Mouse Polling Rate Test (Hz Checker)
Move your mouse in circles over the pad. The checker reads every coalesced pointer event and turns the timing into a live polling rate in hertz.
Rate over time (Hz)
Checking whether your browser exposes every mouse report…
Polling rate is how many times per second your mouse tells the computer where it is. At 125 Hz that happens every 8 milliseconds. At 1000 Hz it happens every millisecond, and the newest gaming mice push 4000 or even 8000 Hz. A higher rate means each movement reaches the game sooner and the cursor path is built from more points, which is why fast flicks feel smoother on a well configured gaming mouse.
The problem is that the setting in your mouse software and the rate your computer actually receives are not always the same. A USB hub, a weak wireless signal, a power saving mode or the wrong profile can quietly cut it down. This polling rate checker measures what arrives, live, while you move the mouse.
How to check your mouse polling rate
- Move your pointer into the test area and start moving the mouse in fast, continuous circles.
- Keep moving for five to ten seconds. The current rate updates live and the graph shows how it changes over time.
- Watch the likely setting tile. Once enough samples are collected, it snaps the reading to the nearest standard rate such as 500 or 1000 Hz.
- Read the note under the graph. It tells you whether your browser exposes every report or only one per screen frame.
- Press Reset readings if you change a setting and want a clean measurement.
How the polling rate checker works
Counting every report
Browsers normally bundle pointer movement into one event per screen refresh to save work. Modern browsers also keep the individual reports that were merged, known as coalesced events. The checker counts every one of those reports and divides by the time the mouse was actually moving. Pauses are excluded, so stopping for a moment does not drag the average down.
Why you have to keep moving
A mouse only sends reports when something changes. Hold it still and it goes quiet, so a stationary mouse would read as close to zero hertz. Fast, smooth circles produce a steady stream of reports and the most reliable number.
Snapping to a standard rate
Measured values always wobble a little because of system scheduling and USB timing. A reading of 968 Hz is almost certainly a mouse set to 1000 Hz. The likely setting shows the nearest standard value, while the session average and peak show the raw numbers for anyone who wants them.
Wired, wireless and Bluetooth
Connection type changes what is possible. Wired USB mice and modern 2.4 GHz wireless receivers both reach 1000 Hz or more, and good wireless models are now as fast as cables. Bluetooth is different: it is designed for battery life rather than speed, and most Bluetooth mice report somewhere between 90 and 133 Hz regardless of what the mouse can do on its dedicated receiver. If your gaming mouse offers both, use the receiver for play and keep Bluetooth for travel or a second device.
Understanding your polling rate result
| Measured rate | Interval | Typical use |
|---|---|---|
| About 125 Hz | 8 ms | Office mice and default USB |
| About 500 Hz | 2 ms | Older gaming mice, battery saving modes |
| About 1000 Hz | 1 ms | Standard for gaming mice |
| 2000 to 8000 Hz | 0.5 to 0.125 ms | High end esports mice |
If the result sits near your monitor refresh rate, such as 60 or 144 Hz, your browser is probably not exposing coalesced events and the reading is capped by the screen. Try the latest Chrome, Edge or Firefox. You can confirm your refresh rate with the refresh rate test.
Why your polling rate might be lower than expected
- Wrong profile. Mouse software often stores polling rate per profile. Check the one that is active.
- USB hubs and front panel ports. Plug the mouse or its receiver directly into a rear motherboard port.
- Wireless interference. Keep the receiver within about a metre of the mouse, ideally on a short extension cable, and away from Wi-Fi routers.
- Battery saving. Many wireless mice drop their rate when the battery is low or when a power saving mode is on.
- CPU load at very high rates. 4000 and 8000 Hz need a strong processor. If readings jump around, 1000 or 2000 Hz may be the better choice.
Does a higher polling rate improve aim?
Going from 125 Hz to 1000 Hz is a clear improvement: input delay drops by up to 7 milliseconds and fast movements look noticeably smoother. The gains beyond 1000 Hz are real but small, most visible on high refresh monitors of 240 Hz and above. Polling rate also works alongside sensor sensitivity, so it is worth confirming your real counts per inch with the mouse DPI test.
After tuning the hardware, see whether you feel the difference. The reaction time test measures your response in milliseconds, and a few rounds of the CPS test show whether clicks feel crisper. If anything else about the mouse seems off, the mouse test checks every button and the scroll wheel.
Frequently asked questions
What polling rate should I use?
1000 Hz is the best choice for most players. It gives 1 ms reporting with little CPU cost. Higher rates help most on very high refresh monitors and fast processors.
Why does the reading jump around?
Small variation is normal because operating systems and USB controllers do not deliver reports with perfect timing. Keep moving the mouse in smooth circles and look at the average and the likely setting.
Why does my 1000 Hz mouse show 60 or 144 Hz?
Your browser is probably limiting movement events to one per screen frame. Update to a current version of Chrome, Edge or Firefox, which expose every individual report.
Does polling rate affect battery life?
Yes. Higher rates mean more radio transmissions, so a wireless mouse at 4000 Hz drains noticeably faster than at 1000 Hz.
Is polling rate the same as DPI?
No. Polling rate is how often the mouse reports. DPI is how much movement each inch of travel produces. Both affect how the mouse feels.
What polling rate should I use for gaming?
1000 Hz is a good default for most players. Higher rates such as 4000 or 8000 Hz can feel smoother on high refresh monitors but use more processor time.
Why does my 8000 Hz mouse show a lower number?
Browsers and operating systems may merge events, and a busy system can drop some. Try another USB port, close background apps and use a Chromium browser.
Does polling rate affect battery life?
Yes. Wireless mice use noticeably more power at higher polling rates.
Does the surface affect polling rate?
No, but a poor surface can cause tracking errors that look like uneven motion. Use a clean mouse pad.
