Mouse Polling Rate
Measure how many times per second your mouse reports its position.
Measure your mouse polling rate
Polling rate is how many times per second your mouse tells the computer where it is, measured in hertz (Hz). A 125 Hz mouse reports 125 times a second; a gaming mouse may run at 500 or 1000 Hz for smoother, lower-latency movement. To measure it, move the mouse continuously and fairly fast across the pad. The tool counts the position reports the browser delivers each second and shows the current, average, and peak rate. Keep moving steadily for a few seconds to let the average settle near your mouse's true rate. Note that browsers can cap or coalesce mouse events, so the reading is a close estimate rather than a lab measurement — a 1000 Hz mouse may read a little lower. Everything is measured locally and never uploaded.
Common questions
How do I measure my polling rate?
Move your mouse continuously and fairly quickly across the test pad for several seconds. The tool counts position reports per second and shows current, average, and peak Hz. Movement must be constant — the rate only registers while the mouse is moving.
Why is my reading lower than my mouse's rated Hz?
Browsers can throttle or batch (coalesce) pointer events, and slow movement produces fewer reports. The measurement is a close browser-level estimate; a 1000 Hz mouse often reads somewhat lower here even when working correctly.
What is a typical polling rate?
Standard mice usually run at 125 Hz. Gaming mice commonly offer 500 Hz or 1000 Hz, and some newer ones go higher. Higher rates give smoother, lower-latency cursor movement.
Why does the rate drop to zero?
The rate is measured from movement, so it falls to zero when the mouse is still. Keep moving to see a live reading; the average and peak values persist so you can read them after you stop.
Is my mouse data uploaded?
No. Movement events are counted in your browser only. Nothing about your mouse or its movement is stored or sent anywhere.
