How fast can you mash the spacebar? Select a mode and smash your way to the top.
The Spacebar Speed Test is a free online tool that measures how fast you can press the spacebar, reporting your speed in CPS (clicks per second). Choose from 5-second sprint, 10-second classic, or 30-second endurance modes. The test includes a live CPS counter, a per-second bar chart breakdown, and rankings from "Sleepy Sloth" to "Jitter Click Master."
Select your preferred time mode, then press Start (or hit spacebar). After a 3-second countdown, mash the spacebar as fast as possible. On mobile, tap the circular button instead. The test tracks every press with millisecond precision, displays a live sparkline of your CPS over time, and compares your first-half and second-half performance to show if you're speeding up or slowing down.
The average person clicks the spacebar at about 5-7 CPS. A score of 8-10 CPS is considered fast, 11-13 CPS is expert-level, and anything above 14 CPS is exceptional and typically requires advanced techniques like jitter clicking.
The fastest spacebar clickers can achieve 14-16 CPS using techniques like jitter clicking or butterfly clicking. Most people average around 6 CPS with normal tapping. Speed depends on finger dexterity, technique, and keyboard switch type.
Yes, mechanical keyboards with lighter actuation force (such as Cherry MX Speed Silver switches at 45g) allow faster repeated presses compared to membrane keyboards. The shorter travel distance and tactile feedback help improve CPS scores.
