What is the ideal mouse pad size for low-DPI gaming?

45 cm (about 18 inches) is the sweet spot for low-DPI gaming at 400 or 800 DPI. This lets you do a full 360-degree turn without lifting the mouse, and most competitive shooters like CS, Valorant, and Overwatch work best around that width. Don’t go smaller than 450x400 mm (18x16 inches), or you’ll be constantly lifting the mouse.
