Weight Percentile Calculator
Data collected in the WHO Multicentre Growth Reference Study was standardized to provide growth charts and weight percentile tables with the purpose of checking infant (from birth to 5 years of age) weight with respect to normal development.
The most rapid weight gain occurs during infancy with most babies doubling their birth weight between the fourth and sixth month and triple it by 12 months old.
Weight growth tends to slow down between 12 and 24 months with only about 2.26 kg (5 lbs) weight increase, a rate that remains relatively constant between 2 and 5 years old.

Weight Percentile Growth Charts
Weight percentile tables developed by WHO for boys and girls aged up to 5 years old help determine whether a child is developing harmoniously from a weight perspective. Based on the child’s age and measured body mass, a percentile is identified.
With respect to comparing growth at different ages, it is important that the child is placed under the normal growth percentile line and that they usually follow the same line during two different measurement at two different moments.
The most rapid weight gain occurs during infancy with most babies doubling their birth weight between the fourth and sixth month and triple it by 12 months old. Weight growth tends to slow down between 12 and 24 months with only about 2.26 kg (5 lbs) weight increase, a rate that remains relatively constant between 2 and 5 years old.
If the baby weighs in at a high percentile this is not usually a cause for concern, especially if both parents have larger body frames. But the weight of the baby will be monitored over subsequent checks to prevent overfeeding or other causes.
The weight growth charts are often used in conjunction with height growth charts to check for normal development so you can use the Height Percentile Calculator to check whether the baby’s height is developing harmoniously. An indicator of this is whether the percentiles are within a 10 to 20 percent range of each other.
