Scroll Wheel Speed Test

Key Features

• Live RPM Estimator: Calculates physical wheel spin speed for infinite-scroll mice.
• Hardware Fault Detection: Automatically flags "Scroll Jumps" caused by dusty encoders.
• Distance Converter: Translates scrolling pixels into real-world meters.
• Target Dash Modes: Race to physical milestones like the 93m Statue of Liberty.
• Max Speed Radar: Tracks your absolute top scrolling speed in pixels per second.
• Zero Server Lag: Runs 100% locally in your browser for perfect accuracy.

How do I use it?

It's simple: Step 1: Select a Time Limit or a Distance Sprint mode. Step 2: Hover your mouse over the dark testing area. Step 3: Scroll your mouse wheel up or down as fast as you can to trigger the timer!

What is a Scroll Jump?

If dust gets inside your mouse's mechanical wheel encoder, the screen might jitter or scroll in the opposite direction. Our tool detects these rapid directional changes and logs them as Hardware Faults.

Is this tool free?

Yes, this hardware diagnostic tool is 100% Free. There are no limits on how many times you can test your hardware, and no software installation is required.

Supported Hardware

This tool is fully compatible with standard office mice and high-end gaming mice equipped with unlocked/infinite scroll wheels (such as the Logitech G502 or MX Master series).

Privacy & Security

Your privacy is absolute. Because this diagnostic runs entirely Client-Side (inside your browser), your hardware polling data and click speeds are never uploaded to our servers.
