eDPI Calculator
A mouse at 800 DPI with 0.35 in-game sensitivity gives an eDPI of 280, right in the typical Valorant pro range. This eDPI calculator multiplies your mouse DPI by your in-game sensitivity to get effective DPI, the one number that lets players with different hardware compare how fast their aim actually turns. Same eDPI, same real sensitivity, whatever the mouse settings say. eDPI matters because DPI and in-game sensitivity are both just knobs, and neither one alone tells you how fast your crosshair actually moves. A player running 400 DPI with a high in-game sensitivity and a player running 1600 DPI with a low sensitivity can end up with identical aim speed, even though their raw settings look completely different. eDPI collapses those two numbers into one comparable figure, which is why it shows up constantly in pro player settings lists, sensitivity converters, and setup guides across competitive shooters.
Quick answer
eDPI = mouse DPI x in-game sensitivity. That is the entire formula.
eDPI
280
What this tells you
- •eDPI = mouse DPI x in-game sensitivity. That is the entire formula.
- •It exists because 1600 DPI at 0.175 sens and 400 DPI at 0.7 sens aim identically, both are 280 eDPI.
- •Lower eDPI means slower, more precise aim that needs more mousepad space and larger arm movements.
- •eDPI only compares within one game, since each game scales sensitivity differently.
- •Two players with different mice can still share the exact same aim feel as long as their eDPI numbers match.
How to Use
- 1Find your mouse DPI in its software (common values: 400, 800, 1600).
- 2Read your sensitivity from the game's settings menu.
- 3Multiply, or let the calculator do it, and compare against the typical ranges below.
- 4To copy a pro's feel on your own DPI, divide their eDPI by your DPI to get your target sensitivity.
- 5Keep Windows pointer speed at its default 6/11 setting before comparing eDPI, since a different pointer speed changes the real sensitivity without changing the eDPI number.
How It Works
Formula
eDPI = DPI x in-game sensitivityDPI is how many counts the mouse sends per inch of movement, and in-game sensitivity multiplies those counts into camera turn. Their product is the real turn rate per inch of mousepad. A player at 800 DPI and 0.35 sens (280 eDPI) turns exactly as fast as one at 1600 DPI and 0.175 sens (also 280), even though neither individual number matches.

Worked Examples
Typical Valorant pro setting
Most Valorant pros sit between 200 and 320 eDPI.
Classic CS2 setup
CS2 sensitivity runs on a different scale, so 800 eDPI there is a common moderate setting.
Matching a pro on different hardware
Same eDPI as 800 DPI at 0.35, so the aim feels identical despite different settings.
A typical Overwatch 2 setting
Overwatch 2 uses a much higher sensitivity scale than tactical shooters, so 4800 eDPI sits right in the game's typical 4000 to 6000 range.
A typical Fortnite setting
Fortnite's sensitivity scale runs much lower than Valorant or CS2, so 80 eDPI is a common setting inside its typical 60 to 100 range.
Typical eDPI Ranges by Game
Where most competitive players land. Scales differ per game, so compare within a column's game only.
| Game | Low | Typical | High |
|---|---|---|---|
| Valorant | 150 | 200-320 | 450 |
| CS2 | 500 | 700-1100 | 1600 |
| Apex Legends | 800 | 1200-1800 | 2400 |
| Overwatch 2 | 3000 | 4000-6000 | 8000 |
| Fortnite | 40 | 60-100 | 150 |
Why the same eDPI feels different across games
eDPI is only meaningful within a single game because each game applies its own internal multiplier to the sensitivity value before turning it into camera movement. A sensitivity of 1.0 in one game might turn the camera much faster or slower than a sensitivity of 1.0 in a different game, even before eDPI enters the picture.
That is why the reference table above lists separate typical ranges for each game instead of one universal range. Converting a feel from one game to another requires matching a shared physical measurement, such as centimeters of mouse movement per 360-degree turn, rather than comparing raw eDPI numbers directly.
Common mistakes
- Comparing eDPI across games. Each game multiplies sensitivity on its own scale, so 280 in Valorant and 280 in CS2 are wildly different speeds.
- Ignoring Windows pointer speed. Anything but the 6/11 default multiplies mouse input again and breaks the eDPI math.
- Copying a pro's sensitivity number without their DPI. Only the eDPI product transfers between setups.
- Changing eDPI every bad game. Aim consistency comes from muscle memory, which needs a stable setting for weeks.
- Assuming a lower eDPI is always more accurate. Precision also depends on mousepad space, arm control, and practice, not eDPI alone.
