Brand sizing can vary by garment type. When in doubt, size up.

How to measure your child correctly

The best way to get the right fit is to measure your child's height and foot length instead of relying only on the age label. Stand them barefoot against a wall for height, and measure foot length from heel to longest toe — ideally at the end of the day.

Always compare your measurements with the brand's own size chart before ordering. If your child falls between two sizes, fitted pieces need a closer size, while coats and shoes usually work better with a little extra room.

Quick tips

  • Measure height without shoes.
  • Measure foot length from heel to longest toe.
  • Compare measurements with the brand's official chart.
  • If between sizes, think about fit, fabric, and season.
  • For shoes, leave a little extra room for comfort and growth.

Why sizes differ by brand and country

Children's clothing sizes are not universal. A size marked 2–3Y in one brand may fit smaller, wider, longer, or shorter in another, even when both brands are selling for the same age group.

This happens for two reasons. First, countries use different sizing systems — such as EU, US, UK, and FR/IT. Second, each brand builds its own fit based on design choices, target market, and product type. That's why Zara, H&M, Next, Boden, and other brands often feel different even when the label looks similar.

Age is a useful starting point, but it should not be your only reference. In most cases, height gives a more reliable clothing match, and foot length gives a better shoe estimate than age alone.

A practical rule: start with age, confirm with height, and double-check the brand chart before buying. That extra step can save time, returns, and guesswork.

Frequently Asked Questions

What does 13Y 152–158 cm mean?

13Y means the size is designed for a 13-year-old. The numbers 152–158 cm indicate the height range the garment fits — so if your child is between 152 and 158 cm tall, this is their size.

What does 11Y 140–146 cm mean?

Size 11Y fits children aged around 11, with a height of 140 to 146 cm. European brands like Zara and H&M use height in centimeters as their primary size guide.

What is youth size 1 in European sizing?

US Youth size 1 in shoes corresponds to approximately EU size 32–33. Children's shoe sizes vary by brand — always check the specific brand's size chart for the most accurate fit.

What is children's size 2 in EU?

A US children's size 2 (toddler) is approximately EU size 33. For clothing, US size 2T fits children around 2 years old, which is roughly EU size 92 (for a child ~92 cm tall).

What is EU size 92 in US sizes?

EU size 92 corresponds to approximately US size 18–24 months or 2T, designed for children around 86–92 cm tall and weighing 11–14 kg.

What does 2T mean in kids clothing?

How do I measure my child's height at home?

Stand your child barefoot against a flat wall. Place a book flat on top of their head touching the wall, then mark the wall. Measure from the floor to the mark in centimetres.

Should I size up when buying kids clothing?

Yes, in most cases. Children grow quickly, and many parents prefer buying one size up so clothes last longer. For fitted items like swimwear or socks, stick to the exact size.

Are Zara and H&M kids sizes the same?

Not exactly. Zara Kids tends to run slightly larger than H&M Kids at the same labelled age. For example, a Zara 2–3 years is often closer to H&M 3–4 years in actual measurements.

What is the difference between EU and UK kids sizes?

EU kids sizes are based on height in centimetres (e.g. 92, 98, 104). UK sizes use age ranges (e.g. 2–3 years). They are approximate equivalents, but the same height measurement is the most accurate way to compare.

How does height compare to age for kids clothing?

Height is a more accurate guide than age, since children grow at very different rates. A child of 3 years might fit anywhere from EU 92 to EU 110 depending on their actual measurements.
