The standard answer to what size is 110 in children’s clothes is that it corresponds to a child who is approximately 110 centimeters tall. This usually converts to a US size 5T or 5 and a UK size 4–5 years. When shopping globally—especially on brands like Shein—always check the garment-specific 110 size conversion chart because metric-based clothing often runs smaller than US sizing.

If you’ve ever browsed international kids’ clothing and spotted a tag that simply says “110,” you’re not alone in wondering what that actually means. It’s one of the most common points of confusion in global children’s fashion—and the good news is, it’s not random at all. In fact, the answer to what size is 110 in children’s clothes is surprisingly straightforward.

Size 110 is part of the metric sizing system and corresponds directly to the child’s height. Below, you’ll find the definitive explanation, the must-have 110 size conversion chart, and helpful advice for US/UK shoppers navigating brands like Shein, H&M, Zara, and other international retailers.

Defining the Metric Standard: The Power of Height

Metric sizing is based on one core idea:
The number on the label equals the child’s height in centimeters.

So, size 110 means the clothing is designed for a child who is around 110 cm tall—usually between 4 and 5 years old, depending on body shape and growth patterns.

Why Measuring a Child’s Height Matters

Age can be misleading. Two children who are both four years old can differ by 10–12 cm, making age-based sizes unreliable.
That’s why measuring a child’s height with a tape measure is the most accurate method when shopping internationally.
