How it works

Estimates ideal body weight using the Devine formula based on height and sex.

Who it's for: Clinical staff, pharmacists cross-checking dosing weight, and adults looking for a height-based weight benchmark.

Devine formula: males 110 lb + 5 lb per inch over 5 feet; females 100 lb + 5 lb per inch over 5 feet.

Also displays the result in kilograms for medical records.

Provides a population average — not a personalized body-composition target.

How to use

  1. Select Sex.
  2. Enter Height in inches (e.g., 69 for 5 ft 9 in).
  3. Read Ideal weight in pounds.
  4. Optionally note In kilograms for charting.
  5. Compare to your current weight and BMI for a fuller picture.
  6. Use IBW dosing calculator if you need weight for medication calculations in obesity.

Good to know

  • Devine IBW can feel low for muscular builds — it was designed for drug dosing, not aesthetics.
  • Frame size and ethnicity are not adjusted in this formula.
