eDPI Calculator

eDPI stands for Effective Dots Per Inch. It is the only true way to compare mouse sensitivity between different players. Because your overall mouse speed is determined by both your hardware DPI (the setting on your mouse) and your software sensitivity (the setting in your game), comparing just one of these values is meaningless.

How to Calculate eDPI

The formula for eDPI is incredibly simple: DPI × In-Game Sensitivity = eDPI. For example, if you play with 800 DPI and an in-game sensitivity of 0.5, your eDPI is 400. If your friend plays with 400 DPI and a sensitivity of 1.0, their eDPI is also 400. Even though your settings look different, your physical mouse movement will result in the exact same crosshair movement on screen.

Finding the Perfect eDPI

There is no single 'perfect' eDPI, as it depends on your game, mousepad size, and aiming style (wrist vs. arm aiming). However, looking at professional players provides a good baseline. In tactical shooters like CS2 and Valorant, pros typically use a low eDPI (around 200-400 for Valorant, 600-1000 for CS2) to maximize precision. In fast-paced tracking games like Apex Legends or Overwatch, pros often use a slightly higher eDPI to quickly track targets and turn 180 degrees.
