Sleeper/Romper/Onesies Size-Chart
Choose the Section for Your Baby’s Style
The first section gives suggested body height and weight. The following sections list garment measurements for kimono onesies, sleepers and rompers. Choose the section named for your product, then compare the length and half-chest measurements in cm or inches.
Age labels are a starting point. Use the chart linked by the individual product; size labels and cuts can vary between styles. Measurements labelled “1/2 Chest” are half-width measurements, not full body chest circumference.
