What is eDPI and Why Does It Matter?

If you ask a pro player "What is your sensitivity?" and they answer "1.5", that information is entirely useless unless you also know their mouse DPI. This is where eDPI (Effective Dots Per Inch) becomes essential.

The eDPI Formula

eDPI = Mouse DPI × In-Game Sensitivity

Example A: Player uses 400 DPI and an in-game sens of 2.0. (400 × 2.0 = 800 eDPI)
Example B: Player uses 800 DPI and an in-game sens of 1.0. (800 × 1.0 = 800 eDPI)

Both of these players have the exact same true sensitivity. Their mouse will move across the screen at the exact same speed.

Why You Should Track Your eDPI

eDPI allows for a universal standard of comparison. When looking at pro settings databases, comparing the eDPI lets you instantly know if you are a "high sens" or "low sens" player relative to the best in the world.

Warning: Game Engines differ! An eDPI of 800 in CS2 is completely different from an eDPI of 800 in Valorant. eDPI is only useful for comparing players within the exact same game. To compare across different games, you must use a conversion tool or cm/360.
