Choose Your Measurement Method

Select from three accurate calculation methods based on the measurements you can take:

• Navy Method: Uses body circumference measurements (most accessible)
• BMI Method: Uses height and weight (quickest but least precise)
• Skinfold Method: Uses caliper measurements (most accurate when done properly)

Gather Your Measurements

For Navy Method: You'll need a flexible measuring tape to measure:

• Height (without shoes)
• Neck circumference (below the larynx)
• Waist circumference (at navel for men, narrowest point for women)
• Hip circumference (women only, widest point)

For Skinfold Method: Use calipers to measure thickness at:

• Chest (men) or triceps (women)
• Abdominal
• Thigh

Enter Your Information

Fill in all required fields in your chosen calculator:

• Select your gender (formulas differ for men and women)
• Enter your age (some methods use age in calculations)
• Input all measurements in the specified units (cm or mm)
• Be as precise as possible for accurate results

Tips for Best Results

• Take measurements in the morning before eating
• Measure at the same time each day for consistency
• For circumference methods, ensure tape is snug but not compressing skin
• For skinfold methods, take multiple readings at each site and average them
• Consider professional measurements for baseline data
