What this DPI and sensitivity calculator does
This tool helps you keep a consistent mouse feel when you change DPI, switch games, or both. In competitive FPS games, tiny aiming changes matter, so getting a consistent setup can improve comfort, confidence, and tracking precision.
The calculator gives you:
- eDPI (effective DPI)
- Equivalent target sensitivity for your new DPI/game yaw
- cm/360 and in/360 to describe physical mouse travel
DPI vs sensitivity: quick breakdown
DPI (mouse hardware setting)
DPI means dots per inch. It controls how far your cursor/crosshair moves for each inch of mouse movement. Higher DPI means faster movement at the same in-game sensitivity.
In-game sensitivity (software multiplier)
Sensitivity is a multiplier used by the game engine. Even with the same DPI, different sensitivity values produce very different turn speeds.
eDPI (effective DPI)
eDPI is a simple way to compare setups inside the same game family:
eDPI = DPI × sensitivity
Example: 800 DPI × 1.20 sens = 960 eDPI.
Why yaw matters for cross-game conversion
Different games scale sensitivity differently. A value of 1.00 in one game is not equal to 1.00 in another. That difference is captured by a yaw constant. The calculator uses yaw to convert your sensitivity accurately between titles.
Core conversion formula:
Target Sens = (Current DPI × Current Sens × Current Yaw) / (Target DPI × Target Yaw)
Understanding cm/360 and in/360
cm/360 is the number of centimeters you move the mouse to turn exactly 360 degrees in-game. Many players prefer this metric because it is hardware-agnostic and easy to test on your mouse pad.
cm/360 = (2.54 × 360) / (DPI × Sens × Yaw)
How to use this in practice
- Pick a comfortable cm/360 range based on your game style.
- Use this calculator whenever you change DPI or game title.
- Keep your posture, mouse pad position, and Windows pointer settings consistent.
Good setup workflow (5-minute method)
- Start with your current main-game settings.
- Enter your current DPI, sensitivity, and game yaw.
- Choose target DPI and target game.
- Apply the calculated target sensitivity.
- Test for 10–15 minutes and fine-tune by very small increments (1–3%).
Common mistakes to avoid
- Changing DPI and sensitivity at the same time without tracking old values.
- Comparing sensitivity numbers directly across games without yaw conversion.
- Ignoring ADS/scoped multipliers when your game has separate values.
- Over-adjusting too quickly after one bad match.
FAQ
What is a “good” DPI?
There is no universal best value. Most FPS players use 400, 800, or 1600 DPI, then tune in-game sensitivity for preferred cm/360.
Should I prioritize eDPI or cm/360?
For cross-game consistency, cm/360 is usually more practical. eDPI is still useful for quick within-game comparisons.
Do I need exactly the same sensitivity in every game?
Not always. Matching base sensitivity is a strong starting point, but you may prefer slight game-specific adjustments due to FOV, movement speed, and recoil behavior.
Use this calculator as a baseline, then refine with real gameplay. Consistency plus deliberate practice beats constant setting changes every time.
