eDPI Calculator
eDPI — effective DPI — is mouse DPI × in-game sensitivity: the number that lets gamers compare true sens regardless of hardware. Enter yours to get eDPI, cm per 360°, and a DPI conversion.
Example: with Mouse DPI 800 · In-game sensitivity 0.5 · Game (for the cm/360 row) Valorant · Convert to a new DPI 1600 → Your eDPI: 400.

Check it outWhat is eDPI and how do you calculate it?
eDPI = mouse DPI × in-game sensitivity. The default here is 800 DPI × 0.5 sens = 400 eDPI. Because the two factors multiply, wildly different setups can aim identically: 400 DPI at sens 1.0 and 1,600 DPI at sens 0.25 are both 400 eDPI and feel exactly the same. That is why players quote eDPI instead of raw sensitivity when comparing settings. To move to a new DPI without changing your aim, divide: 400 eDPI ÷ 1,600 DPI = sens 0.25.
One warning: eDPI only compares within the same game. Each title converts mouse counts to degrees with its own yaw constant (Valorant 0.07°, CS2 and Apex 0.022°, Overwatch 2 0.0066° per count), so 400 eDPI is a nimble 32.7 cm-per-360 in Valorant but a huge 104 cm in CS2. Across games, match the cm/360 row instead. For reference, commonly cited pro ranges sit roughly at 150–400 eDPI in Valorant and 600–1,200 in CS2.
How it’s calculated
eDPI = mouse DPI × in-game sensitivity (rounded to 0.1). Equivalent sensitivity at a new DPI = eDPI ÷ new DPI, which preserves aim exactly within the same game. The cm-per-360° row uses each game's mouse yaw constant — degrees turned per mouse count at sens 1 (Valorant 0.07°, CS2/CS:GO/Apex 0.022°, Overwatch 2 0.0066°): cm/360 = 360 × 2.54 ÷ (DPI × sens × yaw).

Common mistakes
- Comparing eDPI across games — Valorant's yaw (0.07°/count) is about 3.18× CS2's (0.022°), so 400 eDPI in Valorant turns like roughly 1,273 eDPI in CS2. Match cm/360 instead.
- Changing DPI without rescaling sens — moving 800 → 1,600 DPI doubles your eDPI unless you halve the in-game sensitivity.
- Copying a pro's sensitivity but not their DPI — sens alone means nothing; only the DPI × sens product transfers.
Frequently asked questions
What is eDPI?
Effective DPI: your mouse DPI multiplied by in-game sensitivity. It is the single number that describes true sensitivity, so 400 DPI at sens 2 and 1,600 DPI at sens 0.5 aim identically — both are 800 eDPI.
How do I calculate eDPI?
Multiply mouse DPI by in-game sensitivity: 800 × 0.5 = 400 eDPI. To keep the same feel at a new DPI, divide your eDPI by it: 400 ÷ 1,600 = sens 0.25.
What is a good eDPI for Valorant?
Commonly cited pro settings cluster roughly between 150 and 400 eDPI. At 280 eDPI a full 360° turn takes about 46.7 cm of pad; start mid-range and adjust for your pad size and role.
Is higher or lower eDPI better?
Neither is objectively better. Lower eDPI favors precise micro-adjustments at the cost of bigger arm movements; higher eDPI turns faster for close-range tracking. Consistency beats chasing a number.
Does eDPI transfer between games?
No — each game has its own yaw constant, so the same eDPI turns different amounts. 400 eDPI is 32.7 cm per 360° in Valorant but about 104 cm in CS2; convert by matching cm/360.
