Crocs sizes can look confusing at first. Labels show letters like M and W, kids’ sizes use C and J, and many styles come only in whole sizes. Once you understand the system, though, choosing the right pair becomes simple. This guide explains how Crocs sizing works for men, women and kids.

How Adult Crocs Sizes Work
Many Crocs are unisex. Their labels show both a men’s size and a women’s size, such as M7/W9. The “M” number is the men’s size, and the “W” number is the women’s size.
For unisex Crocs, the women’s size is usually two sizes higher than the men’s size. So a men’s 7 is roughly a women’s 9.
Some styles, such as many platforms, are sold in women’s sizes only. Always check the label and the product details.
Whole Sizes Only
Many Crocs styles come in whole sizes only, without half sizes. If you are between sizes, Crocs generally suggests choosing the next size up. Our guide on whether Crocs run big or small explains how to decide.
How Kids’ Crocs Sizes Work
Crocs uses two groups of sizes for children:
– C sizes for toddlers and younger children.
– J sizes for older children.
Here is a simplified guide based on Crocs’ children’s size chart, showing foot length in centimetres:
| Crocs size | Foot length (cm) | Crocs size | Foot length (cm) |
|---|---|---|---|
| — | — | — | — |
| C4 | 12 | C11 | 18 |
| C5 | 13 | C12 | 18.5 |
| C6 | 14 | C13 | 19 |
| C7 | 15 | J1 | 19.5 |
| C8 | 15.5 | J2 | 20 |
| C9 | 16.5 | J3 | 21 |
| C10 | 17.5 | J4 to J6 | 22 to 24 |
Size charts can vary slightly by region and style, so always check the official chart for the pair you are buying.
How to Use the Size Chart
Start by measuring your foot length. Our guide on how to measure your feet for Crocs shows you how. Then compare your measurement with the official chart for the style you want, and read any fit notes on the product page.
Imagine ordering Crocs for the whole family. You measure everyone’s feet on a Sunday afternoon, write down the results and check each against the chart. It takes a little time, but it saves the hassle of returns later.
Styles That Fit Differently
Lined Crocs often feel snugger, so many people size up. Platforms can feel different from flat clogs. Sporty clogs with adjustable straps can be tightened. Our guide on how Crocs should fit explains what a good fit feels like.
Final Thoughts
The Crocs size chart becomes simple once you know the basics: unisex labels show men’s and women’s sizes, the women’s number is usually two higher, kids use C and J sizes, and many styles come in whole sizes only.
Do you find Crocs sizing easy, or has it ever caught you out?
