Health
A height-based reference weight from the Devine formula. It was developed for medication dosing — it is not a personal health or appearance target.

Bars are scaled to the larger value. The 4.5 kg base difference is the only gap between the bars at any height.
Above 5 feet (60 inches), add 2.3 kg per inch to a base of 50 kg for men or 45.5 kg for women. At or below 5 feet the formula gives the base value. Height in inches = height (cm) ÷ 2.54.
Height 170 cm, female: 170 ÷ 2.54 = 66.93 inches, which is 6.93 inches above 5 feet. Reference weight = 45.5 + 2.3 × 6.93 = 45.5 + 15.94 = 61.4 kg (135.4 lb). The male base at the same height gives 65.9 kg, and the BMI at 61.4 kg and 170 cm is 21.3. Use Reset example above to reproduce this result.
The Devine formula uses height alone: it ignores build, muscle mass, age, and every other personal factor, and it was developed as a dosing reference rather than a health target. Calling the result “ideal” is the formula’s historical label, not a claim that this weight is best for any individual. Heights at or below 5 feet return the base value, since the formula adds nothing below that height.
No. It is a height-based reference number from a dosing formula. What weight suits an individual depends on factors this page does not model.
The formula uses different bases — 50 kg for men, 45.5 kg for women — with the same 2.3 kg per inch above 5 feet.
The formula adds nothing below 5 feet, so it returns the base value (50 kg or 45.5 kg). That flat result is a limit of the formula, not a meaningful target.
The table shows the BMI at the reference weight for your height, so you can see where the reference number sits in the standard BMI ranges.
No. This calculation runs locally in your browser and the values you enter are not sent to a CalcMintly database.
Treat it as a reference point for discussion, not a goal. Any weight goal should account for personal circumstances the formula cannot see.
