EDPI Calculator — Mouse Sensitivity Converter (eDPI & cm/360)

The Formula

Effective DPI (eDPI) standardizes mouse sensitivity across different DPI settings by multiplying your mouse DPI by your in-game sensitivity. For cross-game conversion, each game has a unique multiplier that accounts for differences in how the game engine interprets sensitivity values.

How to Use This Calculator

1. 1

   Enter your mouse DPI (usually found in your mouse software or settings).

2. 2

   Enter your in-game sensitivity from your current game.

3. 3

   Select which game you are currently playing.

4. 4

   Optionally select a target game to convert your sensitivity.

5. 5

   Use the eDPI value to match sensitivity across different games and settings.

eDPI = DPI × Sensitivity standardizes cursor speed. Different DPI/sensitivity combinations can produce the same eDPI.

Understanding the Concept

eDPI (Effective Dots Per Inch) is the universal standard for comparing mouse sensitivity across different games and DPI settings. By multiplying your mouse DPI by your in-game sensitivity, you get a single number that represents your true cursor speed. Two players with the same eDPI will have the same muscle memory, even if one uses 400 DPI at 4 sensitivity (eDPI = 1600) and the other uses 800 DPI at 2 sensitivity (eDPI = 1600). Cross-game conversion adjusts for the different sensitivity scales each game uses. For example, Valorant uses a more sensitive scale than CS:GO, so a Valorant sensitivity of 0.314 feels equivalent to a CS:GO sensitivity of 1.0. Practical example: if you play CS:GO at 800 DPI with 2.5 sensitivity, your eDPI is 800 × 2.5 = 2000. To convert to Valorant: 2.5 × 1 / 0.314 = 7.96 sensitivity — but that seems very high because Valorant's scale is different. Actually the correct conversion: Valorant sensitivity = (CS:GO sens × CS:GO multiplier) / Valorant multiplier = (2.5 × 1) / 0.314 = 0.785. So your Valorant equivalent is 800 DPI at 0.785 sensitivity. Edge cases: raw input vs. mouse acceleration — this calculator assumes raw input with no acceleration. If Windows pointer speed is not at the default (6/11), or if "Enhance pointer precision" is enabled, the effective sensitivity changes unpredictably. For games with separate ADS (aim down sights) sensitivity multipliers, the eDPI changes when scoped. For tracking-heavy games like Overwatch and Apex, a slightly lower eDPI (1200-1600) is common for precise tracking, while for flick-heavy games like Valorant and CS:GO, a higher eDPI (1600-2400) is more typical. Pro players generally range from 400 eDPI (very low, arm aimers) to 3200 eDPI (high, wrist aimers).
