Size chart
Choose the size by your baby's height first. Weight and chest are a helpful double check.

Measurements are body measurements, not garment measurements, and are approximate. Every baby grows differently.

How to measure
Height
Lay your baby flat on their back, legs gently straight. Measure from the top of the head to the heel.
Chest
Wrap the tape around the fullest part of the chest, just under the arms. Keep it snug but not tight.
Compare
Match the height to the chart. If the chest or weight points to a different size, choose the larger one.
Fit tips
- Between two sizes? We recommend sizing up. Babies grow fast and a little room means more wear.
- Layering for cold weather? Choose the next size up to fit comfortably over a bodysuit.
- Gifting? Size up for a longer wear, especially for newborn and 3–6 month sizes.
- Not the right fit? You have 30 days to start a return or exchange from our returns portal.
