eDPI is DPI and sensitivity rolled into one number
Your mouse DPI and the game's sensitivity slider both scale your aim, so neither one tells the whole story on its own. eDPI multiplies them together into a single figure you can compare against any other player, whatever hardware they run.
400 DPI at 2.0 sens and 800 DPI at 1.0 sens both give an eDPI of 800 — identical aim speed from different settings. That is the whole point: two setups with the same eDPI turn the exact same amount.
eDPI in real desk distance
The distance to spin a full circle is 914.4 (that is 360 × 2.54 cm/inch) divided by eDPI. It is the one number that does not depend on resolution or frame rate.
| eDPI | cm/360 | Feel |
|---|---|---|
| 400 | 2.29 cm | Very slow, maximum precision |
| 600 | 1.52 cm | Low, typical for CS2 |
| 800 | 1.14 cm | Balanced, common Valorant range |
| 1200 | 0.76 cm | High, quick turns |
| 1600 | 0.57 cm | Very high, twitchy |
Overwatch does not fit this scale — its slider runs 1 to 20 rather than around 1, so multiply DPI by that raw number if you want a comparable eDPI.
What to know before you copy a pro's numbers
- Precision games run low. Most CS2 pros sit around 600 to 800 eDPI. It feels slow at first, but the large, controlled arm movements build the muscle memory that wins one-shot duels.
- A good starting point is 800 eDPI. For CS2, Valorant or Overwatch, 800 to 1000 is a safe middle. Give any change two to four weeks before judging it — your aim adapts slowly.
- Match your mousepad, not just the pro. A low eDPI needs a big pad. Copying 600 eDPI on a small pad leaves no room to swing, so pick a number your desk can actually fit.
Common questions
How do I calculate eDPI?
Multiply your mouse DPI by your in-game sensitivity. 800 DPI times 0.5 sensitivity is an eDPI of 400. That single number is your true aim speed, which lets you compare setups across different mice and games.
What is cm/360 and how is it different from eDPI?
cm/360 is the physical distance your mouse travels to spin a full 360 degrees in game. It equals 914.4 divided by your eDPI. A higher eDPI means a shorter, faster cm/360; a lower eDPI means more desk space per turn and more precision.
If I change my mouse DPI, do I lose my aim?
Only if you forget to rematch the sensitivity. To keep the same feel, set new sensitivity = old DPI times old sensitivity, divided by new DPI. Pros keep DPI fixed and tune the in-game slider precisely for this reason.
