What Is BMI?
BMI (Body Mass Index) is a measurement that compares weight to height.
BMI=Height(m)2Weight(kg)
In this tool, BMI is calculated using imperial units and converted internally.
What Is a Percentile?
A percentile shows how a child compares to others of the same age and gender.
For example:
- 50th percentile = average growth
- 75th percentile = above average
- 25th percentile = below average
Percentiles help understand relative growth patterns.
Understanding Growth Categories
Height Percentile
- 75%+ → Taller than most children
- 50% → Average height
- 25% → Shorter than average
Weight Percentile
- 75%+ → Heavier than most children
- 50% → Average weight
- 25% → Lower weight range
BMI Percentile
- 75%+ → Higher body weight ratio
- 50% → Healthy range
- 25% → Lower BMI range
Why Growth Tracking Matters
Tracking child growth is essential for early health awareness.
Benefits Include:
- Detecting growth delays
- Identifying obesity risks
- Monitoring nutrition quality
- Supporting healthy development
