Mouse Polling Rate Test

Test your mouse polling rate in Hz by moving your mouse across a tracking area. Instantly see your current, average, min, and max Hz with a live interval chart.

Move your mouse in this box to begin
Keep moving steadily for best results

Browser event timing has limited precision. Results may differ from dedicated desktop tools. Your effective in-browser polling rate depends on your browser, OS, display refresh rate, and system load.

How to use

  1. 1

    Open the test area

    Load the page and locate the large tracking area. No downloads or setup needed — the tool is ready immediately.

  2. 2

    Move your mouse

    Move your mouse steadily inside the tracking area. The tool begins recording event timestamps as soon as your cursor enters the box.

  3. 3

    Read your polling rate

    Watch the live Hz readout update in real time. Your current, average, minimum, and maximum polling rates are displayed alongside a stability score.

  4. 4

    Analyse the interval chart

    Check the bar chart below the stats for a visual breakdown of your last 50 event intervals. Green bars indicate consistent timing; red bars highlight outliers.

Frequently asked questions

What is mouse polling rate?
Polling rate is how often your mouse reports its position to the computer, measured in Hz. A 1000 Hz mouse sends its position 1,000 times per second, resulting in lower input lag than a 125 Hz mouse.
What polling rate should my mouse have?
Most gaming mice run at 1000 Hz. Budget mice default to 125 Hz. Some newer mice support 4000 Hz or 8000 Hz, though the difference above 1000 Hz is minimal for most users.
Why is my result lower than my mouse's rated polling rate?
Browsers cap event delivery — most browsers throttle mousemove events, so results may read lower than your hardware rate. This tool shows your effective in-browser rate, which is what web apps and games actually receive.
Does this tool work on laptops with trackpads?
Yes, but trackpads typically report at lower rates than dedicated mice. Results will reflect your trackpad's actual reporting speed.
Is the result accurate?
Browser-based polling tests are limited by the event loop and display refresh rate. For precise hardware-level measurement, use dedicated desktop software. This tool gives a useful approximation of your effective browser polling rate.

Find out your real mouse polling rate with this free browser-based Hz

tester. Simply move your mouse inside the test area and get an instant

live readout of your current polling rate in Hz, along with average,

minimum, and maximum values. A real-time bar chart visualises the last

50 event intervals so you can spot inconsistencies or throttling. A

stability score tells you what percentage of samples fall within 10% of

your average — useful for diagnosing jitter or comparing mice. Works

with any mouse on any OS. Everything runs in your browser — no

software to install and no data leaves your device.
