Check you weight at BMI Calculator

Body Mass Index (BMI) is a number calculated from a person’s weight and height. BMI provides an indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

Women tend to believe they look their best at values between 20 to 22 and men are usually satisfied with a BMI of 23 to 25. If your BMI  is between 17 to 22, your life expectancy is longer than average. You don’t need to lose weight. If your BMI is between 23 and 25, you are not considered overweight by most people.  But if your BMI is 26 or more, that’s not good.

What is the waist circumference?

Waist circumference is the distance around your natural waist (just above the navel). If your BMI is greater than or equal to 25 kg/m², your goal for waist circumference is less than 40 inches if you’re a man and less than 35 inches if you’re a woman.

What is the body mass index (BMI)?

Body mass index assesses your body weight relative to height. It’s a useful, indirect measure of body composition because it correlates highly with body fat in most people. Weight in kilograms is divided by height in meters squared (kg/m²). In studies by the National Center for Health Statistics,

• BMI values less than 18.5 are considered underweight.
• BMI values from 18.5 to 24.9 are healthy.
• Overweight is defined as a body mass index of 25.0 to less than 30.0. A BMI of about 25 kg/m² corresponds to about 10 percent over ideal body weight. People with BMIs in this range have an increased risk of heart and blood vessel disease.
• Obesity is defined as a BMI of 30.0 or greater (based on NIH guidelines) — about 30 pounds or more overweight. People with BMIs of 30 or more are at higher risk of cardiovascular disease.
• Extreme obesity is defined as a BMI of 40 or greater.

Some well-trained people with dense muscle mass may have a high BMI score but very little body fat. For them, the waist circumference, the skinfold thickness or more direct methods of measuring body fat may be more useful measures.

How do you find your BMI risk level?

1. Use a weight scale on a hard, flat, uncarpeted surface. Wear very little clothing and no shoes.
2. Weigh yourself to the nearest pound.
3. With your eyes facing forward and your heels together, stand very straight against a wall. Your buttocks, shoulders and the back of your head should be touching the wall.
4. Mark your height at the highest point of your head. Then measure your height in feet and inches to the nearest 1/4 inch. Also figure your height in inches only.
5. Find your height in feet and inches in the first column of the Body Mass Index Risk Levels table. The ranges of weight that correspond to minimal risk, moderate risk (overweight) and high risk (obese) are shown in the three columns for each height.

Height	Minimal risk (BMI under 25)	Moderate risk (BMI 25–29.9) Overweight	High risk (BMI 30 and above) Obese
4’10”	118 lbs. or less	119–142 lbs.	143 lbs. or more
4’11”	123 or less	124–147	148 or more
5’0	127 or less	128–152	153 or more
5’1″	131 or less	132–157	158 or more
5’2′	135 or less	136–163	164 or more
5’3″	140 or less	141–168	169 or more
5’4″	144 or less	145–173	174 or more
5’5″	149 or less	150–179	180 or more
5’6″	154 or less	155–185	186 or more
5’7″	158 or less	159–190	191 or more
5’8″	163 or less	164–196	197 or more
5’9″	168 or less	169–202	203 or more
5’10”	173 or less	174–208	209 or more
5’11”	178 or less	179–214	215 or more
6’0″	183 or less	184–220	221 or more
6’1″	188 or less	189–226	227 or more
6’2″	193 or less	194–232	233 or more
6’3″	199 or less	200–239	240 or more
6’4″	204 or less	205–245	246 or more

To calculate your exact BMI value, multiply your weight in pounds by 703, divide by your height in inches, then divide again by your height in inches.

To Your Health: Getting the facts on your child’s BMI

Published: Tuesday, September 14, 2010

By Annie Linton, M.Ed

Congress has officially proclaimed September 2010 as the first-ever Childhood Obesity Awareness Month.

We are all becoming painfully aware that pediatric and adolescent obesity is epidemic to our nation. According to the CDC (Center for Disease Control and Prevention), more than one third of U.S. adults — more than 72 million people — and 16 percent of U.S. children are obese.

Since 1980, obesity rates for adults have doubled and rates for children have tripled. The consequences of obesity make our children at risk for adult-like disease such as hypertension (high blood pressure), Type 2 diabetes, orthopedic and joint problems, cardiovascular disease and cirrhosis of the liver, as well as psychological ailments associated with severe weight gain.

With this being said, the Pennsylvania Department of Health’s (DOH) annual school health screening procedures now include calculating body mass index (BMI) to help track students’ growth patterns and identify potential weight-related health problems.

For those not familiar with the term, BMI is basically a measurement using height and weight. BMI = weight (kg) / height (m)Ç BMI does not measure body fat directly, but research has shown that BMI correlates to direct measures of body fat. It is screening tool and not a diagnostic tool (Barlow and Dietz, 1998).

With kids and teens, body fat changes with age and the amount of body fat differs between girls and boys. So BMI calculations are different for kids than adults. When your child’s BMI is calculated, the BMI number is plotted on a specific growth chart (for either girls or boys) to obtain a percentile ranking which will categorize the child as underweight, healthy, overweight or obese. (www.cdc.gov/)

So the question is, what do we do with this BMI report card that the school nurse sends home? If your child is categorized as overweight or obese, making the right decision will not be easy. But to determine if excess fat is a problem, a health care provider may need to perform further assessments.

These assessments might include skin fold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screens. Many parents may use this as a starting block for family fitness, better food choices and overall healthy lifestyle, which is always good practice whether your child has a weight problem or not.

Others may choose nothing as they may not really know what to do for their overweight child. Join a gym? See a doctor? Get a personal trainer? Most insurances do not cover weight management services in their medical plans despite the medical implications that obesity may cause.

Dr. Sandy Hassink, director of pediatric weight management clinic at AI DuPont Hospital for Children in Wilmington, suggests that if you are worried about your child’s weight, contact your pediatrician. Get a sense of what your child’s weight trends have been (is it a steady weight gain or sudden), what are they eating and what are their eating habits, and what kind of activity they do on a regular basis. (Pediatric Obesity, American Academy of Pediatrics 2007)

Lastly, weight management is a team effort. Singling out your child to lose weight without the support of the family will not be effective. Make a commitment for the entire family to make some positive, healthy changes such as healthier snacks and meals, less TV and more family activity. Dr. Hassink also suggests, “the changes that will help your child manage his/her weight today could also keep a serious illness from developing later.” And that is good food for thought.
