About Height Percentile Calculator
Height percentile calculation is temporarily unavailable while the growth reference and measurement method are verified.
How to check a child's height centile
Use the age- and sex-appropriate UK-WHO growth chart and the correct measurement method for the child's age. RCPCH provides the UK-WHO growth charts and guidance for health professionals.
If you are concerned about a child's growth, speak with a health visitor, school nurse or GP rather than relying on an unverified online estimate.
