Pillow Loft Chart by Sleeping Position

Widely used guidance puts side sleepers at 5 to 7 inches of loft, adjusted for shoulder width: broader shoulders (around 20 inches) typically add about 1 inch, narrower shoulders (around 16 inches) typically subtract about 1 inch. This is general comfort guidance, not a measurement or medical advice, since side sleeping puts the shoulder directly under the head and the pillow needs to fill that gap to keep the neck level.

Widely used guidance puts stomach sleepers at 2 to 3 inches of loft, the lowest of any position, since lying face down leaves almost no gap between the mattress and the head to fill. A higher pillow in this position tends to tilt the head at an angle rather than keep it level. This is general comfort guidance about preference, not medical advice.

For side sleepers, yes, according to widely repeated guidance. A broader shoulder, around 20 inches across, typically needs about 1 inch more loft than the base 5 to 7 inch range to keep filling the gap between mattress and head. A narrower shoulder, around 16 inches, typically needs about 1 inch less. Back and stomach sleepers are not affected the same way, since the shoulder is not under the head in those positions.

Pillow loft is the height of a pillow once it is compressed under the weight of a resting head, not its uncompressed height in the package. It is the figure that determines whether a pillow fills the gap between the mattress and the head correctly for a given sleep position. A pillow marketed as "high loft" without a number should still be checked against the ranges for your own sleep position.

Widely used guidance puts combination sleepers, who shift between back, side and stomach through the night, at 4 to 6 inches of loft, a middle ground between the lower 2 to 3 inch stomach range and the higher 5 to 7 inch side range. An adjustable loft pillow, where fill can be added or removed, is often a practical way to compromise across positions rather than settling on one fixed height.

An adjustable loft pillow is filled with shredded material, most often memory foam, that can be added or removed through a zippered opening to raise or lower the pillow's compressed height. It lets one sleeper dial in a personal loft rather than committing to a single fixed height, and it is a practical way to test different loft ranges without buying several pillows.
