What Ideal Weight Is
Ideal weight is a healthy weight range for your height, gender, and frame size. There's no single "perfect" number—it's a range. This calculator uses several formulas (Hamwi, Devine, Robinson, Miller) that were developed for clinical use. They all give slightly different numbers, so you get a range to work with.
Your ideal weight depends on height (taller = higher range), gender (men typically weigh more for the same height), and frame size (bigger frame = more weight). Focus on where you feel strong and healthy, not just hitting a number.
Frequently Asked Questions
What's the difference between ideal weight and BMI?
BMI just uses height and weight. Ideal weight formulas factor in gender and frame size too. More personalized than BMI alone.
How do I determine my frame size?
Measure your wrist. For men: under 6.5" = small frame, 6.5-7.5" = medium, over 7.5" = large. For women: under 5.5" = small, 5.5-6.5" = medium, over 6.5" = large.
Why do different formulas give different results?
Each formula was made for different purposes. Hamwi = clinical use, Devine = medication dosing, Miller = more recent (tends lower). Using multiple gives you a better range.
Should I aim for the lowest weight in my range?
Not necessarily. Aim for where you feel strong, energetic, and can maintain healthy habits long-term. Body composition and activity level matter more than hitting a specific number.
How often should I recalculate?
Only if your height changes significantly or you're transitioning life stages (adolescence to adulthood). Otherwise it stays pretty stable.
