Mouse Polling Rate Test

Check your mouse polling rate in Hz. Run a 10-second movement check, then compare the average and browser-observed estimate.

Move to Measure

Select Start, then move in continuous circles for 10 seconds. Stay inside the area. The result freezes when the check ends.

What to do next

Measured Hz lower than expected?

  1. Complete a fresh 10-second check with continuous motion. An interrupted or sparsely sampled run is not a useful comparison.
  2. Repeat in the same browser with the same motion. Compare the average, not a single peak. Change only one setting per comparison.
  3. Confirm the polling setting in your mouse software and compare another browser. A low browser rate does not prove a hardware problem.

What is mouse polling rate?

Mouse polling rate, also called report rate, describes how often a mouse reports input to the computer. It is measured in hertz (Hz): 1000 Hz corresponds to 1000 reports per second. This online mouse Hz test estimates the rate of movement events delivered to your browser.

  • 125, 500 and 1000 Hz: what the numbers mean

    At a steady rate, 125 Hz corresponds to an 8 ms interval, 500 Hz to 2 ms and 1000 Hz to 1 ms. These are reporting intervals, not measurements of your full click-to-screen delay.

  • Can a browser test 4000 Hz or 8000 Hz?

    The tool includes common estimates from 125 to 8000 Hz, but that does not guarantee the browser can observe your mouse’s configured rate. Event delivery and system scheduling can limit the measurement, especially at high rates. Use the result for comparison, not hardware certification.

  • Why the average matters more than the peak

    Current Hz comes from the latest interval and can jump around. Average Hz uses the count and total duration of all valid intervals in this check; the estimated setting follows that average. A brief Peak spike is not proof that the mouse is running at that rate.

Understanding your mouse Hz test results

The estimate needs at least 30 valid intervals, one second of sampled interval time and an average of at least 90 Hz. Gaps over 250 ms are excluded. A 10-second observation with little movement remains insufficient.

How to test your mouse polling rate

  1. Select Start, then move the pointer inside the movement area to begin. Keep the page in the foreground.

  2. Move in continuous circles for 10 seconds. Leaving the area, switching tabs or pressing Escape interrupts the check.

  3. Wait for the observation to finish, then review Average Hz, valid intervals and sampled time together. The result stays frozen until you start again.

  4. Repeat with the same movement and computer settings. Ignore isolated peak spikes when comparing runs.

  5. If you change the polling rate in your mouse software, start a new check. Compare with the same browser and movement pattern.

FAQ

Frequently Asked Questions

Why is the measured Hz lower than my mouse setting?

Slow movement, browser event delivery, system load and device settings can affect the result. Repeat with continuous motion and compare the average. A low browser estimate does not establish that your mouse is failing to meet its configured hardware rate.

Why does the polling rate keep changing?

The time between delivered events is not perfectly even. Pauses and browser scheduling can change the current reading. Compare repeated averages rather than expecting every point on the chart to match.

Is polling rate the same as DPI?

No. Polling rate describes how often input is reported; DPI describes a mouse sensitivity setting related to physical movement. Use the Mouse DPI Test below to estimate pointer distance per inch.

Is this a mouse latency test?

No. This page measures intervals between browser movement events. It does not measure the delay from a physical click to a visible response, or certify an exact USB polling rate.
