What is the BMI for 160 lbs at 6'3"?
20.0 (Normal weight) — for someone who weighs 160 pounds and stands 6 feet 3 inches tall, the BMI is 20.0 (Normal weight). Body Mass Index is calculated by dividing weight in pounds by height in inches squared, then multiplying by 703.
BMI categories are: Underweight (below 18.5), Normal weight (18.5 to 24.9), Overweight (25.0 to 29.9), and Obese (30.0 and above). BMI does not account for muscle mass, bone density, age, or gender, so it should be used alongside other health indicators.
Below is the step-by-step calculation used to determine the result.

Frequently Asked Questions
Is BMI an accurate measure of health?
BMI is a screening tool, not a diagnostic one. It does not account for muscle mass, bone density, age, or body composition. Athletes may have a high BMI but low body fat.
What should I do if my BMI is outside the normal range?
Consult a healthcare provider. BMI is one of many indicators — they can assess your overall health using additional measurements and tests.
How often should I check my BMI?
Checking every few months is sufficient unless you are on an active weight management plan. Focus on trends over time, not single readings.
