It depends on the brand and whether it's cut for a girl or a boy. A girls' size 20 runs bigger at French Toast, Macy's Epic Threads, and Lands' End Kids and smaller at Justice, Walmart Wonder Nation, and Lands' End Kids. A boys' size 20 runs bigger at Lee Jeans, Lands' End Kids, and Calvin Klein Kids and smaller at Original Penguin Junior, Converse Kids, and JCPenney Thereabouts. Most brands land in between.
Not always. Many brands publish one unisex size 20, but brands that split them cut the two a little differently — a girls' 20 typically fits about 60–62" and a boys' 20 about 67–69". If a brand offers both, check the one that matches your child.
At most brands, a size 20 fits a child roughly 60–62" (girls) or 67–69" (boys) tall. Because height is what actually determines fit, it's worth checking your child's height against the specific brand's size 20 rather than going by age.
A size 20 is designed with older kids and teens in mind, but age is only a rough guide. Because it's built around height and build, plenty of kids wear a size 20 a year earlier or later than the label suggests — checking height against a specific brand's chart is far more reliable.
After a size 20, most brands move to adult XS / juniors sizing. Sizing can shift noticeably at that step, so it's worth checking the next size's height range rather than assuming it picks up where size 20 left off.
Enter your child's measurements once and Little & Youth shows the size to buy across all 90+ brands on the site — girls' or boys', size 20 or otherwise — each pulled from that brand's own published chart.
