Calculate your effective DPI (eDPI) for any FPS game. Enter DPI and in-game sensitivity to find your true mouse speed and cm/360.
eDPI (effective dots per inch) is the universal way to express mouse sensitivity in FPS games. It combines your hardware DPI and in-game sensitivity into a single number that represents your actual mouse speed.
Two players using different DPI and sensitivity settings can have identical aim speed if their eDPI matches. For example, 400 DPI × 2.0 sens = 800 eDPI is identical to 800 DPI × 1.0 sens = 800 eDPI.
This calculator computes your eDPI and translates it to cm/360 for a physical measurement of how far your mouse travels for a full in-game rotation.
Gamers, streamers, and content creators benefit from precise edpi data when optimizing their setup, planning purchases, or maximizing performance and value. Bookmark this tool and return whenever your hardware, games, or streaming requirements change.
From casual players to competitive esports enthusiasts, knowing your precise edpi numbers empowers smarter hardware investments, streaming decisions, and long-term upgrade planning. Adjust the inputs above to mirror your actual setup and discover optimizations you may have overlooked.

eDPI is the standard metric for comparing sensitivity settings. When someone shares their sensitivity, eDPI makes the comparison meaningful regardless of their DPI setting. Use it to match pro settings, compare with teammates, or fine-tune your own setup. Instant results let you compare different configurations and scenarios quickly, helping you get the best performance and value from your gaming budget.
eDPI = DPI × in_game_sensitivity
Result: eDPI: 1,200
eDPI = 800 × 1.5 = 1,200. In CS2, this translates to about 34.7 cm/360, which is on the faster end for tactical shooters but common in faster-paced games.
Before eDPI, sensitivity discussions were confusing. Players would share in-game sensitivity values without mentioning DPI, making comparisons impossible. eDPI solved this by providing a single number that captures actual mouse speed.
Start with the median eDPI for your game. Play 20-30 matches, noting if you consistently over-aim (eDPI too high) or under-aim (eDPI too low). Adjust by 5-10% and repeat. Converging on your ideal typically takes 1-2 weeks.
There's no correlation between eDPI and skill level. Top players span the full range. What matters is consistency — pick an eDPI and stick with it long enough to build muscle memory.
There's no single best eDPI. In CS2, pros average around 860 eDPI with a range of 400-1600. In Apex Legends, higher eDPI (1200-2400) is common. Find what's comfortable for your game and play style.
Lower eDPI gives more precision for micro-adjustments and flick shots. Higher eDPI allows faster turns and smoother tracking. Most competitive players use low-to-medium eDPI with a large mousepad.
Only if the games use the same yaw value. CS2 and Apex share yaw 0.022, so their eDPIs are directly comparable. Overwatch and Valorant use different yaw values and need conversion.
Low eDPI provides finer control over crosshair placement, which is critical in tactical shooters where single headshots matter. The tradeoff is needing larger mouse movements, which pros mitigate with proper arm-aim technique.
Pro eDPI is a useful starting point but not a rule. Pros have thousands of hours at their sensitivity. Start near the average for your game, then adjust based on comfort. Monitor size, mousepad size, and play style all factor in.
Adjust either DPI or in-game sensitivity. To maintain eDPI while changing DPI, divide the new DPI into the old eDPI for the new sens. Example: Moving from 400 DPI to 800 DPI at eDPI 800: new sens = 800/800 = 1.0.
