BMI Calculator with Frame Size and Gender

The body mass index — BMI — is a metric that doctors use to determine whether a patient is an underweight, overweight, or normal weight. The size of your body frame is not taken into account when calculating your BMI; instead, you can determine your BMI using your height and weight. Because the BMI evaluation does not take into account body composition or gender differences, its accuracy is dubious.


Calculating Weight in Relation to Height for Men and Women

If you’re unsure of your optimal body weight for your height and build, use our Ideal Body Weight Calculator to determine your ideal body weight.

Simply enter your gender (female/male), height, and frame size into the weight calculator, and the weight calculator will calculate your ideal body weight for your height. The body weight is specified in both pounds and kilograms.
Today, a more generally used metric for determining ideal body weight is the body mass index (BMI). The BMI is believed to be a more accurate indicator of total body fat than height and weight measures alone.

BMI Calculator with Frame Size and Gender and Age

Height, sex, age, body shape, body type, and exercise level all influence ideal body weight (IBW). Your IBW is a range since bodyweight fluctuates with various factors. A sex-specific equation can be used to compute your IBW. Men use 106 pounds for the first 60 inches (5 feet) of height, then add 6 pounds for every inch over 5 feet. Women start at 100 pounds and add 5 pounds for an inch above 5 feet. If you’re under 5 feet tall, start with 100 pounds and subtract 2 pounds per inch.

IBW = 106 + (10 X 6) = 166 pounds for a 5’10” male.

IBW = 100 + (8 X 5) = 140 lbs for a 5’8″ lady.

It depends on your body frame size. The wrist measurement method is quick and easy. Wrap your thumb and middle finger around your wrist above the joint. If the fingers overlap, you’re petite. If they just meet, you’re a medium. If your thumb and finger don’t contact, you’re enormous.

The IBW is calculated for a medium-framed adult. A large-framed adult will add 10% to the IBW, whereas a small-framed adult will subtract 10%.

For a 6 foot tall woman, IBW = 100 + (12 X 5) = 160 pounds. Her IBW is 160-176 pounds.

Determining desirable body weight for height for men and women

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

Determining frame size to calculate ideal body weight:

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.


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 5’2″ to 5′ 5″

small=wrist size less than 6″
medium=wrist size 6″ to 6.25″
large=wrist size over 6.25″

height over 5′ 5″

small=wrist size less than 6.25″
medium=wrist size 6.25″ to 6.5″
large=wrist size over 6.5″


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″

Using the above formula, you can calculate your desirable ideal body weight for both males and females. The formula provides an average body weight for height and frame. The weight range can vary on an individual basis and between men and women.

These weight tables are only appropriate to use with adults. For children, the height, weight, and head circumference should be measured and plotted in relationship to age on a growth chart at each well-child check from 2 weeks through 3 years of age. After age 3, only the height and weight are measured and recorded. Each individual growth measurement is not that helpful to the pediatrician, but the pattern of growth over time is extremely important.

Ideal Diet Chart According to Weight and Age

Use our diet chart to determine your ideal weight and frame size. The weight loss calculator uses these two factors when determining your weight loss results. If you are between two heights, round your height down to best determine your ideal weight.
