Frequently Asked Questions

A BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is considered obese.

BMI can be misleading for muscular individuals since muscle weighs more than fat. Consider using body fat percentage or waist-to-height ratio for a more complete picture.

BMI equals your weight in kilograms divided by your height in meters squared. For imperial units, multiply weight in pounds by 703, then divide by height in inches squared.
