Healthy Weight Calculator
Enter a valid height.
This range is based purely on Body Mass Index (BMI), which doesn't account for muscle mass, frame size, or where fat is distributed — a very muscular person can have a "high" BMI while being lean. Use it as one general reference point, not a precise personal target.
Free healthy weight calculator that gives a BMI-based weight range for your height — a single input, a clear range, and an honest note about what BMI does and doesn't capture.
How it works
- Enter your height
- See the weight range corresponding to a BMI of 18.5-24.9
Frequently asked questions
Why a range instead of one number?
The standard BMI-based healthy weight band spans 18.5 to 24.9, which converts to a real weight range for any given height — a single 'ideal' number would falsely imply more precision than BMI actually provides.
What does this range miss?
BMI doesn't distinguish muscle from fat or account for frame size — a muscular athlete can land above this range while being lean and healthy. Use this as one general reference point alongside other measures, not a strict target.
