What is eDPI?

If you play PC games, especially shooters like Valorant, CS:GO, or Apex Legends, you may have heard of the term eDPI. Many pro players and gaming guides talk about it while discussing mouse sensitivity. But do wonder What is eDPI? and why is it important? Let’s break it down in simple words.

Meaning of eDPI

eDPI stands for Effective Dots Per Inch. It’s a value that combines your mouse DPI and your in-game sensitivity.

The formula is very simple:

eDPI = Mouse DPI × In-game sensitivity

Example:

• If your mouse DPI = 800
• Your in-game sensitivity = 0.5
• Then your eDPI = 800 × 0.5 = 400

This number (400 eDPI) tells how fast your crosshair will move in-game.

Why is eDPI Important?

Different games allow different sensitivity settings. If you only look at “DPI” or only at “in-game sensitivity,” you won’t get the full picture of it.

• Fair comparison: You can compare your sensitivity with other players regardless of what DPI their mouse is set to.
• Finding comfort: Helps you figure out if your sensitivity is too high or too low.
• Pro player settings: Most pro players share their eDPI, so you can easily copy or adjust to their level.

Best eDPI for Gaming

• Low eDPI (e.g., 200–400): Slower crosshair movement, better precision, commonly used in FPS games.
• High eDPI (e.g., 800+): Faster crosshair movement, less precise, but useful for fast reflex gameplay.

There is no “Best” or “Perfect” eDPI — it all depends on your gaming playstyle and comfort. However, most of the Pro FPS players usually says that 250–450 eDPI range is good.

How to Calculate eDPI?

• Find your mouse DPI (by using our mouse dpi checker tool).
• Check your in-game sensitivity.
• Multiply them together. (like- mouse dpi × in-game sensitivity)

Or, use our eDPI calculator - just enter the numbers, and it gives the result instantly.

Conclusion

eDPI is simply a way to measure your true mouse sensitivity in games. It’s a combination of DPI and in-game sensitivity, making it easy to compare settings with other players. If you want to improve your aim, just experiment with different eDPI values and stick to whichever suites you the most.
