About Pediatric Growth Assessment
Growth Standards
This calculator uses WHO growth standards for children under 2 years and CDC growth references for children 2-18 years. Percentiles indicate how a child compares to a reference population of the same age and sex.
- • 3rd-97th percentile: Normal range
- • <3rd or >97th: May warrant evaluation
- • Crossing percentiles: Track trends over time
Clinical Considerations
- • Growth velocity is as important as absolute percentiles
- • Consider parental height when evaluating short stature
- • Head circumference most important in first 3 years
- • BMI interpretation differs for children vs. adults
- • Premature infants may need adjusted age calculations
- • Growth charts are screening tools, not diagnostic
Disclaimer: This calculator provides estimates based on population growth data and should be used as a screening tool only. Always correlate with clinical findings and consider individual patient factors. Consult appropriate specialists for growth concerns.
