Ideal Weight Calculator
Four formulas, four answers. Science loves to keep you guessing.
Ideal Weight by Formula
Average Across Formulas
72.5 kg
Four different formulas, four different answers. The range they give you is more useful than any single number.
About This Calculator
How It Works
This calculator runs your height through four separate 'ideal weight' formulas — Devine, Robinson, Miller, and Hamwi — each developed independently by researchers in the 20th century. All four use height as the primary input, with a baseline weight for 5 feet and an increment added per inch above that. Because each was derived from different study populations, they produce slightly different results, which this calculator shows side-by-side rather than picking a winner.
The Formula
Devine: Men: 50 + 2.3×(height_in - 60). Robinson: Men: 52 + 1.9×(height_in - 60). Miller: Men: 56.2 + 1.41×(height_in - 60). Hamwi: Men: 48 + 2.72×(height_in - 60).
When to Use This
Ideal weight ranges are useful context when setting a goal weight or discussing targets with a doctor, but they're a starting point — not a prescription. If your current weight falls within or close to the range any of these formulas produces, that's broadly reassuring. If you're well outside all four, it's worth a conversation with a healthcare provider about what a realistic, healthy target looks like for your specific body.
Limitations
Every formula here was derived from actuarial or clinical data from specific (often limited) populations and doesn't account for muscle mass, bone density, body frame size, age, or ethnicity — all of which affect what a healthy weight actually looks like for a given individual. A muscular athlete will show as 'overweight' on all four formulas. Treat the output as a rough reference range, not a target you're obligated to hit.
Example
For a 5'10" (178cm) man: Devine = 75.5kg, Robinson = 77.1kg, Miller = 78.3kg, Hamwi = 77.2kg. They disagree by about 3kg. That's science keeping things interesting.
Did You Know?
The concept of 'ideal weight' has changed dramatically throughout history — what was considered healthy in the 1950s is quite different from today's understanding. Our bodies are diverse. Ranges beat single numbers.
