How This Works

This calculator determines your ideal pillow height (loft) based on three factors:

  • Sleep Position: Side sleepers need higher loft to fill the shoulder gap. Stomach sleepers need the lowest loft.
  • Shoulder Width: Broader shoulders require a taller pillow to keep the spine aligned while side sleeping.
  • Mattress Firmness: Softer mattresses allow your body to sink in deeper, reducing the gap and requiring a slightly thinner pillow.
