Synopsis: Explains what body mass index measurement means, includes BMI calculator and chart for adults and instructions on how to measure your waist circumference.

Why it matters: A Body Mass Index (BMI) calculator is a valuable tool for assessing an individual's health status related to their weight and height. It provides a quick and easy way to determine if a person falls within a healthy weight range, is underweight, overweight, or obese. When combined with waist circumference measurements, BMI can help identify potential health risks associated with excess body fat, such as an increased risk for type 2 diabetes, cardiovascular disease, and hypertension. This information can be particularly useful for healthcare professionals and individuals alike in evaluating overall health, setting weight management goals, and monitoring progress over time. However, it's important to note that BMI is just one factor in assessing overall health and should be considered alongside other health indicators and individual circumstances - Disabled World (DW).

Introduction

The body mass index (BMI) is a number derived from a formula, used to compare and analyse the health effects of weight on people of all ages and heights. Use our instant online body mass index calculator to find your current BMI measurement and learn how to measure your waist circumference.

Main Item

Your body mass index measurement combined with your Waist Circumference measurement can be used to determine obesity and the increased risk for various diseases. A high waist circumference is often associated with an increased risk for type 2 diabetes, cardiovascular disease, dyslipidemia and hypertension when your BMI is calculated between 25 and 34.9.

NOTE: For children aged 1 to 20 use our Body Mass Index Calculator for Children to calculate a child's BMI.

How to Measure Waist Circumference

Waist Circumference measurement is handy for people whose BMI indicates they maybe normal or overweight. EG. an athlete with an increased muscle mass may have a BMI greater than 25 - making them overweight on the BMI scale, however a Waist Circumference measurement would indicate that they are in fact not overweight. Men with a waist circumference more than 102 cm (40 in) and women with a waist circumference more than 88 cm (35 in) are at increased risk of developing health problems - Male and Female Waist to Hip Ratio Calculator

Find your upper hip bone, the waist is usually measured at one inch above the naval, place a measuring tape around the abdomen, be sure the tape is horizontal, the tape measure should be firm but should not compress the skin. Changes in your waist circumference over time can indicate an increase or decrease in your abdominal fat, an increase in abdominal fat is associated with an greater risk of developing heart disease. Physical activity and good nutrition are key factors in a healthy lifestyle.

Less than 18.5 =	Underweight
18.5 - 24.9 =	Normal weight
25 - 29.9 =	Overweight
30 - 34.9 =	Class I obese
35 - 39.9 =	Class II obese
40 upwards =	Class III obese

Remember, BMI is only one piece of a person's health profile and just one of the many factors related to developing a serious disease. There are other factors that are important when assessing your risk for chronic disease including:

Blood Sugar Level
Cholesterol Level
Family History of diseases
Daily Diet
Waist Circumference
Blood Pressure
Physical Activity

Adult BMI Chart

To read the Adults BMI chart, or table, find your height in the left-hand column labeled Height. Then move across to your weight (in pounds). The number at the top of the column is the correct BMI measurement for that height and weight. To keep the page mobile friendly, the chart consists of 4 progressive tables - so if your numbers don't match the first table move down to the next one.

(Pounds have been rounded off)*. See further down the page for a printable BMI chart for adults.

English and Metric Formula for Calculating BMI

Imperial BMI Formula

Body Mass Index is calculated using pounds and inches with this equation:

BMI = (Weight in Pounds (Height in inches) x (Height in inches) ) x 703

For example, a person who weighs 220 pounds and is 6 feet 3 inches tall has a BMI of 27.5

(220 lbs. (75 inches) x (75 inches) ) x 703 = 27.5

Metric BMI Formula

BMI = Weight in Kilograms (Height in Meters) x (Height in Meters)

BMI = (Weight in Kilograms (Height in centimeters) x (Height in centimeters) ) x 10,000

For example, a person who weighs 99.79 Kilograms and is 1.905 Meters (190.50 centimeters) tall has a BMI of 27.5.

99.79 Kg (1.905 m) x (1.905 m) = 27.5
