Sizing it up. When airlines refer to âcarry-on luggageâ or âcarry-on baggage,â they mean the bag that meets size specifications to store it in the overhead bin. Trouble is, there is no such thing as a standard carry-on size. Every U.S. airline has its own rules. The big threeâAmerican, Delta, and United/U.S. Airwaysâhave settled on a uniform size (for now). Itâs 22 inches high x 9 inches deep x 14 inches wideâthese are external dimensions, including wheels and the handle. A few U.S. airlines are more generous with their carry-on size allowance, but some also impose weight restrictions and/or fees for carry-on baggage.
Calculate Your Body Mass Index. Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. 1  Enter your weight and height using standard or metric measures. 2  Select Compute BMI and your BMI will appear below.
Body Mass Index (BMI) can be calculated using a simple formula: Body weight in kilograms divided by the squared height in meters. Body Mass Index (BMI) does not take into account an above average amount of muscle mass in your body. By having many trained muscles, the ideal/normal weight of your body may be higher.
