Measuring body fat percentage is a key step in understanding our health and fitness. It gives us a clearer picture than just weight or BMI because it focuses on body composition - the ratio of fat to lean mass. In Australia, many people are becoming more aware of the importance of tracking body fat for better health outcomes. This post will guide you through the common body fat measurement methods, explain what different percentages mean, and offer practical advice on how to use this information effectively.
Common Body Fat Measurement Methods
There are several ways to measure body fat, each with its own advantages and limitations. Knowing these methods helps us choose the right approach for our needs.
1. Skinfold Calipers
Skinfold measurement involves pinching the skin and underlying fat at specific body sites and measuring the thickness with calipers. This method is:
Affordable and accessible
Quick to perform
Requires some skill for accuracy
It estimates body fat by using equations based on the thickness of skinfolds. However, it can be less accurate if not done correctly or if the person has very high or low body fat.
2. Bioelectrical Impedance Analysis (BIA)
BIA devices send a small electrical current through the body and measure resistance. Fat tissue resists electricity more than muscle, so the device estimates body fat percentage.
Non-invasive and easy to use
Available in scales and handheld devices
Results can vary based on hydration, food intake, and exercise
BIA is popular for home use but can be less reliable than professional methods.
3. Dual-Energy X-ray Absorptiometry (DEXA)
DEXA scans use low-level X-rays to differentiate between bone, fat, and muscle. This method is:
Highly accurate and detailed
Provides regional body fat distribution
Usually available in clinics or specialised labs
It is more expensive and less accessible but offers precise data for those serious about tracking body composition.
4. Hydrostatic Weighing
This method involves being submerged in water to measure body density. Fat is less dense than water, so the difference helps calculate body fat percentage.
Accurate but requires special equipment
Not widely available
Can be uncomfortable for some people
5. Air Displacement Plethysmography (Bod Pod)
Similar to hydrostatic weighing but uses air displacement instead of water. It measures body volume and calculates body fat.
Quick and comfortable
Accurate
Limited availability
Each method has its place depending on your goals, budget, and access to facilities. For many Australians, a combination of methods or regular tracking with BIA or skinfold calipers can provide useful insights.
Is 20% Body Fat Chubby?
Understanding what body fat percentages mean can be confusing. Is 20% body fat considered chubby? The answer depends on several factors including age, sex, and body type.
Body Fat Percentage Ranges
Generally, for adults:
Men:
- Essential fat: 2-7%
- Athletes: 8-13%
- Fitness: 14-17%
- Average: 18-24%
- High: 25% and above
Women:
- Essential fat: 10-15%
- Athletes: 16-20%
- Fitness: 21-24%
- Average: 25-31%
- High: 32% and above
At 20% body fat, a man is generally in the average range, not chubby. For women, 20% is often in the athlete or fitness range, which is quite lean.
Factors to Consider
Muscle mass: Someone with more muscle may look leaner at the same body fat percentage.
Fat distribution: Where fat is stored affects appearance and health risk.
Age: Body fat tends to increase with age naturally.
Health markers: Blood pressure, cholesterol, and glucose levels are important alongside body fat.
So, 20% body fat is not inherently chubby. It’s a number that needs context. Tracking changes over time and how you feel physically is more important than a single measurement.
Practical Tips for Measuring Body Fat Accurately
To get the most reliable results from body fat measurements, consider these practical tips:
Consistency is key: Measure at the same time of day, under similar conditions.
Hydration matters: Avoid measuring right after heavy exercise or dehydration.
Use the same method: Switching methods can cause confusing results.
Professional help: For skinfolds or DEXA, seek trained professionals.
Track trends, not single values: Focus on how your body fat changes over weeks or months.
If you want to track your progress, consider combining body fat measurements with other metrics like waist circumference, strength levels, and endurance.
Why Body Fat Percentage Matters More Than Weight
Weight alone doesn’t tell the full story. Two people can weigh the same but have very different body compositions. Body fat percentage gives us a clearer picture of health risks and fitness.
Health Implications
High body fat: Linked to increased risk of heart disease, diabetes, and some cancers.
Low body fat: Can affect hormone balance, immune function, and energy levels.
Balanced body fat: Supports metabolic health, physical performance, and longevity.
Fitness and Performance
Knowing your body fat helps tailor training and nutrition plans.
Athletes often aim for specific ranges to optimise performance.
Tracking body fat can motivate healthy lifestyle changes.
Longevity and Quality of Life
Maintaining a healthy body fat percentage supports mobility, reduces inflammation, and improves overall well-being as we age.
How to Use Body Fat Data to Improve Health
Once we have accurate body fat data, the next step is using it effectively.
Set Realistic Goals
Aim for gradual changes rather than quick fixes.
Focus on fat loss while preserving muscle mass.
Adjust goals based on age, lifestyle, and health status.
Nutrition Strategies
Prioritise whole foods rich in nutrients.
Balance macronutrients to support fat loss and muscle maintenance.
Stay hydrated and avoid excessive processed foods.
Exercise Recommendations
Combine resistance training with cardiovascular exercise.
Include flexibility and mobility work.
Track progress with body fat measurements every 8-12 weeks.
Monitor and Adjust
Use body fat data alongside other health markers.
Adjust nutrition and training based on progress.
Celebrate improvements in strength, energy, and well-being.
By understanding and applying body fat measurement methods, we can make informed decisions that support long-term health and fitness.

Taking the Next Step in Body Composition Awareness
Measuring body fat percentage is more than just a number. It’s a tool that helps us understand our bodies better and make smarter choices. Whether you use skinfold calipers, BIA devices, or advanced scans, the key is consistency and context.
We encourage you to explore the methods that suit your lifestyle and goals. Regular tracking, combined with balanced nutrition and exercise, can lead to meaningful improvements in health and performance.
Remember, body fat percentage is one piece of the puzzle. Embrace a holistic approach to wellbeing and enjoy the journey towards a healthier you.
