Dana Kirkwood

Dana Kirkwood builds and maintains the size charts on NoomReviews. Every chart here is put together the same way: pull the official sizing from each major brand, check it against the governing body rule where one exists — Little League and USA Baseball for bats, the USGA for junior golf clubs, ASTM F1447 for bike helmets — then publish the range instead of a single number, because brands disagree more often than parents expect. Each chart carries the date it was last verified and the sources behind it. Where a measurement has to be taken at home, the steps are written out so you can do it with a tape measure and a doorframe. NoomReviews covers youth sports and outdoor equipment and kids apparel — what to buy for a child, and what size to get.
