Healthy Weight for a 15-Year-Old Boy at 5'2": CDC Percentiles & Context

According to CDC growth charts, a 15-year-old boy who is 5'2" (62 inches) has a 50th-percentile (median) weight of about 106 lb (48 kg). The broad healthy range (5th–85th percentile) spans approximately 80–130 lb (36–59 kg).

Why This Range Is So Wide

• Puberty timing: At 15, boys can be in early, mid, or late puberty. Early bloomers may be taller and heavier; late bloomers lighter and shorter.
• Body composition: Muscle weighs more than fat. An athletic boy may weigh more but have lower body fat.
• Genetics: Parental height and build strongly influence trajectory.

Better Indicators Than Weight Alone

• BMI-for-age percentile: Accounts for height; 5th–85th percentile is healthy weight.
• Growth velocity: Consistent tracking along a curve matters more than a single point.
• Waist circumference & fitness: Central adiposity and cardiorespiratory fitness are stronger health predictors.

When to Seek Guidance

Consult a pediatrician or registered dietitian if:

• Weight crosses percentile lines rapidly (up or down).
• BMI is <5th or >95th percentile.
• There are concerns about disordered eating, excessive exercise, or delayed puberty (no testicular enlargement by age 14).
