eDPI Calculator
This eDPI calculator calculates your true effective sensitivity using your hardware mouse DPI and in-game sensitivity value. It eliminates guesswork when comparing settings across different gaming mice, helping you match your mechanical aim feel without manual trial and error. Whether you tune your aim for tactical shooters or fast-paced arena battle royales, it reveals whether your physical hand movement matches your intended target precision.
Recommended: 400-1600 DPI

Understanding DPI and eDPI Fundamentals
What is DPI?
DPI (Dots Per Inch) is your mouse sensor's resolution. It determines how many pixels your cursor moves for every inch you move your mouse physically.
- • Higher DPI = more cursor movement per inch
- • Common ranges: 400-1600 for competitive gaming
- • Beyond 1600 DPI can introduce sensor smoothing
- • Native DPI steps provide best accuracy
What is eDPI?
eDPI (effective DPI) combines your mouse DPI with in-game sensitivity to show your actual sensitivity across different setups.
- • Formula: eDPI = DPI × In-Game Sensitivity
- • Enables fair comparison between players
- • Independent of hardware differences
- • Standard metric in competitive gaming
Why cm/360 Matters
cm/360 tells you how many centimeters you need to move your mouse for a full 360° turn in-game. This is the most practical measurement for gaming.
Expert answers to common eDPI and gaming sensitivity questions
Basic Usage
What eDPI should I use?
Start with your game's pro average: CS:GO ~875, Valorant ~280, Fortnite ~55. Adjust based on your playstyle and comfort.
How do I calculate my eDPI?
Multiply your mouse DPI by your in-game sensitivity. For percentage sensitivity, divide by 100 first. Example: 800 DPI × 1.0 sens = 800 eDPI.
Professional Tips
Should I use high or low DPI?
400-800 DPI is optimal for most gaming mice. Higher DPI can introduce sensor smoothing, while lower DPI may cause pixel skipping.
How often should I change sensitivity?
Rarely. Consistency builds muscle memory. If you must change, adjust by max 10-15% and practice for at least a week before deciding.
Technical Details
What is cm/360 and why does it matter?
cm/360 is how many centimeters you move your mouse for a 360° turn. It's the most practical measurement for comparing sensitivities across different setups.
Is mouse acceleration bad for gaming?
Yes, avoid it completely. Acceleration makes movement unpredictable and prevents building consistent muscle memory essential for competitive gaming.
Game Conversions
How do I convert between games?
Use cm/360 for accurate conversion. Our calculator handles game-specific scaling automatically. Never just copy eDPI values between games.
Why do pro players use different eDPI for different games?
Each game has different sensitivity scaling, movement mechanics, and aiming requirements. What feels consistent is cm/360, not eDPI values.
