BMI Calculator for Women

Health

Calculate your Body Mass Index and see which category it falls into. Enter your weight and height, and this calculator returns your BMI, its category, and the healthy weight range for your height.

Formula

BMI = weight (kg) ÷ height (m)² Healthy weight = 18.5–24.9 × height²
  • BMI divides your weight in kilograms by the square of your height in metres.
  • The standard adult categories are the same for women and men: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obese.
  • The healthy weight range shown is the weight that keeps your BMI between 18.5 and 24.9 for your height.
  • BMI does not measure body fat directly and does not account for muscle, pregnancy, or body-fat distribution.
  • Use it as a general screen and discuss any concerns with a healthcare professional.

62 kg, 1.65 m

Inputs
  • Weight (kg): 62
  • Height (m): 1.65

BMI = 62 ÷ 1.65² ≈ 22.8, which is in the normal-weight range. The healthy weight band for 1.65 m is about 50.4–67.8 kg.

Frequently asked questions

Is BMI different for women?
The formula and adult categories are the same for women and men. Women generally carry more body fat at a given BMI, but the cut-offs do not change.
What is a healthy BMI for a woman?
For most adult women, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight and 25 or above is overweight or obese.
Is BMI accurate during pregnancy?
No. BMI is not meant for use during pregnancy. Use a pre-pregnancy BMI and follow your provider's weight-gain guidance instead.
Does BMI account for muscle?
No. Very muscular or very lean women may get misleading BMI results, so consider body-fat or waist measurements alongside it.
How can I change my BMI?
Since adult height is fixed, BMI changes with weight. Gradual, sustainable changes to diet and activity are the safest approach.
