DPI / eDPI Calculator
Calculate effective DPI and the distance needed for a full 360 degree turn.
About DPI / eDPI Calculator
eDPI makes sensitivity comparable between players using different DPI, but only cm/360 is comparable across different games, because each game applies its own yaw constant. Copying another player's in-game sensitivity without matching DPI produces a completely different feel, which is why eDPI rather than the in-game number is what gets shared.
Formula
DPI / eDPI
eDPI = DPI × in-game sensitivity; cm/360 = 360 ÷ (yaw × sensitivity) ÷ DPI × 2.54
- eDPI
- Effective sensitivity, comparable across different DPI settings
- cm/360
- Physical mouse movement for a full turn, the truly comparable measure
Worked example
With the default values below, DPI / eDPI Calculator returns Effective DPI of 360.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is DPI / eDPI calculated?
eDPI = DPI × in-game sensitivity; cm/360 = 360 ÷ (yaw × sensitivity) ÷ DPI × 2.54 eDPI makes sensitivity comparable between players using different DPI, but only cm/360 is comparable across different games, because each game applies its own yaw constant.
Why does DPI / eDPI matter?
Copying another player's in-game sensitivity without matching DPI produces a completely different feel, which is why eDPI rather than the in-game number is what gets shared.
What values do I need to enter?
This calculator takes 3 inputs: Mouse DPI, In-game sensitivity, Game yaw constant. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
