eDPI Calculator
The one number that lets you compare aim settings across different DPIs: eDPI (effective DPI). Enter your DPI and in-game sensitivity to get it instantly, plus the physical 360 distance.
eDPI = DPI × sensitivity. Two players, one at 400 DPI × 2 and another at 800 DPI × 1, both land on 800 eDPI — their mouse speed is identical. That's what makes eDPI the standard language for aim settings.
Pick your game from the dropdown to also see the corresponding cm/360 using that game's yaw constant.
How it works
eDPI multiplies your hardware resolution by the software multiplier. It collapses the two-variable problem into one comparable number:
eDPI = DPI × sensitivity
Raw sensitivity alone means nothing; 1.0 in CS2 is a completely different speed than 1.0 in Valorant. eDPI fixes that within a single game, and cm/360 fixes it across games.
Example
Switching from 400 DPI to 800 DPI on your mouse: halve your sensitivity to keep the same aim. 400 × 2.0 = 800 eDPI → 800 × 1.0 = 800 eDPI. The gauge above shows where you sit on the common scale.
The math behind it
eDPI = DPI × sens
Frequently Asked Questions
What is a "normal" eDPI?
Context-dependent per game. In CS2 400–1000 is typical, Valorant 200–450, Overwatch 2 (recognizing its 3.3× scale) often 3500–5500. Check the related game pages for ranges.
Does higher eDPI mean better aim?
No. It means faster aim. Precision players favor lower eDPI, fast-twitch players favor higher. What matters is constancy for your muscle memory.
Should I use eDPI or cm/360?
Use eDPI within one game (e.g. comparing your old and new DPI). Use cm/360 when moving between different games, since eDPI is not portable across yaw constants.
