Garment measurements are not baby measurements
The numbers in the diagram measure the pajamas, not your baby. Each garment is laid flat on a table and measured point to point, in inches.
Your baby’s length is measured on your baby, crown to heel. The garment’s total length runs from the back of the neck to the end of the foot. The two numbers will never match, and they are not meant to.
Chest, waist and hip are measured across the garment laid flat. The knit has 4-way stretch, so the garment moves with your baby.
Every measurement, every size
Pick a measurement and a size. The tables show how each size compares with the next.

What this tool can and can’t tell you
- It checks your numbers against the same published size chart you see on every product page. Nothing more.
- It does not predict fit. It does not know your baby’s build, diaper or how fast they are growing.
- When more than one size includes your baby, both are listed. Use the garment measurements to compare.
- Each measurement has a tolerance of ±0.39 in (±0.2 in for body length and foot), so small differences between pairs are normal.
- Sizes 12-18M and up are snug-fitting sleepwear. Choose the size that fits snugly now.
How every pair is built
One 2-way zipper
Unzip from the bottom for a diaper change. The top stays closed, so a sleeping baby stays dressed.
Footed or footless
Every pair converts. Fold the foot cuffs down to cover the feet, or fold them back for bare toes.
Fold-over mitts
Every pair has hand cuffs that fold over little hands, then fold back when you want fingers free.
Grips on the soles
Non-slip grips sit on the soles only. You get them when the feet are covered.
