Body Fat Calculator for Women
Estimate your body fat percentage with healthy ranges made for women.
Your measurements
Body fat percentage is a far better measure of a woman's fitness than the scale or BMI alone, because it separates fat from the muscle and bone you want to keep. It also comes with ranges that are specific to women, which matters, because a healthy female body is not built like a male one.
Why women's ranges are different
Women carry more essential fat than men, the baseline fat the body needs for hormones and reproductive health. That is normal and healthy. It means a fit, lean woman has a higher body fat percentage than a fit, lean man, and comparing yourself to male charts is misleading.
Healthy body fat ranges for women
| Category | Body fat |
|---|---|
| Essential fat | 10 to 13% |
| Athletes | 14 to 20% |
| Fitness | 21 to 24% |
| Average | 25 to 31% |
How to measure
This calculator uses the US Navy method for women, based on your height and the circumference of your neck, waist, and hips. Keep the tape snug but not tight, measure at the same time of day, and take each reading twice for accuracy.
Going lower, safely
Chasing very low body fat has real downsides for women, including disrupted cycles and bone loss. A healthy, sustainable range beats an extreme one you cannot hold. SmaartCoach builds a plan that lowers fat while protecting your energy, cycle, and strength.
Frequently asked questions
What is a healthy body fat percentage for women?
Women naturally carry more essential fat than men. Typical ranges are athletes 14 to 20 percent, fitness 21 to 24 percent, and average 25 to 31 percent. Below about 13 percent can affect hormones and health.
Why do women have higher body fat than men?
Women need more essential fat for hormone production and reproductive health, so a healthy female body fat percentage is naturally several points higher than a healthy male one.
How do women measure body fat with a tape?
The US Navy method for women uses height plus the circumference of the neck, waist, and hips. Keep the tape snug and level, and measure at the same time of day.
Can body fat be too low for women?
Yes. Very low body fat can disrupt the menstrual cycle, weaken bones, and affect hormones. Extremely lean physiques are hard to maintain and not a healthy year-round goal.
