Find your pillow height in 60 seconds.
Pillow height is not one-size-fits-all. It depends on how you sleep, how broad your shoulders are and how far your mattress lets you sink. Answer four quick questions for a starting range in inches.

Start with Amity's higher, side-sleeping side
Side sleeping needs the most height, because your shoulder lifts your head off the mattress. Your estimate sits close to Amity's higher 4.5″ side, which has a raised edge for your neck and a softer cradle for your head.
Your target is lower than Amity's higher, side-sleeping side
A slimmer frame or a soft mattress means you need less height. Amity's 3.5″ side may suit you if you like firm, shaped support. If you prefer a softer feel, an adjustable-fill pillow lets you take fill out until it is level.
Your target is taller than Amity's higher, side-sleeping side
Broad shoulders on a firm mattress can need more than 5″ of height. Amity's higher side may feel a little low for you. An adjustable-fill pillow lets you add fill until your head is level.
Start with Amity's lower, back-sleeping side
Back sleeping needs less height than side sleeping. The lower 3.5″ side supports the curve of your neck without pushing your chin toward your chest.
You switch positions, so one height rarely works
This is what two heights are for: 3.5″ for back sleeping and 4.5″ for side sleeping. Start on the side that matches how you usually fall asleep. If you mostly wake on your side, give the 4.5″ side a week, then compare it with the 3.5″ side.
Amity is probably too tall for you
Stomach sleeping usually needs a very low, soft pillow, or none, so your neck is not turned and bent upward. A contoured pillow keeps your head raised. An adjustable-fill pillow lets you remove most of the fill.
About your current pillow: Loose fiber fill tends to flatten where your head presses longest. Memory foam holds its shape better; Amity uses dual-density memory foam, firmer at the support edges and softer in the head cradle.
About your current pillow: If your current pillow feels tall, try a lower height first. Back sleepers usually need less than side sleepers.
About your current pillow: An arm under the pillow often means the pillow is too low for your shoulder. Get the height right first and keep your lower arm in front of you. If your arm regularly goes numb or tingles, talk to a clinician.
About your current pillow: Stacked or folded pillows slide apart and flatten unevenly. One pillow at the right height is easier to keep consistent.
About your current pillow: No pillow can cool you down, but airflow helps. Amity has breathable mesh sides; an open honeycomb gel pillow is airier still.
About your current pillow: If your pillow already feels right, keep it. Use the range as a check.
How the estimate works
Your pillow's job is to fill the space between your head and the mattress, so your head sits roughly in line with your spine. That space changes with position. On your side, your shoulder props you up, so the gap is widest. On your back, it is smaller. On your stomach, it is smallest.
| Position | Starting range | What moves it |
|---|---|---|
| Side | About 3½–5½″ | Broader shoulders need more; a softer mattress needs less |
| Back | About 2¾–4″ | A softer mattress needs slightly less |
| Stomach | About 1½–2½″, or none | Lower is usually more comfortable |
These are rule-of-thumb starting points, not medical guidance. Your comfort over several nights is the real test. For a deeper explanation, read our side-sleeper pillow height guide or the pillow size chart.
Check your fit tonight
- Lie down as usualUse your normal mattress and position. Measure on the bed you sleep on, not on the floor.
- Look at the lineAsk someone to take a photo from the foot of the bed, or use a mirror. On your side, your nose, chin and breastbone should roughly line up. On your back, your chin should not tuck toward your chest or tip back.
- Give it a weekA contoured shape feels different at first. If it still feels wrong after about a week, try the other side or a different height.

Questions
What pillow height do side sleepers need?
Most side sleepers need about 3½ to 5½ inches, depending on shoulder width and how much the mattress lets the shoulder sink. Broad shoulders on a firm mattress sit at the top of that range.
Is a 4.5-inch pillow too high?
For many side sleepers, no. It can be too high for back sleepers and is usually too high for stomach sleepers. That is why Amity also has a 3.5-inch side.
What if I switch positions during the night?
Start on the side that matches how you fall asleep. If you mostly wake up on your side, try the higher side for a week and then compare it with the lower side.
Can the right pillow fix neck pain?
A pillow can make a position more comfortable, but it is not a treatment. If you have persistent neck pain, numbness or pain after an injury, see a clinician.
Do I need to measure my shoulders?
No. Picking the closest frame is enough for a starting range. If you want to measure, check the distance from the side of your neck to the outer edge of your shoulder.
