Weight & Height

Are you curious about your child’s weight and height? You’re not alone. As parents we tend to worry about every little thing about our kids, including how tall they are or what their weight is compared to other children their age. The average baby weighs about 7.3 pounds(3.3kg) and 19.4 inches(49.2cm) at birth.

You can find the growth chart below, representing the 25th percentile to the 75th percentile for weight and height – meaning that half of kids fall within these ranges. A quarter of kids fall above these numbers and a quarter of kids below them.

Please keep in mind that height and weight ratio charts are not truly accurate measures especially for young children and teenagers. These figures are a rough average and should be used in conjunction with a BMI calculator for kids
