eDPI Calculator for Gaming Sensitivity
Calculate effective DPI from your mouse DPI and numeric in-game sensitivity, then reverse the formula when you change DPI. The result is instant, local, and most useful for comparing settings inside the same game.
eDPI calculator
Calculate DPI × Sensitivity
Enter the DPI configured in your mouse software and the sensitivity shown in your game. Choose percentage mode only when the game presents sensitivity as a percentage.
All calculations happen on this page. DPI and sensitivity values are not uploaded.
Find sensitivity from a target eDPI
Changing from 800 DPI to 1600 DPI? Enter the eDPI you want to keep and the new DPI to calculate the matching decimal sensitivity.
How to Use the eDPI Calculator
The calculator uses the standard eDPI formula without guessing your game, mouse model, or preferred sensitivity range.
Enter mouse DPI
Use the active DPI stage from your mouse software, not the maximum DPI printed on the box.
Enter game sensitivity
Copy the numeric sensitivity from the game and select decimal or percentage format.
Keep the game context
Save the game name, FOV, resolution, and input mode beside the result when comparing settings later.
What eDPI Means
eDPI means effective dots per inch. It combines hardware DPI and the game's numeric sensitivity into one convenient number.
For example, 800 DPI × 0.35 sensitivity equals 280 eDPI. Doubling DPI to 1600 while halving sensitivity to 0.175 keeps the same arithmetic eDPI.
The number is not a universal physical-distance measurement. Different games use different sensitivity scales, yaw values, field-of-view behavior, and input pipelines.
eDPI Calculation Examples
These examples show the arithmetic only. They are not recommended settings or pro-player benchmarks.
| DPI | Sensitivity | eDPI | Use |
|---|---|---|---|
| 800 | 0.35 | 280 | Decimal input example |
| 1600 | 0.175 | 280 | Same eDPI after a DPI change |
| 800 | 8% | 64 | Percentage input example |
Game-specific searches such as eDPI calculator CS2, Valorant eDPI calculator, and Fortnite eDPI calculator can use the same arithmetic, but the resulting numbers are not automatically interchangeable across those games.
Accuracy, Edge Cases, and Comparison Limits
eDPI is useful when its boundaries are clear. Keep these three limits with every result.
Same game first
Compare eDPI directly inside the same game and sensitivity scale. Cross-game conversion needs game-specific yaw or a measured cm/360 workflow.
Verify the active DPI
Mouse software may have several DPI stages. Confirm the active stage and disable accidental DPI switching before recording a baseline.
Not a performance score
Higher or lower eDPI is not automatically better. Comfort, control, target size, desk space, and practice goals all matter.
