Hatch Size Guide
Finding your perfect fit matters — especially when your body is changing through pregnancy, postpartum, and beyond. Below you’ll find the Hatch size guide to help you choose confidently, without second-guessing.
How does Hatch sizing run?
Hatch is a US maternity brand, and most styles are designed to fit true to your pre-pregnancy size. Pieces are thoughtfully cut to allow room for a growing bump, with flexible fabrics and considered proportions that support you as your body changes.
If you’re between sizes, in your third trimester, or prefer a more relaxed fit, you may feel more comfortable sizing up — particularly in more structured styles.

[Tip: Your pre-pregnancy size is the best starting point to find your size at HATCH (after all, no one knows your body better than you). Size up for a more relaxed fit or down for a more bodycon look. If you're 5'2'' or shorter our Petite (P) sizes are for you - above 5'2'', choose O/S.]
How to Measure Yourself in Hatch
For the most accurate fit, use a soft tape measure and take measurements directly against your body:
-
Bust: Measure around the fullest part of your bust
-
Waist: Measure around your natural waist (the narrowest part of your torso)
-
Hips: Measure around the fullest part of your hips
If your bust or hip size puts you between two sizes we recommend you go with the larger of the two - so if your bust measurement puts you in a size 2 but your hips are more in line with a size 0, go with the size 2.
