About MouseTester

MouseTester is a free collection of tools for checking how a mouse or trackpad really behaves: click speed, double-click faults, polling rate, scroll wheel, sensor tracking, DPI and sensitivity conversion. It is for gamers, designers, office users and anyone wondering whether a mouse is worn out or just misconfigured.

• Mouse tools: CPS, double-click and button tests, polling rate, and wireless-versus-wired checks.
• Sensor and tracking: jitter, acceleration, lift-off and tracking tests.
• Clicks and scroll: scroll wheel, scroll direction and click-fault checks.
• Trackpad: gesture and trackpad tests plus settings guides.
• Calculators: DPI, eDPI and cross-game sensitivity conversion.

Browse everything on the all tools page.

Each test listens to the mouse and pointer events your browser already provides and does the maths on your device. Results depend on your browser, operating system and display, so treat them as practical measurements rather than lab-grade readings. Each tool page explains what it measures and where its limits are.

The site is written, built and checked by Unnikrishnan P, an independent developer and designer based in India with a background in banking and finance (B.Com, Banking and Finance, Christ University, Bengaluru; Diploma in Banking and Finance, IIBF; Certificate in Securities Markets, NISM). His skills include front-end development, design, Microsoft Excel and customer service, which is why the tools aim to be clear and quick to use.
