eDPI Calculator: Find Your True Mouse Sensitivity

Calculate your effective DPI (eDPI) to accurately compare mouse sensitivity across FPS games.

What is eDPI?

eDPI stands for Effective Dots Per Inch. It represents your true mouse sensitivity by combining your mouse’s DPI setting with your in-game sensitivity.

Because games scale sensitivity differently, raw DPI alone is meaningless for comparison. eDPI solves this by producing a single standardized value that reflects how fast your crosshair actually moves.

Why eDPI Matters in Competitive FPS Games

In tactical shooters like Valorant and CS:GO, consistency matters more than speed. eDPI allows players to:

Compare sensitivity accurately between players
Replicate the same mouse feel across different DPI settings
Maintain consistent aim when switching mice or games

This is why eDPI is the standard metric used by professional players and coaches.

eDPI Formula

1
eDPI = Mouse DPI × In-Game Sensitivity
2
DPI is set in your mouse software or hardware buttons.
3
Sensitivity is the value set inside the game.

How to Calculate eDPI Step by Step

1
Check your mouse DPI setting.
2
Open your game and note your sensitivity value.
3
Multiply DPI by sensitivity.
4
The result is your eDPI.

eDPI Examples

Example 1
800 DPI × 0.35 sensitivity = 280 eDPI.

Example 2
400 DPI × 0.70 sensitivity = 280 eDPI.

Even though the DPI and sensitivity values differ, both players have the exact same effective sensitivity.

Typical eDPI Ranges for FPS Games

While there is no perfect eDPI, competitive data shows clear trends:

Low eDPI (200–280): High precision, arm aiming, common among professional riflers.
Medium eDPI (280–400): Balanced control and speed.
High eDPI (400+): Faster movement, less precision, more wrist-dependent.

Most professional Valorant and CS players stay below 400 eDPI.

Common eDPI Mistakes

Changing DPI without adjusting in-game sensitivity.
Comparing sensitivity values across games instead of eDPI.
Assuming higher eDPI means better aim.
Copying pro settings without matching physical desk space.

eDPI FAQs

What is a good eDPI for Valorant?

Most professional Valorant players use between 200 and 400 eDPI, with many clustering around 250–300 for maximum control.

Is lower eDPI always better?

No. Lower eDPI improves precision but requires more arm movement and desk space. The best eDPI is one you can control consistently.

Does eDPI work the same in all games?

eDPI standardizes sensitivity within a game, but different games use different sensitivity scaling. Always calculate eDPI per game.

Does mouse polling rate affect eDPI?

No. Polling rate affects input responsiveness, not sensitivity. eDPI depends only on DPI and in-game sensitivity.
