eDPI Calculator

Enter the DPI and sensitivity settings into the calculator to determine the eDPI. eDPI stands for effective dots per inch.

EDPI Formula

The following equation is used to calculate the effect dots per inch.

eDPI = DPI * S

  • Where eDPI is the effective dots per inch
  • DPI is the dots per inch of the screen
  • S is the sensitivity rating of the mouse


What is eDPI?

eDPI stand for effective dots per inch. This is term mostly used in gaming to describe the sensitivity setting a mouse is on.

eDPI vs Sensitivy

The reason eDPI is used instead of just sensitivity is because the true sensitivity depends on the size of the screen. For example, if someone were to set their sensitivity to the same setting but on two different monitors, one being half the size of the other, on the smaller screen the person would be able to move the curser faster with respect to what’s happening on the screen then the other monitor.


Let’s look at an example of how eDPI is calculated and can be used. Let’s assume we have two monitors, one with a dpi of 50 and one with a dpi of 100. Now lets assume you set you sensitivity to a setting of 1000. Calculating the eDPI of the monitors results in 50,000 and 100,000 respectively. This means that the smaller monitor has half of the eDPI of the larger monitor. This results the smaller monitor having a higher effective sensitivity.
