Crocs size chart at a glance#

Frequently asked questions#
Do Crocs run true to size?#
Crocs tend to run roomy rather than true to size, so most people size down or choose the smaller whole size when between sizes. They come in whole sizes only, so measure your foot heel to toe and match the length: a US men's 10 fits an 11 in (28 cm) foot, a women's 8 a 9.4 in (24 cm) foot.
Should I size up or down in Crocs?#
It depends on the style's fit. Crocs styles come in relaxed, roomy and standard fits: relaxed and roomy styles leave extra room, so the smaller whole size usually still fits securely, while in a standard-fit style the larger size gives your toes room. Check the fit named on the product page before choosing.
How do I measure my feet for Crocs?#
Place a sheet of paper on the floor, step on it barefoot, and mark the longest part of your foot from heel to toe. Measure that length in inches or centimeters and read across the chart: a 24 cm foot is a men's 6, a women's 8 or a kids' J6. Crocs run roomy, so if your length lands between two whole sizes, take the smaller one.
Are Crocs available in half sizes?#
No, Crocs come in whole sizes only. If you wear a half size, pick a whole size using the style's fit as your guide (see the size up or down question above).
What size is J6 in men's or women's Crocs?#
J6, the largest kids' size, fits a 9.5 in (24.2 cm) foot and converts to EU 38-39, the same EU range as a men's 6 or a women's 8 on the adult charts, so J6 wearers can usually move straight into those adult sizes.
How should Crocs fit on my feet?#
Crocs should fit securely with enough room for your toes to wiggle and a snug fit around the heel. The clogs should not be so loose that they slip off your foot but not so tight that they cause discomfort.
Sizing tips#
- Measure both feet: feet are often slightly different sizes; fit the larger one.
- Check the style: Crocs fits vary by style (relaxed, roomy or standard), so check which fit the style uses before picking your size.
