Frequently Asked Questions
What is an ideal weight?
Ideal-weight formulas provide estimated reference weights based primarily on height and sex. They are not a precise measurement of an individual's healthiest body weight.
Why are there different ideal weight formulas?
Different formulas use different constants and assumptions, so their estimates can vary. This calculator shows several methods rather than relying on a single estimate.
What is the healthy BMI weight range?
This calculator estimates the weight corresponding to a BMI between 18.5 and 24.9. BMI is a screening measure and does not directly measure body fat or body composition.
Which formula should I use?
These formulas provide reference estimates rather than personalized medical recommendations. Individual factors can make a healthy weight different from these estimates.
Important Information
This calculator provides general estimates for informational purposes only. Ideal-weight formulas do not account for factors such as muscle mass, body composition, age, medical conditions or individual health goals. It should not be used as a substitute for professional medical advice.
