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 over 5ft 11in, BMI may slightly underestimate body fat due to higher bone density. Muscle mass is also a factor—consider body fat percentage as a complementary measure.
Weight & Threshold
Gaining approximately 50.9 lbs would bring your BMI to 40, the start of the next category.
⬇️ Losing approximately 31.2 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
At ages 18-19, BMI interpretation transitions. This age range sits between pediatric percentiles and adult fixed cutoffs. A 19-year-old woman at 6ft 4in and 278lbs has a BMI of 33.8, which falls into the Obese category under adult CDC/WHO standards.
