Body Fat Percentage Chart for Men and Women by Age
The body fat percentage chart almost everyone has in mind comes from the American Council on Exercise. Five bands, one set of numbers for men and one for women, and the same rows whether you are 22 or 72. Age sits outside it entirely.
The ACE chart
- Essential fat: men 2 to 5%, women 10 to 13%
- Athletes: men 6 to 13%, women 14 to 20%
- Fitness: men 14 to 17%, women 21 to 24%
- Average: men 18 to 24%, women 25 to 31%
- Obese: men 25% and above, women 32% and above
Women sit roughly eight to ten points above men in every band, and conditioning has nothing to do with it. The gap is breast tissue, reproductive organs and the fat stored around them. Training leaves it exactly where it is.
Where age comes in
Several clinical charts do adjust for age, because body fat climbs over the decades even when your weight holds steady. One widely cited set of healthy ranges comes from Gallagher and colleagues in the American Journal of Clinical Nutrition, and it runs roughly like this.
- Men 20 to 39: 8 to 19% healthy, 20 to 24% overweight, 25%+ obese
- Men 40 to 59: healthy stretches to 11 to 21%, with 22 to 27% overweight and 28%+ obese
- Men 60 to 79: 13 to 24% healthy, 25 to 29% overweight, 30%+ obese
- Women 20 to 39: 21 to 32% healthy, 33 to 38% overweight, 39%+ obese
- Women 40 to 59: healthy stretches to 23 to 33%, with 34 to 39% overweight and 40%+ obese
- Women 60 to 79: 24 to 35% healthy, 36 to 41% overweight, 42%+ obese
Look at how much wider those healthy ranges run than the ACE fitness band. The two charts answer different questions. ACE describes conditioning, Gallagher describes health risk, and a 45 year old man at 20% is at risk of very little.
Average and healthy are two different words
This one trips people up constantly. The average American man carries around 28% body fat and the average American woman around 40%. Both of those land in the ACE obese band. What 30% body fat looks like sits between the two figures. What 30% body fat looks like sits between the two figures. What 30% body fat looks like sits between the two figures. What 30% body fat looks like sits between the two figures. Being average here should worry you, not reassure you.
When a chart says average, find out which average it means: the statistical middle of the population, or the healthy middle. ACE means the second, and it sits well below what the population carries.
Reading your own number against the chart
Pick your row by sex first and age second, then find your figure. If you have no figure yet, the body fat calculator will give you one from a tape measure in about a minute. Guessing from the mirror is the least reliable method there is, and people generally guess two to four points low.
Then use that same method every time. A skinfold caliper and a bathroom scale can land five points apart on the same person on the same morning, so your direction of travel across three months tells you more than today’s absolute value.
What the chart leaves out
Location, first. Fat around your organs carries far more metabolic risk than fat on your hips and thighs, so two people at 28% can sit in very different places. A tape measure at the navel catches that, and visceral fat and why it matters more explains the difference.
Muscle, second. Two men at 18% with a 15 kg gap in lean mass read identically here. If you train, track your lean mass alongside the percentage and you will see whether a diet is working or quietly costing you, which is what body recomposition is about.
If your figure came from BMI instead of a measurement, treat it as a rough guide. What BMI measures covers where that estimate breaks.
