Use BMI to quickly estimate whether your weight is in a healthy range for your height.
BMI is a helpful screening tool, but it can overestimate risk for muscular athletes. Pair it with body fat or waist-based metrics for better context.
Most guidelines cite 18.5–24.9 as the general healthy range for adults, but individual factors still matter.
