Our body fat calculator was developed and tested in cooperation with many athletes from different sports. This is to ensure that our body fat calculator always gives you the best results.
Take a selfie of yourself, preferably in your gym outfit. You will get the best results if you take selfies with your upper body bare so that the evaluation is most accurate.
Your image is processed by our AI and examined for certain patterns that provide information about what body fat percentage you have. Our model was trained with over 100,000 verified example images to deliver the most accurate results possible.
As soon as your data is processed, you will receive the result of your body fat measurement. Here you will find out what percentage of body fat you have and how likely your result is.
For the best possible results, we recommend uploading different images several times to avoid incorrect results. If your result differs greatly from what you expected, try another photo against a different background with sufficient lighting.
The ideal body fat percentage varies depending on gender and age. For women, a healthy range falls between 21% and 35%, while for men, it ranges from 8% to 24%.
As we age, our metabolism changes—fat mass tends to increase while muscle mass decreases. This means that younger adults typically fall on the lower end of the range, while body fat percentage gradually increases over time.
These reference values are based on a study by Dympna Gallagher et al., which introduced a new method for determining healthy body fat percentages. The study links recommended Body Mass Index (BMI) values with predicted body fat percentages.
There are precise methods to measure body fat, such as Dual-Energy X-ray Absorptiometry (DEXA), air-displacement plethysmography, and hydrostatic weighing. However, these techniques can be costly and impractical for regular use. A more convenient alternative is using a body fat calculator, which provides a quick and reasonable estimate with simple tools at home.
All you need is a flexible measuring tape or a high-quality skinfold caliper.
The calculator allows you to choose from different estimation methods via a drop-down menu. If you already know your body fat percentage and trust its accuracy, you can manually enter the value and compare it with the provided charts.
The BMI method requires only your height and weight. The U.S. Navy and Covert Bailey methods rely on circumference measurements using a measuring tape. Meanwhile, the Jackson-Pollock and Durnin-Womersley methods require a skinfold caliper to measure skinfold thickness at specific body sites.
The BMI method is the least precise way to estimate body fat, offering only a rough approximation. It is best suited for those who prefer not to use measuring tapes or skinfold calipers.
This approach calculates body fat percentage based on average values obtained from a sample of a sedentary population with similar age, sex, and BMI characteristics. While it provides a general idea, it does not account for variations in muscle mass or body composition.
For people, but especially for athletes, it can be very important and interesting to know your own body fat percentage. Your body fat percentage can give you valuable information about what you could improve in your everyday life, training and diet.
Our body fat calculation makes it easy for you to track your fitness progress so you don't lose sight of your goals and get an honest assessment of your body fat percentage.
For many people, it is important to see results from their work and hours spent in the gym. Our body fat calculator gives you exact numbers that show your progress and therefore motivate you to work even harder on your goals.
Knowing your own body fat percentage can help you prevent diseases such as heart disease, diabetes, and hypertension. These diseases are said to be directly related to body fat percentage.
The U.S. Navy and Covert Bailey methods use circumference measurements to estimate body fat reliably and easily. A flexible, non-stretchable measuring tape is required to measure specific body areas. All measurements should be taken directly on the skin, ensuring the tape is level with the floor and applies consistent tension—snug but not tight enough to compress soft tissues. For accuracy, take measurements at the same time of day, before any physical activity, and while wearing light clothing without shoes.
Developed by the U.S. Navy, this method calculates body fat percentage using body circumference measurements. It is designed to ensure service members meet required body fat standards.
The U.S. Navy method has an accuracy of approximately ±3.5% for most individuals.
Named after fitness expert Covert Bailey, this method is one of the more recent approaches to estimating body fat percentage. It is widely used and considered highly accurate for most people.
According to Bailey, this method provides results within ±2.0% of those obtained from hydrostatic weighing (also known as an immersion test).
Skinfold measurements, commonly used by personal trainers, estimate body fat percentage using calipers. Proper technique requires some training, but when performed correctly, this method can estimate body fat within ±3.5% of actual composition. Accuracy increases with the number of sites measured.
A simple, self-administered method that works well for people with an average build but underestimates body fat for lean athletes.
This method measures four sites, making it slightly more reliable than the three-site method. However, it may still be inaccurate for very lean individuals.
The most accurate of the Jackson-Pollock methods, measuring seven different sites for both men and women.
A widely used method, though it overestimates body fat in very fit individuals.
Each method varies in accuracy depending on body type, fitness level, and measurement precision. Choose the one that best fits your needs and equipment availability.
Your body fat percentage results will be displayed in charts based on guidelines from the American Council on Exercise (ACE), the World Health Organization (WHO) / National Institutes of Health (NIH), and the American College of Sports Medicine (ACSM).
The charts also include a weight column that provides an estimated weight range for each body fat percentage category. This allows you to determine the approximate weight needed to fall into your desired range. However, these estimates assume that any weight gain or loss primarily affects body fat while keeping lean body mass constant. In reality, both lean body mass and fat mass fluctuate, though lean mass tends to change more gradually.
To stay on track, it’s advisable to recalculate your body fat percentage periodically, especially as you gain or lose weight. If needed, adjust your target weight accordingly. When following a low-calorie diet, you can help preserve muscle mass by incorporating strength training exercises and increasing protein intake.
For many people today, it is important to improve their fitness. An important indicator for a healthy and efficient body is the body fat calculation. This value provides information that goes beyond normal weight.
The body fat percentage indicates the amount of fat tissue in relation to your total body composition. It is an important measurement that is important for making basic statements about general health and for preventing many diseases.
Our Body Fat Calculator utilizes advanced algorithms and data processing techniques to provide accurate estimates of your body fat percentage. While it may not be as precise as laboratory methods, it offers a reliable indication of your body composition for most individuals.
It's always recommended to consult with a healthcare professional before making significant changes to your fitness or nutrition regimen, especially if you have underlying medical conditions or special circumstances. Our calculator provides general estimates and may not be suitable for everyone.
The frequency of measuring your body fat percentage depends on your individual goals and preferences. For most people, taking measurements every few weeks or once a month is enough to track progress and adjust your fitness plan accordingly.
Our body fat calculator is designed primarily for adults and may not be appropriate for children or teenagers due to their distinct body compositions. To measure adolescents and children, you should always consult a doctor or specialist and have a professional body fat measurement taken.
The data protection of our users is our top priority. We do not store or evaluate your data. The data is only used to calculate your body fat percentage.
