View instructions on how to read and use Size Charts posted on the Baby Discovery website.
Size Estimates
The size charts below are average body measurements. They are a general guide to help you determine which size of clothing is right for your child.
Measure the child’s height and weight to determine their clothing size. If the child’s measurements fall within two different sizes on the chart below, please select the larger size to allow for additional growth.
Measurements for babies should be based more importantly on weight. Older children’s measurements should place more emphasis on height.
Size measurements are generally provided in the detail section of each clothing item. If information has not been provided on the website, please complete the Contact Us form and provide the SKU and size in order to obtain the measurements. Email inquiries are typically answered the same business day or within 1 - 2 business days. Email requests for information submitted on Friday will typically be answered the following Monday.
