eDPI Calculator: Valorant, CS2, and LoL Formulas Explained

eDPI stands for effective dots per inch, and you calculate it by multiplying your mouse DPI by your in game sensitivity setting: eDPI equals DPI times Sensitivity. It is the standard way competitive Valorant, CS2, and League of Legends players compare aim speed across different games and different DPI or sensitivity combinations, since a raw sensitivity number alone means nothing without knowing the DPI it was set at.

Why eDPI Matters More Than Raw Sensitivity

Two players can both run an in game sensitivity of 0.4, but if one uses 400 DPI and the other uses 1600 DPI, their mice move at completely different speeds on screen. eDPI strips out that variable. Multiplying DPI by sensitivity gives a single number that represents actual aim speed, so a Valorant player at 800 DPI and 0.4 sensitivity, 320 eDPI, can directly compare their feel to a player at 400 DPI and 0.8 sensitivity, since both equal 320 eDPI even though neither setting looks the same on paper.

The eDPI Formula, Plus cm/360

eDPI itself is simple: DPI multiplied by sensitivity. Most competitive players pair it with a second number, cm/360, which measures how many centimeters of physical mouse movement it takes to spin a full 360 degrees in game. That formula needs one more variable specific to each game, called the yaw value, the degrees of in game rotation the engine applies per mouse count. The formula is cm/360 equals (2.54 times 360) divided by (DPI times Sensitivity times Yaw).

Valorant eDPI Example

Valorant uses a fixed yaw value of 0.07. At 800 DPI and 0.4 sensitivity, eDPI is 800 times 0.4, which is 320. Plugging the same numbers into the cm/360 formula gives (2.54 times 360) divided by (800 times 0.4 times 0.07), which is 914.4 divided by 22.4, about 40.8 centimeters per 360 degree turn. Competitive Valorant players commonly land somewhere in the 200 to 320 eDPI range, though there is no single correct number, it comes down to what lets you track and flick consistently.

CS2 eDPI Example

CS2 carries over the same yaw value Counter-Strike has used for years, 0.022, which is why CS2 and Valorant eDPI numbers are not directly comparable at the same raw sensitivity despite using the same DPI times Sensitivity formula. At 800 DPI and 1.5 sensitivity, eDPI is 800 times 1.5, which is 1,200. The cm/360 works out to (2.54 times 360) divided by (800 times 1.5 times 0.022), which is 914.4 divided by 26.4, roughly 34.6 centimeters per 360. To convert a Valorant sensitivity into an equivalent CS2 sensitivity at the same DPI, multiply by 0.07 divided by 0.022, about 3.18.

League of Legends eDPI Example

League of Legends is not a mouse look shooter, so it has no yaw value and no cm/360 equivalent, the camera does not rotate the way an FPS camera does. eDPI still applies as DPI multiplied by in game sensitivity, and players use it mainly to describe raw mouse speed consistently when switching between mice or monitors rather than to fine tune flick accuracy. At 800 DPI and a 50 in game sensitivity setting, eDPI comes out to 800 times 50, which is 40,000. Because League's sensitivity slider uses a different numeric scale than an FPS, do not compare a League eDPI number directly to a Valorant or CS2 eDPI number, they are not on the same scale even though the formula looks identical.

Whatever eDPI you land on, dialing in a setup is part of getting serious about competitive play, and that same competitive scene is what people follow and bet on.
