How it works
Each formula starts from a base weight for a height of five feet, then adds a set amount for every inch above that. The base and the amount depend on sex. Heights under five feet are counted as five feet here.
Devine, Robinson and Miller each use their own published numbers, so they give slightly different answers. Compare the three rather than relying on one.
Worked example
At 68 in tall, the Devine formula gives 150.8 lb, Robinson gives 148.2 lb and Miller gives 148.8 lb. These are formula outputs, not a goal.
Questions
Is this my target weight?
No. These are reference figures from formulas. They do not account for muscle, frame or health.
Why are the three answers different?
Each formula was published with different data, so the numbers can differ by a few kilograms or pounds.
Who uses these figures?
Mostly clinicians and researchers, in calculations. Your doctor can tell you what weight suits you.
