Body Fat Percentage for Women
Women's bodies naturally store more fat than men's, partly as a requirement for fertility, so reference ranges for a "normal" body fat percentage differ clearly between the sexes. A body fat percentage that would count as high for a man can be entirely typical for a woman.
The calculator below is pre-set to female and shows the hip field, which the tape method needs for women but not for men.
How to measure your waist
Measure at navel level, tape horizontal, relaxed at the end of a normal exhale.
How to measure your neck
Measure just below the larynx, with the tape sloping slightly downward at the front.
How to measure your hip
Measure at the widest point, feet together.
Rounding to the nearest half centimetre (or quarter inch) is fine — it won’t meaningfully change the result.
Add your weight to also see fat mass and lean mass in the result.
No tape measure? Leave waist, neck and hip blank and we’ll estimate from height, weight and age instead.
Reference ranges for women
| Category | Range | What it means |
|---|---|---|
| Essential fat | 10–14% | The lowest level of fat the body needs for basic functions like hormone production. Staying here for long, especially without supervision, isn’t a healthy goal in itself. |
| Athletic | 14–21% | Common among competitive athletes and people with highly structured training and diet. Uncommon in the general population. |
| Fit | 21–25% | Common among people who train regularly without competing. Visible muscle definition is typical at this level. |
| Average | 25–32% | The most common level in the general population, and not in itself considered a health problem. |
| Above average | 32%+ | Above the range associated with lower health risk in population studies. It says nothing about any individual’s health on its own — only where the value falls relative to the reference population. |

How this method works
Developed by the US Navy (Hodgdon & Beckett, 1984), this formula estimates body fat percentage from height and the circumference of the waist, neck and, for women, hip. It needs nothing but a tape measure and typically lands within ±3.5 percentage points of a DEXA scan across most body types.
Frequently asked questions
Why is "normal" body fat higher for women than for men?
Female bodies need a higher share of essential fat for hormone production and fertility — roughly 10–14%, compared with 2–6% for men. That shifts the entire scale upward, not just the lower bound.
Do the reference ranges change after menopause?
Body composition often shifts after menopause, typically toward more fat around the waist and less lean mass, but the general reference ranges shown here apply to adult women broadly rather than by age band.
Do I need to measure my hip if I’m male?
No. The hip measurement is only used in the formula for women — waist and neck are enough for men.
