Ideal Weight Calculator
Healthy weight range for your height
How Ideal Weight Is Determined
There is no single "ideal weight" for any given height. This calculator uses multiple scientifically-developed formulas to provide a range. Each formula was developed through different research studies and may give slightly different results. The average of these formulas provides a reasonable target range.
Formulas Used
The Devine formula (1974) is the most widely used in clinical settings for drug dosage calculations. The Hamwi formula (1964) is commonly used by dietitians. The Robinson formula (1983) is based on Metropolitan Life Insurance actuarial data. The BMI-based range uses the healthy BMI window of 18.5 to 24.9 to calculate the weight range for your height.
Factors Beyond Height and Gender
Ideal weight depends on many factors beyond height and gender, including body composition (muscle vs fat), bone density, age, fitness level, and overall health. Athletes and people with high muscle mass may weigh more than these estimates while being perfectly healthy. These formulas provide general guidelines, not absolute targets.
A Healthy Approach to Weight
Rather than fixating on a specific number, focus on maintaining a healthy lifestyle with balanced nutrition, regular physical activity, adequate sleep, and stress management. Your healthcare provider can help determine what weight range is healthiest for your individual circumstances, considering your medical history and overall health profile.
How to use this result wisely
Health numbers are useful when they help you notice patterns, not when they create pressure. Treat this result as a starting point and compare it with your age, lifestyle, activity level, sleep, medical history, and personal goal. If the output looks surprising, recheck the units and inputs first. A single calculator cannot understand your full body, but it can help you ask better questions and track progress more clearly.
Quick example
For example, after using the Ideal Weight tool, note the result and the inputs you used. If you repeat the check later, use the same units and similar conditions so the comparison is fair.
Before you rely on the answer
- Check that every input is in the correct unit.
- Try one alternate scenario if the decision is important.
- Use the result as guidance, not as the only source of truth.
Important health note
This calculator is for general information and self-checking only. It should not be used as a diagnosis, treatment plan, or replacement for advice from a qualified doctor, dietitian, trainer, or other healthcare professional. If you are pregnant, managing a medical condition, taking medication, recovering from illness, or making a major diet or exercise change, please speak with a professional before acting on the result.
Common ways people use this calculator
This tool is useful for setting a baseline, planning a fitness goal, comparing progress, or understanding a health-related number in plain language. It works best when the input values are honest and consistent. For example, use the same measurement method each time and avoid comparing results taken under very different conditions.
Accuracy tips
Health estimates can vary from person to person. Age, body composition, sleep, stress, medication, training history, pregnancy, and medical conditions can all affect what a result means in real life. Use the number as a guide for awareness and planning, then adjust based on professional advice and how your body actually responds.
Ideal Weight Calculator: practical guide
The Ideal Weight Calculator is built for people who want a fast answer without losing context. It keeps the calculation simple, shows the result clearly, and helps you understand what the number means before you use it in a real decision.
Conversion tools help translate values between measurement systems quickly. They are especially useful when comparing products, recipes, travel details, technical values, or international information.
How this calculator supports better decisions
A good calculator should do more than display a number. It should help you check assumptions, compare scenarios, and avoid mistakes caused by wrong units or incomplete information. Before relying on the output, review every field and make sure the values match your actual situation.
Example use case
If you are ordering materials or following a recipe from another country, convert the value first and then round only at the final step.
Limitations to keep in mind
Use the result as a practical health estimate, not as a medical diagnosis. Recheck your measurements, consider your age and lifestyle, and speak with a qualified professional before making major diet, training, pregnancy, or treatment decisions.
