Change your height or weight to see how your BMI changes.
Understanding Your BMI
A BMI in the 18.5-24.9 range is considered healthy by CDC and WHO standards. This range is associated with the lowest risk of cardiovascular disease and type 2 diabetes.
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
Gaining approximately 16.1 lbs would bring your BMI to 25, the start of the next category.
⬆️ Gaining approximately 16.1 lbs would put you in the Overweight BMI range.
⬇️ Losing approximately 24.2 lbs would bring you to the Underweight 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 15-year-old girl at 5ft 6in and 139lbs, a BMI of 22.4 would be evaluated using pediatric growth percentiles rather than the adult normal category.
