Calculate effective DPI (eDPI) for gaming mice. Note: cm/360° is game-engine dependent and not shown—it varies by game and engine. Use eDPI to compare raw mouse sensitivity across different setups.

Game sensitivity multiplier
eDPI (effective DPI) is a simple way to measure your real mouse sensitivity. It combines your mouse DPI and in-game sensitivity into one number: eDPI = DPI × sensitivity.
Players use an eDPI calculator because raw sensitivity numbers are not easy to compare. A sensitivity of 1.5 in one game does not automatically match 1.5 in another game. eDPI helps you compare settings more clearly within the same game or game sensitivity system.
For example, 800 DPI × 1.5 sensitivity = 1200 eDPI. That is the same effective sensitivity as:
Even though the DPI and sensitivity values are different, the combined result is the same.
To compare settings between different games, players usually rely on cm/360°, because different games use different sensitivity scales.
This is the standard formula used in any eDPI calculator.
DPI is your mouse hardware setting. Sensitivity is the in-game multiplier. Changing either one will change your eDPI, but the final feel can stay identical if the product stays the same.
This calculator uses a 0.022 conversion factor as an approximation. Exact cm/360° can vary by game engine and sensitivity model.
Usually lower effective sensitivity for precision and first-shot accuracy.
Often higher than tactical shooters to support tracking and faster turning.
Start with comfort, desk space, and consistency rather than chasing one “perfect” number.
Example setup: 800 DPI and 1.5 sensitivity
Multiply your mouse DPI by your in-game sensitivity. Example: 800 × 1.5 = 1200 eDPI.
There is no single best eDPI. Lower values usually favor precision, while higher values favor faster turning and flicks.
Not perfectly. Different games use different sensitivity systems, so cm/360° is the better cross-game comparison.
Many players use 400, 800, or 1600 DPI, then fine-tune their in-game sensitivity.
Not automatically. DPI changes the hardware input rate, but your final feel depends on the combination of DPI and in-game sensitivity.
cm/360° is the physical distance you move your mouse to complete one full 360-degree turn in-game.
Most players prefer lower effective sensitivity in Valorant than in faster arena shooters because precision matters more.
CS-style games usually reward lower effective sensitivity for stable crosshair placement and recoil control.
Fortnite settings vary more because players balance aim, editing, and building speed.
Use your current settings as a baseline, calculate eDPI, then match or fine-tune by cm/360° in the new game.
