“Effective Dots per Inch”, or eDPI, describes the apparent sensitivity of your mouse mouse movement, irrespective of hardware or software.
It’s useful for accurately sharing settings with your friends or for trying out settings used by the pros, especially when you’re using a mouse with different DPI settings. In other words, you can feel how others are experiencing the game without having to replicate their exact setup.
eDPI is calculated using an extremely simple formula. For CS2 (formerly CS:GO), all we need is the DPI of the mouse, and the value of the in-game sensitivity.
That simple formula is as follows:
eDPI = DPI x In-game Sensitivity
If you play CS2 with your mouse on 800 DPI and your in-game sensitivity is 1.25, your eDPI is 1000 (800 x 0.8). Online sources suggest that the most commonly used setup among pro players is 800 eDPI.
CS2 uses a decimal system for in-game sensitivity. To find this, go into your settings menu using the cog symbol at the top left of the main menu. Under ‘KEYBOARD / MOUSE’ you should see an option for ‘Mouse Sensitivity’. Make a note of this number.
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 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.
