What is a size 6?How girls' and boys' size 6 compare across 43 kids' brands

A size 6 isn't the same everywhere — and unlike toddler sizes, most brands cut it differently for girls and boys. Here's where the brands on Little & Youth land with each, taken straight from every brand's own published size chart.

The short answer: At a size 6, a typical girls' fit lands about 44–46½" tall and a typical boys' fit about 44–46½". Many brands publish one unisex size 6 that covers both, but where a brand splits them the girls' and boys' cuts can differ by an inch or more. All told, the same "size 6" is used for kids from 42 to 49½ inches tall across brands — so the label alone can't tell you the fit.

Common questions about size 6

Does a size 6 run big or small?

It depends on the brand and whether it's cut for a girl or a boy. A girls' size 6 runs bigger at Polo Ralph Lauren Kids, Brooks Brothers Kids, and Vineyard Vines Kids and smaller at Converse Kids, H&M Kids, and JCPenney Thereabouts. A boys' size 6 runs bigger at Target Cat & Jack, Polo Ralph Lauren Kids, and Garnet Hill and smaller at Converse Kids, Brooks Brothers Kids, and H&M Kids. Most brands land in between.

Is a girls' size 6 the same as a boys' size 6?

Not always. Many brands publish one unisex size 6, but brands that split them cut the two a little differently — a girls' 6 typically fits about 44–46½" and a boys' 6 about 44–46½". If a brand offers both, check the one that matches your child.

What height is a size 6 for?

At most brands, a size 6 fits a child roughly 44–46½" (girls) or 44–46½" (boys) tall. Because height is what actually determines fit, it's worth checking your child's height against the specific brand's size 6 rather than going by age.

What age is a size 6 for?

A size 6 is designed with 6-year-olds in mind, but age is only a rough guide. Because it's built around height and build, plenty of kids wear a size 6 a year earlier or later than the label suggests — checking height against a specific brand's chart is far more reliable.

What size comes after size 6?

After a size 6, most brands move to a size 7. 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 6 left off.
