The answer to the question “How much should I weigh?” is relative for everyone. Generally speaking, the goal is to maintain a normal weight; however, the exact value of normal weight could be different for each individual. A number of factors could help determine whether weight is normal for a certain person, foremost of which being the correlation between one’s weight and height.

For instance, under the Standard BMI Calculator that measures body fat by dividing height by weight, an adult who stands 6 ft. tall and weighs about 90 lbs. would have a BMI score of 24.4, which falls under the normal weight category. However, someone who weighs the same but only stands 5’6 ft. tall would already be considered overweight, and further, someone 5’4 ft. tall would already be in obese territory!

Meanwhile, another factor that could be taken in consideration when aiming for a certain weight is gender. While the Standard BMI Calculator is still considered appropriate for men, the same cannot be said for women. A BMI Calculator for women is used if one should interpret BMI scores based on women’s ideal range of values for a normal weight, which has been found to be slightly lower than that of men’s.

Also, one important note to be made about these types of BMI calculator is that they are not too adequate in terms of measuring actual body fat composition. In fact, someone whose weight is heavily impacted by a muscular build could be mistaken for someone fat, when the truth couldn’t be any further from it. Hence, one could also use a type of BMI Calculator, called body fat calculator, which factors in waist line. The formula runs under the assumption that a more toned body resulting from lesser fat composition would have a smaller waistline, and thus should have a lower BMI value.

Different variations of the BMI calculator are now widely available online, with some just having the standard height/weight statistics, while others having more, just like the above-mentioned gender and waist size. Some use the English BMI system, with Pounds and Inches as its units, while others use the Metric BMI system using Kilograms and Meters. Weight conversion tools are also widely available over the web to help anyone derive the proper set of values depending on the units of measure used by the BMI calculator. Nonetheless, anyone from any part of the world could simply rely on a weight converter to enter his proper height and weight values and generate a correct BMI score.

In conclusion, one important thing to remember is that these indicators are just approximations based on a given set of numbers. Since ideal weight is such a subjective term, one would still need some qualitative comparisons, such as lifestyle, to back these figures and find out exactly for oneself how much should one’s weight be.
