Overwatch 2 eDPI Calculator

What is eDPI, and why does it matter?

Two players can run wildly different settings and still move their crosshair at the exact same speed. That is because in-game sensitivity numbers are relative — a sensitivity of 1 means nothing on its own. eDPI (effective dots per inch) fixes this by combining the two values that actually decide cursor speed: your mouse's hardware DPI and your in-game sensitivity.

Because eDPI is a single, hardware-independent number, it is the standard way to compare aim settings between players in Overwatch 2. A lower eDPI means slower, more precise aim that rewards arm movement; a higher eDPI means faster turns with less desk space but less fine control.

The eDPI formula

The math is deliberately simple:

eDPI = mouse DPI × in-game sensitivity

So 800 DPI at a sensitivity of 5 gives 4000 eDPI. Double the DPI or double the sensitivity and your eDPI doubles — your hand moves the crosshair twice as far for the same swipe.

For Overwatch 2 we can go one step further and convert eDPI into cm/360 — the centimetres of mouse travel needed for a full 360° spin — because the game uses a fixed turn-per-count value (yaw). Lower cm/360 = faster; it is the most honest cross-game comparison there is.

cm/360 = (360 ÷ (yaw × sens)) ÷ DPI × 2.54

How to use this Overwatch 2 eDPI calculator

1. Enter your mouse DPI. Type the DPI (CPI) set in your mouse software or on-mouse button — commonly 400, 800 or 1600.
2. Enter your Overwatch 2 sensitivity. Copy the in-game sensitivity value from Overwatch 2's settings.
3. Read your eDPI. The calculator instantly multiplies the two to show your eDPI, along with cm/360 and inches/360.
4. Compare and fine-tune. Match your eDPI against players you want to emulate, then adjust DPI or in-game sens to land on it.

Worked example

Say you play at a common 800 DPI and the typical Overwatch 2 sensitivity of 5. Your eDPI is 800 × 5 = 4000. That is roughly 34.6 cm of mouse movement for a full 360° turn. If you later switched to 1600 DPI but wanted the same feel, you would halve your in-game sensitivity to 2.5 to keep eDPI at 4000.

Finding a good eDPI for Overwatch 2

There is no single "correct" eDPI — the right value is the one your muscle memory can repeat. Use this quick test instead of chasing a pro's number:

• The 180° swipe test. A comfortable single swipe across your mousepad should turn you about 180°. If you run out of pad before facing the enemy behind you, your eDPI is too low; if a tiny flick over-turns, it's too high.
• Lower for precision, higher for speed. Tactical aimers and snipers trend lower; fast, movement-heavy or 360-flick styles trend higher.
• Pick one and commit. Consistency beats the "perfect" number. Stick with a value for a few weeks before judging it.

Only ever compare eDPI with players in the same game, since each title scales sensitivity differently. To compare across games, use cm/360 instead — it cancels out every scaling difference.

Tips for a consistent setup

• Match cm/360 across games so your aim transfers — set each game's sensitivity until the cm/360 lines up.
• Clear desk space. Low eDPI needs room; make sure a full swipe never hits your keyboard or the edge of the pad.
• Change one thing at a time. Adjust eDPI or DPI, never both at once, so you can feel the difference.
• Write your settings down. After a Windows reset or new mouse, you can restore the exact same feel from your eDPI.
