DPI, eDPI and sensitivity explained

What is DPI?

DPI (dots per inch) is how many counts your mouse reports for every inch you move it. At 800 DPI, moving the mouse one inch sends 800 counts to the game. You set it in the mouse software or with a DPI button on the mouse.

What is eDPI?

eDPI is "effective DPI": your DPI multiplied by your in-game sensitivity. 800 DPI at 0.4 gives an eDPI of 320, exactly the same as 1600 DPI at 0.2. Because it is a single number, it is the easiest way to compare your settings with other players of the same game. Do not compare eDPI between different games, because each game turns the camera by a different amount.

What is cm/360°?

It is how far you move the mouse to turn a full circle. It is the fairest way to compare sensitivity between games, and it is the number our sensitivity converter uses.

Is there a good eDPI?

It depends on the game and on you. For example, TenZ plays Valorant at around 312 eDPI, while in CS2 s1mple uses about 1,236 and ZywOo about 760. Those numbers do not transfer between games, so check them with the calculator for the game you play. Low sensitivities favor precise aim and big arm movements. High sensitivities favor quick turns and wrist movement.

How to use the calculator

• Choose your game, then type your mouse DPI and your in-game sensitivity to see your eDPI and your cm/360°.
• To work backwards, open "Find sensitivity", enter the cm/360° you want and your DPI, and type the result into the game.
• Keep your DPI fixed (400 to 1600 is common) and change only the in-game sensitivity, so your numbers stay easy to compare.

Common questions

Does a higher DPI make me faster? Not by itself. What matters is the final cm/360°, which depends on DPI and in-game sensitivity together.

Should I turn off mouse acceleration? Yes. In Windows, turn off "Enhance pointer precision" and use raw input if the game offers it, so the same movement always gives the same result.
