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
Losing approximately 19.7 lbs would bring your BMI to 40, the boundary of the healthy weight range.
⬇️ Losing approximately 95.5 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 adults 65 and older, BMI targets shift. Clinical guidelines (ESPEN, NIH) often recommend a slightly higher BMI range (around 23–26) for seniors to protect against bone loss and muscle decline. At 65 years old, a woman at 6ft 1in and 323lbs has a BMI of 42.6.
Your BMI of 42.6 falls into the Obese category. At age 65, doctors often focus more on mobility, waist size, and functional ability than BMI alone.
