eDPI Calculator
Effective DPI = mouse DPI × in-game sensitivity. Enter your settings below.

Why eDPI matters
Two setups — 400 DPI at 0.8 sensitivity, and 800 DPI at 0.4 sensitivity — move your crosshair identically, both giving an eDPI of 320. Comparing raw DPI alone hides this; eDPI is the number players actually share when discussing settings, since it reflects real cursor speed regardless of how it's split between hardware DPI and software sensitivity.
Frequently asked questions
What is eDPI?
eDPI (effective DPI) is your mouse DPI multiplied by your in-game sensitivity setting. It gives a single comparable number for how far your cursor or crosshair moves per inch of physical mouse movement, regardless of the DPI/sensitivity split you use.
How do I calculate eDPI?
Multiply your mouse DPI by your in-game sensitivity: eDPI = DPI × sensitivity. For example, 800 DPI at 0.4 sensitivity gives an eDPI of 320.
What is a good eDPI for FPS games?
Competitive FPS players commonly use eDPI in the 200-400 range for a balance of precision and speed, though it varies a lot by game and personal preference — there’s no single correct number.
Why not just compare DPI directly?
Two players can have very different DPI and sensitivity values that produce the same actual cursor movement. eDPI normalises that so you can meaningfully compare settings between players or games.
