DPI (dots per inch) is a hardware setting that controls how many pixels the cursor moves per inch of physical mouse movement. Higher DPI means faster cursor movement at the same in-game sensitivity. Most competitive players use 400–1600 DPI.

eDPI (effective DPI) is DPI multiplied by in-game sensitivity. It provides a single comparable number across different DPI settings. For example, 800 DPI at sensitivity 2.0 gives 1600 eDPI — identical to 1600 DPI at sensitivity 1.0.

cm/360 is the physical distance (in centimeters) you must move your mouse to rotate the camera exactly 360 degrees. It is the universal unit for comparing aim feel across different games and hardware configurations. Most pro players use 20–50 cm/360.

Why does DPI change require a sensitivity adjustment?

When you double your DPI, your mouse sends twice as many counts per inch to the game engine. To keep the same camera speed, you must halve your in-game sensitivity. This tool calculates that adjustment automatically.

Yaw is the degrees of camera rotation per raw mouse count at sensitivity 1.0. Each game uses a different yaw multiplier (e.g., CS2 uses 0.022°/count, Valorant uses 0.07°/count). It is needed to convert sensitivity values into a universal cm/360 measurement.

Should I use 400 or 800 DPI?

Both are excellent choices for competitive play. 400 DPI provides a slight smoothness advantage on some sensors; 800 DPI gives finer micro-adjustments. The eDPI matters more than the DPI alone — pick whichever DPI your sensor performs best at, then set sensitivity to match your preferred eDPI.

Quick Reference — Common eDPI Ranges

Low Sensitivity

eDPI below 800 · 30–60 cm/360 · Preferred by precision rifle players

Medium Sensitivity

eDPI 800–1600 · 18–30 cm/360 · Most common pro player range

High Sensitivity

eDPI above 1600 · Below 18 cm/360 · Popular for tracking and flick shots

Summary

Convert mouse DPI, recalculate in-game sensitivity after a DPI change, and find your cm/360 and eDPI instantly.

How it works

Enter your current mouse DPI and in-game sensitivity.
Enter a game yaw value (degrees per count) or pick a preset.
Enter your new target DPI.
The tool calculates the equivalent sensitivity for the new DPI.
eDPI and cm/360 are displayed for both old and new settings.
Copy the new sensitivity to paste directly into your game.

Use cases
