I have been told to sleep on my side
The reverse of the same arithmetic, and the more uncomfortable direction. Your shoulder now has to be accommodated, so the gap between your head and the mattress is suddenly much larger. A back sleeper's pillow is typically far too flat for it, which drops your head toward the mattress and loads the bottom shoulder and the ear.
This one is not a pillow question alone. The instruction and its reasons belong to whoever gave them. This page covers only the height consequence.
What the pillow has to do
- loft in measured range — Pillow loft within the range your own measurement implies. This is first for every constraint in this cluster, because no surface is soft enough to rescue a pillow your head has already flattened.
- position tolerant support — Support that does not depend on hitting one exact spot, so rolling over does not mean re-finding a position in the dark.
How people ask this
- Switching to side sleeping pillow too flat
- New side sleeper neck pain
- Pillow height for someone who always slept on their back
