eDPI stands for “Effective Dots per Inch”. Basically, eDPI describes the apparent sensitivity of your mouse mouse movement, irrespective of hardware or software. It’s useful for two main reasons:
eDPI is surprisingly easy to calculate - but can be a bit confusing as different games define sensitivity in different ways. This is explained further down with some examples. But the core concept, i.e. the following formula can be applied to any game.
That simple formula is:
eDPI = DPI x In-game Sensitivity
If you play Valorant with your mouse on 800 DPI and your in-game sensitivity is 0.27, your eDPI is 216 (800 x 0.27). This applies to any game that uses a whole number or decimal based sensitivity system such as Valorant or Counter Strike 2.
Other games, such as Fortnite, use a percentage based sensitivity. For example, 800 DPI with an in-game sensitivity of 10% results in an eDPI of 80 (800 x 0.1).
Firstly, you need to check which type of sensitivity is used in the game you're playing.
Valorant and Counter Strike 2 both use a whole number or decimal system, whereas games like Fortnite are percent based. The easiest place to check this is within the game's settings where you should see either a whole number, decimal, or percent based sensitivity.
You’ll then need to find the DPI of your mouse. Most gaming mice use a piece of software that lets you adjust the DPI, such as iCUE for CORSAIR. Cheaper, non-gaming mice will either have a fixed DPI (found in the documentation of the mouse in question), or often a button on the underside that cycles through a number of fixed settings.
Enter your in-game sensitivity and mouse DPI into the calculator below and it will automatically calculate your eDPI.
What is DPI?
DPI stands for “Dots Per-Inch”. The DPI number is effectively tied to the resolution that your mouse's sensor detects.
High and low DPI both have their strengths and weaknesses, and you might want to switch between the two depending on what you’re actively playing.

Can you compare eDPI settings between games?
No. eDPI is calculated by multiplying your mouse DPI with in-game sensitivity, which will vary for each game. However, you can use it backwards to make different games feel more consistent when compared to each other.
eDPI is best used when comparing your settings with friends or pros in the same game.
