🖱 Turn your DPI and in-game sensitivity into one number you can compare.
Enter your mouse DPI and sensitivity to get your eDPI and how far your mouse travels for a full 360° turn. Then see the same feel in other games, or work backwards from a target.

What eDPI Tells You (and What It Doesn't)
Ask ten players what sensitivity they use and you'll get ten answers in different units: a DPI, a number in the game's settings menu, sometimes just "pretty low." eDPI folds the first two into a single number so two setups can be compared at a glance. It's useful, but only inside its limits, and those limits are where most of the confusion comes from.
The Formula
eDPI stands for effective DPI, and the math is a single multiplication: your mouse DPI times your in-game sensitivity. A mouse set to 800 DPI with a sensitivity of 0.4 gives you 320 eDPI. Set the same mouse to 1600 DPI and drop the sensitivity to 0.2, and you're still at 320. The cursor, or crosshair, moves exactly the same distance for the same hand movement, which is the whole point of the number.
Why eDPI Doesn't Travel Between Games
Every game decides for itself how many degrees of rotation one mouse count produces at sensitivity 1. That value is usually called yaw. Valorant uses 0.07, CS2 and Apex Legends use 0.022, and Overwatch 2 uses 0.0066. So 300 eDPI in Valorant and 300 eDPI in CS2 are not the same speed at all; the Valorant setup turns more than three times as far for the same hand movement.
That's why eDPI is best for comparing players or setups within one game. If a streamer mentions their Valorant eDPI and yours is higher, you know yours is faster. If they're playing a different game, the number alone won't tell you.
cm per 360°: The Number That Does Travel
The more honest measure is how far your hand moves to spin a full circle. The formula adds the game's yaw: 360 divided by (DPI × sensitivity × yaw) gives inches per 360°, and multiplying by 2.54 converts that to centimetres. Using the earlier example in Valorant, 800 × 0.4 × 0.07 comes out to roughly 40.8 cm for a full turn.
Because it's a physical distance, cm per 360° can be compared across games and even across players with different mousepads. As a rough guide, under about 20 cm counts as very high sensitivity, 20 to 35 cm as high, 35 to 50 cm as medium, 50 to 70 cm as low, and anything above that as very low. These bands are loose; plenty of good players sit outside the middle of them.
Converting Between Games
To keep the same feel in a new game, you keep the same cm per 360° and let the sensitivity change. At the same DPI, the new sensitivity is your old one multiplied by the old game's yaw and divided by the new game's yaw. Going from Valorant 0.4 to CS2 works out to about 1.27. The calculator above does this for you in the "Same feel in other games" panel.
Treat the result as a starting point. Scoped or zoomed sensitivity, field of view, and per-game scaling can still make the new game feel a little different, so expect to nudge it.
Common Mistakes
- Mixing up DPI and polling rate. Polling rate (125, 500, 1000 Hz and so on) is how often the mouse reports its position. It has no effect on eDPI.
- Changing DPI without changing sensitivity. Doubling your DPI doubles your eDPI. If you switch DPI, adjust the in-game sensitivity to keep the number you wanted.
- Leaving pointer acceleration on. Windows' "Enhance pointer precision" makes speed depend on how fast you move, which breaks any calculation. Turn it off, and use raw input in games that offer it.
- Copying a pro's eDPI and expecting the same result. Their mousepad size, grip, and monitor all differ from yours. Their number is a reference point, not a prescription.
Finding a Sensitivity That Fits
A practical approach: pick a starting cm per 360° in the medium range, set it with the "Find a sensitivity" panel, then play with it for several sessions before changing anything. When you do adjust, make small changes, around five to ten percent, so you can tell whether the new value helped. An aim trainer is a handy place to compare settings under the same conditions, since the targets and timer don't change between runs.
FAQ
eDPI is effective DPI: your mouse DPI multiplied by your in-game sensitivity. It gives one number you can use to compare mouse speed between setups in the same game.
It depends on the game, because each game scales sensitivity differently. In Valorant, many players land somewhere in the low hundreds; in CS2, values in the high hundreds to around a thousand are common. The best value is the one that lets you aim consistently with your own desk space and grip.
For cursor speed, no: 800 DPI at 0.4 and 1600 DPI at 0.2 give the same eDPI and the same movement. Some players prefer a higher DPI for smoother tracking, and others stick with 400 or 800, so it mostly comes down to preference.
Check that you're playing the same game, since the same eDPI means different speeds in games with different yaw values. Pointer acceleration, in-game scoped sensitivity, and field of view can also change how fast a setup feels.
No. eDPI covers your normal hip-fire sensitivity. Scopes and zoom levels usually have their own multipliers, which you set separately in the game.
