What size clothing does a 3-year-old boy wear?
Most childrens clothing is sold by age and is usually labelled, for example; “Will fit boys aged 2 to 4” or “Ages 9 to 10,” etc. Some 3 year old boys will be bigger and heavier than others of that age and may need larger sizes of clothes. According to 121uniforms website average height for a 3 to 4 year old boy is 104Cm (41 inches), average chest measurement is 54cm (21.25 inches) and average waist size is 52cm (20.5 inches). I’m not entirely sure why you have asked this question in the male puberty category though.
