Juniors' Clothing Size Conversion Chart (8-14 Years)
Between ages 8 and 14, children's sizes reach the bottom of the adult range, and that overlap causes most sizing confusion. US kids' sizes run 8, 10, 12, 14, 16, often labelled S to XL, and a US 14 to 16 corresponds to a women's XS or men's XS. Europe, Korea and Japan continue the height system: 128, 134, 140, 146, 152, 158, 164, 170 in Europe, and 130 to 170 in 10 cm steps in Korea and Japan.
Measure height, chest and waist, and check garment length. Growth spurts around age 11 to 13 can add 8 to 10 cm in a year, so buying to current height plus 5 cm is sensible. For teens over 150 cm, compare the kids' XL against adult XS in the same brand; the kids' version is usually cheaper and cut shorter through the body, while adult XS offers longer sleeves and inseam.
