How to Measure Body Fat Percentage Without Using Calipers

Tracking body fat percentage is one of the best ways to monitor your fitness progress or weight loss efforts. Calipers are an effective and precise tool for measuring changes in body fat, but they can be difficult to use and require skill. If you are unable to measure skinfolds with calipers, don’t have calipers, or don’t know how to use them, alternative tools are available. Below are some methods for measuring body fat without using calipers.

Measure your height. Stand straight without shoes while measuring.

Measure your waist circumference. For women, measure at the smallest point of the waist, right at the waistline. For men, measure around the area of the navel. Avoid sucking in your stomach while measuring.

Measure your neck circumference. Place the tape measure just below the Adam's apple and slightly tilt it forward. Avoid tilting your neck up or bending it down while measuring.

For women, measure the hip circumference as well. The hip circumference is the widest point around the hips.

Plug your measurements into one of the formulas below, or use an online calculator to compute the result. Round off the result to get the body fat percentage.

• For men, in inches: %Body Fat = 86.010 * LOG (waist - neck) - 70.041 * LOG (height) + 36.76
• For men, in centimeters: %Body Fat = 86.010 * LOG (waist - neck) - 70.041 * LOG (height) + 30.30
• For women, in inches: %Body Fat = 163.205 * LOG (waist + hips - neck) - 97.684 * LOG (height) - 78.387
• For women, in centimeters: %Body Fat = 163.205 * LOG (waist + hips - neck) - 97.684 * LOG (height) - 104.912

Wear only underwear or swimwear during the measurement. For the most accurate results, it is best to avoid wearing clothes when measuring, or only wear thin clothing if necessary. To ensure consistency, you should wear the same clothing each time you measure.

Measure your waist. Wrap the measuring tape around your waist, right above your hip bones. Ensure the tape is snug against your skin, pulled taut, but not so tight as to cause discomfort.

• You may need to check in the mirror to ensure the tape is in the correct position and pulled tight.
• It’s important to measure in the same location each time and use the same type of measuring tape for consistency.

Diagnosing disease risk. Measuring your waist circumference not only provides an accurate body fat percentage but is also valuable for health monitoring.

• For non-pregnant women with a waist larger than 35 inches (89 cm), and for men with a waist larger than 40 inches (102 cm), there is an increased risk of obesity-related diseases such as hypertension and adult-onset diabetes.
• If you’re not pregnant and haven’t gained weight but notice your waist growing, you should consult a doctor for a checkup. There could be an underlying health issue.

Measure your height. When measuring, avoid wearing shoes, and ensure you are standing straight.

Weigh yourself. Use a properly calibrated scale to measure your weight, and you can record the results in pounds or kilograms.

Compare with the BMI chart. Find a reliable BMI chart, then match your height and weight to locate the intersection point. The number at this point represents your BMI, or body mass index.

• You can view an online BMI chart at here.
• Your BMI naturally tends to increase slightly as you age.
• For children and adolescents: BMI must be calculated using age- and gender-specific charts. Otherwise, the results may not be accurate.
• You can use online tools to calculate your BMI. Click on the link for adults and for children and adolescents to calculate.

Understand your BMI result. Your BMI represents the ratio of your height to your weight. Your body consists of fat, bones, blood, muscles, and various other tissues, all contributing to your weight and BMI. While BMI is not directly linked to your body fat percentage, it is a useful measure to assess whether you are underweight, normal, overweight, or obese. Below is the BMI categorization for adults:

• <18.5: Underweight.
• 18.5-24.9: Normal weight.
• 25-29.9: Overweight.
• > 30: Obesity.
• Some people may be classified as overweight due to having more muscle mass, even though they are not fat. After calculating your BMI, you can consult a doctor to interpret the result.
• If you are not exercising and gaining weight without building muscle, it could be due to an increase in fat.
• If you gain weight while exercising and eating healthy, most of the weight gain may be muscle mass with a small amount of fat.
• If you are losing weight, you might be losing both muscle and fat.
