Formula
eDPI = Mouse DPI × In-game Sensitivity
cm/360 = 360 ÷ (DPI × Sens × Yaw) × 2.54

Calculate your effective DPI (eDPI) instantly — the universal standard for comparing mouse sensitivity across different setups.
Core Formula
eDPI = DPI × Sensitivity
For example, 400 DPI × Sensitivity 2.0 = eDPI 800. And 800 DPI × Sensitivity 1.0 also equals eDPI 800 — both settings produce identical actual control speed.
Why eDPI Matters
When someone says 'my sensitivity is 2', without knowing their DPI, the number is meaningless. eDPI unifies the measurement, letting you precisely replicate anyone's sensitivity settings regardless of their DPI.
eDPI vs cm/360
eDPI must be combined with the game engine's yaw value to convert to cm/360 physical distance. The same eDPI produces completely different cm/360 in different engines, so cross-game comparison requires yaw-aware conversion.
eDPI Speed Range Reference
The following ranges are for CS2 eDPI (yaw = 0.022). Other games need yaw-ratio conversion.
200–400
Very Low
Pure arm aiming, requires an extra-large mouse pad. Maximum precision but difficult 180° turns. Ideal for stationary AWP/sniper players.
400–800
Low
The most common range among FPS pros. Excellent balance of precision and mobility. CS2/Valorant competitive standard.
800–1200
Medium
Versatile setting. Very popular in Apex, Overwatch 2, and other games requiring frequent camera rotation.
1200–2000
High
Wrist-dominant control, suited for fast-paced shooters or battle royale games requiring wide area scanning.
2000+
Very High
Extreme speed, demands exceptional hand control. Used by some Fortnite build-focused players.
FAQ
Q.High DPI with low sensitivity or low DPI with high sensitivity?
With the same eDPI, high DPI + low sensitivity is generally better. Higher DPI means the mouse reports denser data points, providing finer per-pixel stepping at low sensitivity. However, exceeding the sensor's native DPI introduces interpolation noise, so don't blindly chase high DPI.
Q.Do I need to re-practice after changing DPI?
If you adjust sensitivity to maintain the same eDPI, control feel should be identical — no extra practice needed. But if you change the eDPI itself, plan for 1–2 weeks of adaptation training with the new setting.
Q.Can eDPI be compared directly across games?
No. Each game engine has a different yaw value, so the same eDPI number means completely different physical speeds in CS2 vs Valorant. For cross-game comparison, use cm/360 (physical rotation distance) — the true universal standard.
Q.Should I copy a pro player's eDPI?
Pro settings make a good starting point, but optimal sensitivity is personal — it depends on mousepad size, grip style, arm/wrist habits, and comfort. Use the PSA method to scientifically test your own ideal range.
