eDPI Calculator
Free eDPI Calculator — calculate your effective DPI for competitive gaming.
eDPI (effective DPI) lets you compare your true aiming speed across different DPI and sensitivity combinations — useful when switching mice, games, or comparing setups with other players.
Why Does eDPI Matter More Than Raw Sensitivity?
eDPI lets you compare your true aiming speed independent of your specific DPI and sensitivity settings. Two players with completely different DPI values can have identical eDPI — meaning their cursor moves the exact same real-world distance for the same physical mouse movement — which is why competitive players typically share eDPI instead of raw sensitivity numbers when comparing setups.
This matters practically when you change mice: if your new mouse has a different native DPI than your old one, keeping the same sensitivity NUMBER will actually change how your aim feels. Calculating eDPI first, then adjusting sensitivity to match your target eDPI on the new DPI, keeps your aim consistent through the switch.
FAQ's
What's a good eDPI for FPS games?
Competitive FPS players commonly use eDPI between 200-400, though personal preference and playstyle vary widely — slower, more precise players often use lower eDPI, and fast-flick players often use higher.
Why not just compare DPI directly?
DPI alone doesn't tell the full story — a 400 DPI mouse at 2.0 sensitivity can feel identical to an 800 DPI mouse at 1.0 sensitivity. eDPI (DPI × sensitivity) accounts for both.
Should I match a pro player's eDPI exactly?
It's a reasonable starting point, but the best sensitivity is ultimately whatever lets you aim most accurately and comfortably for your own playstyle and mouse grip.
Does eDPI transfer perfectly between games?
Not perfectly — eDPI is a useful comparison metric, but true 1:1 consistency across games requires converting by cm/360, since games calculate sensitivity differently. See our Sensitivity Converter for that.
