Here’s how Zara Kids fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s Zara Kids size on the left. Twins wear the same number the same way — your size carries straight over. Strangers use the same number but cut it shorter or longer, so don’t trust the label alone.

|---|---|---|
| 2-336–38.6" | None — a universal size | |

Where the number just works. At 2-3, 4-5, Zara Kids lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 8-9, JoJo Maman Bébé, Rylee + Cru, Marks & Spencer cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Zara Kids number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Which trimmer, roomier, or adaptive cuts Zara Kids publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Zara Kids’ own published chart; the notes here come from public parent discussion.
Zara Kids runs small — sizing up is the near-universal advice. It uses European, height-and-centimeter sizing (labelled by age, like 4–5Y) with a slim, fashion cut, so a size reads narrower and shorter than the US brands you may be used to; parents specifically warn not to carry over another brand’s number. Fit can vary by piece — some find tops truer while the bottoms run smallest.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.

Our comparison converts it to US sizes from real height, and you can switch this page’s figures between inches and centimeters with the toggle above the table.
Yes — unlike the clothing, Zara’s kids’ shoes are generally reported to fit true to size, so you can buy your child’s usual shoe size with more confidence than the apparel.
No — parents report it holds its size and shape through washing rather than shrinking. The trade-off some note is pilling on certain fabrics over time, not a change in fit.

Height is the primary driver, with chest and waist as checks. Because it runs small and slim, size to your child’s actual height and round up when they’re between sizes or broad through the middle.
