BMI Calculator with Frame Size and Gender

The body mass index — BMI — is a metric that doctors use to determine whether a patient is 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 body weight 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.

Wrist Size and Frame Size

Knowing your frame size enables you to determine a healthy weight range for your body based on your measurements. Since persons with larger wrists generally have larger frames, measuring the diameter of the wrist is frequently used to estimate the frame size.

  • A man with a medium frame, for example, is over five feet five inches tall and has a wrist circumference of 6.5 to 7.5 inches.
  • Women with a wrist circumference of 6.25 to 6.5 inches are considered to have a medium frame.
  • A woman with a wrist circumference of between 5.5 and 5.75 inches is considered to have a medium frame.
  • A lady with a medium frame has a height between 5’2″ and 5’5″ and a wrist size between 6″ and 6.25″.

Frame Size and Healthy Weight

At a higher weight, those with larger frames can be healthy than those with smaller frames. If you’re 5’7″ and have a medium frame, your ideal weight range is around 140 to 144 lbs. If you have a large frame, your ideal weight range is anywhere from 150 to 170 pounds.

Even at the same height, women should weigh less than males because of their smaller frames. When it comes to weight, a 5-foot-7-inch tall lady with a medium or large physique should weigh anywhere from 133 pounds to 147 pounds.

Evaluating BMI in Relation to Frame Size

Even if your weight is normal, if you have a body fat percentage of 20% as a man or 30% as a woman, you may be at a considerably increased risk of ailments including heart disease and type 2 diabetes. When assessing the health of your weight, your doctor may run a variety of tests, including BMI. A physical exam, blood pressure, cholesterol checks, and blood tests assist evaluate whether you’re healthy for your height and frame size, or if you’re at an increased risk of disease.

If you have a tiny frame size yet have a BMI that is above the usual range for your height, this could suggest that you have too much body fat. Additional testing and more in-depth body fat studies, such as body fat caliper measurements, bone density scans, and air displacement weighing, may help you assess your health.

Muscular Builds and BMI

For persons with a large frame or a muscular body, BMI is less accurate. For example, if you are exceptionally muscular, you may weigh a lot for your frame size since muscle is more dense than fat and takes up less space. However, having an abundance of muscle does not pose a health danger. Regardless of your frame size, most doctors can visually identify whether your high BMI is due to an abundance of muscle or fat.

A 5-foot-10-inch bodybuilder, for example, may weigh 200 pounds but have only 9 percent body fat. His BMI of 28.7 would put him in the overweight category, but his lean physique and active lifestyle put him at low risk of disease despite his relatively high BMI.
