How does the online DPI checker measure mouse DPI?

By moving your mouse across a calibrated physical distance (e.g. exactly 1 inch or 2.54 cm), the tool records raw hardware movement pixel events and calculates: Measured DPI = Registered Counts / Physical Inches Moved.

What is eDPI in gaming?

eDPI (effective DPI) is your hardware mouse DPI multiplied by your in-game sensitivity (eDPI = DPI × In-Game Sensitivity), allowing players to compare true sensitivities across different hardware setups.
