eDPI Calculator

eDPI (effective dots per inch) combines your mouse DPI and in-game sensitivity into one number, so you can compare settings with other players of the same game. Pick a game and you also get cm/360: how far the mouse travels for a full turn.

Quick examples
DPI

For Fortnite enter the percentage as a number: 7 for 7.0%.

      Formula

      eDPI = mouse DPI × in-game sensitivity
      Inches per 360° = 360 ÷ (eDPI × yaw)
      cm per 360° = inches per 360° × 2.54
      Yaw (degrees per count at sensitivity 1): CS2, CS:GO and Apex Legends 0.022; Valorant 0.07; Overwatch 2 0.0066; Fortnite 0.005555

      How to use it

      1. Enter your mouse DPI from its software.
      2. Enter your in-game sensitivity.
      3. Choose the game to get cm/360, or “Not listed” for eDPI alone.

      Worked examples

      CS2 at 800 DPI and sensitivity 1.0: 360 ÷ (800 × 0.022) = 20.45 in, or 51.95 cm per 360°

      Valorant at 1600 DPI and sensitivity 0.2: 40.82 cm per 360°

      eDPI only compares within one game

      Each game turns mouse counts into rotation differently, so an eDPI of 800 in CS2 and 800 in Valorant are completely different speeds. Within one game, 400 DPI at sensitivity 2 and 800 DPI at sensitivity 1 are the same 800 eDPI and feel the same.

      cm/360 compares across games

      The physical distance for a full turn means the same thing everywhere, which makes it the figure to match when you move to a new game. To convert a CS2 sensitivity to Valorant at the same DPI, divide by 3.18 (0.07 ÷ 0.022); to Overwatch 2, multiply by 3.33.

      Assumptions

      cm/360 assumes hip-fire at the default field of view, with mouse acceleration off and Windows pointer speed at its default so raw counts reach the game. Scoped and zoomed sensitivities use separate multipliers.

      Questions people ask

      What is my eDPI at 800 DPI and 0.5 sensitivity?

      800 × 0.5 = 400.

      What is the cm/360 for 800 eDPI in CS2?

      360 ÷ (800 × 0.022) = 20.45 inches, which is 51.95 cm.

      Is a lower eDPI better?

      Not inherently. Lower eDPI means larger arm movements and finer aim; higher means quicker turns with less desk space. Tactical-shooter players tend to prefer lower settings than players of faster-paced games.
