The number people actually compare

Works out effective DPI and the distance the mouse travels for a full turn, so settings can be compared between players.

Saying 'my sens is 2' means nothing without the DPI: at 400 it is one thing, at 3200 quite another. So players trade eDPI — DPI multiplied by in-game sensitivity. It is identical for everyone tuned to the same turn speed within one game.

But eDPI only compares inside a game: 800 in CS2 and 800 in Valorant are different speeds. There is one universal figure — centimetres per 360 degrees. That is the one to remember if you play more than one shooter.

What this calculator shows

eDPI as DPI times in-game sensitivity
The distance for a full turn and for a half turn
Which camp your setting falls into: low, medium or high sens

What to keep in mind

The calculation assumes mouse acceleration is off and the Windows pointer speed sits at 6/11, where the system does not scale counts.
Centimetres are measured across the pad: real hand movement is slightly more because of wrist rotation.

FAQs

How do I calculate eDPI?

Multiply mouse DPI by in-game sensitivity. 800 DPI at a sensitivity of 1.5 gives an eDPI of 1200.

What eDPI do professionals use?

In CS2 most sit between 700 and 1000, in Valorant between 200 and 320. Those numbers cannot be compared directly: the games use different internal constants.

How many centimetres per 360 is normal?

Between 30 and 50. Under 25 is high sens for wrist aiming; over 50 is very low, built around a large pad and full-arm movement.

Does polling rate affect the turn?

No. Polling rate governs how often the mouse reports movement, not how many degrees a single count produces.

Worked example

A typical CS2 setup

Input: 800 DPI, sensitivity 1.0

Output: eDPI 800, a full turn in 51.95 cm

Note: Half a metre per turn is low sens: the movement comes from the shoulder rather than the wrist. It needs a big pad and repays with noticeably better precision at range.
