DPI & Sensitivity Calculator

What is eDPI?

eDPI stands for Effective Dots Per Inch. It is a formula used to compare the true sensitivity of different players, regardless of what hardware DPI they are using. The formula is simply:

eDPI = DPI × In-Game Sensitivity

For example, a player with 400 DPI and 2.0 sensitivity has the exact same eDPI (800) as a player using 800 DPI and 1.0 sensitivity. Note that eDPI is game-specific; 800 eDPI in Valorant is completely different from 800 eDPI in CS2 because the game engines handle sensitivity scaling differently.

What is cm/360?

cm/360 is the physical distance your mouse needs to move on your mousepad to complete a full 360-degree turn in-game. It is the most accurate, universal way to measure and compare sensitivity across entirely different games.

• Low Sensitivity (50cm+): Popular in tactical shooters like CS2 and Valorant for precise micro-adjustments and crosshair placement.
• Medium Sensitivity (30cm - 50cm): A balanced middle ground, versatile for most games.
• High Sensitivity (<30cm): Preferred in fast-paced tracking games like Overwatch or Apex Legends where 180-degree turns happen constantly.

Why switch DPI?

Many modern gaming mice perform optimally at higher DPIs (like 1600 or 3200) due to reduced sensor latency, even if your eDPI remains the same. If you are playing at 400 DPI, switching to 1600 DPI and dividing your in-game sensitivity by 4 can slightly reduce input lag while keeping your crosshair movement feeling exactly the same.
