How do you choose a size of jeans for boys?

To measure a boy for size 4 and up jeans, use a flexible tape measure. Get the boy's waist size, hip size, and total height in inches. It also helps to know the boy's weight. For sizes 4 to 7, jeans are sized based on the boy's height and weight. For sizes 8 and up, the pants are sized based on height, waist, and hip measurements. Size 4 corresponds to a height of 42 to 44 inches and a weight of 37 to 41 pounds. For each 2-inch increase in height and 4-pound increase in weight, choose the next size up in jeans. Boys with a waist size of 23.5 inches, hips of 27.5 inches, and height of 50 to 53 inches fit into a size 8. For each 1-inch increase in waist or hips and 4-inch increase in height, go up one size of jeans. If a child is between sizes, choose the bigger pair.
