eDPI Calculator for CS2: Find Your Perfect Aim Sensitivity Instantly

What Is eDPI — and Why Every CS2 Player Should Care

If you’ve ever switched mice or PCs and suddenly your aim felt off, it’s because your real sensitivity changed — even if your in-game number didn’t.

That’s where eDPI (effective dots per inch) comes in.

eDPI = DPI × In-Game Sensitivity

It’s a single number that represents your true aim speed, no matter what mouse, monitor, or setup you’re using.
Two players with different DPIs can have identical eDPI — and therefore, identical aim feel.

How the CS2 eDPI Calculator Works

Our CS2 eDPI calculator takes your:

• Mouse DPI
• In-game sensitivity

…and outputs your eDPI, centimeters per 360°, and inches per 360° (how far your mouse must move for a full rotation).

It even features an interactive Plotly.js chart that visualizes your movement curve — helping you see how tiny sensitivity tweaks affect aim.

The Math Behind the Magic

For those who like to peek under the hood:eDPI=DPI×SensitivityeDPI=DPI×Sensitivity

To convert that into physical movement, CS2 uses a yaw constant — usually 0.022 degrees per count:Counts per 360°=360Sensitivity×YawCounts per 360°=Sensitivity×Yaw360​Inches per 360°=Counts per 360°DPIInches per 360°=DPICounts per 360°​Centimeters per 360°=Inches per 360°×2.54Centimeters per 360°=Inches per 360°×2.54

You can adjust the yaw in the calculator’s Advanced section if you’re on a custom server or mod.

Step-by-Step: Using the eDPI Calculator

1. Enter your mouse DPI (commonly 400, 800, or 1600).
2. Enter your CS2 sensitivity (exactly as shown in-game).
3. (Optional) Open “Advanced” to verify or change yaw — default is 0.022.
4. Instantly view your:
   • eDPI
   • cm/360 and inches/360
   • Sensitivity chart (your point highlighted)
5. Use presets for quick testing (e.g., DPI = 400 or 800).
6. To transfer sensitivity between PCs, match your eDPI or cm/360 values.

How to Interpret Your Results

Pro tip: eDPI helps match aim feel, but cm/360 is the real-world movement metric that defines your muscle memory.

A lower eDPI = more control.
A higher eDPI = faster turns, but riskier precision.

Why Visualization Matters (Plotly Chart)

Sensitivity isn’t linear — changing from 1.0 to 1.1 feels totally different than 2.0 to 2.1.

That’s why the calculator’s Plotly.js chart is so valuable. It shows how small adjustments dramatically shift your physical movement distance, helping you dial in that “sweet spot” faster.

Advanced Use Cases

• Copy pro players: Find their DPI × sensitivity = eDPI, then test that value.
• Cross-device consistency: Match cm/360 when switching mice with different DPIs.
• Training logs: Track your sensitivity evolution — see if tweaks improve your aim over time.

Pro Tips for Consistency

Match eDPI, not just sensitivity, when switching setups.
Keep your DPI low (400–800) for more control.
Use a large mousepad to support low-sense precision.
Don’t chase pro settings blindly — find what feels right.

Disclaimer

Default CS2 yaw = 0.022 degrees per count.
If Valve changes it, or your custom server uses a different value, results will vary slightly.

The calculator provides best estimates — always test and fine-tune in-game.

FAQ: Quick Answers for Gamers

Q: What’s the default yaw value?
A: 0.022 (same as CS:GO). Change it under “Advanced” if needed.

Q: Is eDPI all that matters?
A: No — monitor size, FOV, and mousepad all influence aim feel.

Q: How do I match my sensitivity on another PC?
A: Copy your eDPI or cm/360 — then adjust DPI or sensitivity to match.

Q: Are presets accurate?
A: They’re great starting points. Always test and refine.

Final Thoughts: Master Your Aim with Consistent Sensitivity

Consistent sensitivity is the secret weapon of elite aimers.
By using the CS2 eDPI calculator, you can finally quantify your true aim feel, replicate it across devices, and build muscle memory that doesn’t fade between setups.
