Mouse Polling Rate Calculator & Live Tester (Hz & Latency Tool)
Test your mouse polling rate live in the browser and calculate physical report intervals in milliseconds.
TL;DR: Mouse Polling Rate Calculator captures high-frequency pointer event timestamps in real time to calculate your mouse's actual instantaneous polling frequency (Hz), average rate, and report delay in milliseconds.

What is mouse polling rate and how do you test it online?
Direct Answer: Mouse polling rate is the frequency (measured in Hertz) at which a mouse reports its position to the computer. 1000Hz polls every 1.0ms, 4000Hz polls every 0.25ms, and 8000Hz polls every 0.125ms. You can test your live polling rate by moving your mouse rapidly across our in-browser event tracker.
In-Browser Execution: Calculated instantly inside your browser using client-side JavaScript with zero latency, downloads, or telemetry tracking.
How to Use the Mouse Polling Rate Calculator
- Click inside the designated tracking canvas area.
- Move your mouse continuously and rapidly in smooth circles.
- Watch the real-time instantaneous Hz gauge, maximum peak frequency, and average rate.
- Review your calculated hardware report interval in milliseconds.
Pro Tips & Best Practices
- 1000Hz (1.0ms) is the competitive esports gold standard; higher rates (4000Hz/8000Hz) require modern high-end CPUs to avoid frame drops.
- If your mouse fails to reach its advertised polling rate, plug it directly into a rear motherboard USB 3.0 port rather than a USB hub.
- Higher polling rates demand more CPU interrupts; monitor in-game CPU usage when running 4000Hz or 8000Hz.

Frequently Asked Questions
- 500Hz sends position data every 2.0ms, 1000Hz sends data every 1.0ms, and 8000Hz sends data every 0.125ms. Higher frequencies reduce tracking micro-stutter on high refresh rate displays (240Hz+).
- A mouse only reports updates when it is actively moving. Slow movements generate fewer positional deltas. Move your mouse rapidly in wide circles across the test area to saturate the sensor's maximum polling capacity.
- On older quad-core or 6-core CPUs, processing 8,000 hardware interrupts every second can overwhelm game main threads, causing micro-stutters. High-end CPUs (like Ryzen 7800X3D or i7-14700K) handle 8000Hz effortlessly.
- Yes. Running a wireless gaming mouse at 4000Hz or 8000Hz drains the battery 3 to 4 times faster than standard 1000Hz mode.
- No. The live listener processes pointer events entirely in local browser memory via JavaScript `PointerEvent` APIs with zero data transmission.
- Yes, modern Chromium browsers (Chrome, Edge) support high-resolution `getCoalescedEvents()` pointer APIs capable of capturing microsecond sub-millisecond mouse events.
- Higher DPI (800–1600+ DPI) generates more sensor counts per millimeter of movement, making it much easier to saturate the USB report buffer and reach true 4000Hz/8000Hz peak rates.
