About the eDPI Calculator

Hardware DPI and in-game sensitivity are just two factors of the same equation. eDPI = DPI × sensitivity collapses them into one number: 800 × 1.5 = 1200 is the same aim speed as 1600 × 0.75. When you change mouse DPI, divide sensitivity by the same factor to keep aim identical.

From eDPI to Physical Distance

The game's yaw constant converts mouse counts to degrees. In CS:GO (yaw 0.066), 800 DPI at 1.5 rotates the view 800 × 1.5 × 0.066 ≈ 79.2° per inch of mouse travel, so a full 360° turn needs 360 ÷ 79.2 ≈ 4.5 inches ≈ 11.5 cm — a fast, wrist-dominated sensitivity. Slower pros often sit near 30 cm/360.
