1. What is Height Percentile?

Height percentile indicates how a child's height compares to others of the same age and gender. For example, a 75th percentile height means the child is taller than 75% of peers.

2. How Does the Calculator Work?

The calculator compares the input height and age to standardized growth charts:

Growth charts show:

• 5th percentile - 95% of children are taller
• 50th percentile - Average height
• 95th percentile - Only 5% of children are taller

3. Importance of Height Percentile

Details: Tracking height percentiles over time helps identify growth patterns and potential health issues. Consistent extreme percentiles or sudden changes may warrant medical evaluation.

4. Using the Calculator

Tips:

• Measure height without shoes
• Use exact age in years (decimal for months)
• For children under 2, use length measured lying down

5. Frequently Asked Questions (FAQ)

Q1: What growth charts are used?
A: CDC growth charts for United States children aged 0-20 years.

Q2: Is height percentile the same as BMI?
A: No, BMI considers both height and weight. Height percentile looks only at height relative to age.

Q3: When should I be concerned about percentiles?
A: Consult a pediatrician if:

• Below 5th or above 95th percentile consistently
• Sudden change in percentile trajectory
• Height and weight percentiles differ significantly

Q4: Do percentiles predict adult height?
A: They can indicate trends but aren't perfect predictors. Genetics and other factors play major roles.

Q5: How often should height be measured?
A: Every 3-6 months for children, annually for teens and adults.
