Frequently Asked Questions
What is a baby weight percentile?
A baby weight percentile shows how your baby's weight compares to other babies of the same age and gender. For example, if your baby is in the 75th percentile, they weigh more than 75% of babies their age. Percentiles help track healthy growth patterns over time.
How do I calculate my baby's weight percentile?
Enter your baby's weight (in pounds and ounces), age in months, and gender in the calculator above. The calculator uses WHO growth standards (for babies 0-24 months) and CDC growth charts (for older babies) to determine your baby's weight percentile compared to other babies of the same age and gender.
What is a normal weight percentile for babies?
A normal weight percentile range is typically between the 5th and 95th percentiles. Percentiles between 25th and 75th are considered average. However, what's most important is consistent growth along your baby's own growth curve. Always consult with your pediatrician about your baby's growth.
Why is tracking weight percentiles important?
Tracking weight percentiles helps monitor your baby's growth and development. Consistent growth along a percentile curve is usually a sign of healthy development. Significant changes in percentile may indicate the need to discuss with your pediatrician.
Can I track growth milestones privately with family?
Yes! With Clann, you can save growth milestones privately with your family. Share weight check photos, add voice notes from family members about your baby's growth, and let Clann automatically create monthly memory books. Your family can see your baby grow and track milestones together.
How often should I check my baby's weight percentile?
Most pediatricians check weight at regular well-baby visits (typically at 2 weeks, 1 month, 2 months, 4 months, 6 months, 9 months, 12 months, and then annually). You can use this calculator between visits to track growth, but always discuss concerns with your pediatrician.
