Adjust Your Numbers
Change your height or weight to see how your BMI changes.
Understanding Your BMI
A BMI in the 25-29.9 range indicates excess weight relative to height. According to CDC data, this range is associated with a 20-30% higher risk of developing type 2 diabetes and hypertension.
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 2.6 lbs would bring your BMI to 30, the start of the next category.
⬆️ Gaining approximately 2.6 lbs would put you in the Obese BMI range.
⬇️ Losing approximately 40.7 lbs would bring you to the Normal 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 45-64, metabolic health becomes increasingly important. At 50 years old, a woman at 6ft 6in and 257lbs has a BMI of 29.7, which falls into the Overweight category.
At age 50, even modest weight loss can improve metabolic markers. Consider combining BMI with waist circumference for a more complete assessment.
