In the UAE, you will see shoe sizes written in European (EU) numbers in some shops and American (US) numbers in others, and online brands often use both. That makes a kids shoe size chart EU to US one of the most useful things a parent can bookmark. This page gathers the size pairs we use for BILLY Footwear, taken from the FARID HUB size guide, so you can convert quickly and order with more confidence.
A quick note before the tables: these pairs are BILLY Footwear's size mapping. Other brands may use slightly different conversions, so always check the chart of the brand you are buying.
How to read EU and US sizes
EU sizes are whole numbers (for example 30) or, for adults, sometimes a range (for example 37-38). US sizes are split by group: Toddler (the smallest sizes), Little Kid, Big Kid, then Women's and Men's. The same number can appear in more than one group, so "1 US Little Kid" and "1 US Women" are completely different sizes.
For the fit itself, start from the foot, not the number. Measure the longer foot, as explained in our guide to measuring your child's foot at home, then match the length to a size. Width matters too, and BILLY styles come in different widths depending on the model, so check each product page.
Kids and toddlers chart (EU 20-39)
| US size | EU size |
|---|---|
| 5 US Toddler | 20 |
| 6 US Toddler | 22 |
| 7 US Toddler | 23 |
| 8 US Toddler | 24 |
| 9 US Toddler | 25 |
| 10 US Toddler | 27 |
| 11 US Little Kid | 28 |
| 12 US Little Kid | 30 |
| 13 US Little Kid | 31 |
| 1 US Little Kid | 32 |
| 2 US Little Kid | 33 |
| 3 US Little Kid | 34 |
| 4 US Big Kid | 36 |
| 5 US Big Kid | 37 |
| 6 US Big Kid | 38 |
| 7 US Big Kid | 39 |
If you are searching for "what size is EU 30?", the answer in this chart is 12 US Little Kid. Notice that the chart does not list every EU number, such as 26, 29 or 35. That is how the BILLY mapping works. If your child's measurement lands near a missing number, we suggest asking us instead of guessing.
Princepard children's shoes are sized separately. The Princepard orthopedic shoe on our store lists EU 20-36, and its product page has its own sizing chart in the images. Do not mix it with the BILLY chart above.
Women's chart (US 6-12)
| US size | EU size |
|---|---|
| 6 US Women | 36-37 |
| 6.5 US Women | 37 |
| 7 US Women | 37-38 |
| 7.5 US Women | 38 |
| 8 US Women | 38-39 |
| 8.5 US Women | 39 |
| 9 US Women | 39-40 |
| 9.5 US Women | 40 |
| 10 US Women | 40-41 |
| 11 US Women | 41-42 |
| 12 US Women | 42-43 |
Where you see a range such as 37-38, the shoe sits across two European numbers. This is common on adult sizing, and it is one reason the US number is the easier one to use for BILLY adult styles.
Men's chart (US 7-15)
| US size | EU size |
|---|---|
| 7 US Men | 40 |
| 7.5 US Men | 40-41 |
| 8 US Men | 41 |
| 8.5 US Men | 41-42 |
| 9 US Men | 42 |
| 9.5 US Men | 42-43 |
| 10 US Men | 43 |
| 10.5 US Men | 43-44 |
| 11 US Men | 44 |
| 11.5 US Men | 44-45 |
| 12 US Men | 45 |
| 13 US Men | 46 |
| 14 US Men | 47 |
| 15 US Men | 48 |
Some women prefer men's styles and some men prefer women's, particularly with unisex-looking sneakers. If you are crossing between charts, check the product page, because styles are listed as men's or women's sizing and the available widths can differ.
Tips for using any size chart
- Use the longer foot. Most people have one foot slightly bigger than the other.
- Think about width and depth. Two people with the same length can need very different shoes. BILLY styles come in medium, wide and extra-wide options on many products, so check the product page.
- Allow for a brace, orthotic or thicker socks. If you or your child wear a brace, an orthotic, or removable insoles, sizing can change. Read our post on how to size adaptive footwear with confidence, and ask your orthotist or podiatrist if you are unsure.
- Re-check before each order. Feet change, especially in children, and styles can fit differently from each other.
