What is eDPI in CS2?
eDPI means effective dots per inch. It is your mouse DPI multiplied by your in-game sensitivity. It gives one number for how fast your aim is, no matter how you split it between mouse and game.
Two players can have very different settings and the same eDPI. A player at 400 DPI and 2.0 sens has an eDPI of 800. So does a player at 800 DPI and 1.0 sens. In CS2 both turn exactly the same amount for the same hand movement.
How is eDPI calculated?
The formula is simple:
eDPI = DPI × sensitivity
At 800 DPI and 1.25 sensitivity, your eDPI is 800 × 1.25 = 1,000. The calculator does this as you type and also shows cm/360, which is often easier to picture.
How is cm/360 calculated?
cm/360 is how far you move your mouse, in centimeters, to turn a full circle in game. CS2 turns your view by 0.022 degrees per mouse count at sensitivity 1. That value is the default m_yaw in the game files.
cm/360 = (2.54 × 360) ÷ (DPI × sens × 0.022)
The 2.54 turns inches into centimeters, because DPI counts dots per inch. A lower eDPI means a bigger cm/360, so you move your arm more for each turn.
| DPI | Sensitivity | eDPI | cm/360 |
|---|---|---|---|
| 400 | 2.0 | 800 | 52.0 |
| 800 | 1.0 | 800 | 52.0 |
| 800 | 1.25 | 1,000 | 41.6 |
| 1600 | 0.5 | 800 | 52.0 |
| 1600 | 0.75 | 1,200 | 34.6 |
Worked example 1: a common setup
You use 800 DPI and 1.25 sensitivity, the CS2 default sensitivity.
- eDPI = 800 × 1.25 = 1,000.
- cm/360 = 914.4 ÷ (800 × 1.25 × 0.022) = 914.4 ÷ 22 = 41.6 cm.
That puts you in the "Medium" group of our own guide. It is also 170 eDPI above the pro median of 830 that we show on the bar.
Worked example 2: switching to a higher DPI
You play at 400 DPI and 2.0 sens, and buy a mouse that works best at 1600 DPI. You want the same aim speed.
- Your eDPI now is 400 × 2.0 = 800.
- To keep 800 eDPI at 1600 DPI, divide: 800 ÷ 1600 = 0.5.
- Set your CS2 sensitivity to 0.5.
Your cm/360 stays at 52.0 cm, so your aim feels the same. Only the mouse sends more counts per inch.
How does my eDPI compare with pros?
The gold line on the bar marks the median eDPI of CS2 pros, 830. That number comes from the prosettings.net CS2 settings guide, which says it is based on 940 pro players. We checked the page on 24 September 2026. The page was last modified on 3 May 2026.
A median means half the pros listed sit above it and half below. It is not a target. Many good players sit far from it on both sides.
What do low, medium and high mean here?
The colored groups are our own guide, not pro data. We picked round eDPI cut points to give a rough label.
| Group | eDPI | cm/360 at yaw 0.022 |
|---|---|---|
| Low | under 700 | more than about 59 cm |
| Medium | 700 to 1,199 | about 35 to 59 cm |
| High | 1,200 and up | less than about 35 cm |
Lower speeds make small, steady aim easier but need more arm movement. Higher speeds make quick turns easier but small aim needs a steadier hand. Pick what feels good and give it time.
Does eDPI cover scoped aim?
No. eDPI and cm/360 here describe hipfire, your normal aim without a scope. When you zoom in with a sniper or a scoped rifle, CS2 applies an extra scale on top called zoom_sensitivity_ratio. It runs from 0.01 to 3 and the game default is 1.
If scoped aim feels too fast or too slow, change that one setting and leave your main sensitivity alone. That way your eDPI and all your normal aim habits stay the same. You can add it to your config with the autoexec builder.
Should I change my eDPI?
Only if you have a clear reason, like you keep running out of mouse pad or you cannot hold your aim still on small targets. Change it in small steps, then play a few sessions before you judge it. Big jumps usually feel wrong for a while no matter which way you go.
When should you use this calculator?
Use it when you change mice, change DPI, or copy settings from a pro or a friend. eDPI lets you compare setups at a glance, and cm/360 tells you how much desk space you need.
If you come from another game, use the sensitivity converter first, then check the result here. You can also browse pro crosshairs or set up your config with the autoexec builder.
Settings sites and config downloads are a common place for scams. If a site asks you to log in with Steam to "copy a pro config", read how to spot fake Steam login pages first.
