Postpartum belly bands are usually sized like everything else in maternity — by pre-pregnancy dress size. The problem is your postpartum body doesn't match your pre-pregnancy size, and it keeps changing for weeks after birth. Sizing off an old number is how you end up with a band that doesn't fit by week three.
Measure where the band actually sits
Skip the dress size guesswork. Wrap a soft tape measure around your body at the belly button — that's where a postpartum band naturally sits, and it's the measurement that actually matters.
Between two sizes? Go up
Postpartum swelling goes down over the first several weeks, so a band that's slightly loose now will fit better — not worse — as you heal. A band that's snug on day one usually ends up too tight within a week or two.
Adjustable beats one-size
This is really the whole argument for adjustable sizing over a fixed band: your waist measurement in week two and your waist measurement in week ten are not the same number. A band with real adjustability — not just a little stretch — is the difference between something you wear for two weeks and something you wear for two months.
Our Back & Belly Band runs in three tiers — S/M, L/XL, 2XL/3XL — each with enough adjustable range to move with you through the recovery window, not just the first few days of it.
