Measure real mouse DPI from a controlled desk movement, compare repeated runs, and use the result for eDPI or game sensitivity tuning.
1 — Setup
Tip: Use a ruler on your desk. Mark start & end, then drag through the track area while pressing your mouse button. Each drag = one run. Up to 5 runs are averaged automatically.

Formula: eDPI = Mouse DPI × In-game Sensitivity
eDPI lets you compare sensitivity fairly across different DPI settings and games.
Pro Range Comparison
Your eDPI is highlighted in the table below.
| eDPI Range | Level | Common for |
|---|---|---|
| 200 – 400 | Ultra Low | Pro FPS (S1mple, sh1ro) |
| 400 – 800 | Low | Competitive FPS / Valorant pros |
| 800 – 1600 | Medium | General gaming, casual FPS |
| 1600 – 3200 | High | MOBA / RTS players |
| 3200+ | Very High | Office, design, casual |
Most pro FPS players use 200–800 eDPI for maximum precision.

Target Setup
new_sens = (400 × 2.0) / 800
New sensitivity — same muscle memory, different DPI
How It Works
The converter keeps your eDPI constant, so the same physical arm/wrist movement always moves your in-game view the same distance — even after you change DPI.
Example: 400 DPI at 2.0 sens → 800 DPI at 1.0 sens.
Both have eDPI = 800. Your aim feels identical.
When to use this:
• Switching to a new mouse with a different DPI
• Matching a pro player's feel at your DPI
• Cross-game consistency (same cm/360°)
Note: This keeps eDPI equal. In-game sens multipliers vary per game — verify the feel with the DPI Test tab after adjusting.
