Romper Size Guide

Find the right fit

Use this romper size guide to choose the best size for your little one — with less guesswork. If your baby is between sizes, think about how you'd like the romper to fit: snug and neat, or with a little room to grow.

How to measure

Lay your baby flat or stand them straight. Use a soft tape measure to check their chest (around the fullest part), waist (the narrowest part of their tummy), and hips (the widest part). Keep the tape level and gently close to the body — not tight.

Size tips

Romper fits can vary by style, fabric, and stretch. If the design has a fitted waist or short leg length, sizing up may give extra comfort and wiggle room.
