1. Quick Answer
Pillow thickness for side sleeper (also known as “loft”) refers to the compressed height of a pillow during use. For side sleepers, the ideal thickness typically ranges from 4 to 6 inches, designed to fill the gap between the ear and the outer shoulder. While these pillows provide significant structural support for the head, their primary limitation is that no single height is universal; the “perfect” thickness depends entirely on an individual’s shoulder width and mattress firmness.
