Frequently Asked Questions
What is mouse DPI (Dots Per Inch)? ↓
DPI (Dots Per Inch) measures the physical hardware sensitivity of your mouse sensor. A DPI of 800 means moving your mouse 1 physical inch across your mousepad moves the cursor 800 pixels on your screen.
How do I test my mouse DPI online? ↓
Use our interactive DPI analyzer below. Click the start marker, move your physical mouse exactly 1 inch (2.54 cm) to the right across your mousepad, and release. The tool counts the exact pixel displacement to calculate your mouse DPI.
What is the best mouse DPI for gaming? ↓
Most competitive FPS esports pros (Valorant, CS2) use 800 DPI or 1600 DPI combined with low in-game sensitivity. High DPI (1600+) reduces mouse sensor latency and smoothing, while 800 DPI provides comfortable desktop navigation.
What is eDPI (Effective DPI)? ↓
eDPI is calculated by multiplying your physical mouse DPI by your in-game sensitivity (e.g., 800 DPI × 0.35 Valorant Sens = 280 eDPI). It allows gamers to compare true sensitivity across different hardware.
