Adjust Your Numbers
Change your height or weight to see how your BMI changes.
Understanding Your BMI
A BMI below 18.5 may indicate nutritional insufficiency. According to the CDC, this range is associated with increased risk of bone density loss and immune function decline. Consulting a healthcare provider is recommended for a thorough nutritional assessment.
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 35.1 lbs would bring your BMI to 18.5, the start of the next category.
⬆️ Gaining approximately 35.1 lbs would put you in the Normal BMI range.
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 11-year-old girl at 7ft 0in and 151lbs, a BMI of 15.0 would be evaluated using pediatric growth percentiles rather than the adult underweight category.
