Growth Percentile Calculation:
| From: | To: |
Baby growth percentiles compare a child's measurements (height, weight, head circumference) to a reference population of the same age and gender. They help track growth patterns and identify potential health concerns.
The calculator uses WHO growth standards:
Where:
Explanation: The calculation compares your baby's measurements to standardized growth charts developed by WHO based on healthy breastfed infants from diverse backgrounds.
Details: Regular growth monitoring helps identify nutritional issues, genetic conditions, and overall health status. Consistent tracking of growth patterns is more important than individual measurements.
Tips: Enter baby's age in months (0-60), measurement in cm or kg, select measurement type and gender. Use accurate measurements taken during well-baby checkups.
Q1: What do different percentiles mean?
A: 50th percentile means average - half of children are smaller, half are larger. 5th-95th percentile is generally considered normal range.
Q2: Should I worry if my baby is in a low percentile?
A: Not necessarily. What matters most is consistent growth along a percentile curve. Sudden drops or rises may warrant medical attention.
Q3: How often should I measure my baby?
A: Monthly for first 6 months, then every 2-3 months until age 2, and every 6 months thereafter during routine checkups.
Q4: Are WHO charts different from CDC charts?
A: Yes, WHO charts are based on healthy breastfed infants as the biological norm, while CDC charts include both breastfed and formula-fed infants.
Q5: When should I consult a doctor?
A: If growth crosses two major percentile lines, if below 5th or above 95th percentile consistently, or if you have any concerns about feeding or development.
