What is a Mouse DPI Test?

DPI stands for Dots Per Inch. It measures how many pixels your cursor moves for each physical inch you move your mouse. Our test lets you measure your actual DPI by dragging a known physical distance and counting the pixels traveled.

What DPI Should You Use?

  • FPS gaming: 400-800 DPI with low in-game sensitivity for maximum precision.
  • MOBA / RTS: 800-1600 DPI for quick cursor traversal across large screens.
  • Design work: 1000-1600 DPI for a balance of speed and fine control.
  • Desktop use: 1200-2400 DPI for comfortable daily navigation.

Why Test Your Input Devices?

Test your devices when you notice inconsistent clicking, unexpected double-clicks, cursor drift, or scroll wheel skipping. Regular testing also helps track hardware degradation over time.
