eDPI Calculator

What this does

So you play shooters and want to compare mouse sensitivities properly, your own across games or yours against a pro's, where raw DPI and in game sensitivity on their own do not tell the full story. This works out your eDPI. Enter your DPI and in game sensitivity, and it gives you the eDPI.

How to use it

1. Choose your game, then enter your mouse DPI, for example 800.
2. Enter your in game sensitivity as a decimal, for example 0.9.
3. Press Calculate to see your eDPI and turn distances.

How it works

eDPI, effective DPI, rolls your two sensitivity settings into one number so they can be compared directly. It is simply your mouse DPI multiplied by your in game sensitivity:

eDPI = DPI × in-game sensitivity

So 800 DPI at 0.9 sensitivity gives an eDPI of 720. Two players with the same eDPI move their crosshair the same amount for a given mouse movement, even if one uses high DPI with low sensitivity and the other does the reverse.

Comparing across games

One honest caveat: eDPI is a reliable way to compare sensitivities within the same game, but comparing across different games is rougher, because each game scales its sensitivity number differently. The same eDPI in two games does not always give the same real world turn, so the centimetres per 360 figure here is a close estimate rather than an exact match for every title. As a single number to track and tune your own sensitivity, though, eDPI is the standard players use.

As a rough guide, the tool labels a lower eDPI as low sensitivity and a higher one as high. Lower sensitivities, which need a bigger mouse sweep to turn, are popular for precise aiming, while higher ones trade some precision for quicker movement.
