In the competitive FPS community, eDPI (Effective Dots Per Inch) is frequently cited when discussing pro player configurations. However, relying on eDPI when switching between games like Valorant, CS2, Overwatch, or Apex Legends causes significant aim inconsistency.
Here is why eDPI fails as a cross-title metric and why cm/360° (Centimeters per 360-degree turn) is the definitive standard for motor memory retention.
1. What is eDPI and Where Does It Break?
eDPI is calculated using a straightforward formula:
The Limitation:
eDPI completely ignores the underlying game engine's yaw coefficient (angular rotation per mouse count).
Because every game engine uses proprietary yaw factors (Source engine uses 0.022, Valorant uses 0.07), eDPI cannot be translated across different games.
2. Why cm/360° is the Universal Metric
cm/360° measures the exact physical distance (in centimeters) your hand must move your mouse across your mousepad to execute a full 360-degree rotation in 3D space.
Because physical distance relies on bodily muscle memory (proprioception) rather than arbitrary software numbers, maintaining identical cm/360° guarantees identical flick distances across any shooter.
3. Universal Sensitivity Ranges (cm/360° Reference)
| Category | cm/360° Range | Recommended Genres | Example Pro Profiles |
|---|---|---|---|
| Ultra Low | 55 - 75 cm | Tactical Shooters (CS2, Valorant) | s1mple, NiKo |
| Medium / Tactical | 35 - 54 cm | Hybrid / Tactical (Valorant, Apex) | TenZ, aspas |
| Fast / Tracking | 24 - 34 cm | Battle Royale & Arena (Apex, OW2, Marvel Rivals) | Aceu, Ras |
| Ultra High | < 23 cm | Fast Melee / Fast Twitch Arena | Wrecking Ball, Genji specialists |
4. Convert eDPI and cm/360° Instantly
Instead of manually calculating complex trigonometry and radian conversions:
SensScale Sensitivity Converter
Calculate exact eDPI values, hardware cm/360° metrics, and cross-game yaw ratios in real time.
5. How to Measure Your Real-World cm/360° Accurately
- Place your mouse against the left edge of your mousepad or a ruler.
- In-game, align your crosshair with a distinct corner or wall marker.
- Move your mouse horizontally until your crosshair makes exactly one full 360° rotation and realigns with the marker.
- Measure the physical distance your mouse traveled on the pad with a tape measure.
For consistent results across games, let our SensScale Sensitivity Converter automatically compute this hardware distance down to sub-millimeter precision.
