Mouse Tracking Speed Test

This mouse tracking speed test finds the fastest swipe your sensor can follow. Hold the left button inside the box and flick the mouse sideways as fast as possible. The peak speed is converted to inches per second using your DPI, and any direction flip at speed is flagged as a spin-out.

Find the limit safely

  1. 1. Enter your DPI

    The speed conversion needs it. Use the value set in your mouse software.

  2. 2. Clear the desk

    Fast swipes need room. Start from one edge of the pad and flick to the other.

  3. 3. Watch for coral flashes

    A flash means the sensor reported movement in the wrong direction mid-swipe: a spin-out.

How spin-out is detected

Direction flip at speed

A sensor that loses tracking often reports a sudden reverse. The tool flags flips above 20000 counts per second.

IPS and m/s

Both units so you can compare with the sensor's rated speed.

Speed trace

See how quickly your swipe ramped and where it peaked.

Repeat counter

Try several swipes; the fastest clean one is your usable limit.

Tracking speed terms

IPS
Inches per second, the standard rating for a sensor's maximum tracking speed. Modern sensors are rated 400 IPS and up.
Spin-out
The moment a sensor cannot keep up and reports garbage, usually a reverse or a freeze.
Malfunction speed
The manufacturer term for the speed at which spin-out begins.
Counts per second
Raw sensor reports per second; divide by DPI to get IPS.

Tracking speed questions

My peak is far below the sensor rating. Why?

Most people cannot swipe above 3 to 5 m/s by hand. Not reaching the rating is normal; reaching a spin-out is not.

Does DPI change the spin-out speed?

No. The physical speed limit is fixed; DPI only changes the counts.

Why does the test only measure horizontal movement?

Flicks are horizontal and the measurement is cleaner that way.

Fix spin-outs

Spin-out on fast flicks only

Normal on budget sensors. If it affects your games, choose a sensor rated 400 IPS or more.

Spin-out at low speed

Dirty lens or a bad surface. Clean and retest on a cloth pad.

Cursor freezes instead of reversing

That is also a tracking loss; the tool counts it as a swipe without a flip. Try a different pad.
