Average Weight for a 12-Year-Old Girl at 4 ft 10 in: CDC Insights

According to CDC growth charts, a 12-year-old girl who is 4 ft 10 in (58 in / 147 cm) tall has a median (50th percentile) weight of approximately 91 lbs (41.3 kg).

Healthy Weight Range

The 5th–85th percentile BMI-for-age range for this height/age is roughly 78–112 lbs (35–51 kg). This wide range reflects normal variation in body composition and puberty timing.

Key Points

• Average ≠ Target: The 50th percentile is a statistical midpoint, not a goal.
• Puberty impact: Girls often gain 15–55 lbs during puberty; timing varies enormously.
• Assess trends, not snapshots: Track BMI percentile over time on the growth curve.
• Body composition matters: Muscle, bone density, and fat distribution affect health more than weight alone.

When to Consult a Professional

If weight crosses percentile lines rapidly, falls below 5th or above 85th percentile, or if there are concerns about eating behaviors, body image, or metabolic health—see a pediatrician or adolescent medicine specialist.
