The teenage years are a period of rapid growth and development. During adolescence, boys experience significant changes in height, weight, muscle mass, and overall body composition.
Weight is one indicator of growth and development. Tracking weight alongside height can help assess overall health and nutritional status throughout adolescence. While growth patterns vary from one individual to another, monitoring weight according to age can help parents and caregivers understand whether a teen is developing healthily. Proper nutrition, regular physical activity, and adequate sleep play important roles in supporting healthy growth during these years. This guide shows weight charts of teen boys and factors that affect their weight.

The teenage years are a crucial stage of growth and development. Balanzing offers nutrient-rich foods that help to improve the weight of teen boys. While weight can vary significantly among individuals, balanced nutrition, regular exercise, adequate sleep, and healthy lifestyle habits can help support healthy growth.
Check his BMI-for-age percentile — above the 85th percentile suggests overweight risk. Combine this with activity levels, diet quality, and a pediatrician's assessment for an accurate picture.
There's no fixed weight number — obesity is determined by BMI-for-age percentile. A teen boy at or above the 95th percentile for his age and height is generally classified as obese.
Rapid weight gain during puberty is often normal due to growth spurts. However, if it's sudden, unexplained, or paired with fatigue or mood changes, consult a pediatrician to rule out other causes.
Yes. Muscle is denser and heavier than fat, so athletic teens may weigh more despite looking lean. This is why BMI alone can be misleading without considering body composition.
For a 5'10" (70 in) teenage boy, a healthy weight typically falls between 135–165 lbs, depending on age, muscle mass, and body frame. A doctor can confirm using BMI-for-age percentiles.
Yes. Once puberty ends (typically by 18–19), growth stabilizes and weight becomes more closely tied to lifestyle, diet, and activity rather than hormonal growth spurts, making adult weight guidelines more applicable.

My son just turned 14 and has always been on the shorter side, so I was constantly comparing him to his classmates and worrying if something was wrong. This chart from Balanzing helped me understand that the percentile range matters more than a single number, and that boys hit their growth spurts at different times. Bookmarking this to check back in every few months. Thank you for breaking it down so clearly!
