About
Our Baby Growth Percentile Calculator helps parents and healthcare providers track infant and child growth using standardized WHO and CDC growth charts for accurate development monitoring.
Why Choose
Based on official WHO and CDC growth standards, providing accurate percentile calculations for weight, height, head circumference, and BMI with comprehensive growth analysis.
Features
Multiple growth metrics tracking, percentile visualization, growth velocity analysis, weight-for-height ratios, and developmental milestone comparisons for complete assessment.
Benefits
Early detection of growth concerns, tracking healthy development patterns, informed discussions with pediatricians, and peace of mind for parents monitoring their child's growth.
Enter Baby Information
Input your baby's gender, age (years, months, days), and select the appropriate growth chart standard (WHO for 0-24 months, CDC for 2-20 years).
Add Measurements
Enter current weight, height/length, and optionally head circumference and birth weight for comprehensive growth analysis and tracking.

Frequently Asked Questions - Baby Growth Percentile Calculator
Growth percentiles compare your baby to other children of the same age and gender. The 50th percentile means average - half of children are larger, half are smaller. 75th percentile means your baby is larger than 75% of children the same age. Percentiles between 3rd-97th are typically considered normal.
Consult your pediatrician if your baby: drops more than 2 percentile lines, is below the 3rd percentile or above the 97th percentile, shows no weight gain for several weeks, or if you notice significant changes in eating, sleeping, or behavior. Consistent growth patterns are more important than specific percentile numbers.
WHO charts (0-24 months) are based on breastfed babies from diverse populations and show how children should grow under optimal conditions. CDC charts (2-20 years) reflect how American children typically grow and include formula-fed babies. WHO is recommended for infants and toddlers, CDC for older children.
For healthy babies: weekly during the first month, every 2 weeks until 6 months, then monthly until age 2, and every 3-6 months thereafter. Your pediatrician will track growth at regular check-ups. Daily weighing is unnecessary and can cause anxiety - focus on overall growth trends over time.
Minor fluctuations are normal, especially during growth spurts, illness, or developmental milestones. Babies often "channel" into their genetic growth pattern during the first 2 years. Consistent tracking over time is more meaningful than individual measurements. Significant or persistent changes should be discussed with your healthcare provider.
