This measures how often your browser receives mouse movement events (Hz). It is a useful proxy to spot obvious issues (e.g., stuck at ~125Hz), but it is not a lab-grade USB measurement.
Polling rate measures how often your mouse reports position updates, expressed in Hertz (Hz). A 1000Hz mouse sends 1000 updates per second, providing smoother cursor movement and lower latency—crucial for competitive gaming. This browser-based test measures your mouse's actual polling rate with no software installation, showing median, peak Hz, and stability.
Our polling rate tester measures the time interval between mouse movement events in your browser. When you move your mouse, each position update is timestamped with high-precision timers. By calculating the frequency of these updates, we determine your effective polling rate in Hz. We also show distribution patterns, median values, and stability scores. All processing happens locally—no mouse data is sent to servers.
This browser-based test accurately measures polling rates up to approximately 1000Hz for most scenarios. However, there are limitations: Browser event handling introduces some variance. Very high polling rates (2000Hz+) may not measure accurately. System load and compositor timing can affect readings. USB hubs or power saving may throttle rates. For lab-grade precision, hardware USB analyzers are more accurate.
125Hz is standard for basic mice, 500Hz is common for gaming, 1000Hz is high-performance. If expecting higher but seeing ~125Hz, check mouse software or USB power settings.
High stability means consistent polling intervals. Low stability with erratic readings may indicate USB issues, power saving throttling, or system interference.
The frequency distribution shows how consistent your polling is. A tight peak indicates stable polling; a wide spread suggests inconsistent intervals.

Methodology: Our testing methodology uses standard Web APIs (PointerEvent, performance.now()) supported by all modern browsers. Tests measure browser-level event frequency.
About: HardwareTest provides free, privacy-first hardware diagnostics. All tests run entirely in your browser with no data collection.
Disclaimer: This tool measures browser-level polling rates, which may differ from hardware-level rates. For precise measurements, manufacturer tools or USB analyzers may be needed.
