DPI vs eDPI for FPS games
Players trade DPI numbers as if they settle an argument, but DPI alone does not tell you how fast someone actually aims. The number that matters is eDPI, and cm/360 matters even more across games.
Bottom line
DPI is your mouse sensor setting. eDPI is DPI multiplied by your in-game sensitivity, and it is what actually decides your turn speed inside one game. To compare across different games, use cm/360, because each game scales sensitivity differently.
Do not buy on a guess. Check your exact setup in 60 seconds and see the one part that matters.

What DPI is
DPI is how many counts your mouse reports per inch of movement. On its own it does not fix your aim speed, because the game sensitivity multiplies it.
- 800 and 1600 DPI are common starting points.
- Higher DPI is not better, it just needs a lower in-game sensitivity.
- Very high DPI can add sensor noise on some mice.
What eDPI is
eDPI is DPI times in-game sensitivity. It is the fair way to compare two players inside the same game, because it folds both numbers into one.
- 800 DPI at 0.5 sens is 400 eDPI, the same as 1600 DPI at 0.25.
- Lower eDPI means slower, steadier aim. Higher means faster.
- Pros in tactical shooters often sit in a fairly low eDPI range.
Why cm/360 wins across games
eDPI only compares within one game, because each game uses a different sensitivity scale. cm/360 is the physical distance your mouse travels for a full turn, so it works everywhere.
- The same eDPI turns different amounts in different games.
- cm/360 is the real, cross-game measure of your aim.
- Match cm/360 when you switch games to keep your muscle memory.
How to use these numbers
Pick one eDPI you trust, then carry its cm/360 into every game you play.
- Find your eDPI and cm/360 with the calculators.
- When moving games, convert by cm/360, not by copying the sensitivity number.
- Change one variable at a time so you can feel the difference.
