Crocs size chart

Crocs’ own size charts: women’s clogs 4–19, unisex clogs M2/W4–M17/W19, kids clogs C1–J6.

Crocs runs large in men’s shoes, against 23 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s 52% of the time, about the same (within 2.5 mm) 35% and a shorter one 13%, typically by half a size. Go about half a size down from the size you wear in most brands, or size from your foot length on its chart.

Crocs’ charts at a glance

Chart	Sizes	Foot lengths
Women’s clogs	4–19	20.0–35.0 cm

Does Crocs run big or small?

From Crocs’ 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, Crocs’ chart gives a US size half a size to 1½ sizes smaller for 12 of 13 foot lengths from 24.0 to 30.0 cm: its sizes allow a longer foot than the standard ones.

For example, Crocs’ men’s US 9 is for a foot up to 27.0 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: 11 for a shorter foot than Crocs’, 10 for about the same (within 1 mm) and 2 for a longer one.

Charts that size like Crocs’: Saucony, Timberland, Vans, UGG, Dr. Martens, Fila, New Balance and Under Armour. Charts that size like the standard tables: Nike, adidas, HEYDUDE, KEEN, SOREL, HOKA, ANTA, Clarks and Reebok.

Women’s

Crocs runs small in women’s shoes, against 21 other brands’ charts: size for size, its chart is made for a longer foot than another brand’s 3% of the time, about the same (within 2.5 mm) 14% and a shorter one 83%, typically by a size. Go about a size up from the size you wear in most brands, or size from your foot length on its chart.

Against the standard size tables, Crocs’ chart matches on average (within 1 mm), stepping between them: for foot lengths from 22.0 to 27.5 cm it gives the same US size for 5, half a size larger for 4 and half a size smaller for 3.

For example, Crocs’ women’s US 8 is for a foot up to 24.0 cm (the standard US 8: 24.1 cm). The other 21 brands’ charts make it for a foot from 24.1 to 25.3 cm: 0 for a shorter foot than Crocs’, 2 for about the same (within 1 mm) and 19 for a longer one.

Charts that size like Crocs’: KEEN, Clarks and Reebok.
