Body Fat Percentage Chart for Men and Women
Share
Body-fat reference ranges differ by sex and rise with age, and no single "ideal" number exists. The ranges below are the widely published descriptive categories from the American Council on Exercise and ACSM's normative data, reproduced with sources. Read them as population reference bands, not as health targets—and remember that a home bioimpedance scale typically reads within 3–5 percentage points of a DEXA scan, which is wider than the gap between two adjacent bands.

Why the number rises with age
Body composition shifts across adulthood: muscle mass declines gradually from roughly the fourth decade, while fat mass tends to rise, so the same body-fat percentage sits differently in the population distribution at 25 and at 55. Age-banded percentile tables exist in the ACSM normative data and are worth reading alongside the categories above rather than instead of them.
What the measurement error actually means
This is the part reference charts leave out, and it changes how much weight to put on your figure.

A home reading of 27% is consistent with a true value somewhere between roughly 22% and 32%, which spans three of the five categories above. That is why the trend matters and the single number does not: the error is largely consistent for the same person under the same conditions, so the *direction* of change over weeks is reliable even when the absolute figure isn't.
How to read your own trend properly
- Same time of day, same conditions, bare dry feet, before eating or drinking.
- Weekly, not daily. Daily readings track hydration, not composition.
- Compare seven-day averages across a month, from never reading to reading.
- Expect the figure to move with salt, alcohol, training load, and sleep—all of those change body water.
- Don't use bioimpedance at all if you have a pacemaker or another implanted electronic device.
Frequently asked questions
Q. What is a normal body fat percentage?
A. Published descriptive categories put the average range at 25–31% for women and 18–24% for men, with lower bands for fitness and athlete populations. These are population reference categories rather than health targets, and they shift with age.
Q. What's a healthy body fat percentage for my age?
A. There is no single healthy figure, and we can't give you one—reference tables describe how a population distributes, not what any individual should aim for. Body fat naturally rises with age as muscle mass declines. A doctor is the right person to interpret your figure in context.
Q. Why is women's body fat percentage higher than men's?
A. Essential fat—the amount required for normal physiological function—is higher in women, around 10–13%, compared with 2–5% in men, largely because of reproductive and hormonal function. Every reference band therefore sits higher.
Q. How accurate is a home body fat scale?
A. Typically within 3–5 percentage points of a DEXA scan for any single reading. Because that error is fairly consistent for the same person under the same conditions, the trend over weeks is far more reliable than the individual number.
Q. Can I lower my body fat percentage quickly?
A. We can't advise on that—it's a question for a doctor or a registered dietitian, not a scale manufacturer. What we can say is that short-term swings in the figure on any home scale are usually hydration, not composition.
