Lower sensitivity requires more space
At lower sensitivity, the same 180° turn requires more physical hand movement, so a larger mousepad can help. This tool estimates usable horizontal width and does not account for keyboard overlap, sensor lift-off or arm movement angle.
Suggested width = cm/360 ÷ 2 × 1.25
If your available mousepad is smaller, a turn may still be possible by lifting and repositioning the mouse. The calculator is not a shopping recommendation.
