Gap Size Charts

Industry standard for baby apparel is to use age as the size, but it is important to measure your child as it is possible to have an older child that still needs a smaller size, or conversely a younger child that needs to size up. For example, a baby that is 14 months may still be wearing size 6-12 months given her measurements. If when measuring your child falls into two different sizes between weight and length (i.e. 24 lbs and 32") then it is best to size up to ensure a better fit.

Note apparel in sizes up to 2 years accommodates extra room for a diaper. Measurements up to 2 years below are represented with a diaper on.
