Mouse polling rate test
Measure the mouse movement event rate your browser can observe. A short test, an honest estimate.

Movement source—Coalesced samples used when available
Move for at least 0.2 seconds and collect 20 valid samples. A ten-second test with continuous movement gives a more useful estimate.

No relevant input captured yet.
This is a browser-observed polling/event-rate estimate, not a certified USB hardware polling rate. Browser scheduling, event coalescing, system load, movement and device settings can affect it.
Session average = intervals ÷ movement span. Pauses within the area lower the average. The median describes typical intervals from the latest 2,048 samples.
A trackpad can produce similar browser events. This site cannot identify your device or certify hardware condition.
01 / How to test
Start and move continuously in circles for 10 seconds.
- Use a physical mouse and keep this tab visible.
- Start the test, then move continuously inside the area for ten seconds.
- Read the average, sample count and movement span together. Repeat under similar conditions.
02 / If something seems off
If something seems off
- Try a direct USB connection or move the receiver closer.
- Check your mouse software’s report-rate setting.
- Close demanding applications and repeat. Use dedicated hardware tools if you need certified measurements.
Check your mouse polling rate in the browser
Polling rate is how often a mouse reports its position to the computer, written in hertz. 125 Hz, 500 Hz and 1000 Hz are common, and some gaming mice go higher. This test listens to the pointer events your browser receives while you move the mouse and estimates how many arrive each second.
That is a browser-observed event rate, not a certified USB measurement. Browsers can merge or delay pointer events, so the result is good for comparing settings and spotting problems, and it may read lower than the rate your mouse is set to.

01
Measure under consistent conditions
Follow the same routine each time for a fair comparison.
- 01
Keep the test visible
Leave this tab in the foreground and avoid switching windows while samples are collected.
- 02
Move for the full run
Make steady, broad circles rather than tiny twitches. The tool needs movement events to estimate a rate.
- 03
Compare repeated runs
Run it two or three times with the same mouse, port and settings. A stable pattern matters more than one peak number.
02
How to read the result
- 01Average rate
- The estimate in Hz across the whole run. For the cleanest figure, keep the tab in front and move in steady circles for the full ten seconds.
- 02Sample count
- How many movement events were counted. Very few samples mean the pointer barely moved or the page was throttled, so the average is less reliable.
- 03Median interval
- The typical gap between events. A steady median with an occasional long gap points to stalls rather than a mouse that is slow all the time.
- 04Movement span
- How much of the area you covered. Short, slow movements produce fewer events and a lower reading.
03
What a polling-rate reading can tell you
Use these patterns as clues, not automatic hardware verdicts.
The result changes widely
Movement, browser scheduling, system load or wireless power saving may affect the estimate.
A 4K or 8K mouse reads lower
Browser and display event delivery can limit what a webpage observes at very high rates.
04
Why the result may be lower than expected
- Moving too slowly or in very small movements, which gives the browser fewer events to count.
- Running the test in a background tab or on a busy computer.
- A wireless mouse in battery-saving mode or far from its receiver.
- A crowded USB hub instead of a direct port.
- A report-rate setting in the mouse software that is lower than you think.

Polling rate questions
01What polling rate should I use?
For everyday work, 500 to 1000 Hz is plenty. Higher rates mostly matter to competitive players on high-refresh-rate screens, and they can cost a little battery and processor time on some systems. Choose the highest setting that stays stable on your computer.
02Is a 1000 Hz polling rate good?
Yes. A 1000 Hz mouse reports roughly once per millisecond, which feels smooth and responsive for most games and desktop use. Rates above that mainly show up on very fast displays, and how much anyone notices varies.
03Why does the test show less than 1000 Hz?
The browser delivers pointer events at its own pace and can merge several mouse reports into one event. A lower figure here does not mean the mouse is set to a lower rate.
04How do I change my mouse polling rate?
Most gaming mice offer it in their companion software, and some use a button combination or a switch on the underside. The polling rate guide explains where to look and what to check afterwards.
