DPI is the most advertised mouse spec and one of the most misunderstood. Here’s how it works together with in-game sensitivity, and how to settle on a setting.
What DPI actually is
DPI (dots per inch) is how many counts the sensor reports for each inch you move the mouse. At 800 DPI, one inch of movement sends 800 counts. At 1600 DPI, the same inch sends 1600, so the cursor moves twice as far.
That’s all it does. A 26,000 DPI rating doesn’t make a mouse more accurate. Nobody games at that setting.
DPI × in-game sensitivity = what you feel
Your actual turning speed comes from both numbers. 800 DPI at 1.0 sensitivity feels the same as 1600 DPI at 0.5 sensitivity in most games. That’s why players compare eDPI (DPI × sensitivity), or better, cm/360: how far you move the mouse to turn a full circle.
Practical settings
- Pick 800 or 1600 DPI as your base. Both are well within the range where every modern gaming sensor is accurate, and they keep the desktop cursor usable.
- Turn off Windows “Enhance pointer precision.” It’s mouse acceleration, and it makes the same physical movement produce different results depending on speed.
- Set in-game sensitivity by feel: in a practice mode, you should be able to turn 180° comfortably in one sweep and still make small corrections on a target.
Typical ranges by genre
| Game type | Common cm/360 range |
|---|---|
| Tactical FPS (Valorant, CS2) | Lower sensitivity, roughly 30–60cm |
| Fast arena / battle royale | Medium, roughly 20–40cm |
| MOBA / RTS | Higher, often cursor-based |
These are only starting points. Arm aimers tend to go lower, wrist aimers higher. Low sensitivities need more desk space and a bigger mouse pad.
Keep it consistent
Once you find a setting you like, use the same cm/360 across games. Sensitivity converter sites can translate it between titles, so your muscle memory carries over.
