What eDPI means
eDPI, effective DPI, is your mouse DPI multiplied by your in-game sensitivity. It folds two settings into one number. A player on 400 DPI at 0.8 and a player on 800 DPI at 0.4 both have an eDPI of 320, and their crosshairs move exactly the same distance for the same hand movement. That is why people quote eDPI instead of DPI or sensitivity alone, and why the eDPI calculator asks for both.
Pick your game, type your DPI and sensitivity, and you get your eDPI, how far you move the mouse for a full turn (cm/360), where that sits from fast to slow, and the sensitivity that keeps the same eDPI if you switch to another DPI.
eDPI only compares within one game
Each game turns by a different angle per count, so 320 eDPI in Valorant and 320 eDPI in CS2 feel nothing alike. Valorant's step is 3.18 times bigger than CS2's, so 320 Valorant eDPI matches about 1,018 in CS2. When you compare across games, compare cm/360, or let the sensitivity converter do the sum for you.
Fortnite is the odd one: its slider is a percentage, and eDPI uses it as a decimal, so 6.4% at 800 DPI is 51.2. In Rainbow Six Siege the result also depends on the MouseSensitivityMultiplierUnit in your settings file; the calculator assumes the default 0.02 unless you change it.
How to read your result
The scale under the tool sorts by cm/360, because that is what your arm feels. The bands are a common convention, not a rule:
- High sensitivity, under 25 cm: a flick of the wrist turns you all the way round. Fast to react, harder to hold steady on a small target.
- Medium, 25 to 45 cm: wrist and arm share the work. Common in faster games with a lot of tracking.
- Low, over 45 cm: you aim from the elbow or shoulder and need a big pad. Steady for precise shots, and typical of tactical shooters.
For three games there is a published pro figure to compare with. prosettings.net puts the median eDPI of the CS2 pros it tracks at 830 (September 2026), which is about 50 cm per turn, and the median for Valorant pros at 240 (May 2026), about 54 cm. For Overwatch it gives no eDPI but says the average pro needs about 35 cm for a full turn. We don't show pro figures for other games because no single published number backs them. A pro median is a reference point, not a target: plenty of good players sit far from it on both sides.
The maths
eDPI = DPI × sensitivity. cm/360 = 360 ÷ (eDPI × yaw) × 2.54, where the yaw is the angle the game turns per count at sensitivity 1 (0.022° in CS2, 0.07° in Valorant). Worked through for CS2 at 800 eDPI: 800 × 0.022 = 17.6° per inch, 360 ÷ 17.6 = 20.45 inches, × 2.54 = 51.95 cm per turn.
To keep your eDPI on a new DPI, divide: sensitivity = eDPI ÷ DPI. 800 eDPI at 1600 DPI is 0.5. Not sure of your real DPI? The DPI analyzer measures it, since a sensor a few percent off the box moves your eDPI by the same few percent.
Finding a sensitivity that suits you
- Change one thing at a time, in small steps, and play a few sessions before judging.
- Check your space. At 50 cm per turn, a quick 180° needs 25 cm of pad. If you keep running off the edge, go faster or get a bigger pad.
- Prefer 800 or 1600 DPI and set the in-game sensitivity to suit. Very low DPI with a high in-game number makes the crosshair move in visible steps.
- Turn off pointer acceleration in Windows and use raw input in games that offer it, so the same eDPI always turns the same distance.
Practise the result on the aim trainer: if flicks keep overshooting, try a slightly lower eDPI; if you can't keep up with a moving target, a slightly higher one.
Questions
What is a good eDPI for Valorant?
The median among the Valorant pros prosettings.net tracks is 240, about 54 cm per turn. Plenty of good players sit well above or below it. Use the Valorant eDPI calculator above to see where your setting lands.
What is a good CS2 eDPI?
Tracked CS2 pros have a median of 830, roughly 50 cm per turn. Good players range well either side of that; pick what lets you both flick and hold an angle.
Is a higher DPI better?
Not by itself. Speed comes from eDPI. A higher DPI only makes each step smaller, so you can lower the in-game sensitivity for the same speed with finer control.
Is eDPI the same as cm/360?
They describe the same thing from different sides. eDPI ignores the game's turn angle, so it only compares within one game. cm/360 includes it, so it compares across games.
Why do my friend and I have the same eDPI but different feel?
Different mice, weights and pads change how a movement feels even when the turn is identical. Field of view and monitor size change how fast it looks.
If your mouse is fighting you, the mouse finder sorts by weight, shape and grip.
