Understanding Your BMI of 20.0

A BMI of 20.0 at 5'5" and 120 pounds places you in the “Normal weight”category. BMI (Body Mass Index) is a screening tool that estimates body fat based on height and weight. It's calculated by dividing weight in pounds by height in inches squared, then multiplying by 703.

BMI = (120 ÷ 65²) × 703 = 20.0

For your height of 5'5", a healthy weight (BMI 18.5 to 24.9) falls between 111 and 150 pounds.

Keep in mind that BMI is a screening tool, not a diagnostic. It does not account for muscle mass, bone density, age, sex, or body composition. Athletes and muscular individuals often have a high BMI despite being healthy. Always consult a healthcare provider for a complete health assessment.
