Healthy Weight for 18-Year-Old Girls: Factors & Guidelines

Healthy weight for an 18-year-old girl varies by height, build, and activity level. A general reference range is 100–140 lbs, but this is not prescriptive. Body composition (muscle vs. fat) matters more than scale weight.

If concerned, consult a healthcare provider for personalized assessment using BMI-for-age, body fat percentage, and overall health markers.
