eDPI Calculator

Multiply your mouse DPI by your in-game sensitivity to get eDPI — the standard, DPI-independent number FPS players use to compare and match mouse sensitivity across games and hardware.

Quick Facts

eDPI = Mouse DPI x In-game Sensitivity
A DPI-independent number used to compare sensitivity across games and hardware.
Common range

Purely a convention, not a rule — playstyle and game matter more than the number.

About the eDPI Calculator

eDPI, short for "effective DPI," is the standard way competitive first-person shooter players compare mouse sensitivity across different games, mice, and DPI settings. It is calculated by multiplying your mouse's DPI (dots per inch, a hardware setting stored in your mouse or its software) by your in-game sensitivity multiplier (a software setting inside the game). Because eDPI folds both numbers into one, two players with very different individual DPI and sensitivity settings but the same eDPI move their crosshair the same physical distance for the same mouse movement.

The formula

eDPI = Mouse DPI x In-game Sensitivity

For example, a mouse set to 800 DPI with an in-game sensitivity of 0.4 gives an eDPI of 800 x 0.4 = 320. A different setup of 400 DPI and 0.8 sensitivity also produces an eDPI of 320 — even though the individual numbers look nothing alike, both setups move the crosshair the same amount per inch of physical mouse movement within the same game.

Why eDPI matters

  • Comparing setups: pro players and streamers often publish DPI and sensitivity as two separate numbers; eDPI turns them into one comparable figure.
  • Switching mice: if you change your mouse's DPI setting, you can solve for the new in-game sensitivity needed to keep your aim feeling identical.
  • Cross-game consistency: many players try to keep a similar eDPI as a starting point when picking up a new game, then fine-tune from there.

What this calculator does

Enter your mouse DPI and in-game sensitivity to get your eDPI. Enter a target eDPI — for example, a pro player's published setting you want to try — to see what sensitivity you would need at your current DPI to match it. Enter a different DPI you're considering switching to, and the calculator solves for the sensitivity that preserves your current eDPI at that new DPI.

What eDPI does not capture

eDPI does not account for a game's internal sensitivity scaling, field of view, monitor resolution, or mouse acceleration — two games can apply the same eDPI number very differently in terms of the actual centimeters of mouse movement needed for a full 360-degree turn. eDPI is most reliable as a same-game or same-engine comparison tool, or as a rough starting point when moving between games, not as an exact physical measurement.

Frequently Asked Questions

What is eDPI and how is it calculated?
eDPI (effective DPI) equals your mouse DPI multiplied by your in-game sensitivity multiplier. For example, 800 DPI at 0.4 sensitivity gives an eDPI of 320. It folds two separate settings into one number so setups with different DPI and sensitivity can be compared directly.
What eDPI do most competitive FPS players use?
There is no single correct eDPI. Many competitive first-person shooter players land somewhere in the 300 to 800 range, with some going lower for precision-focused aiming and others higher for fast flicks, but personal preference, game, and playstyle all matter more than copying a number.
Does the same eDPI feel identical in every game?
Not exactly. eDPI does not account for a game's internal sensitivity scaling, field of view, or monitor resolution, so the same eDPI can translate into a different actual turning distance from one game to the next. It is most reliable for comparing settings within the same game or engine.
How do I switch mice without changing how my aim feels?
Keep your eDPI constant. Divide your current eDPI by the new mouse's DPI to get the in-game sensitivity that reproduces the same effective DPI, so the same physical hand movement moves your crosshair the same distance as before.
