Mouse Polling Rate Test Online
Estimate your mouse polling rate directly in the browser. Move your mouse to collect data points and calculate the approximate report rate in Hz. This browser-based test uses PointerEvent timing, which provides a reasonable estimate but not exact hardware-level measurement.

Frequently Asked Questions
What is mouse polling rate?
Polling rate (measured in Hz) is how often your mouse reports its position to the computer per second. Common values are 125Hz (8ms), 500Hz (2ms), and 1000Hz (1ms). Higher polling rates mean smoother cursor movement and lower input lag.
How accurate is this browser-based polling rate test?
Browser-based tests estimate polling rate from PointerEvent intervals. Results are influenced by display refresh rate, browser event coalescing, and system load. For precise measurement, dedicated hardware tools are recommended.
How can I change my mouse polling rate?
Most gaming mice allow polling rate adjustment through their manufacturer's software (e.g., Logitech G HUB, Razer Synapse, SteelSeries GG). Some mice have a physical switch on the bottom. Standard office mice typically operate at 125Hz and cannot be changed.
What is the best polling rate for gaming?
For competitive FPS games (CS2, Valorant, Overwatch 2), 1000 Hz is the standard recommendation. Some newer mice support 4000 Hz or even 8000 Hz, but the benefit beyond 1000 Hz is marginal for most players and may increase CPU usage. For casual gaming and office work, 500 Hz provides smooth responsiveness without unnecessary resource consumption.
Does polling rate affect wireless mice differently?
Yes. Higher polling rates on wireless mice consume more battery — a 1000 Hz mouse may last 40-60 hours, while at 125 Hz it could last 200+ hours. Wireless interference can also cause polling rate instability. Modern 2.4 GHz dongles (Logitech Lightspeed, Razer HyperSpeed) maintain stable 1000 Hz; Bluetooth mice typically max out at 125-250 Hz.
What's the difference between polling rate and DPI?
Polling rate (Hz) is how often the mouse reports its position to the computer. DPI (dots per inch) is how far the cursor moves per inch of physical mouse movement. They're independent — a 16,000 DPI mouse at 125 Hz reports less frequently than a 400 DPI mouse at 1000 Hz. For gaming, both should be optimized: moderate DPI (400-1600) with high polling rate (1000 Hz).
Why is my polling rate unstable or lower than expected?
Common causes: ① USB port bandwidth contention (try a different USB port, preferably USB 3.0); ② Wireless interference (move the dongle closer to the mouse); ③ Background processes consuming CPU cycles; ④ Mouse firmware issues (update via companion software); ⑤ USB hub limitations (avoid hubs for gaming mice). Run this test multiple times and check the peak vs average values for consistency.
Can browsers measure polling rates above 1000 Hz accurately?
Browsers have limitations for very high polling rates. Display refresh rate (typically 60 Hz) caps how often the browser can process pointer events. Browsers may also coalesce (merge) events to reduce overhead. For accurate measurement of 4000 Hz or 8000 Hz mice, use the WebHID API (available in Chrome/Edge) which bypasses the browser event coalescing. Our test supports WebHID when available.
