BMI Calculator for Women
Calculate BMI and see the healthy weight range, with the specific caveats that apply to women's body composition.
Does BMI differ for women?
The formula and the category boundaries are identical for both sexes — this is one of BMI's known weaknesses rather than a feature. Women carry more essential body fat than men (roughly 10–13% against 2–5%), so the same BMI represents a different body composition. Body fat percentage and waist-to-hip ratio give women a clearer picture than BMI alone.
When BMI is misleading for women
During pregnancy BMI stops being meaningful and gestational weight gain guidelines take over. After menopause, fat redistributes towards the abdomen without necessarily changing weight, so BMI can hold steady while metabolic risk rises — which is exactly what waist measurement catches and BMI does not.
The formula
BMI = weight(kg) / height(m)²
Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.

BMI Calculator for Women — frequently asked questions
What is a healthy BMI for a woman?
The same 18.5–24.9 range used for everyone. The WHO does not publish separate cut-offs by sex, though several researchers argue it should.
Should I use a different BMI chart when pregnant?
No. BMI is not used during pregnancy. Your pre-pregnancy BMI sets the recommended weight-gain range, which is what your midwife will track instead.
Is this bmi calculator for women free to use?
Yes. Every calculator on the site is free, needs no sign-up, and runs entirely in your browser, so your figures never leave your device.
How accurate is the result?
The maths is exact for the formula shown on the page. Accuracy in the real world depends on your inputs and on assumptions the formula cannot see, so treat the output as a well-grounded estimate rather than a quote.
Can I use it on my phone?
Yes. The page is responsive, weighs a few kilobytes and works offline once loaded, so it behaves the same on a phone as on a desktop.
