Growth Curve Formula

The calculator uses standard pediatric growth charts based on World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) guidelines. Measurements are compared to percentile ranges for each age group.

Understanding Growth Milestones

Babies grow at different rates, but there are general milestones to watch for:

Age	Weight	Height	Head Circumference
Newborn (0-1 month)	2.5-4.5 kg (5.5-10 lbs)	47-53 cm (18.5-20.9 in)	32-36 cm (12.6-14.2 in)
1 month	3.2-5.2 kg (7-11.5 lbs)	51-56 cm (20.1-22 in)	34-38 cm (13.4-15 in)
3 months	5.5-7.5 kg (12.1-16.5 lbs)	58-63 cm (22.8-24.8 in)	38-42 cm (15-16.5 in)
6 months	7-9 kg (15.5-20 lbs)	65-70 cm (25.6-27.6 in)	42-46 cm (16.5-18.1 in)
9 months	8.5-11 kg (18.7-24.3 lbs)	70-75 cm (27.6-29.5 in)	44-48 cm (17.3-18.9 in)

These are approximate ranges. Always consult with your pediatrician for personalized advice.

Important Note

Every baby develops at their own pace. Some babies may grow faster or slower than the average. If you have concerns about your baby's growth, consult with your pediatrician immediately.

Methods for Tracking Growth

Pediatrician visits: Regular check-ups provide the most accurate measurements
Baby growth charts: Use this calculator to track progress over time
Baby journals: Record measurements and milestones
Baby scales: Use a baby scale at home for regular weigh-ins
Height measurements: Use a wall-mounted stadiometer or portable measuring board

Consistent tracking helps identify any potential growth issues early.
