Calculate effective sensitivity from DPI and in-game sensitivity. Compare setups and find your ideal DPI and sens combination.
Your actual mouse sensitivity is determined by two settings: hardware DPI and in-game sensitivity. Many DPI and sensitivity combinations produce identical results — 400 DPI at 2.0 sens feels exactly like 800 DPI at 1.0 sens.
This calculator shows you the effective sensitivity (eDPI) from your DPI and sens combination, plus the equivalent cm/360 measurement. Use it to compare your setup with pros, find equivalent combinations at different DPI levels, or troubleshoot why your aim feels off.
DPI (dots per inch) is your mouse hardware setting. In-game sensitivity is a multiplier applied on top. The product of both determines your actual aim speed.
Gamers, streamers, and content creators benefit from precise dpi to in-game sensitivity 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 dpi to in-game sensitivity 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.

Knowing your eDPI lets you meaningfully compare sensitivity with other players, regardless of their DPI setting. It's the common unit that makes sensitivity discussions useful and ensures you're using settings that match your style. 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 cm/360 = (360 / (DPI × sensitivity × yaw)) × 2.54
Result: eDPI: 800 | cm/360: 52.05 cm
eDPI = 800 × 1.0 = 800. cm/360 = (360 / (800 × 1.0 × 0.022)) × 2.54 = 52.05 cm. This is equivalent to 400 DPI at 2.0 sens (also eDPI 800), or 1600 DPI at 0.5 sens.
DPI and in-game sensitivity are two multipliers in the same chain. DPI sets how many counts your mouse reports per inch of physical movement. In-game sensitivity multiplies those counts into camera rotation. Both together determine your effective aim speed.
Without eDPI, sensitivity discussions are meaningless. Saying "I use 2.0 sens" tells you nothing without knowing the DPI. eDPI standardizes these conversations and enables accurate comparison between setups.
Find a comfortable eDPI by starting with a mid-range value for your game, then adjusting by 5-10% increments. Play for at least 50 games before making another change. Rapid sensitivity changes prevent muscle memory from forming.
eDPI (effective DPI) is the product of your hardware DPI and in-game sensitivity. It represents your true mouse speed. Two players with different DPI/sens combos but the same eDPI will have identical mouse movement.
Most competitive players use 400 or 800 DPI. Higher DPI (1600+) can reduce pixel skipping on high-resolution monitors. The specific DPI doesn't matter as much as the resulting eDPI.
At low DPI, the mouse reports large jumps between positions, potentially skipping pixels on screen. Higher DPI reduces these jumps, providing smoother movement. At 4K resolution, 800+ DPI is recommended.
Higher polling rate (not DPI) affects input responsiveness. DPI mainly affects granularity of movement. Both contribute to overall mouse performance but DPI alone doesn't add input lag.
Changing either achieves the same eDPI. However, keeping DPI constant and adjusting in-game sens is simpler for game-to-game consistency. Change DPI only if you need to address pixel skipping.
In CS2, most pros use eDPI 600-1200 (median ~860). In Valorant, the range is 200-400 (different sens scale). In Overwatch, eDPI varies by role: 3000-5000 for DPS, 5000-8000 for tanks. Always consider the game's sensitivity scale.
