DPI & eDPI Calculator

Client-Side New

Understand and optimize your mouse sensitivity with the DPI and eDPI calculator. Enter your mouse DPI and in-game sensitivity to instantly see your effective DPI (eDPI) and the physical distance in centimeters needed for a full 360° turn. Compare your setup against pro player benchmarks for CS2, Valorant, Apex Legends, Overwatch 2, and Fortnite. Use the built-in sensitivity converter to transfer your muscle memory between games with mathematically precise conversions based on each game's yaw value.

How to Use

  1. 1

    Enter Mouse DPI

    Input your mouse DPI setting or select a common preset (400, 800, 1600, 3200). Check your mouse software if unsure of your current DPI.

  2. 2

    Enter In-Game Sensitivity

    Type your in-game sensitivity value and select the game from the dropdown to use the correct yaw constant for calculations.

  3. 3

    View Your Results

    Instantly see your eDPI (DPI × sensitivity) and cm/360° distance. Compare against pro player benchmarks for your selected game.

  4. 4

    Convert Between Games

    Use the sensitivity converter section to transfer your exact sensitivity to another game while maintaining the same physical mouse feel.

Examples by Niche

CS2 Pro Comparison

Enter 400 DPI and 1.6 sensitivity to get 640 eDPI — matching s1mple's setup with a 52.1 cm/360° distance.

Valorant to CS2

Convert Valorant 0.35 sens at 800 DPI to CS2: the converter calculates the equivalent CS2 sensitivity of 1.114 for identical aim feel.

Finding Your 360° Distance

Enter your DPI and sensitivity to discover your cm/360° — then measure your mousepad to see if you have enough space for a full turn.

DPI Comparison

Compare 400 DPI × 2.0 sens vs 800 DPI × 1.0 sens — both produce 800 eDPI and 28.9 cm/360° in CS2, proving they feel identical.

Frequently Asked Questions

What is eDPI and why does it matter?

eDPI (effective Dots Per Inch) is your mouse DPI multiplied by your in-game sensitivity. It represents your true sensitivity regardless of DPI/sens combination. For example, 400 DPI × 2.0 sens and 800 DPI × 1.0 sens both produce 800 eDPI and feel identical in-game. eDPI makes it easy to compare setups across players and hardware.

What is cm/360° and how is it calculated?

cm/360° is the physical distance in centimeters your mouse must travel to rotate your in-game view 360 degrees. It is calculated as (360 / (DPI × sensitivity × yaw)) × 2.54, where yaw is a game-specific constant. Lower cm/360 means higher sensitivity. Most pro FPS players use 20-50 cm/360.

How does sensitivity conversion between games work?

Each FPS game uses a different "yaw" value that determines how much the camera rotates per mouse count. To convert sensitivity: new_sens = (old_sens × old_yaw) / new_yaw. This preserves your cm/360° across games, so your muscle memory transfers perfectly.

What eDPI do pro players use?

In CS2, most pros use 600-1000 eDPI (e.g., s1mple: 640, ZywOo: 800, NiKo: 552). In Valorant, pros typically use 200-400 eDPI (e.g., TenZ: 320, Aspas: 280). Lower eDPI gives more precision for headshots but requires more desk space and arm movement.
