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 women of average height, BMI is a reliable screening tool. Pair it with waist circumference for a more complete health picture.
Weight & Threshold
Losing approximately 14.7 lbs would bring your BMI to 40, the boundary of the healthy weight range.
⬇️ Losing approximately 78.5 lbs would bring you to the Overweight BMI threshold.
Waist & Health
The CDC recommends that non-pregnant women keep waist circumference below 35 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 13-year-old girl at 5ft 7in and 270lbs, a BMI of 42.3 would be evaluated using pediatric growth percentiles rather than the adult obese category.
