A boys' pants size chart typically shows sizes, approximate ages for each size, and height and waist measurements for each size. Charts may include inseam measurements, hip measurements and an approximate weight for each size. Information included varies based on the manufacturer.
Some manufacturers offer slim or husky boys' pants, for boys that need clothing of different proportions. The difference is usually in waist size, while other measurements remain the same. Slim pants are smaller in the waist, while husky pants are wider.
A height measurement is obtained by measuring from the floor to the top of the head when the boy stands straight. A waist measurement is obtained by measuring around the waistline at the narrowest point. Clothes are not worn during a waist measurement. An inseam measurement is the distance from the crotch intersection to the foot, and this measurement can be taken wearing pants. A hip measurement is taken for the fullest part of the hips.
Other types of children's pants sizes are girls, coed and toddler. Girls' pants are designed specifically for girls, while coed pants can be worn by girls or boys. Toddler pants are for children between the ages of two and eight. Baby clothes are available for children younger than two.
