Body Fat Percentage Chart Explained
Body Fat Percentage Chart: Age, Sex & Fitness Level Explained
Updated June 2025
Keeping tabs on your body fat isn’t just a vanity metric—it’s a window into heart health, metabolic efficiency, and even hormone balance. But once you have a number, the next question is inevitable: Is that good, bad, or somewhere in-between?
This guide breaks down the latest research-backed body-fat percentage charts by age and sex, shows you how different measurement methods influence those numbers, and—crucially—explains what to do with the information.
Quick take: For most adults under 60, an acceptable body-fat range is 14–27 % for men and 21–34 % for women. If you fall outside that band, keep reading for context, caveats, and action steps.
How to Read a Body Fat Percentage Chart
Unlike BMI, which only divides weight by height, body-fat charts rely on body composition—the relative amounts of fat, lean tissue, and bone.
The American Council on Exercise (ACE) and CDC supply the most-referenced cut-offs.
Why body-fat ranges differ by sex
• Biology: Women need more essential fat (≈10–13 %) for fertility and hormonal health, while men can function on as little as 2–5 % ACE.
• Fat distribution: Men store proportionally more visceral (belly) fat, while women carry more subcutaneous fat; excess visceral fat is strongly linked to higher risks of heart disease, stroke, and type 2 diabetes CDC – Preventing Chronic Disease.
• Aging: After around 40, average body-fat percentage tends to increase with age as muscle mass declines—a process called sarcopenia—unless countered with resistance training StatPearls – Sarcopenia. See our strength-training guide for healthy aging.

| 30–39 | 2–5 % | 6–14 % | 15–25 % | ≥26 % |
| 40–49 | 3–6 % | 7–15 % | 16–26 % | ≥27 % |
| 50–59 | 3–7 % | 8–16 % | 17–27 % | ≥28 % |
| 60+ | 4–8 % | 9–17 % | 18–28 % | ≥29 % |

Body Fat Percentage Chart for Women
| Age Group | Essential | Athletic / Fit | Acceptable | Obese |
|---|---|---|---|---|
| 20–29 | 10–13 % | 14–20 % | 21–31 % | ≥32 % |
| 30–39 | 10–14 % | 15–21 % | 22–32 % | ≥33 % |
| 40–49 | 11–15 % | 16–22 % | 23–33 % | ≥34 % |
| 50–59 | 12–16 % | 17–23 % | 24–34 % | ≥35 % |
| 60+ | 13–17 % | 18–24 % | 25–35 % | ≥36 % |

Ways to Measure Body Fat—and Why Results Differ
The chart values above assume accurate body-fat measurement. Yet readings can swing several percentage points depending on the tool you pick and even the time of day you test. Below is a deeper dive into common methods, their typical error margins, and how those inaccuracies can change where you land on the chart.
| Method | Typical Error | What It Measures | When It Skews High | When It Skews Low |
|---|---|---|---|---|
| DEXA Scan | ±1–2 % | Total & regional fat, lean, bone, visceral fat | Presence of unremoved metal objects in the scan field (deviation from protocol) | Rare—tight quality control |
| Hydrostatic Weighing | ±2–3 % | Body density via underwater weighing | Incomplete water exhalation | Strong swimming skills (less trapped air) |
| BIA Smart Scale | ±3–6 % | Electrical impedance—infers composition from water content | Post-workout dehydration | Post-shower (wet feet conduct better) |
| Skinfold Calipers | ±3–5 % | Pinches subcutaneous fat at set sites | Inexperienced tester compressing skin | Very lean athlete with minimal pinch |
| Navy Circumference Formula | ±4–6 % | Tape measures neck, waist, hips | Large meal or bloating | Morning fasted, tall individuals |
How measurement error affects your chart category
Imagine a 35-year-old man whose true body fat is 25 % (upper end of “acceptable”). A dehydrated BIA reading might under-report by 3 %, placing him at 22 %—comfortably in the middle of “acceptable.” Conversely, a sloppy skinfold test could over-report by 4 %, bumping him into the obese threshold.
That’s why consistency and method choice matter. If precision is critical—say, you’re an athlete tracking marginal gains or a patient monitoring visceral fat—DEXA’s lower error range keeps category shifts genuine, not just statistical noise.

What Your Numbers Mean for Health
• Below Essential (🚩): Possible hormone disruption, low energy, impaired immunity. Increase nutrient intake and dial back extreme deficits.
• Athletic / Fit: Typically linked to lower visceral fat and improved insulin sensitivity—research in Diabetes Care found that higher body fat correlates with lower insulin sensitivity Diabetes Care.
• Acceptable: Common for the average U.S. adult. Health risk depends heavily on visceral fat—DEXA can separate the two.
• Obese Range (⚠️): Carrying excess body fat—especially around the waist—raises the likelihood of heart disease, type 2 diabetes, and sleep apnea. Research shows trimming even five percentage points of body fat can meaningfully lower these risks Harvard Health – Visceral Fat.
Expert Q&A
Q: Do women need higher body fat for hormones?
A: Yes. Dropping below ~15 % can disrupt estrogen production and menstrual cycles. One review found amenorrhea common in women with body-fat levels under 17 % Frisch, 1990. Aim for the athletic range, not essential, unless under medical supervision.Q: How often should I re-test?
A: Every 8–12 weeks is ideal—long enough for measurable change, soon enough to pivot.Q: I’m “skinny-fat.” My BMI is normal but, as a 35-year-old man, my body fat is 26 %. What now?
A: At 26 %, you’re in the obese range for your age group. Focus on resistance training to add lean mass, keep protein high, and monitor calories to reduce visceral fat. Check out our Skinny Fat Transformation Plan.
Evidence-Based Strategies to Shift Your Body Fat Percentage
- Lift weights 2–4×/week. Muscle is metabolically active and helps keep body fat in check.
- Eat 25–35 % of calories from protein. Protein supports muscle repair; find ideas in our guide to 25 High-Protein Snacks.
- Sleep 7–9 hours. Chronic sleep loss elevates cortisol and visceral fat accumulation Sleep Foundation – Sleep & Weight.
- Mix in HIIT. Short, intense bursts can reduce visceral fat more effectively than steady-state cardio Journal of Obesity – HIIT Meta-analysis.
- Track with data, not guesswork. Repeat DEXA or other valid method every quarter.
The Bottom Line
A body-fat percentage chart is only useful if you measure accurately and act on the insights. Whether you’re chasing athletic definition or simply lowering health risks, a concrete number empowers smarter training and nutrition choices.
