eDPI Calculator
eDPI (effective dots per inch) is the true measure of your mouse sensitivity in games. It combines your mouse hardware DPI with your in-game sensitivity into one number you can compare across different setups. This calculator also shows your cm/360 so you know exactly how far you need to move your mouse for a full turn.
The formulas:
- eDPI = Mouse DPI x In-Game Sensitivity
- cm/360 = (2.54 x 360) / (eDPI x Yaw Value)
What's a Yaw Value?
The yaw value determines how many degrees the camera rotates per mouse count. Most FPS games use 0.022 (including CS2, Valorant, and Overwatch 2). Apex Legends uses 0.022 as well. Some games differ, so check your specific game.
Pro Player eDPI Ranges
| Game | Typical Pro eDPI | cm/360 |
|---|---|---|
| CS2 | 600-1200 | 46-92 cm |
| Valorant | 200-400 | 28-56 cm |
| Overwatch 2 | 3000-6000 | 15-30 cm |
| Apex Legends | 800-1600 | 35-69 cm |
General rule: Lower eDPI (more mouse movement) gives you better precision for headshots, while higher eDPI lets you turn faster. Most competitive FPS players use a lower sensitivity than casual players.
