Guide

Use the Spacebar Clicker to measure real pressing speed

The Spacebar Clicker is a simple speed test for anyone who wants to measure how many times they can press the spacebar in a short run. Choose a preset time such as 5, 10, or 30 seconds, or enter a custom timer from 1 to 300 seconds. Once the test starts, every valid spacebar press increases your count and the CPS panel shows your clicks per second.

This tool is useful for quick reaction practice, keyboard testing, gaming warmups, or just comparing scores with friends. At the end of a timed run, the final CPS stays visible and the full result is added to your run history. Extra presses after the timer ends are ignored until you reset, so the result is easier to read and does not restart by accident.

For the most accurate result, keep your keyboard on a stable surface, use the same finger technique for each run, and compare scores using the same timer length.
