events. Those are filtered out, so only genuine presses register.

What is a good spacebar speed?

Around 6 to 8 presses per second with one finger. Alternating index fingers on the bar goes higher.

Can my keyboard limit my score?

Yes. Membrane keyboards need a fuller press to actuate than mechanical ones, and a worn switch can miss or duplicate presses.
