The healthy BMI range for adult women is 18.5 to 24.9 at every age from 20 upwards. The World Health Organization uses the same BMI categories for women and men.<\/strong> What changes is how the number should be read: women naturally carry more body fat than men at the same BMI, some studies suggest a slightly higher BMI is not harmful in older age, and waist size (above 88 cm or 35 inches) adds information BMI misses. For girls under 20, BMI is judged against age-specific percentile charts instead.<\/p>\n

For women of South Asian, Chinese and some other Asian backgrounds, health agencies often use lower thresholds because risk of diabetes and heart disease rises at lower BMIs: overweight from 23 and obesity from 27.5. See WHO BMI categories explained<\/a>.<\/p>\n

The official categories don’t change with age for adults. If you’re over 65, discuss your weight with a doctor rather than aiming for a lower BMI by itself.<\/p>\n

How to Check Your BMI as a Woman<\/h2>\n
    \n
  1. Measure your height without shoes and your weight first thing in the morning.<\/li>\n
  2. Enter both in the free BMI Calculator<\/a>. It shows your BMI and your healthy weight range straight away.<\/li>\n
  3. Add your age and select female to see an estimated body fat percentage and daily calorie needs.<\/li>\n
  4. Measure your waist at the level of your belly button; above 88 cm (35 inches) suggests higher health risk even with a normal BMI.<\/li>\n<\/ol>\n
