Frequently asked questions
Why do the formulas give different numbers?
Each was derived from different data and assumptions, so they vary by a few kilograms. Treating them as a range is more realistic than picking one exact number.
Is ideal body weight the same as a healthy weight?
Not exactly. These height-based formulas ignore muscle and frame size — a muscular person may be heavier yet perfectly healthy. Use it as a guide, not a target.
