Mouse Test Online
Test every button on your mouse for free — left, right, middle, back, forward, and scroll wheel. Our online mouse tester shows real-time visual feedback on an interactive mouse diagram, plus measures your double-click speed and tracks cursor position.
Double Click Speed Test
Click twice quickly to measure your double-click interval
How to Use This Mouse Tester
Click any button inside the test area and watch the corresponding section on the mouse diagram light up. The click counters track how many times each button has been pressed. Scroll up and down to test the scroll wheel. Use the double-click area below the diagram to measure your click interval in milliseconds — helpful for checking if your mouse is double-clicking unintentionally.
Why Test Your Mouse?
A mouse test helps you catch problems that affect gaming performance and everyday productivity. Common issues include buttons that fail to register clicks, double-clicking from a single press (a sign of switch wear), a scroll wheel that skips or reverses direction, and side buttons that don't respond. If you're buying a new mouse or troubleshooting an existing one, this tool confirms every function works correctly in seconds.
This mouse tester works with any USB, wireless, Bluetooth, or laptop trackpad. It runs entirely in your browser on Windows, Mac, ChromeOS, and Linux — no download or account needed.
