Ideal Weight Calculator (Multiple Formulas)
Estimate your ideal weight range based on your height and gender using several established formulas. Compare multiple methods to find a reasonable target weight.

Your Ideal Weight Range
These calculations are estimates based on different formulas. Individual factors like body composition, age, and fitness level may suggest a different ideal weight for you.
Understanding Ideal Body Weight (IBW)
Ideal Body Weight (IBW) is a concept used historically, particularly in medicine, to estimate a healthy weight range based primarily on height and gender. It doesn't account for factors like muscle mass, body composition, or individual health status, so it should be viewed as a general guideline rather than a definitive measure of health.

Common IBW Formulas
Several formulas exist to estimate IBW. This calculator uses:
- Devine (1974): Male: 50kg + 2.3kg/inch over 5ft. Female: 45.5kg + 2.3kg/inch over 5ft.
- Robinson (1983): Male: 52kg + 1.9kg/inch over 5ft. Female: 49kg + 1.7kg/inch over 5ft.
- Miller (1983): Male: 56.2kg + 1.41kg/inch over 5ft. Female: 53.1kg + 1.36kg/inch over 5ft.
- Hamwi (1964): Male: 48kg + 2.7kg/inch over 5ft. Female: 45.5kg + 2.2kg/inch over 5ft.
These formulas often yield slightly different results, highlighting the estimation involved.
Limitations of IBW Formulas
IBW formulas were often developed based on specific populations and don't consider body composition (muscle vs. fat), frame size, age, or ethnicity. A muscular person might weigh more than their calculated IBW but still be very healthy. Conversely, someone within their IBW range could have unhealthy levels of body fat. (150-250 words)
Focusing on Healthy Weight
A truly "ideal" weight is one that supports your long-term health and well-being. Instead of fixating on a single number, consider factors like energy levels, physical fitness, balanced diet, waist circumference, and absence of weight-related health issues (like high blood pressure or type 2 diabetes). BMI and body fat percentage can offer additional insights. Always consult healthcare professionals for personalized assessments. (200-300 words)
Ideal Weight Calculator FAQs
Why do the different formulas give different results?
The formulas were developed by different researchers at different times, often based on slightly different populations or assumptions. This variation underscores that IBW is an estimate, not an exact science. (50-80 words)
Is ideal weight the same as a healthy BMI?
Not necessarily. While there's often overlap, IBW formulas are simpler and don't directly correlate with BMI ranges. Both are screening tools, but BMI is more widely used today for assessing weight categories relative to health risks. (50-80 words)
Does frame size affect ideal weight?
Some older methods adjusted IBW for frame size (small, medium, large), but measuring frame size is subjective. The formulas used here don't incorporate frame size, focusing solely on height and gender for simplicity. (50-80 words)
What if my weight is outside the calculated ideal range?
Don't panic. It's just a guideline. Focus on healthy habits like balanced eating and regular exercise. Consult your doctor to assess your individual health status and determine if your current weight is appropriate for you. (50-80 words)
Are these formulas suitable for children or adolescents?
No, these formulas are intended for adults (typically 18+). Assessing healthy weight in children and teens requires different methods, usually involving growth charts and BMI-for-age percentiles. Consult a pediatrician. (50-80 words)
