Understanding eDPI: The Ultimate Guide for Competitive Gamers

If you have ever wondered why two players with the same in-game sensitivity can have completely different aim experiences, the answer is eDPI. Understanding eDPI is one of the most fundamental concepts in competitive gaming, and it can make or break your performance.

What is eDPI?

eDPI stands for Effective Dots Per Inch. It is a single number that represents your true mouse sensitivity by combining your hardware DPI with your in-game sensitivity setting. The formula is simple:

For example, if your mouse is set to 800 DPI and your in-game sensitivity is 2.0 in CS2, your eDPI is 800 × 2.0 = 1600. This single number allows you to compare your sensitivity with other players regardless of their individual DPI and sensitivity settings.

Why eDPI Matters

Game-Specific eDPI Calculations

While the base formula is always DPI × Sensitivity, the meaning of the resulting eDPI differs between games because each engine interprets sensitivity differently. Here is how eDPI works in the most popular competitive titles:

CS2 eDPI

CS2 uses the Source 2 engine with a yaw value of 0.022. The eDPI formula is straightforward:

Valorant eDPI

Valorant uses Unreal Engine with a yaw of 0.07. Because Valorant sensitivity is on a different scale, the eDPI numbers are much lower than CS2:

Overwatch 2 eDPI

cm/360: The Universal Metric

While eDPI is useful for comparing within the same game, cm/360 (centimeters of mouse movement for a full 360-degree turn) is the universal metric that works across all games. It accounts for engine differences and gives you a physical measurement of your sensitivity.

Most professional FPS players fall in the 25-45 cm/360 range. Anything below 20 cm/360 is considered very high sensitivity, while above 60 cm/360 is very low.
