What is eDPI and How to Calculate It

eDPI (effective DPI) is the product of your in-game sensitivity multiplied by your mouse DPI. For example, 1.0 sensitivity at 400 DPI equals 400 eDPI. This unified measurement allows comparing sensitivity across different configurations. A player using 0.5 sensitivity at 800 DPI has the same eDPI (400) as 1.0 at 400 DPI.

Standardizing eDPI is important for consistency. Professional players maintain eDPI across all games, enabling muscle memory development. Most competitive CS2 players use 400-800 eDPI. Lower eDPI (200-400) suits long-distance engagement and precision; higher eDPI (800-1600) enables faster flick shots but sacrifices precision.

Calculating eDPI is simple: multiply sensitivity × DPI. If you play 1.5 sensitivity at 800 DPI, your eDPI is 1200. To match a player's eDPI from a different DPI setting, divide their eDPI by your DPI to get the required sensitivity. If you want 400 eDPI at 800 DPI, use 0.5 sensitivity.

Your monitor's DPI setting (separate from mouse DPI) should remain at the monitor's default setting (100% or 1.0x). Never adjust monitor DPI scaling as it introduces cursor acceleration inconsistencies. All adjustments should happen in mouse settings (hardware DPI) and in-game sensitivity.
