Q:
# How is ideal weight determined?

**There are several ways to determine ideal body weight, including charts that compare height to weight, weight calculators that factor in body frame, and weight body mass index calculators.** There are several resources online that calculate ideal weight by entering personal information to determine it.

To calculate body mass index, multiply the weight in pounds by .45. Multiply the height in inches by .025 and square the result. Divide the first answer that factors in weight by the second answer that factors in height. The result is a person's body mass index.

A healthy body mass index, or BMI, ranges between 19 and 25. It is considered underweight to have a body mass index of 18.5 or lower and overweight to have a body mass index of 25 to 29.9. A body mass index of 30 or higher is categorized as obese.

Body mass index may underestimate body fat for people with low muscle mass or who are older. It may also overestimate body fat for physically fit and muscular people. Body weight is simply a tool to indicate health. While charts and calculators can give a sense of ideal body weights, it is also important to factor in body fat percentage.
