Mouse Polling Rate Test
Measures in the browser how many times per second your mouse reports its position. Check that your gaming mouse runs at the polling rate you set.
Move your mouse quickly in circles inside this box
Closest polling rate
+Hz
Measuring starts as soon as you move the mouse inside the test box.
Keep moving. The result appears after about 1 to 2 seconds of continuous movement.
The highlighted value is the standard polling rate closest to the measurement. Moving faster may raise it.
Measured above 1000Hz. Because browsers can only receive so many events, 2000, 4000 and 8000Hz are not told apart.
This came out below 125Hz. Try drawing faster circles in the box. If it stays low, the browser may be grouping events once per screen update.
This browser doesn't hand over grouped events separately, so the result may be lower than reality (near your screen's refresh rate). A recent Chrome, Edge or Firefox is recommended.
Touch and pen input are not measured. Please use a mouse.
Nothing is measured while the tab is hidden.

What is polling rate? Meaning and report interval by Hz
Polling rate (report rate) is how many times per second your mouse reports movement to the PC: every 8ms at 125Hz, 4ms at 250Hz, 2ms at 500Hz and 1ms at 1000Hz. It is not the same as DPI, which sets sensitivity.
How to test your polling rate
- Put the cursor in the boxMove the cursor into the test box above.
- Draw fast circlesMove the mouse in fast circles inside the box without stopping for at least 1 to 2 seconds.
- Read the highlighted valueIf the highlighted value differs from the rate you set, see 'Polling rate reading low? What to check' below.
Polling rate reading low? What to check
- The mouse's own softwarePolling rate is usually set in the maker's software or with a button under the mouse. Check it isn't set to 125Hz or 500Hz.
- Wireless connection typeBluetooth often has a lower polling rate than the mouse's own wireless receiver. Use the receiver for gaming.
- USB portPlug into a port on the back of the PC, not a USB hub or the monitor. Keep a wireless receiver close to the mouse.
- How you moveSlow movement gives the mouse less to report, so the number comes out low. Draw fast circles in the box for at least 1 to 2 seconds.
Cursor not matching your hand? Check mouse acceleration
Windows' 'Enhance pointer precision' sends the cursor farther the faster you move. Lutimize (our app) turns it off with one button, and you can undo it anytime.
How it measures, and its limits
It counts every mouse event in the box, including reports the browser grouped together (getCoalescedEvents), and uses ungrouped events (pointerrawupdate) where supported. Reports are counted per 0.1 second and the top 10% value is the result; it doesn't read the mouse's setting, so it has these limits.
- Browsers and Windows may merge or delay events; browsers that don't expose grouped reports show a value near the screen's refresh rate.
- For mice above 1000Hz (2000, 4000, 8000Hz) the browser may not receive every report, so they are shown only as '1000Hz or more'.
- A mouse only reports when it moves. Moving slowly gives a value below the real polling rate.
- pointerrawupdate exists only in Chrome, Edge and recent Firefox, and only works over HTTPS. Elsewhere, such as Safari, only grouped events are counted.
- Measurements are not sent to our server. Usage statistics record only that a test finished and which standard value range the result falls in.
Common questions
Is a higher polling rate always better?
At 1000Hz the mouse reports every 1 ms, so the cursor moves more finely than at 125Hz (8 ms). Going higher helps less and can cause stutter on some PCs and games, so drop to 1000Hz if it stutters.
Are DPI and polling rate different?
DPI is how many steps the mouse reports per inch (sensitivity); polling rate is how many times per second it reports. To match game sensitivity, use the eDPI calculator and the mouse sensitivity converter.
Why does my 8000Hz mouse only show "1000Hz or more"?
Browsers may not receive every report above 1000Hz, so 2000, 4000 and 8000Hz aren't told apart. Check the exact setting in the maker's software.
Can I test a wireless mouse?
Yes. Results can differ between the wireless receiver and Bluetooth, so test both.
Can I measure my mouse DPI?
This page does not measure DPI. Check DPI in the mouse maker's software or manual, and work out DPI multiplied by your game sensitivity with the eDPI calculator.
Can I measure a keyboard or gamepad polling rate?
This page only measures mice. To check that your keyboard keys register, use the keyboard test.
Are my results saved?
No. Measurements are calculated only inside this browser and are not added to the page address. Reloading starts a new measurement.
