Understanding eDPI and Sensitivity
eDPI (effective Dots Per Inch) is the standard metric for comparing mouse sensitivity across different hardware and game settings. The formula is simple: eDPI = Mouse DPI × In-game Sensitivity. This single number lets you replicate your aim feel on any setup, regardless of which mouse or DPI you use.
The eDPI Formula Explained
Your mouse DPI determines how many pixels the cursor moves per inch of physical movement. In-game sensitivity then multiplies this value. For example, 800 DPI with 0.5 sensitivity gives 400 eDPI, identical to 400 DPI with 1.0 sensitivity. Both setups move your crosshair the same distance for the same hand movement. This is why eDPI is the universal comparison metric among competitive players.
What is cm/360?
cm/360 measures how many centimeters of mouse movement completes a full 360-degree turn in-game. Lower eDPI means higher cm/360 (more desk space needed). Most Valorant pros use 30-60 cm/360, while CS2 pros often prefer 20-40 cm/360. This metric helps when switching between games with different sensitivity scales. A larger mousepad (40cm+) is recommended for low-sensitivity players.
Per-Game Sensitivity Scaling
Each game interprets sensitivity values differently. Valorant uses a 0.001 multiplier base, making raw numbers appear small (0.2-0.8 typical). Counter-Strike 2 uses larger values (1.0-3.0 typical) with a different internal calculation. Apex Legends, Overwatch 2, and other titles each have unique scaling. Always convert to eDPI or cm/360 when comparing across games to ensure accurate sensitivity matching.
Finding Your Ideal Sensitivity
- Start with a pro player's eDPI in your preferred range, then adjust gradually over several practice sessions.
- Lower eDPI (200-400) offers precision for headshots but requires larger mouse movements and more desk space.
- Higher eDPI (600-1200) enables faster flicks and 180-degree turns but reduces fine-aim control at distance.
- Ensure your mousepad is large enough for your cm/360 requirement—at least 40cm wide for most competitive players.
- Stick with one sensitivity for at least a week before making changes to build consistent muscle memory.
Common eDPI Mistakes to Avoid
These errors can hurt your aim consistency and slow your improvement.
Changing sensitivity too often
Muscle memory takes 1-2 weeks to develop. Switching sensitivity every few days resets your progress. Pick an eDPI within the pro range for your game and commit to it for at least 7 days before adjusting.
Ignoring cm/360 when switching games
A 0.5 sensitivity in Valorant is not the same as 0.5 in CS2. Always convert to cm/360 or eDPI when transferring settings between games. Use this calculator to find equivalent values.
Using extremely high or low eDPI
Below 100 eDPI requires 130+ cm for a 360, impractical for most desks. Above 1500 eDPI makes micro-adjustments nearly impossible. Stay within 150-1200 eDPI for most FPS games.
Forgetting to disable mouse acceleration
Windows 'Enhance pointer precision' adds acceleration that makes cursor speed inconsistent. Disable it in Windows settings and enable raw input in your game for 1:1 mouse movement.
eDPI Deep Dive: Technical Details
Understanding the technical foundations of eDPI helps you make informed decisions about your sensitivity setup. Here we cover the math, hardware considerations, and game-specific nuances that affect your aim. For a complete beginner's guide, see our What is eDPI?.
How Mouse DPI Works
DPI (Dots Per Inch) measures how many pixels your cursor moves per inch of physical mouse movement. A 400 DPI mouse moves the cursor 400 pixels when you move the mouse one inch. Higher DPI (1600, 3200) means more cursor movement per inch. Modern gaming mice support 100-25600 DPI, but most pros use 400-1600 DPI. Higher DPI reduces input lag slightly (sub-millisecond) but the difference is imperceptible for most players.
Sensor Accuracy and Native DPI
Every mouse sensor has a native DPI where it performs optimally without interpolation. For example, the PixArt PMW3360 sensor has a native DPI of 1600. Using non-native DPI values forces the sensor to interpolate, potentially introducing smoothing or jitter. Check your mouse manufacturer's specifications to find the native DPI. Many competitive players choose 800 or 1600 DPI as these are common native values across popular gaming mice.
Windows Pointer Settings
Windows has its own pointer speed setting (6/11 is default, 1:1 ratio). Most FPS games bypass Windows sensitivity entirely through raw input, but some older titles or desktop aim trainers may be affected. Always enable raw input in your game settings when available. If your game lacks raw input, set Windows pointer speed to 6/11 and disable 'Enhance pointer precision' (mouse acceleration) for consistent tracking.
Polling Rate Impact
Polling rate (125Hz, 500Hz, 1000Hz) determines how often your mouse reports position to the PC. At 1000Hz, the mouse reports every 1ms. Higher polling rates provide smoother cursor movement and reduce input lag. Most gaming mice default to 1000Hz. While 4000Hz and 8000Hz mice exist, the improvement over 1000Hz is minimal for most players. Ensure your USB port supports the polling rate—some USB hubs limit to 125Hz.
