Ideal Weight Calculator: What Should I Actually Weigh?

"What should I weigh?" is one of the most Googled health questions. The honest answer: it depends on your height, body composition, age, and genetics. No single number is right for everyone. But formulas can give you a reasonable range.

Calculate Your Range

The Ideal Weight Calculator uses four different scientific formulas (Devine, Robinson, Miller, Hamwi) and shows you the range. Using multiple formulas gives you a realistic window rather than a single misleading number.

For a 5'10" Male

• Devine formula: 166 lbs
• Robinson formula: 165 lbs
• Miller formula: 163 lbs
• Hamwi formula: 166 lbs
• BMI range (18.5-24.9): 129-174 lbs

So somewhere around 155-175 lbs is the general target. But a muscular person at 185 could be perfectly healthy, while someone at 165 with very little muscle might not be.

Why These Numbers Are Limited

All ideal weight formulas were created decades ago using specific populations. They don't account for muscle mass, bone density, or body composition. An athlete at 200 lbs with 12% body fat is healthier than a sedentary person at 165 lbs with 30% body fat, even though the formulas say the second person is closer to "ideal."

Use these numbers as a general guide, not a prescription. How you feel, how you perform, and what your doctor says about your blood work matter more than hitting a number on a chart.
