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 under 5ft 2in, waist-to-height ratio is particularly important. Research suggests that even at a normal BMI, a waist-to-height ratio above 0.5 may indicate increased health risks.
Weight & Threshold
Gaining approximately 1.7 lbs would bring your BMI to 25, the start of the next category.
⬆️ Gaining approximately 1.7 lbs would put you in the Overweight BMI range.
⬇️ Losing approximately 25.3 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 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 80 years old, a woman at 4ft 6in and 102lbs has a BMI of 24.6.
Your BMI of 24.6 falls within a reasonable range. Focus on staying active and eating protein-rich foods to preserve muscle.
