Body Fat Percentage Calculator (with pictures)

Use this calcount Body fat Percentage Calculator to estimate how much of your body is made of fat. Then, read on to find out what your body fat percentage result means. We’ve included some pictures of people with progressively higher fat percentages, so you can get an idea of how different body compositions appear.

Body Fat Percentage

People measure their body fat percentage as a fitness indicator and aesthetic target. Fat is a store of energy and the main component of excess body weight. Too much fat can cause obesity and its associated poor health outcomes. Too little fat can compromise the immune system and prevent normal body function. To calculate your body fat percentage, divide the weight of your fat by your total body weight, then multiply by 100.

Body Fat Examples

You can’t accurately calculate your body fat percentage by simply looking in the mirror, but it is useful to see some examples. You can compare your appearance to the pictures of women and men below to get an idea of what your own Body Fat Percentage is.

15% Body Fat Percentage usually means Underweight Woman

If you are a woman and your body fat percentage is about 15% (12-19%), you are probably underweight. Anything below 12%, for example 10 percent body fat, indicates severe underweight and probable malnourishment. This reasoning does not apply to professional body builders and other athletes who may have a much higher proportion of muscle relative to fat.

20% to 30% Body Fat usually indicates a Normal Weight Woman

Between 20 and 30 percent body fat is considered normal and healthy for women.

Woman Body Fat percentage 31%

A Woman with 31% to 36% Body Fat may be Overweight

Women with between 31 to 36 percent body fat may be classed as Overweight.

Obese Woman, 37-42% Body Fat

The obesity level for women starts at 37% body fat percentage.

Body fat percentage woman 49%

Obese Class 2 Woman

The second level of obesity for women sits between 43 and 49% body fat.

Obese Class 3 Woman

A woman with a body fat percentage above 49% is considered to be Class 3 obese.

Less than 9% equals Underweight Man

Unless the man with less than 9% body fat is a bodybuilder or athlete, he is probably underweight.

Normal Weight for a Man includes 9-18% Body Fat Percentage

For men, a body fat percentage between 9% and 18% is considered normal.

Body fat percentage man 25%

An Overweight Man has between 19 and 25% Body Fat

The level between Normal Weight and Obesity is termed Overweight, and usually means that a man has 19% to 25% body fat.

Obese Man starts at 26% Body Fat

Obesity in men starts from 26% body fat.

Obese Class 2 Man

From 33% to 39% body fat, men are considered to be in the second Obesity category.

Body fat percentage man 40%

Obese Class 3 Man has 40% or more body fat

The third class of obesity in men starts at 40%.

How is Body Fat Percentage Calculated?

There are at least ten different techniques used to measure body fat percentage, and none of them are perfectly accurate. It is really hard to get a certain result, because fat happens to be intimately connected to just about every type of body tissue imaginable. You just cannot easily say (without opening things up and looking inside) where the fat stops and the other tissue starts. The best way is to find a person’s body density then calculate for relative densities of different body tissues.

However, the challenges has not stopped scientists from trying. The ten main methods for calculating body fat percentage are:

  1. Underwater Weighing (a.k.a. Hydrostatic Weighing), where body density is estimated by water displacement.
  2. Whole-body Air Displacement Plethysmography, a way to measure body density with a machine rather than having to submerge a person in water.
  3. Near-infrared Interactance, a light is shone onto a limb to see how the beam is reflected and absorbed.
  4. Dual energy X-ray Absorptiometry (a.k.a DXA, or DEXA) uses x-rays to compare body tissues.
  5. Body Average Density Measurement, a formula is used to estimate body density, based on volume and mass.
  6. Bioelectrical Impedance Analysis sends an electric current through the body to measure relative conductivity and thus body composition.
  7. Skinfold Test (a.k.a. Pinch Test) is where body parts are gripped by a pair of callipers to see how much subcutaneous fat rests under the skin.
  8. Ultrasound is used to detect how thick subcutaneous fat is.
  9. Height and Circumference formulas, where neck, waist, and hip measurements are compared to height.
  10. From BMI. This is the method our calcount Body Fat Percentage Calculator uses. A formula is applied to BMI to arrive at an accurate estimate of body fat percentage. Since this method relies on BMI, it is subject to the same limitations BMI has. See our BMI Calculator to read them.
