How the EDPI Calculator works

This eDPI calculator multiplies your mouse DPI by your in-game sensitivity for Valorant, CS2, Apex Legends, Overwatch 2, Fortnite and more. Enter the DPI, the sensitivity and the game, and it gives your eDPI, how far the mouse travels for a full 360° turn, how that compares with professional players, and the sensitivity to type into any other game so the same hand movement turns you the same amount.

eDPI calculator: one number for how fast you aim

Aim in a shooter is muscle memory, trained on a physical distance. Change that distance and months of practice stop lining up. The trouble is that no game describes speed in centimetres. Each one shows a sensitivity number on its own scale, and your mouse adds its own DPI multiplier on top. eDPI and cm/360 turn all that into figures you can compare. You can check them against pros or carry them to a new game.

The formula

eDPI = mouse DPI × in-game sensitivity.

cm per 360° = 360 ÷ (yaw × eDPI) × 2.54.

Target sensitivity = your sensitivity × source yaw ÷ target yaw.

Yaw is the number of degrees an engine turns for each count the mouse reports at sensitivity 1. Source-engine games such as CS2, Apex Legends and Team Fortress 2, and Quake Champions, use 0.022°. Valorant uses 0.07°, Overwatch 2 and Call of Duty 0.0066°, Rainbow Six Siege 0.00223° at the default multiplier, and Halo Infinite 0.0225°. Rust uses 0.5 and Fortnite 0.5555 per unit, entered as a decimal, so type 8% as 0.08. The yaw ratio explains the famous rule of thumb that Valorant sensitivity is CS2 sensitivity divided by 3.18. That figure is just 0.07 ÷ 0.022.

Worked examples

The first example uses the defaults: 800 DPI at 0.5 in CS2. eDPI is 400, a full turn takes 103.9 cm of mouse travel, and the same feel in Valorant is 0.157. The CS2-equivalent eDPI is 400, which the calculator marks as low, slower than most pros. That suits a sweeping arm-driven style on a large pad.

The second example is a Valorant player on 800 DPI at 0.35. That is 280 eDPI. Multiplied by 0.07 ÷ 0.022 it becomes 891 CS2-equivalent eDPI, right in the professional range. It converts to 1.11 in CS2 at the same DPI, and a turn takes 46.7 cm.

How many centimetres per turn at common eDPI values

The table runs across the usual range, on the CS2 scale at 800 DPI. It gives the matching setting for three other games. Most professional CS2 players sit between 600 and 1,000 eDPI, which is roughly 40–70 cm per turn.

How to read the result

eDPI in your game is DPI × sensitivity on that game's own scale. Compare it only with other players of the same game.
Distance for a full 360° turn is the physical measure that works everywhere. Check it against your pad: at 50 cm per turn, a 180° flick needs 25 cm of clear space to one side.
Same feel in your target game is the value to type into it, keeping your DPI unchanged.
CS2-equivalent eDPI puts your setting on one common scale and labels it low, pro range, high or very high. The bands are 600 and 1,000, then 1,600.
At 400 / 800 / 1600 DPI gives the in-game values that keep the same eDPI if you change mouse DPI.

Where this is used

Sites that track professional settings list DPI, sensitivity and eDPI for thousands of players, because eDPI is the one figure that allows a fair comparison.

Tips and pitfalls

Match hip-fire only. Scoped and aim-down-sights sensitivities are scaled separately in most games, often with their own multiplier or a monitor-distance option. Convert the base value, then tune zoom by feel.
Field of view changes perceived speed. A wider FOV makes the same turn look slower on screen. Match cm/360 first, then adjust in small steps if the FOVs differ a lot. The FOV calculator converts horizontal and vertical values.
Turn off acceleration. Windows "Enhance pointer precision" and in-game acceleration make the distance depend on hand speed, and no converter can match that.
Use 800 or 1600 DPI. Modern sensors are accurate throughout their range. A higher DPI with a lower in-game value gives finer steps and smoother motion at the same eDPI.

The cm/360 calculator works backwards from a target distance to the settings. The monitor PPI calculator explains how screen resolution changes the desktop feel of the same DPI.

FAQ

What is eDPI?

Effective DPI: mouse DPI multiplied by in-game sensitivity. It gives one number for comparing settings between players in the same game regardless of their DPI. 800 DPI at 0.5 and 400 DPI at 1.0 are both 400 eDPI and feel the same.

What is a good eDPI for Valorant?

Most professionals use 200 to 320 eDPI, for example 800 DPI at 0.3 or 400 DPI at 0.65. That is roughly equivalent to 640 to 1,000 eDPI in CS2 because Valorant's yaw is about 3.18 times larger, so the numbers look small but the speed is normal.

How do I convert CS2 sensitivity to Valorant?

Divide the CS2 sensitivity by 3.18 and keep the same DPI. A CS2 sensitivity of 1.5 becomes 0.47 in Valorant. Going the other way, multiply by 3.18. The calculator does the same for every other pair of games using their engine yaw values.

Does DPI or sensitivity matter more?

Neither on its own; only the product matters for how fast you turn. Higher DPI with lower sensitivity gives smoother movement because the game receives more, smaller steps, so 800 or 1600 DPI with a lower in-game value is generally preferred over 400 with a high one.

Why does my converted sensitivity feel different?

Field of view. A wider FOV makes the same turn look slower on screen even though the hand movement is identical. Match the cm/360 first, then, if the game has a very different FOV, try the monitor-distance matching some converters offer, or adjust slightly by feel.
