Check Your Mouse Polling Rate in Hz
A free browser-based tool that measures how often your mouse reports its position to the computer. Analyzes the interval between pointer events to estimate the actual polling rate in Hz. Includes click latency measurement and a live graph — no installation needed.
How to Test Your Mouse Polling Rate
Move the cursor over the test area. Measurement starts immediately — no clicks needed. Move at a steady, fast pace for the most accurate reading.
Watch the large Hz reading, graph, and stats (average, min, max). The badge shows the closest common rate: 125, 250, 500, 1000 Hz or higher.
Click inside the test area to measure the mousedown-to-mouseup duration. The tool averages your last 10 clicks.

FAQ
What is mouse polling rate?
Polling rate is how often your mouse reports its position to the computer, measured in Hertz (Hz). A 1000 Hz mouse sends an update every 1 ms, while a 125 Hz mouse sends every 8 ms. Higher polling rates mean smoother cursor movement and lower input lag.
How accurate is a browser-based polling rate test?
Browsers coalesce mouse events into animation frames, which can lower the reported rate. Chromium-based browsers (Chrome, Edge, Brave, Opera) expose getCoalescedEvents(), which this tool uses to reconstruct the raw event stream. With coalesced events enabled, the test reliably distinguishes 125, 250, 500, 1000, and 2000+ Hz mice.
Why is my polling rate lower than expected?
A few factors affect the reading: browser event coalescing, display refresh rate, CPU load, and USB polling stability. For the most accurate result, close background tabs, use Chrome or Edge, and move the mouse at a constant fast speed.
What is a good polling rate for gaming?
Most modern gaming mice support 1000 Hz. Competitive FPS players prefer 1000 Hz or higher for the lowest input lag. For general productivity, 125–250 Hz is perfectly smooth. Premium wireless mice now offer 4000–8000 Hz, though only Chromium browsers can measure above 1000 Hz.
What does click latency measure here?
Click latency is the time between the button going down (pointerdown) and coming back up (pointerup). It reflects your switch activation plus finger speed, not total system latency. Typical values are 50–150 ms depending on how quickly you click.
