Once you know your measured DPI, you can use the Tradeit eDPI Calculator or the Mouse Sensitivity Converter to fine-tune your setup across different games.
Mouse DPI Analyzer
Test your real mouse DPI by moving your mouse a measured distance. Use the result to compare your mouse settings, improve consistency, and calculate more accurate eDPI for your favorite games.
Test Settings
Move your physical mouse exactly this distance.
Use horizontal unless your desk space is limited.
Compare tested DPI with your mouse software setting.
Movement Test
Hold here to test
Hold your mouse button inside this ruler area, move the selected distance, then release to save the result.

What Is a Mouse DPI Analyzer?
A Mouse DPI Analyzer is a tool that estimates your real mouse DPI by comparing mouse movement data with a measured physical distance. It helps you check whether your mouse is close to the DPI value selected in your mouse software.
DPI means dots per inch. In gaming, it describes how much movement your mouse reports when you move it one inch on your desk or mousepad.
If your mouse is set to 800 DPI, moving it one inch should roughly produce 800 movement counts. In real use, the result may be slightly different because of sensor variance, surface quality, software settings, or acceleration.
How to Use This DPI Analyzer
1. Place a ruler or measuring tape next to your mouse.
2. Select a test distance, such as 5 inches or 10 cm.
3. Enter your expected DPI if you know it.
4. Click Start Test.
5. Move your mouse exactly the selected distance in a straight horizontal line.
6. Click Stop Test.
7. Repeat the test 3–5 times and use the average result.
How Mouse DPI Is Calculated
The analyzer uses your recorded mouse movement and divides it by the physical distance you moved your mouse.
Example: if you move your mouse 5 inches and the analyzer records 4,000 movement counts, your tested DPI is 800.
Why Your Measured DPI May Be Different
Your real DPI may not perfectly match the number selected in your mouse software. Small differences are normal and can happen because of sensor variance, mousepad surface, movement angle, software settings, or acceleration. Common reasons include:

Why DPI Matters for Gaming
DPI affects how much movement your mouse reports before your in-game sensitivity is applied.
For games like CS2, VALORANT, Apex Legends, Fortnite, Overwatch 2, and Rainbow Six Siege, DPI is only one part of your full sensitivity setup. The more useful number for comparing aim settings is usually eDPI:
Frequently Asked Questions
It gives an estimate. For better accuracy, use a longer test distance, move in a straight line, and average multiple tests.
Either works. The tool converts cm to inches internally because DPI means dots per inch.
Small differences are normal. Your hand movement, mousepad surface, test distance, and mouse sensor can all affect the result.
Not always. Higher DPI can make movement feel faster, but aim consistency depends on both DPI and in-game sensitivity.
No. This DPI analyzer is designed for desktop mice and requires real mouse movement input.
