eDPI Calculator

Two players with different mouse DPI and in-game sensitivity can have exactly the same aim feel. eDPI (effective DPI) puts them on one scale: DPI × sensitivity. This calculator works out your eDPI and the physical distance for a 360° turn, converts your sensitivity between popular games so your muscle memory carries over, and shows where you sit compared with typical settings.

What eDPI means

Your mouse’s DPI (dots per inch, also called CPI) is how many counts it reports per inch of movement. The game’s sensitivity multiplies those counts into turning. eDPI = DPI × in-game sensitivity, so 400 DPI at sensitivity 2.5 and 800 DPI at 1.25 both give an eDPI of 1,000 and feel the same in that game. Because every game converts counts into rotation differently, eDPI values are only comparable within one game.

cm/360: a universal measure

cm/360 is how far you move the mouse to turn a full circle. It works across games: 360 ÷ (DPI × sensitivity × yaw) gives the counts per turn in inches of mouse travel, times 2.54 for centimetres. For CS2, yaw is 0.022° per count; for Valorant 0.07; for Overwatch 2 0.0066. A cm/360 of around 30–50 cm is common among players of tactical shooters, while faster-paced games often use lower values.

Worked example

The familiar shortcut “divide CS sensitivity by 3.18 for Valorant” comes from 0.07 ÷ 0.022 ≈ 3.18.

Choosing your sensitivity

• Lower sensitivity (higher cm/360) gives finer control for precise shots but needs more desk space and arm movement.
• Higher sensitivity turns faster with less movement but is harder to control for small adjustments.
• Pick one setting and keep it for weeks; constant changes stop muscle memory forming.
• Make sure your mouse pad is big enough for a comfortable 180° turn.
• Use the same DPI across games and adjust in-game sensitivity so cm/360 matches.

DPI tips

• Common DPI settings are 400, 800 and 1,600; higher DPI with lower sensitivity can reduce pixel skipping in some games.
• Turn off mouse acceleration (“enhance pointer precision” in Windows) for consistent aim.
• Use raw input where the game supports it.
• Check your mouse software — the actual DPI can differ slightly from the label.

Typical ranges

These are broad ranges seen among competitive players, not recommendations; comfort and play style matter more than copying anyone.

Finding your sensitivity

1. Start from a middle value — for example around 40 cm/360 for tactical shooters or 25–30 cm for faster games.
2. In a practice mode, flick to targets at different angles; if you overshoot often, lower the sensitivity; if you undershoot or run out of pad, raise it.
3. Adjust in small steps of about 5–10% and play several sessions before judging.
4. Once it feels right, write it down and stop changing it.
5. Match other games to the same cm/360 using the conversion table.

Why pros use low sensitivity

Many professional players of tactical shooters use relatively low sensitivity with large mouse pads, because small, precise adjustments matter more than fast turns when enemies appear in predictable places. In games with more vertical movement or close-range fights, higher sensitivity is common. There isn’t a single best value — it depends on your arm, desk, mouse and game.

Converting between games

To keep the same feel when you switch games, match cm/360 rather than the sensitivity number. The table in the calculator converts your current sensitivity into each game at the same DPI. Aim-down-sights and scope sensitivities have their own multipliers in each game, so fine-tune those separately after matching hip-fire.

Sensitivity cards pack

The optional pack includes printable sensitivity cards to keep your settings for each game, a practice log for aim training, and a mouse and pad setup checklist. The calculator above is free.
