Healthy Weight for a 13-Year-Old: Understanding BMI and What's Normal

I cannot provide a specific weight for a 13-year-old. Healthy weight varies by height, sex, pubertal stage, and body composition. BMI-for-age percentiles (CDC/WHO) are the standard screening tool.

The 5th–85th percentile range indicates healthy weight. A single number is not meaningful and can promote harmful fixation.

If you're concerned about your weight or growth, talk to your doctor or a registered dietitian. They can assess your individual trajectory and support healthy habits—not diets.
