Ideal Weight Calculator
Estimate a healthy target weight for your height using four established medical formulas.
Average ideal weight
159.4 lbs (72.3 kg)
Healthy weight range (BMI 18.5-24.9)
128.9-173.5 lbs
What Your Result Means
There's no single "correct" ideal weight formula - each was developed by different researchers using different populations. Showing all four alongside their average gives you a realistic range rather than a single number that might not fit your build.
How It Is Calculated
Devine (men): 50 kg + 2.3 kg per inch over 5 ft
Robinson, Miller, and Hamwi use similar height-based formulas with different constants.
Worked Example
A man who is 5'10" tall has an average ideal weight of roughly 72-75 kg (159-165 lbs) across the four formulas.
Important Assumptions
- These formulas were originally developed for medication dosing, not aesthetics - they estimate a healthy population-average weight for a given height.
- They don't account for muscle mass, frame size, or body composition.
- The healthy BMI range (18.5-24.9) is shown as an additional reference point.
Frequently Asked Questions
- Which formula is most accurate?
- None is definitively "most accurate" - they were developed decades apart for different purposes. The average of all four, shown here, gives a reasonable general estimate.
- Should athletes use this calculator?
- Not really. Athletes with significant muscle mass will often weigh more than these formulas suggest while still being at a healthy body fat percentage. Consider using the Body Fat Calculator alongside this one.
