Click practice and measurement
Mouse Accuracy Test
Click 10 targets and see exactly how far each click landed from the centre, in CSS pixels — with your average, your best click and a retry whenever you want.
How to use
Running the click test
Test parameters
Targets, rounds and units
Fixed on purpose so your runs are comparable with each other.
- Targets: 10 per run, 30 CSS pixels in diameter, always fully inside the test area.
- Measurement: straight-line distance from the target centre to your click point, in CSS pixels, rounded to one decimal.
- One attempt per target: every click counts — including clicks that miss the circle — because the distance itself is the result.
- Pointers: mouse, trackpad, pen and touch all work; each click is a single pointer press.
Honest limits
What a click test on a web page is not
This is a click practice and measurement on your current screen. It reflects your hand–eye coordination together with your pointer speed, acceleration and polling settings — it is not a sensor test, not a DPI measurement, and not a hardware precision rating for your mouse. A web page cannot measure those.
Results also shift with display resolution, browser zoom and how warmed up you are. Use it to practice, to compare your own runs, and to settle “who clicks closer” — not to certify hardware.
Questions
Mouse accuracy test FAQ
What does this mouse accuracy test measure?
It measures how close each of your clicks lands to the centre of a target shown on this page. Every click's distance is given in CSS pixels, along with your average error, best click and completed targets. It is a click practice and measurement for this screen — not a rating of your mouse.
How does the test work?
Press Start. A target appears somewhere inside the test area; click it. Your click is measured as the straight-line distance from the target's centre, the next target appears immediately, and after 10 targets you get the full list plus your average. Try again as often as you like.
What counts as a good result?
There is no pass or fail. Smaller average distance means clicks landed closer to the centres on this run. Results vary with pointer speed settings, screen resolution, browser zoom, posture and practice, so compare against your own earlier runs rather than other people.
Does a bigger number mean my mouse is inaccurate?
No — this test measures where clicks land on the page, which is mostly about hand–eye coordination and pointer settings. It says nothing about your mouse's sensor, its DPI rating or its hardware precision; those cannot be measured from a web page.
Can I use it with a trackpad or a touchscreen?
Yes. The test accepts clicks from any pointer: mouse, trackpad, pen or touch. Keep in mind that finger taps cover a larger contact area than a mouse pointer tip, so touch results naturally differ from mouse results.
Why CSS pixels and what about zoom?
Distances are measured in CSS pixels — the unit the browser uses to lay out the page. If you change the browser zoom level, the same physical hand movement produces different CSS-pixel distances, so run comparisons at the same zoom level.
Is any click data recorded or sent?
No. Click positions are used for the on-the-spot calculation and display only. Nothing is stored beyond the current run and nothing is transmitted — this site runs no analytics; you can verify in the network panel.
