Is There One Ideal Weight?
No single weight is universally ideal. Four commonly used medical formulas each produce slightly different estimates. Using the average gives a practical healthy range.
The 4 Ideal Weight Formulas
| Formula | Year | 5'10" Male | 5'6" Female |
|---|---|---|---|
| Devine | 1974 | 166 lbs | 130 lbs |
| Robinson | 1983 | 160 lbs | 127 lbs |
| Miller | 1983 | 157 lbs | 130 lbs |
| Hamwi | 1964 | 172 lbs | 135 lbs |
Healthy BMI Range
The CDC defines healthy BMI as 18.5–24.9. For a 5'10" male, this is 129–173 lbs. For a 5'6" female, it's 115–154 lbs. These are population-level screening ranges, not individual prescriptions.
Limitations
Ideal weight formulas don't account for muscle mass or bone density. An athlete may weigh 20 lbs above "ideal" with 10% body fat. Body fat percentage is a more meaningful metric for active individuals.
