Calcular Peso Ideal Para Altura

Determining your ideal weight based on height is an important step in maintaining a healthy lifestyle. This calculator provides accurate results using the most reliable formulas, helping you understand your healthy weight range.

How to calculate ideal weight for height

Calculating your ideal weight involves using specific formulas that relate height to weight. The most common methods are the Hamwi formula, the Devine formula, and the Robinson formula. Each provides slightly different results based on gender and height.

Note: These formulas provide estimates only. Individual body composition varies, and these calculations don't account for muscle mass, bone density, or overall health.

Steps to calculate

Measure your height in centimeters
Select your gender
Choose the calculation method
Enter your height in the calculator
Click "Calculate" to get your ideal weight range

Example calculation

For a 170 cm tall male using the Hamwi formula:

Ideal weight = 48.0 + 2.7 × (height in inches - 60)

First convert 170 cm to inches: 170 ÷ 2.54 ≈ 66.93 inches

Then calculate: 48.0 + 2.7 × (66.93 - 60) ≈ 48.0 + 2.7 × 6.93 ≈ 48.0 + 18.71 ≈ 66.71 kg

This suggests a healthy weight range of approximately 66.7 kg.

Formula used

The calculator uses three main formulas for different purposes:

Hamwi Formula

Male: 48.0 + 2.7 × (height in inches - 60)
Female: 45.5 + 2.2 × (height in inches - 60)

Devine Formula

Male: 50.0 + 2.3 × (height in inches - 60)
Female: 45.5 + 2.3 × (height in inches - 60)

Robinson Formula

Male: 52.0 + 1.9 × (height in inches - 60)
Female: 49.0 + 1.7 × (height in inches - 60)

All formulas use height in inches. For metric users, the calculator automatically converts centimeters to inches before calculation.

Different calculation methods

Each formula provides slightly different results due to their different origins and intended populations:

Formula	Developed for	Typical Use
Hamwi	Japanese population	General population health
Devine	US population	Average weight estimation
Robinson	European population	Lean body mass estimation

For most practical purposes, all three formulas provide reasonable estimates. The Devine formula is often considered the most balanced for general use.

Interpreting your results

Your ideal weight range is an estimate, not an exact target. Here's how to interpret the results:

Underweight

If your actual weight is significantly below the calculated range, you may need to focus on gaining healthy weight through proper nutrition and exercise.

Healthy weight

If your weight falls within the calculated range, you're likely at a healthy body weight for your height.

Overweight

If your weight is above the calculated range, you may want to consult with a healthcare professional about maintaining a healthy weight.

Important: These calculations don't account for muscle mass, bone density, or overall health. BMI (Body Mass Index) is another common measure that considers both height and weight.

FAQ

Which formula should I use?

The Devine formula is generally recommended as it provides a balanced estimate for most populations. However, you can use any of the formulas to see how they compare.

Are these calculations accurate for everyone?

No, these formulas provide estimates. Individual body composition varies, and these calculations don't account for muscle mass, bone density, or overall health. For precise health assessments, consult with a healthcare professional.

How often should I recalculate my ideal weight?

You can recalculate your ideal weight whenever your height changes significantly or if you want to track changes in your body composition over time.

Can I use these calculations for children?

These formulas are designed for adults. For children, specialized growth charts and pediatric health guidelines should be used.
