What eDPI is
Players often compare mouse sensitivity, but in-game sensitivity alone means little: it depends on the mouse’s resolution. eDPI (effective dots per inch) combines both:
eDPI = mouse DPI × in-game sensitivity
Two players with 400 DPI and a sensitivity of 2, or 800 DPI and 1, both have an eDPI of 800 and turn the same amount for the same hand movement in the same game.
cm/360
eDPI is only comparable within one game, because each game turns by a different angle per mouse count, called the yaw. A measure that works across games is the distance the mouse travels for a full 360° turn:
cm/360 = 360 ÷ (DPI × sensitivity × yaw) × 2.54
| Game | Yaw (degrees per count at sensitivity 1) |
|---|---|
| Counter-Strike 2, Apex Legends | 0.022 |
| Valorant | 0.07 |
| Overwatch 2 | 0.0066 |
Converting between games
To keep the same feel, keep the same degrees per count: multiply your sensitivity by the yaw of the old game and divide by the yaw of the new one. A CS2 sensitivity is divided by about 3.18 for Valorant and multiplied by about 3.33 for Overwatch 2.
Example
At 800 DPI with a CS2 sensitivity of 1.2, eDPI is 960 and a full turn takes about 43 cm (17 in). The same feel is a sensitivity of about 0.377 in Valorant and 4.0 in Overwatch 2.
Choosing a sensitivity
- Tactical shooters reward low sensitivity: many professional CS2 players use an eDPI of roughly 700 to 1,100, and many Valorant pros roughly 200 to 400.
- Fast-paced games with lots of tracking and vertical movement often suit a higher sensitivity.
- A low sensitivity needs a large mouse pad and arm movement; a high one relies on the wrist.
- Change in small steps and give yourself a few days before judging.
DPI tips
Most modern sensors are accurate from 400 to 3,200 DPI. A higher DPI with a lower in-game sensitivity gives smoother movement in menus and at high resolutions, without changing the eDPI feel in the game itself.
