Clothing Size Guide

Jan & Jul sizing for our kids’ clothing is based on age. However, each child is different in size and it is common to have a younger child that needs a bigger size or vice versa. For that reason, Jan & Jul provides height recommendations to ensure a better fit for each child. If your kids’ measurements fall into two different sizes, we recommend sizing up to make sure your child gets longer use out of the clothing. 

NOTE: Measurements provided for garments in size charts are the actual garment measurements – not the body measurements. The height is the suggested child height.
