Pillow Height Guide: How Tall Should Your Pillow Be?
The right pillow height depends on two measurements, not one: side sleepers need 4 to 6 inches of compressed loft — 5 to 7 with broad shoulders — back sleepers 3 to 5, stomach sleepers under 3, then adjust about an inch for your mattress: subtract on a soft mattress that lets the shoulder sink, add on a firm one that holds it up. The full matrix is below.

Pillow Height Guide: How Tall Should Your Pillow Be?
The right pillow height depends on two measurements, not one: side sleepers need 4 to 6 inches of compressed loft — 5 to 7 with broad shoulders — back sleepers 3 to 5, stomach sleepers under 3, then adjust about an inch for your mattress: subtract on a soft mattress that lets the shoulder sink, add on a firm one that holds it up. The full matrix is below.
Quick Answer: Four Rules Before the Matrix
Measure compressed loft, not shelf height — what matters is the height of the pillow under the actual weight of your head, hours into the night. A pillow that fluffs to 7 inches on the bed but flattens to 3 under your head is a 3-inch pillow. All the numbers in this guide are compressed loft.
Your position sets the baseline — the pillow's only job is to fill the gap between your head and the mattress so the spine stays in one line. Side sleeping creates the biggest gap (the shoulder), back sleeping a moderate one, stomach sleeping almost none.
Your shoulders set the adjustment — broader shoulders widen the head-to-mattress gap, so side sleepers with broad shoulders need 5 to 7 inches and a firm fill. One in four people in our study has broad shoulders, and most of them have never bought a pillow tall enough for it.
Your mattress moves the number about an inch — a softer mattress lets the shoulder sink in, shrinking the gap: subtract roughly an inch. A firmer mattress holds the shoulder up, widening it: add roughly an inch. Same body, same position, different pillow.

The Pillow Height Matrix
Find your row (sleep position), then your column (shoulder width). All heights are compressed loft — the height under your head, not on the shelf. Then apply the mattress adjustment below.
Sleep position | Narrow–average shoulders | Broad shoulders |
|---|---|---|
Side | 4–6 in · medium-firm | 5–7 in · firm |
Back | 3–5 in · medium | 3–5 in · medium — shoulder width matters least on the back |
Stomach | Under 3 in · soft | Under 3 in · soft — width does not raise the ceiling face-down |
Combination | 4–5 in · medium, responsive fill that re-lofts as you turn | 5–6 in · medium-firm, responsive |

Step Two: Adjust for Your Mattress
The mattress decides how far your shoulder sinks, which changes the gap your pillow has to fill. This is why the same pillow can feel perfect on one bed and wrong in a hotel.
Your mattress | What happens to your shoulder | Pillow height adjustment |
|---|---|---|
Softer / plush | The shoulder sinks into the mattress, shrinking the head-to-mattress gap | Subtract about 1 inch from your matrix number |
Medium | Moderate sink — the assumption the matrix is built on | Use the matrix number as-is |
Firmer | The shoulder stays on top of the mattress, widening the gap | Add about 1 inch to your matrix number |

Check Your Current Pillow in Under a Minute
Before buying anything, run these three checks on the pillow you already own. Two are about height, one is about whether the pillow can still hold any height at all.
1. The Alignment Test
Lying on your side, the pillow should hold your nose, chin, and breastbone in a straight line. On your back, your chin should neither tilt up nor tuck down. A stretch on the underside of the neck means the pillow is too high; the head tipping toward the mattress means too low.
2. The Photo Check
Have someone photograph you from behind while you lie on your side in your normal position. The line of your spine through your neck should be level with the mattress — not bending up over a too-tall pillow or sagging down into a flat one. Ten seconds, and it removes all guesswork.
3. The Fold Test
Fold the pillow in half and let go. Healthy fill springs back to full loft immediately; a pillow that stays folded has lost its structure and cannot hold any target height, no matter what the matrix says. If yours fails this, fix the pillow before fine-tuning the number.

Two Pillows That Hold Their Number
A height chart only helps if the pillow still measures the same at 3 a.m. Both come in soft, medium, and firm, backed by Lincove's 60-day trial with a free firmness exchange — so you can dial in your matrix number at home.
THE LOFT CHAMPION
Signature™ Canadian Down Pillow
800 fill power Hutterite Canadian down in a 500 thread count cotton sateen shell with double-stitched edges. The highest loft we offer and the slowest to compress — in firm, it is the pillow built for the 5-to-7-inch rows of the matrix: side sleepers, broad shoulders, firm mattresses.
THE MIDDLE ROWS
Cloud™ Canadian Down Pillow
625 fill power Canadian down with an antimicrobial cotton sateen shell. In medium it sits squarely in the 3-to-5-inch back-sleeper and 4-to-5-inch combination rows, and the down re-lofts the moment you turn — so the height you chose is the height you keep, position to position.
