Mouse Sensitivity Tester
Move inside the pad. We sum OS-reported movement deltas and estimate speed (px/s). Stay inside the box so the browser delivers consistent movement samples.

How to use
- Place the pointer inside the test pad.
- Move using a repeatable gesture (circle, straight line, figure-eight).
- Keep the same physical motion when you change DPI or in-game sensitivity so comparisons stay fair.
- Read total pointer travel and smoothed speed (px/s) as you move.
- Press Reset before each new comparison so stats do not mix runs.
FAQ
Is this an exact hardware DPI measurement?
No. It is a browser-level movement benchmark for relative sensitivity comparison.
How should I use this tool?
Use the same movement pattern across different settings to compare feel and speed consistently.
Introduction
Mouse Sensitivity Tester shows pointer travel and speed in the browser so you can compare sensitivity presets without extra desktop software. It is not a lab-grade hardware DPI readout.
Purpose
- Compare two DPI steps (e.g. 800 vs 1600) with the same hand motion.
- See whether a software or driver change alters on-screen pointer speed for the same physical swipe.
Key Features
- Live pointer travel (pixels) and smoothed speed (px/s) in the browser.
- Reset between presets so you do not mix runs.
- No install — instant sensitivity “feel” check.
Common Use Cases
- After changing Windows pointer speed, in-game sensitivity, or mouse DPI.
- Comparing two DPI steps with the same physical mouse motion.
Best Practices
- Use the same hand motion (distance and path) when comparing settings.
- Remember this reports browser-relative motion, not a certified DPI readout from the sensor.
Comparison metrics
| Metric | Notes |
|---|---|
| Total travel (px) | With identical physical motion, doubling DPI often lands near 2× pointer distance (browser rounding may add small variance). |
| Speed (px/s) | How “fast” the stack reports movement during a swipe — compare using similar gestures and time windows. |
Measurements reflect relative browser pointer motion, not a certified sensor DPI label.
