eDPI Calculator
Turn your mouse DPI and in-game sensitivity into one number that shows how fast you really aim.
The formula
eDPI = mouse DPI × in-game sensitivity
Your eDPI
800 × 0.4
- cm/360
- 40.8
- in/360
- 16.1
- Speed
- Medium
eDPI table for common setups
Example values for Valorant. Pick another game in the calculator above to see its cm/360.
| Valorant sens | eDPI at 400 DPI | eDPI at 800 DPI | eDPI at 1600 DPI | cm/360 at 800 DPI |
|---|---|---|---|---|
| 0.2 | 80 | 160 | 320 | 81.6 |
| 0.3 | 120 | 240 | 480 | 54.4 |

| 0.7 | 280 | 560 | 1120 | 23.3 |
| 0.8 | 320 | 640 | 1280 | 20.4 |
| 0.9 | 360 | 720 | 1440 | 18.1 |

What eDPI tells you
DPI is how many counts your mouse reports for each inch it moves. Sensitivity is how far the game turns you for each count. Neither number means much alone: 400 DPI at sensitivity 2 is exactly as fast as 800 DPI at sensitivity 1. eDPI multiplies the two, so it describes your real turn speed in one figure.
eDPI only compares players inside one game. To move your aim to another game, use the sens converter, which matches your 360° distance instead. If you are switching mouse DPI, the DPI calculator gives you the new sensitivity.
eDPI FAQ
What is eDPI?
eDPI means effective dots per inch. It is your mouse DPI multiplied by your in-game sensitivity. Two players with the same eDPI in the same game turn at exactly the same speed, even if one uses 400 DPI and the other 1600.
How do I calculate eDPI?
Multiply your mouse DPI by your in-game sensitivity. For example, 800 DPI with a Valorant sensitivity of 0.4 is 800 × 0.4 = 320 eDPI.
Can I compare eDPI between different games?
No. Each game has its own sensitivity scale, so an eDPI of 280 in Valorant and 280 in CS2 are very different speeds. To compare across games use cm/360, or convert your sensitivity with the sens converter.
Is higher or lower eDPI better?
Neither is better on its own. A lower eDPI needs bigger arm movements and makes small corrections easier. A higher eDPI lets you turn quickly with your wrist but is harder to control. Choose the one that lets you track and flick consistently.
Does DPI matter if my eDPI stays the same?
For turn speed, no. 400 DPI at sensitivity 2 and 800 DPI at sensitivity 1 give the same eDPI and the same 360° distance. A higher DPI can make very small movements slightly smoother, and it also speeds up your cursor in menus and on the desktop.
