Determining Desirable Body Weight

If the tables are not available, a simple way to determine desirable body weight is as follows :

Women :

100 pounds of body weight for the first 5 feet of height, 5 pounds for each additional inch.

Men :

106 pounds of body weight for the first 5 feet of height, 6 pounds for each additional inch.

Add 10% for a large frame size, and subtract 10% for a small frame size.

Desirable Weight Ranges - Determining Frame Size

To determine the body frame size, measure the wrist with a tape measure and use the following chart to determine whether the person is small, medium, or large boned. Using the formula, you can determine your desirable body weight. The formula provides an approximate desirable body weight for height. The weight range can vary on an individual basis.

Women Men
Height Under 5'2"
Small = wrist size less than 5.5"
Medium = wrist size 5.5" to 5.75"
Large = wrist size over 5.75"
Height Over 5' 5"
Small = wrist size 5.5" to 6.5"
Medium = wrist size 6.5" to 7.5"
Large = wrist size over 7.5"
Height 5'2" to 5' 5"
Small = wrist size less than 6"
Medium = wrist size 6" to 6.25"
large = wrist size over 6.25"
