What Is the Best Pillow for Broad Shoulders?
A pillow for broad shoulders usually needs more height for side sleepers, because the shoulder widens the gap between your head and the mattress. Shoulder width is only one input, so the right height comes from a measurement, not a guess.
Key takeaways
- Side sleepers with broad shoulders usually need a higher pillow than narrow-shouldered sleepers. Back and stomach sleepers depend less on shoulder width.
- Neck size, sleeping position and mattress firmness also change the answer. Weight does too, because a heavier body sinks deeper into the mattress.
- A Pillowise fitting at a provider near you is free. You can also exchange or return the pillow within the guarantee window.
Why do broad shoulders change the pillow you need?
On your side, the shoulder is the widest point between your head and the mattress. The pillow has to fill that gap. If it is too low, your neck tilts toward the mattress. If it is too high, it tilts away. Either way, the position is held for hours.

A small pilot EMG study of 15 adults found the lowest neck and shoulder muscle activity when pillow height matched shoulder width (Jiao et al., 2025). The sample was small and mostly healthy, so it shows an association, not a cure. We cover it in more detail in side sleeping, shoulder width and pillow height.
Is shoulder width the only thing that matters?
No. Pillowise combines five factors:
- Shoulder width
- Neck circumference
- Neck height
- Sleeping position (the position in which you fall asleep)
- Mattress firmness (soft, medium or firm)
A soft mattress, including many memory foam and hybrid models, lets a broad shoulder sink in, which can lower the height you need. Two people with very different bodies can end up with the same size. Not sure whether your current pillow is off? See how to tell if your pillow is the wrong height.
When will a pillow not help?
A fitted pillow is an adjunct to care, not a treatment. If you have numbness, tingling in your arm, or neck or shoulder pain that does not settle, see your own provider first.
How does Pillowise approach broad shoulders?
The Pillowise algorithm picks one of 7 sizes from your three measurements, plus sleeping position and mattress firmness. It indicates the right size for about 95% of people. Your provider checks how you lie on the pillow and adjusts if needed. The standard pillow measures 22 x 14 in and has a core of Dutch memory foam.
After giving the pillow 7-10 days to adjust, you can exchange it for another size or return it for a refund within 30 days of purchase. Return shipping is paid by the customer, and shipping charges are not refunded.
Find a provider near you
Pillowise is sold only through chiropractors, physical therapists and licensed massage therapists. The measurement is free at every provider. If you want to use an FSA or HSA, ask your plan administrator. You can also try the pillow height calculator, but a second person measuring you gives the best result.
