The convenient way is to let the child try it on directly or measure it accurately, but if the child is not present or can't measure it, as long as the height of the child is known, the children's clothes that fit can still be selected through calculation. Generally speaking, the head of a child accounts for 20% of the total height, and the height accounts for 80% of the total height. When choosing clothes for children, height is usually the standard.
The length of children's shorts is about 30% of their height; The length of children's shirts is about 50% of their height; The length of children's trousers is about 75% of their height; Children's coats are about 49% of their height; The length of the children's suit is about 53% of the height; Children's long coats are about 70% of their height; A girl's skirt is about 78% of her height.
For example, a girl with a height of 100 cm is 80% of the height of 100 cm, about 80 cm. If you buy a skirt, the length of the skirt is 70% of 80 cm, which is 56 cm. If you buy a shirt, the length of the shirt is 50% of 80 cm, which is 40 cm. If you go out to choose children's clothes for your children at home, you may wish to choose a dress that will satisfy your children.
