Body Fat Percentage using Body Adiposity Index Calculator(BAI)
Find Your Body Fat Percentage (BAI) using Height and Hip Measurements
BAI Formula and BAI Classification for Men and Women
BAI formula:
BAI = (hip circumference/(height)^1.5) - 18
hip circumference is in centimeters and height is in meters.
BAI classification for women:
| Age(years) | Underweight | Healthy | Overweight | Obese |
|---|---|---|---|---|
| 20-39 | < 21% | 21% to 33% | > 33% | > 39% |
| 40-59 | < 23% | 23% to 35% | > 35% | > 41% |
| 60-79 | < 25% | 25% to 38% | > 38% | > 43% |
BAI classification for men:
| Age(years) | Underweight | Healthy | Overweight | Obese |
|---|---|---|---|---|
| 20-39 | < 8% | 8% to 21% | > 21% | > 26% |
| 40-59 | < 11% | 11% to 23% | > 23% | > 29% |
| 60-79 | < 13% | 13% to 25% | > 25% | > 31% |
Recommended BAI Table for Men and Women covering Age Groups 20 to 39 years
Note: This is computed based on what is considered as 'Normal' or 'Healthy' BAI score for Men (8% - 21%) and for Women (21% to 33%) for Age group of 20 to 39 years.

BAI stands for Body Adiposity Index. It determines the overall fat percentage in the body using height and hip measurement.
BAI stands for Body Adiposity Index. It determines the overall fat percentage in the body using height and hip measurement.
BAI = ( hip circumference / ( height ) ^ 1.5) - 18. Hip circumference is in centimeters and height is in meters.

BAI can be measured with a tape in standing position. Wrap it around the largest part of the hip region for the hip circumference measurement. Note down the value in cms . For height, stand against a wall, and measure from top part of head to toe in straight position. Convert the cm or inches to meter. Apply the formula for BAI (hip circumference/(height)^1.5) - 18

BMI uses body weight to find the fat percentage. BAI does not use body weight but uses hip circumference to find the BAI. Both use height as the common parameter.

They are complementary to each other. Both have limitations and not the ideal most accurate measure but useful as a rough indicator of body fat percentage. Since BMI uses weight, it has the drawback of not being able to distinguish between muscle mass weight vs fat weight. Also BMI does not have age or gender specific classification. BAI was formulated to address age and gender specific classification.

Relative Fat Mass (RFM)- It uses height and waist circumference to compute the % of body fat. Waist to Hip Ratio (WHR) - It uses waist to hip ratio to find the fat distribution in the body (visceral fat vs subcutaneous fat). Body Mass Index (BMI) - It gives a measure of body fat based on height and weight measurements.

Yes, Adipose cells or tissue is referred to as body fat. They store fat as globules. Fat under the skin is Subcutaneous fat (thigh, hip and those under the skin). They are also referred as SAT - Subcutaneous Adipose Tissue. Visceral fat is the fat surrounding liver and other organs and is located deeper inside the body. They are also referred to as VAT - Visceral Adipose Tissue.
