eDPI, short for effective dots per inch, is the single number that describes how fast your crosshair actually moves, and it is what pros compare when they share settings. It is simply your mouse DPI multiplied by your in game sensitivity, which cancels out the fact that 400 DPI at sensitivity 2 feels the same as 800 DPI at sensitivity 1. This calculator gives you the exact eDPI figure the moment you type, and it also flags whether your value sits in the typical low, medium, or high range that most competitive players use. Lower eDPI favors precise flick control and wide arm movement, while higher eDPI suits smaller desks and faster spins. Everything is computed in your browser with no upload, so tweak your DPI and sensitivity freely and find the eDPI that fits your aim.
eDPI is effective DPI, computed as mouse DPI multiplied by your in game sensitivity, giving a single number that represents your true turn speed.
Two players can share a sensitivity value but move at very different speeds if their DPI differs, so eDPI lets you compare setups on equal terms.
Neither is objectively better; lower eDPI favors precise flicks with more arm movement while higher eDPI favors fast turns, and most competitive players sit in a mid range.
