Start the test, then keep moving
Small circles or a figure-eight pattern usually produces a more useful sample.
Keep the pointer inside this area. If it leaves, move it back and continue; you do not need to restart.

This is a browser-estimated event rate, not a direct reading of your mouse's USB report setting. Results can vary with your browser, operating system, CPU load, display refresh rate, driver, and movement pattern.
COMMON SETTINGS
What do 125 Hz, 500 Hz, 1000 Hz, and 8000 Hz mean?
A mouse polling rate is measured in hertz, or reports per second. Use these common settings to compare a device utility with the browser's estimated event rate.
| Setting | Approximate interval | How to read it |
|---|---|---|
| 125 Hz | 8 ms |
Baseline mode: about 125 reports per second. |
| 500 Hz | 2 ms |
A common middle setting with more frequent updates. |
| 1,000 Hz | 1 ms |
A common high setting for gaming and everyday use. |
| 2,000 Hz | 0.5 ms |
A higher-rate mode that can add event work. |
| 4,000 Hz | 0.25 ms |
A high mode where scheduling effects may be easier to notice. |
| 8,000 Hz | 0.125 ms |
Enthusiast mode; a browser estimate may be lower. |
These are reference settings, not promises about the number shown here. Browser polling delivery can be lower or more variable.
A SIMPLE WORKFLOW
How to test your mouse polling rate
The test answers one practical question: how frequently is this browser receiving movement events from your mouse? Match the conditions when comparing settings.
Choose a duration
Run a polling rate test for 10 seconds as a quick check, or choose 20 seconds for more samples and a clearer range.
Move continuously
Select Start Test and draw small circles or a figure eight inside the marked area. Keep the pointer moving.
Read and compare
Review the rate, average, peak, samples, and stability. Repeat with the same motion after changing a setting, port, driver, or wireless mode.
THE SHORT ANSWER
What is a polling rate test?
This browser check estimates how often a mouse sends movement updates that reach a computer. The result is shown in hertz, or Hz. A reading near 1,000 Hz means the page observed roughly one thousand usable pointer-event intervals per second during the sample.
Use the check to compare settings, see whether a high-rate mode appears active, or investigate an inconsistent mouse. It is most useful when the same duration and movement pattern are used for every run.
This page does not inspect firmware, USB packets, wireless radio traffic, or a driver queue. It measures delivered browser events with local timing, so treat the number as a practical diagnostic signal rather than a laboratory reading.
HOW THE ESTIMATE WORKS
A transparent browser-side measurement
The page listens for supported Pointer Events while you move a physical mouse. It measures the time between usable events with the browser's high-resolution clock and summarizes the polling sample locally.
Simplified estimate
Estimated Hz ≈ 1,000 ÷ average event interval in milliseconds
The polling reading uses valid intervals collected during the test. The first event, long pauses, and impractical timing values are excluded so a short pause does not dominate the summary.
Pointer Events
The tool prefers raw pointer updates when available and falls back to ordinary movement events. Browser support and scheduling affect the sample.
Robust summary
Average and peak summarize valid intervals. Stability reflects variation, so one unusually fast event does not define the result.
No movement upload
The movement stream is used for the current session only. No calculation API, account, or file upload is needed.
READ THE SIGNAL
How to interpret a mouse Hz test
A useful polling result is repeatable, not simply the largest number on screen. Read the metrics together and keep conditions consistent.
Estimated rate
This is the page's rounded summary of the current event stream. Compare it with the mouse setting as an estimate, not a direct USB confirmation.
Average and peak
Average shows typical valid behavior. Peak shows the fastest observed portion after basic filtering; it can reveal bursts but is not a guarantee.
Samples
Samples shows how much timing data supports the result. Little movement can produce too few intervals even when the setting is correct.
Stability
Stability summarizes interval variation. Pauses, event batching, CPU activity, wireless conditions, or changing speed can lower it.
WHEN COMPARING RESULTS
Keep the conditions matched
- Use the same browser window, duration, port, and movement pattern for both runs.
- Close heavy background applications when results change sharply.
- For wireless testing, use a charged battery and keep the mouse near its receiver.
- If a high setting feels no different, consider CPU load, display refresh, game support, and comfort.
ACCURACY & BOUNDARIES
Why can the result be lower than the mouse setting?
An advertised polling setting and a browser's observed event rate are related, but they are not identical measurements.
Event coalescing
Browsers and operating systems may combine or schedule updates differently. The page measures only events delivered to its active tab.
CPU and browser load
Heavy applications, background tabs, power saving, and a busy main thread can make timing less even. Reduce avoidable load and repeat.
Movement and focus
A stationary pointer produces no useful intervals. Pausing, leaving the area, or changing speed can lower sample quality.
Hardware and drivers
Ports, hubs, wireless interference, receiver placement, firmware, drivers, and device utilities can affect delivery. Check them before assuming a hardware fault.
For browser background, see MDN's Pointer Events and Fullscreen API references. They describe browser capabilities, not a direct hardware reading.
LOCAL BY DEFAULT
Your mouse movement stays in this page
The core measurement runs in the browser. It needs no account, download, movement upload, or server-side calculation request.
- Timing is calculated with browser JavaScript during the current test.
- Raw movement coordinates are not needed for the final result or intentionally stored after the test.
- Copy Result shares the summary you choose, not a movement trail.
- Analytics and advertising practices, if enabled, are described in the Privacy Policy.
COMMON QUESTIONS
Polling rate test FAQ
These answers cover common questions about comparing a mouse setting with a browser result.
How do I test my mouse polling rate?
Run a polling rate test by connecting the mouse, choosing 10 or 20 seconds, selecting Start Test, and keeping the pointer inside the area. Then review the estimated rate, average, peak, samples, and stability.
Do I need fullscreen for a polling rate test?
No. Fullscreen is optional. Focus Mode gives the card more space, but the normal page uses the same sampling logic.
Why is my mouse Hz test lower than the advertised setting?
The browser measures delivered pointer events, not the mouse's internal USB setting. Event coalescing, CPU load, scheduling, wireless conditions, drivers, and pauses can change the estimate.
Is 1000 Hz better than 500 Hz?
A higher setting shortens the interval between updates, but it is not automatically better. Compare repeatable results, CPU impact, game support, battery life, and comfort.
Can I run a mouse polling rate test on a phone or tablet?
It is intended for a physical mouse in a desktop-style browser. Touch events do not represent mouse polling rate; a mobile device may work only with a connected mouse exposed as a pointer.
Does this polling rate checker upload mouse movement?
No movement upload is needed. Timing runs in your browser, and the raw movement path is not intentionally sent to a server. See the Privacy Policy for other site data practices.
Why does my mouse polling rate change between runs?
Small changes are normal because timing, event batching, CPU activity, wireless conditions, and movement path can change. Use the same conditions and look for a repeatable range.
Can I test a keyboard or controller here?
No. This page measures mouse movement events. Keyboard and controller checks need different signals and separate tools.
