Adjust Your Numbers
Change your height or weight to see how your BMI changes.
Understanding Your BMI
A BMI of 30 or above indicates obesity. The CDC reports that this range is associated with a 50-60% higher risk of cardiovascular disease and type 2 diabetes. Comprehensive lifestyle intervention and medical guidance are strongly recommended.
What This Means for Your Height
For men over 6ft, BMI may overestimate body fat due to higher muscle mass. Consider waist circumference and body fat percentage for a more accurate assessment.
Weight & Threshold
Gaining approximately 48.5 lbs would bring your BMI to 40, the start of the next category.
⬇️ Losing approximately 33.7 lbs would bring you to the Overweight BMI threshold.
Waist & Health
The CDC recommends that men keep waist circumference below 40 inches. A waist-to-height ratio below 0.5 is also associated with lower health risks.
Age Context
For children and teenagers (under 18), BMI is interpreted differently. Unlike adults, BMI for youth is age- and sex-specific, using percentiles from CDC growth charts. For a 10-year-old boy at 6ft 4in and 280lbs, a BMI of 34.1 would be evaluated using pediatric growth percentiles rather than the adult obese category.
