Nike size chart

Nike’s own size charts cover men’s 3.5–22, women’s 3.5–22.5, unisex 3.5–22, toddler 1C–10C, little kid 8C–3Y, big kid 1Y–7Y, plus charts for socks and football boots.

Nike runs small in men’s shoes, against 23 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s under 1% of the time, about the same (within 2.5 mm) 42% and a shorter one 58%, typically by half a size. Go about half a size up from the size you wear in most brands, or size from your foot length on its chart.

Women’s sizes in men’s Nike

Nike’s charts print the women’s size beside each men’s size, 10.5 beside 9 for example, 1.5 sizes apart. But Nike’s women’s chart makes every women’s size for a foot 4 to 5 mm longer than the men’s size printed beside it: a women’s 10.5 is for a foot up to 26.7 cm, the men’s 9 up to 26.2 cm.

That is about half a size. If your foot fills your women’s size, a men’s pair converted by the printed column is made for a slightly shorter foot: choose the men’s size from your foot length on its men’s chart instead.

Is a youth (GS) size the same as men’s?

The numbers match, and so do UK and EU: 3.5Y is printed beside men’s 3.5, and 7Y beside men’s 7. The foot lengths don’t: Nike’s big-kid chart makes all 8 of these sizes for a foot 1 to 6 mm longer than the men’s chart does, largest at the small end (3.5Y up to 22.2 cm, men’s 3.5 up to 21.6 cm).

Below men’s 3.5 the men’s chart stops, and the big-kid chart goes on down to 1Y, which it prints beside a men’s 1 and a women’s 2.5.

Does Nike run big or small?

From Nike’s own foot lengths: first against the other brands’ charts, size for size (whether a US size is made for a longer or shorter foot than theirs), then against the standard size tables, foot by foot. Brands measure differently (Nike’s chart, for one, prints a box size in centimetres beside the foot length and says the two differ), so this is what each chart advises, not a fit test.

Men’s

Against the standard size tables, Nike’s chart gives the same US size for 12 of 13 foot lengths from 24.0 to 30.0 cm (for the other 1, half a size smaller).

For example, Nike’s men’s US 9 is for a foot up to 26.2 cm (the standard US 9: 26.25 cm). The other 23 brands’ charts make it for a foot from 26.0 to 27.7 cm: 2 for a shorter foot than Nike’s, 4 for about the same (within 1 mm) and 17 for a longer one.

Charts that size like Nike’s: adidas, HEYDUDE, KEEN, SOREL, HOKA, ANTA, Clarks and Reebok.

Women’s

Nike sits in the middle in women’s shoes, against 21 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s 21% of the time, about the same (within 2.5 mm) 44% and a shorter one 34%. Your usual US size is a good start; check your foot length on its chart.

Against the standard size tables, Nike’s chart gives a US size half a size to a size smaller for 12 of 12 foot lengths from 22.0 to 27.5 cm: its sizes allow a longer foot than the standard ones.

For example, Nike’s women’s US 8 is for a foot up to 24.5 cm (the standard US 8: 24.1 cm). The other 21 brands’ charts make it for a foot from 24.0 to 25.3 cm: 4 for a shorter foot than Nike’s, 8 for about the same (within 1 mm) and 9 for a longer one.

Charts that size like Nike’s: Salomon, adidas, HEYDUDE, SOREL, Veja, HOKA and ANTA. Charts that size like the standard tables: KEEN, Clarks, Crocs and Reebok.
