How to Use the Spacebar and Click Speed Test
Select the duration
Try a short timed test or Free Counter mode. Custom timed tests run from 1 to 120 seconds.
Arm and begin
With no countdown, the first accepted press starts the clock and counts. With a countdown, wait for GO.
Review the results
Check average CPS, bursts and your timeline. Save the local results as CSV or JSON.
05 / KEYBOARD TESTING GUIDE
How to Measure Spacebar CPS Correctly
Spacebar CPS means the number of separate spacebar presses registered by the browser per second. The test counts a keydown once and ignores additional auto-repeat events caused by holding the key.
- Connect a physical keyboard and choose Spacebar mode.
- Click Arm Test to focus the testing surface.
- Use separate taps rather than holding Space continuously.
- Compare runs with the same duration and comfortable technique.
The result depends on your browser receiving events. It does not measure actuation force or mechanical switch quality.

How to Compare Mouse Click Speed and Mobile Tap Speed
Mouse, touchscreen and keyboard inputs behave differently. The tool records mouse clicks and touchscreen taps separately in its event feed, but groups them together in the click-mode total.
- Choose Click / Tap mode and use the large input surface.
- For a mouse, use the primary button. For a phone, tap with one finger.
- Keep the selected duration identical across comparisons.
- Use the Combined mode to see how many of each input type your browser registered.
Touchscreen taps are not proof of physical mouse clicks, and performance results can vary by device.

What Your CPS Test Results Mean
Measurements are descriptive, not grades. The most useful comparison is between your own tests with identical settings.
Average CPS
Average CPS equals accepted presses divided by test duration. A 10-second test with 50 accepted presses gives 5.00 CPS. Free mode uses the elapsed time until you finish.
Live CPS
The live score counts presses in the most recent one-second interval. It rises and falls during a session and may not match the final average.
Peak One-Second Burst
This is the highest number of accepted presses observed inside any rolling one-second window. It indicates a brief burst, not an overall performance rating.
Rhythm Stability
An approximate stability index describes variation between complete one-second buckets. Short tests may not have enough data for a meaningful stability reading.
Keyboard Auto-Repeat
Holding Space can generate repeated keydown events. This tester ignores events marked as auto-repeat and requires a release before another key press is accepted.
Timing and Hardware Limits
Timing uses performance.now(), but browsers and operating systems schedule and deliver input events. Results do not measure true hardware latency or switch debounce time.
08 / TROUBLESHOOTING
Spacebar or Click Test Not Working?
Spacebar scrolls the page
Press Arm Test and ensure the large dark test surface is focused. Keyboard input is intentionally captured only while the tester is active and focused.
Holding Space does not increase the score
That is expected. Held-key repeat is ignored so the counter reflects separate physical presses rather than automatic repeated keydown events.
Mobile taps do not register
Choose Click / Tap or Combined mode, then arm the test and tap inside the large surface. Some mobile browser gestures can interfere with input events.
Different browsers show different CPS
Input dispatch, focus, keyboard repeat configuration and background-tab scheduling can vary. Test in an active foreground tab for more consistent results.
09 / FREQUENTLY ASKED QUESTIONS
Spacebar and Click Speed Test FAQs
How do I test my spacebar speed online?
Choose Spacebar mode and a duration, press Arm Test, focus the large testing surface and repeatedly press and release Space. The page displays the accepted count, average CPS, live CPS and final score.
What does CPS mean?
CPS stands for clicks or presses per second. It is calculated by dividing the number of accepted events by elapsed time in seconds.
Does holding down Space count as many presses?
No. Keyboard auto-repeat is excluded, and the code requires a Space key release before accepting the next keydown event. Browser behaviour can still vary on unusual systems.
Can I take a 1-, 5-, 10-, 30- or 60-second test?
Yes. You can choose 1, 3, 5, 10, 15, 30 or 60 seconds, enter a custom 1–120-second duration, or select the untimed Free Counter mode.
How does the Combined test work?
Combined mode accepts Spacebar keydowns and primary mouse clicks or screen taps. The tool tracks the number of each input type as part of one timed session.
Does the test work on Android and iPhone?
Yes. Click / Tap mode supports normal touch pointer events in supported mobile browsers. Spacebar mode requires a hardware keyboard that sends standard keyboard events.
Can I measure true keyboard latency with this?
No. The tool measures browser-received presses over time. It cannot independently measure hardware-to-screen latency, switch actuation, or device polling rate.
Is there a leaderboard?
The page contains a private local history and personal bests, not a public leaderboard. Results are not verified against other players or submitted to a server by this widget.
Are my test results saved?
The most recent completed runs are saved in local browser storage where available. You can download a CSV or JSON file, or clear the local history. Private browsing and browser storage restrictions may prevent persistence.
Should I keep repeating the test to improve?
Short, occasional comparisons are sufficient. Take breaks, use a relaxed posture and stop if your hand or wrist becomes uncomfortable. Faster results are not a measure of overall gaming skill.
