Pediatric growth calculators for WHO and CDC references
Six independent calculators for pediatric growth assessment using WHO and CDC references, including BMI, growth change, corrected age, and family-height
About Child Growth Lab
Child Growth Lab provides six standalone pediatric growth calculators that turn documented growth references into transparent tools for adults. The calculators cover WHO baby growth standards, CDC child growth references, kids BMI screening, growth velocity over time, corrected-age timing for preterm births, and family-height context. Each calculator works independently in the browser without requiring an account or saving child health records. The site emphasizes transparent inputs, derived values, and sources, helping users understand results rather than receiving unexplained numbers.
