Ideal Weight Calculator – What Is a Healthy Weight for Your Height?

This Ideal Weight Calculator helps you estimate a healthy body weight range based on your height and gender using three widely recognized formulas:Devine, Robinson, and Hamwi. Rather than relying on a single number, these formulas provide a realistic reference range that reflects long-standing medical and fitness standards.

Health guidance aligned with the World Health Organization (WHO) emphasizes maintaining a healthy body weight to reduce the risk of chronic conditions such as cardiovascular disease, diabetes, and metabolic disorders. This calculator translates those principles into practical, easy-to-understand estimates.

What Does “Ideal Weight” Mean?

Ideal body weight refers to an estimated weight range considered healthy for a given height and gender. It is not meant to represent a perfect or mandatory number, but rather a reference point associated with lower health risks and better overall physical functioning.

Unlike scale weight alone, ideal weight calculations are designed to account for average body frame, skeletal structure, and natural differences between men and women. They are commonly used in healthcare, nutrition planning, and fitness goal-setting.

Why Knowing Your Ideal Weight Is Useful

Understanding your ideal weight range helps you set realistic expectations and avoid unhealthy extremes. It provides context for interpreting other health metrics such as BMI, body fat percentage, and waist circumference.

• Supports realistic weight-loss or weight-gain goals
• Helps evaluate whether current weight is within a healthy range
• Provides reference points for nutrition and fitness planning
• Commonly used in medical and clinical assessments

Ideal Weight Formulas Used in This Calculator

This calculator uses three established formulas, each developed for slightly different purposes but widely accepted in health and medical contexts.

• Devine Formula:Originally developed for medical dosing calculations. It is one of the most commonly cited ideal weight formulas in clinical settings.
• Robinson Formula:A refinement of earlier formulas that produces slightly higher estimates and reflects modern population averages.
• Hamwi Formula:A traditional method that provides a broader ideal weight estimate and is still referenced in nutrition and fitness planning.

By showing all three results and an average, this calculator avoids relying on a single assumption and instead provides a balanced reference range.

How This Ideal Weight Calculator Works

The calculator converts your height from centimeters to inches, then applies each formula using standardized coefficients. All results are expressed in kilograms and averaged to produce a recommended ideal weight estimate.

All calculations happen instantly in your browser. No personal information is stored, tracked, or transmitted.

Ideal Weight Calculation Example

Consider a male individual with a height of 170 cm.

This suggests that a weight around 66 kg would fall within a commonly accepted healthy range for this height, assuming average body composition.

Ideal Weight vs BMI: What’s the Difference?

BMI categorizes weight relative to height but does not distinguish between fat and muscle. Ideal weight formulas, on the other hand, provide a more direct estimate of a target weight range based on height and gender.

For athletes or individuals with higher muscle mass, BMI may label them as overweight even when body fat is low. Ideal weight calculations can offer additional context in such cases.

Who Should Use This Ideal Weight Calculator?

This calculator is intended for adults seeking a general reference for healthy body weight.

• People planning weight-loss or weight-gain goals
• Individuals starting a fitness or wellness journey
• Those comparing BMI results with other metrics
• People interested in long-term health planning
• Anyone wanting a medically grounded weight reference

Benefits of Using an Ideal Weight Calculator

• Provides realistic weight targets
• Reduces reliance on scale weight alone
• Supports balanced fitness and nutrition goals
• Useful alongside BMI, body fat, and metabolic tools
• Encourages sustainable, health-focused progress

Limitations of Ideal Weight Formulas

Ideal weight formulas are estimates, not diagnoses. They do not account for individual differences such as muscle mass, bone density, genetics, or body fat distribution.

Accuracy may vary for:

• Athletes or bodybuilders
• Older adults with muscle loss
• People with unusually large or small body frames
• Medical conditions affecting weight or metabolism

For personalized medical guidance, consult a qualified healthcare professional.

How to Use This Calculator Effectively

Use your ideal weight result as a reference point, not a strict target. Combine it with other metrics such as body fat percentage, waist measurement, energy levels, and overall well-being. Tracking trends over time is far more valuable than focusing on a single number.
