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.
Enter your child’s measurements once — we’ll size them in Zara Kids and at 100+ other brands, each from that brand’s own published chart. Height and weight are required; add chest, waist, hips and inseam to sharpen the fit.
Pick the size your child wears at Zara Kids to see which brands have the same label and measurements (twins) and which run shorter or longer (strangers) — based on each brand’s own chart.

Sizes shown use Zara Kids’ girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
Where the number just works. At 0-1 months, 1-3 months, 6-9 months, 9-12 months, 2-3 years, 3-4 years and more, 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 12-18 months, Hanna Andersson, Kyte Baby, Old Navy 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.

Zara Kids-specific things the size number alone won’t tell you — drawn from its own charts.
Zara sizes the European way: a centimeter-based chart labelled by age, printed here as age ranges like “4-5 years”. Don’t carry over another brand’s US number — size to your child’s measurements against Zara’s own guide.
Sizing up is the near-universal advice. The slim, fashion cut reads narrower and shorter than the US brands you may be used to, so a size feels smaller than the same age elsewhere.
Fit varies by piece — parents find the tops truer to size while the bottoms run smallest, so check trousers and shorts especially.
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.
Enter your child’s measurements once. We’ll show their Zara Kids size and their size at 100+ other brands, each from that brand’s own chart.
Find my child’s size →Shop Zara Kids ↗Zara uses European, height-based sizing in centimeters, labelled by age (for example 4–5Y ≈ 104–110 cm). 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.
From the bigger sizes up, Zara Kids publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use Zara Kids’ girls’/unisex chart.
