Mouse DPI tester and sensitivity analyzer

Measure real mouse DPI from a controlled desk movement, compare repeated runs, and use the result for eDPI or game sensitivity tuning.

1 — Setup

Tip: Use a ruler on your desk. Mark start & end, then drag through the track area while pressing your mouse button. Each drag = one run. Up to 5 runs are averaged automatically.

2 — Track & Results

eDPI — Effective DPI

Formula: eDPI = Mouse DPI × In-game Sensitivity
eDPI lets you compare sensitivity fairly across different DPI settings and games.

Pro Range Comparison

Your eDPI is highlighted in the table below.

eDPI RangeLevelCommon for
200 – 400 Ultra Low Pro FPS (S1mple, sh1ro)
400 – 800 Low Competitive FPS / Valorant pros
800 – 1600 Medium General gaming, casual FPS
1600 – 3200High MOBA / RTS players
3200+ Very High Office, design, casual

Most pro FPS players use 200–800 eDPI for maximum precision.

New sensitivity — same muscle memory, different DPI

How It Works

The converter keeps your eDPI constant, so the same physical arm/wrist movement always moves your in-game view the same distance — even after you change DPI.

new_sens = (old_DPI × old_sens) / new_DPI

Example: 400 DPI at 2.0 sens → 800 DPI at 1.0 sens.
Both have eDPI = 800. Your aim feels identical.

When to use this:
• Switching to a new mouse with a different DPI
• Matching a pro player's feel at your DPI
• Cross-game consistency (same cm/360°)

Note: This keeps eDPI equal. In-game sens multipliers vary per game — verify the feel with the DPI Test tab after adjusting.

Mouse DPI tester guide

How to run an accurate mouse DPI test online

Use this DPI tester to check real mouse DPI, compare it with your configured DPI, and decide whether your mouse sensitivity or eDPI needs adjustment for gaming, office work, or high-resolution screens.

01 Set a known physical distance Use a ruler or measured mousepad distance. One inch works well, but a longer distance can make the DPI checker more stable.
02 Disable pointer acceleration first For the cleanest mouse DPI analyzer result, set Windows pointer speed to the default middle notch and turn off Enhance pointer precision.
03 Move straight and repeat the run Drag through the test area in one steady line, then repeat three or more times. Use the average if single runs vary.
04 Use the result for sensitivity and eDPI Combine measured DPI with in-game sensitivity to calculate eDPI, then confirm the setting with mouse accuracy, input latency, and CPS tests.

Quick DPI ranges: competitive FPS players often use 400-800 DPI, everyday work commonly feels comfortable around 800-1600 DPI, and 4K or multi-monitor setups may need 1600-2400 DPI. The best setting is the one you can repeat accurately.
If the same DPI feels different: read the same-DPI sensitivity troubleshooting guide after measuring. It explains how real DPI variance, Windows pointer speed, raw input, eDPI, polling rate, mousepad friction, and grip can change the feel.

DPI test FAQ

Common mouse DPI checker questions

How do I check my mouse DPI online?

Enter a known movement distance, start the DPI test, and move the mouse through the test area by that exact physical distance. The page estimates real DPI from browser pointer movement.

What DPI should I use for gaming?

Many FPS players use 400-800 DPI for precision, while MOBA, RTS, and high-resolution desktop users often prefer 800-2400 DPI. Use eDPI to compare complete sensitivity, not DPI alone.

Why is my tested DPI different from my mouse software?

Pointer acceleration, Windows pointer speed, mouse surface, sensor variance, and software-stepped DPI can all change the result. Disable acceleration, set Windows pointer speed to the middle notch, and repeat the test several times.

What is DPI vs CPI?

DPI and CPI are usually used for the same mouse sensitivity idea: how many cursor counts are reported for one inch of physical movement. CPI is technically more accurate, but DPI is the common search and product term.

Can I check DPI without a ruler?

You still need a known real-world distance. A ruler is best, but a credit card, ID card, or other object with a known width can work as the reference distance for the DPI checker.

Does this DPI test work on a laptop touchpad?

A touchpad can produce a number, but it does not have mouse DPI in the same useful sense because the operating system applies absolute positioning and acceleration. Use an external mouse for meaningful DPI results.
