Ideal Weight Calculator

An ideal weight calculator is an online tool that estimates your ideal body weight (IBW) based on your height, gender, and frame size using scientifically established formulas. Whether you're setting weight loss goals, assessing health risks, planning fitness programs, or consulting with healthcare providers, our calculator provides IBW estimates using multiple validated formulas including Robinson, Miller, Devine, and Hamwi methods.

This calculator determines ideal weight ranges rather than single numbers, recognizing that healthy weight varies based on frame size, muscle mass, and individual factors. It provides estimates from multiple formulas, shows healthy BMI range for your height, and helps you understand realistic weight goals. The results serve as general guidelines; individual health needs may vary.

Understanding ideal weight helps set realistic health goals and assess weight-related health risks. Many people set weight loss goals based on unrealistic expectations, fad diets, or outdated standards. Ideal weight formulas provide scientifically-based estimates accounting for height and gender, helping you set achievable goals within healthy ranges rather than pursuing unhealthy extremes.

Healthcare professionals use IBW calculations for medication dosing, nutritional planning, and health risk assessment. Fitness trainers benefit from helping clients set realistic weight goals that account for individual body structure. Individuals planning weight loss or gain use IBW as a starting point for goal-setting, understanding that muscle mass, frame size, and body composition also matter.

The tool ensures accuracy by using multiple established formulas, provides weight ranges rather than absolutes, and helps contextualize goals with BMI information. It's particularly valuable when setting initial weight goals, evaluating weight loss progress, understanding healthy weight for your height, or discussing weight management with healthcare providers.

Weight Loss Goals: Set realistic target weights based on scientific formulas rather than arbitrary numbers or unhealthy societal pressures.

Fitness Planning: Establish healthy weight ranges when beginning fitness programs, bodybuilding, or athletic training.

Health Assessment: Understand if current weight falls within ideal ranges or if weight management is needed for health reasons.

Medical Consultations: Discuss weight-related health topics with doctors using scientifically-based ideal weight estimates.

Nutritional Planning: Create meal plans and calorie targets aimed at reaching and maintaining ideal body weight for health.

Using our ideal weight calculator is straightforward: enter your height (in feet/inches or centimeters) and gender. The calculator shows ideal weight estimates from multiple formulas plus your healthy weight range based on normal BMI (18.5-24.9). Compare results across formulas to understand your ideal weight range rather than focusing on one specific number.

Common formulas: Robinson (1983) for men: 52 kg + 1.9 kg per inch over 5 feet, for women: 49 kg + 1.7 kg per inch over 5 feet. Devine (1974) for men: 50 kg + 2.3 kg per inch over 5 feet, for women: 45.5 kg + 2.3 kg per inch over 5 feet. Miller (1983) and Hamwi (1964) use similar approaches with slight variations. For example, a 5'8" man has IBW estimates ranging from 154-172 lbs across formulas. Healthy BMI range provides broader guidance: 121-164 lbs for this height.
