Ideal Weight Calculator: Healthy Weight Ranges
What Is Ideal Body Weight and Why Does It Matter?
Ideal Body Weight (IBW) is an estimate of the healthiest weight for a person based on height, gender, and sometimes age. Unlike BMI, which is a population-based screening tool, IBW is often used by healthcare professionals to guide medication dosing, assess health risks, and set realistic weight goals. Understanding your ideal weight can help you make informed decisions about your health, fitness, and nutrition.

Ideal Weight by Age Group & Special Populations
Young Adults (18-30)
Focus on establishing healthy habits. Ideal weight calculations are most accurate for this age group. Consider muscle mass from sports or fitness activities.
Older Adults (51+)
Muscle mass naturally decreases with age. Focus on strength training and maintaining a healthy weight range rather than exact numbers.
Middle Age (31-50)
Metabolism changes may affect weight management. Focus on maintaining healthy weight through balanced nutrition and regular exercise.
Athletes & Active Individuals
Higher muscle mass may make you weigh more than the "ideal" while being perfectly healthy. Focus on body composition and performance metrics.
FAQs About the Ideal Weight Calculator
Is ideal weight the same as healthy weight?
No, ideal weight is a guideline. Healthy weight also depends on age, body composition, and other factors. Always consult a healthcare provider for personalized advice.
How often should I check my ideal weight?
Check when your height changes or as part of annual health reviews. Use it as a reference, not a daily metric.
Is the Devine formula accurate?
