Many people now know that a bad pillow can cause problems. But what is often underestimated is that not only the material matters – the height of your pillow is at least as crucial for your night's rest.
The height of your pillow determines whether your neck remains in a neutral position while you sleep. This means your head is aligned with your spine. This is precisely what is needed to allow muscles to relax and enable recovery.
A pillow can be ever so luxurious, but if the height is incorrect, your body will continue to compensate.
What happens if the height isn't right?
-
If your pillow is too low, your head sinks, and your neck and shoulders are strained.
-
If your pillow is too high, your neck is pushed out of alignment, leading to overuse.
In both cases, muscles remain active at night when they should be relaxing. The result is often restless sleep and discomfort upon waking.
What does the correct pillow height depend on?
The correct height is not a coincidence or a matter of taste. It is primarily determined by:
-
your sleeping position (back, side, or stomach)
-
your shoulder width and physique
-
the firmness of your mattress
That's why a single standard height is rarely suitable for everyone.
Which height suits your body and preferred sleeping position?
8–10 cm support
Suitable for back sleepers, stomach sleepers, and people with narrow shoulders.
This lower height helps the neck remain in a relaxed, neutral position and prevents overextension.
10–12 cm support
Suitable for side sleepers with an average physique.
This is the most popular height and provides stable alignment of the head, neck, and spine.
12–14 cm support
Suitable for side sleepers with broad shoulders or a broader physique, often men.
Extra height prevents the head from sinking sideways and helps reduce tension in the neck and shoulders.
Why stability is at least as important as height
The correct height only works if the support remains stable throughout the night.
When a pillow sags, shifts, or constantly needs readjusting, the alignment is still disturbed, and the body has to keep correcting itself.
Therefore, it is important that a pillow:
-
retains its shape
-
provides even counter-pressure
-
does not move or sink when turning
Only then can your neck truly relax.
What about stomach sleepers?
From an ergonomic point of view, sleeping on your stomach is not ideal because the neck is in rotation for a long time, and the lower back is subjected to extra strain. This can contribute to neck and tension complaints. At the same time, sleeping posture is often a habit—and habits can be well managed and adjusted.
Do you want to switch from sleeping on your stomach to a more supportive sleeping position? These tips will help:
1. Make side sleeping more appealing
Use a good supportive pillow and, if necessary, place an extra pillow against your chest or between your knees. This provides stability and prevents you from unconsciously rolling back onto your stomach.
2. Use a simple physical reminder
Before going to bed, place a tennis ball in a sock and loosely place it on your stomach or lightly attach it to your pajamas. As soon as you turn onto your stomach in your sleep, this will give a subtle stimulus that will automatically make you turn back without waking up.
3. Train your new sleeping posture during the day
In the evening, before going to bed, take a short time to relax while lying on your side or back. The body remembers this posture and takes it into the night more easily.
Are you (still) sleeping on your stomach and want to use a pillow?
Then always choose the lowest support (8–10 cm), so that the strain on the neck and spine remains as limited as possible.
The correct pillow height is not a detail, but a prerequisite for relaxation and recovery.
When both height and stability are correct, your body no longer has to compensate at night, and you'll notice that when you wake up.
