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 37.3 lbs would bring your BMI to 25, the start of the next category.
⬆️ Gaining approximately 37.3 lbs would put you in the Overweight BMI range.
⬇️ Losing approximately 1.8 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 72 years old, a woman at 5ft 5in and 113lbs has a BMI of 18.8.
Your BMI of 18.8 is within the standard range but sits near the lower end. Maintaining muscle mass through protein intake and light resistance training is particularly important at this age.
