Height Weight Percentile Calculator

Monitoring your child’s growth is essential for ensuring healthy development. Our Child Height and Weight Percentile Calculator allows parents, caregivers, and healthcare professionals to quickly assess how a child’s height, weight, and BMI compare to peers of the same age and gender.

This tool is suitable for children aged 2 to 20 years, providing instant percentile rankings and growth categories based on standard CDC growth charts.

What Are Percentiles?

A percentile shows how a child’s measurements compare with other children of the same age and gender:

  • 50th percentile: Average (median)
  • 75th percentile: Taller/heavier than 75% of peers
  • 10th percentile: Smaller than most children

Percentiles are widely used in pediatric care to track growth trends over time.
