eDPI Calculator

Your eDPI = DPI × in-game sens — the single number that tells you your true aim speed. Get your eDPI plus cm/360 instantly, and see exactly where you sit against recommended ranges by game and role.

What is eDPI?

eDPI stands for effective dots per inch. It is the simplest, most honest way to describe how fast your aim actually is, because it folds your two sensitivity settings — hardware DPI and in-game sens — into one number:

eDPI = mouse DPI × in-game sensitivity

Why does this matter? Because raw in-game sens alone is meaningless without DPI. A player on 400 DPI × 2.0 sens and a player on 800 DPI × 1.0 sens have completely different settings menus but the exact same aim speed — both are 800 eDPI. When pros and coaches compare sensitivities, they compare eDPI, not the in-game slider.

How to calculate eDPI (worked examples)

The calculator above does this instantly and also prints your cm/360, because eDPI on its own does not tell you the physical distance your hand travels — for that you need the game's yaw constant, which the tool applies automatically.

Recommended eDPI ranges by game

These ranges come from publicly published pro settings. Use them as guard rails, not gospel — your ideal eDPI depends on grip, desk space and playstyle.

eDPI vs cm/360 — do not confuse them

This trips up a lot of players, so be clear: eDPI only compares inside one game. An eDPI of 320 is a different physical turn speed in Valorant than in CS2, because the two engines scale sensitivity differently (Valorant's yaw is 0.07, CS2's is 0.022). The number that is identical everywhere is cm/360 — the centimetres of mouse travel for a full turn.

So: use eDPI to compare yourself to other players in the same game, and use cm/360 to carry your aim across games. If you are switching titles, run your settings through the sensitivity converter (it matches cm/360) rather than copying eDPI. To isolate just the physical distance, the cm/360 calculator does only that.

How to pick your eDPI

  1. Can you do a clean 180? Stand in a corner, flick a 180 with one arm sweep. If you run out of mousepad, your eDPI is too low for your desk. If a tiny twitch over-rotates, it is too high.
  2. Match the role you play. Use the role table above as a starting band.
  3. Lock it for 60 hours. The single biggest aim killer is changing eDPI during a slump. Pick one number, train it, and only adjust after a real sample of games.
  4. Train it deliberately. Burn the new eDPI into muscle memory in the aim trainer before you take it to ranked.

FAQ

What is eDPI?

eDPI stands for effective dots per inch. It is your mouse DPI multiplied by your in-game sensitivity: eDPI = DPI × sens. It lets two players with different mice compare their true in-game speed. For example, 400 DPI × 2.0 and 800 DPI × 1.0 are both 800 eDPI and feel identical in the same game.

How do I calculate eDPI?

Multiply your mouse DPI by your in-game sensitivity. If you play CS2 at 800 DPI with sens 1.0, your eDPI is 800 × 1.0 = 800. If you play Valorant at 1600 DPI with sens 0.2, your eDPI is 1600 × 0.2 = 320.

What is a good eDPI for Valorant?

Most Valorant pros sit between 200 and 400 eDPI, with the cluster around 280 to 320. aspas runs 320 (0.40 at 800 DPI) and TenZ runs 280. Lower eDPI favours precise tap-firing; higher eDPI helps run-and-gun and fast repositioning.

Is eDPI the same as cm/360?

No. eDPI is a digital number that only compares players inside the same game. cm/360 is a physical mouse distance that is the same across every game. An eDPI of 320 means different speeds in Valorant versus CS2, but a cm/360 of 40 is always 40 cm of desk movement.

Does eDPI transfer between games?

No. Each engine uses a different yaw constant, so the same eDPI is a different turn speed in each game. To carry your aim across games, match cm/360 with a sensitivity converter, not eDPI.

Should I lower my eDPI to aim better?

Not automatically. Lower eDPI (higher cm/360) gives more precision but needs arm aiming and desk space. Higher eDPI is faster but harder to micro-adjust. Pick an eDPI that lets you do a full 180 comfortably, then keep it for at least 60 hours before changing.
