EU children’s clothing is sized by height in centimeters, not age; the US uses age-based sizes like 2T, 3T, 4. An EU 104 (cm height) is a US 4T, sometimes labelled just "4."
The EU number in kids' clothing is the child's height in centimeters that the garment is cut for — EU 92 fits a child about 92 cm tall, EU 116 fits about 116 cm. The US instead labels by approximate age: 2T, 3T, 4T (or plain "4"), up through numbered youth sizes like 10, 12, 14.
Because kids grow at very different rates, height is a far more reliable guide than age — a tall 3-year-old and an average 4-year-old might both need an EU 104 / US 4T, even though the US label is nominally tied to age. If you know your child's height in cm, use that over their age when picking a size.

Clothing sizes are brand-assigned labels, not fixed measurements — use this as a starting point, not a guarantee.
EU 104 (for a child about 104 cm tall) is a US 4T, sometimes labelled simply "4" by US brands.
Height — the EU number is the centimeter height the garment is cut for, unlike the US system which labels by approximate age.
Height, if you know it — kids of the same age can vary a lot in size, and the EU system’s height basis makes it the more reliable starting point.
