eDPI Calculator

Enter your mouse DPI and in-game sensitivity to get your effective DPI. Pick your game to also see cm/360 and a rough low-to-high scale, plus the matching sensitivity at other DPI settings.

What is eDPI?

eDPI, or effective DPI, is your mouse DPI multiplied by your in-game sensitivity. A player on 400 DPI with sensitivity 2 and a player on 800 DPI with sensitivity 1 both have an eDPI of 800, and in the same game they turn exactly the same distance for the same hand movement.

eDPI = DPI × in-game sensitivity

Why compare eDPI instead of sensitivity?

The sensitivity number alone means little, because it depends on the DPI behind it. Sensitivity 2 at 400 DPI is the same speed as 0.5 at 1600 DPI. eDPI removes the DPI from the comparison, so you can line up your setting with friends or with settings you see shared online, as long as everyone plays the same game.

eDPI vs cm/360

eDPI is handy inside one game, but every game turns the camera by a different angle per mouse count, so the same eDPI feels very different in CS2 and Valorant. cm/360 measures what actually matters for your arm: how many centimetres you move the mouse to turn a full circle. It is calculated from DPI, sensitivity and the game’s yaw value, and it is the same everywhere.

Use eDPI to compare setups in the same game.
Use cm/360 to compare between games or to move your aim to a new game.

How the scale works

The bands on the scale are rough, general guides. For CS2-style games with a 0.022 yaw they are: under 600 very low, 600–1000 low, 1000–1600 medium, 1600–2400 high, and above 2400 very high. For other games the bands are converted so they cover the same cm/360 range, which is why Valorant and Overwatch 2 show very different numbers. Many players fall outside these bands and aim just fine.

Changing DPI without changing feel

The table under the calculator keeps your eDPI the same and shows the sensitivity you would need at 400, 800, 1600 and 3200 DPI. That is useful when you get a new mouse or want a higher DPI for smoother desktop use without relearning your aim.

Switching games? The sensitivity converter turns your current setting into the matching value for CS2, Valorant, Apex Legends, Overwatch 2, Call of Duty and Team Fortress 2.

Frequently asked questions

What is a good eDPI?

There is no single good value. It depends on the game, your grip, your mouse pad size and personal taste. In CS2-style games many players sit somewhere in the low-to-medium bands shown above, but plenty play well outside them. Use the scale as a rough reference, not a target.

Can I compare eDPI between CS2 and Valorant?

Not directly. eDPI only multiplies DPI by the in-game number, and each game uses a different scale. A Valorant eDPI of about 280 feels like a CS2 eDPI of about 890. To compare across games, use cm/360 or the sensitivity converter.

Does a higher DPI make me aim better?

Not on its own. If you raise DPI and lower in-game sensitivity so the eDPI stays the same, your turn speed is unchanged. Higher DPI can give finer steps at low sensitivity, but most modern sensors track well at common settings like 400, 800 or 1600.

What should I pick if my game is not listed?

Choose “Other / no game”. You still get the eDPI and the DPI table, but no cm/360, because that needs the game’s yaw value. The bands then assume a CS2-style scale and may not fit your game.

Is eDPI the same as cm/360?

No, but they are linked. eDPI is a single number for comparing players in the same game. cm/360 is the actual distance you move the mouse for a full turn, and it works across games.
