eDPI Calculator

Enter your mouse DPI and in-game sensitivity to get your effective DPI (eDPI) and how far you move your mouse for a full 360-degree turn.

How to use the eDPI Calculator

  1. Enter your mouse DPI (from your mouse software).
  2. Enter your in-game sensitivity.
  3. Choose your game so the calculator uses the right turning speed.
  4. Read your eDPI, centimetres per 360° and inches per 360°. Change the numbers to compare setups.

Understanding your results

eDPI = DPI × in-game sensitivity. It lets you compare sensitivities across different DPI settings. cm/360 is the distance your mouse travels for a full turn: the lower it is, the faster your aim turns. It is the fairest way to compare sensitivity between players and between games.

What is eDPI?

eDPI stands for effective DPI. A mouse at 800 DPI with sensitivity 1.2 gives 800 × 1.2 = 960 eDPI; a mouse at 1600 DPI with sensitivity 0.6 gives the same 960. Two players with the same eDPI in the same game have the same turning speed, even though their settings look different.

eDPI = DPI × sensitivity

How cm/360 is calculated

Each game turns the camera a fixed number of degrees per mouse count (its "yaw"), multiplied by your sensitivity. A full turn takes 360 ÷ (yaw × sensitivity) counts; dividing by your DPI gives inches, and multiplying by 2.54 gives centimetres.

cm/360 = 360 ÷ (yaw × sens) ÷ DPI × 2.54

The calculator includes the yaw values for Counter-Strike 2 / CS:GO, Valorant, Overwatch 2, Apex Legends, Team Fortress 2 and modern Call of Duty. Switching games changes the cm/360 even when the eDPI is the same, which is why a converter is useful — try our mouse sensitivity converter.

Typical eDPI and cm/360 ranges

Tactical shooters are often played with a fairly low sensitivity — roughly 20 to 40 cm per 360 degrees is common among players who prefer to aim with the whole arm. Faster, more movement-heavy games are often played at higher sensitivity, around 10 to 25 cm/360. These are starting points, not rules: the best sensitivity is the one that lets you flick accurately and track smoothly without strain.

Tips to improve

  • Change only one setting at a time when testing a new sensitivity.
  • Give a new sensitivity at least a few sessions before judging it.
  • Use the aim test to compare setups with something measurable.

Frequently asked questions

No. It is only a measure of sensitivity. Lower sensitivity favours precision; higher favours speed and needs less desk space.

Games turn by different amounts per mouse count. Convert using cm/360 to keep the same feel.
