eDPI Calculator

About the eDPI Calculator

eDPI (effective dots per inch) is the universal way to express mouse sensitivity in FPS games. It combines your hardware DPI and in-game sensitivity into a single number that represents your actual mouse speed.

Two players using different DPI and sensitivity settings can have identical aim speed if their eDPI matches. For example, 400 DPI × 2.0 sens = 800 eDPI is identical to 800 DPI × 1.0 sens = 800 eDPI.

This calculator computes your eDPI and translates it to cm/360 for a physical measurement of how far your mouse travels for a full in-game rotation.

Use the estimate as a planning baseline and adjust it once you have real session data from the game you are playing.

When This Page Helps

eDPI is the standard metric for comparing sensitivity settings. When someone shares their sensitivity, eDPI makes the comparison meaningful regardless of their DPI setting. Use it to match pro settings, compare with teammates, or fine-tune your own setup.

How to Use the Inputs

1. Enter your mouse DPI from your mouse software or hardware.
2. Enter your in-game sensitivity.
3. View your eDPI result.
4. Compare with recommended ranges for your game and role.
5. Optionally enter a yaw value for cm/360 calculation.

Example Calculation

Tips & Best Practices

• CS2 pro eDPI median is around 860.
• Valorant uses a different sensitivity scale ‒ don't directly compare eDPI between games.
• Lower eDPI favors precision; higher eDPI favors tracking and fast turns.
• Your mousepad size should accommodate your eDPI — low eDPI needs large pads.
• Keep your eDPI consistent when changing DPI by adjusting in-game sens proportionally.
• Most competitive FPS players fall between 600-1600 eDPI (CS2 scale).

eDPI as the Universal Metric

Before eDPI, sensitivity discussions were confusing. Players would share in-game sensitivity values without mentioning DPI, making comparisons impossible. eDPI solved this by providing a single number that captures actual mouse speed.

Finding Your Ideal eDPI

Start with the median eDPI for your game. Play 20-30 matches, noting if you consistently over-aim (eDPI too high) or under-aim (eDPI too low). Adjust by 5-10% and repeat. Converging on your ideal typically takes 1-2 weeks.

The eDPI and Skill Relationship

There's no correlation between eDPI and skill level. Top players span the full range. What matters is consistency — pick an eDPI and stick with it long enough to build muscle memory.

Frequently Asked Questions

• What is a good eDPI?

  There's no single best eDPI. In CS2, pros average around 860 eDPI with a range of 400-1600. In Apex Legends, higher eDPI (1200-2400) is common. Find what's comfortable for your game and play style.

• Is higher or lower eDPI better?

  Lower eDPI gives more precision for micro-adjustments and flick shots. Higher eDPI allows faster turns and smoother tracking. Most competitive players use low-to-medium eDPI with a large mousepad.

• Can I compare eDPI across different games?

  Only if the games use the same yaw value. CS2 and Apex share yaw 0.022, so their eDPIs are directly comparable. Overwatch and Valorant use different yaw values and need conversion.

• Why do pros use low eDPI?

  Low eDPI provides finer control over crosshair placement, which is critical in tactical shooters where single headshots matter. The tradeoff is needing larger mouse movements, which pros mitigate with proper arm-aim technique.

• Should I copy pro eDPI?

  Pro eDPI is a useful starting point but not a rule. Pros have thousands of hours at their sensitivity. Start near the average for your game, then adjust based on comfort. Monitor size, mousepad size, and play style all factor in.

• How do I change eDPI?

  Adjust either DPI or in-game sensitivity. To maintain eDPI while changing DPI, divide the new DPI into the old eDPI for the new sens. Example: Moving from 400 DPI to 800 DPI at eDPI 800: new sens = 800/800 = 1.0.
