Baby Clothing Sizes

European baby clothing sizes are based on baby’s height in cm. While not widely used in Ireland, the European baby size chart is the most accurate as it is based on a child’s height regardless of age, after all not every 6 month old baby is the same height.

Below is a chart showing baby clothes size by age and by height from newborn to 2 years old.
