I have been compiling measurement charts for years trying to make sure I can properly estimate sizing for gifts, my own pattern creations, and of course my family. These charts estimate the measurements, and might lean towards the sturdier child since both my kids are in the 90 percentiles for height and weight. For the PDF file, follow this link.
I wish I could give credit where credit is due, but the measurements were compiled from a wide variety of sources and personal experience. Some numbers are averaged, or I selected from multiple options that which best fit my own kids. Certainly the Simplicity Creative Group, Ottobre Design, and assorted books and websites. As I recall them I will try to give them credit!
