Calcular El.peso Ideal

Determining your ideal body weight is an important step in maintaining good health. This calculator helps you estimate your healthy weight range based on your height and gender using the most widely accepted formulas.

How to calculate your ideal weight

Calculating your ideal weight involves several steps:

Measure your height accurately in centimeters or inches
Select the appropriate formula based on your gender
Input your height into the calculator
Review the results and compare with your current weight

The results provide a healthy weight range rather than an exact target. Individual variations in body composition, muscle mass, and bone density can affect these calculations.

Common formulas for ideal weight

Several formulas are used to estimate ideal body weight:

Broca's Formula

For men: Ideal weight = (Height in cm - 100) × 1.1

For women: Ideal weight = (Height in cm - 100) × 1.08

This formula is based on average body proportions and is simple to calculate.

Lorenz Formula

Ideal weight = (Height in cm - 100) - (Height in cm - 150)/4

This formula provides a slightly different estimate than Broca's formula.

Robinson Formula

For men: Ideal weight = 52 + 1.9 × (Height in inches - 60)

For women: Ideal weight = 49 + 1.7 × (Height in inches - 60)

This formula is based on average body proportions and is commonly used in the United States.

The calculator uses Broca's formula by default, but you can select other formulas for comparison.

Interpreting your results

When you calculate your ideal weight range, consider these factors:

Your current weight compared to the healthy range
Your body composition (muscle mass vs. fat)
Your activity level and metabolism
Any medical conditions that might affect weight

A healthy weight range is generally considered to be between 18.5 and 24.9 on the BMI scale, but individual needs may vary.

Worked examples

Example 1: 170 cm male

Using Broca's formula:

(170 - 100) × 1.1 = 70 × 1.1 = 77 kg

Healthy weight range: 69.3 kg - 84.7 kg (based on BMI)

Example 2: 65 inches female

Using Robinson formula:

49 + 1.7 × (65 - 60) = 49 + 8.5 = 57.5 lbs

Healthy weight range: 125 lbs - 154 lbs (based on BMI)

Frequently asked questions

Which formula is most accurate?

No formula is perfectly accurate as individual variations exist. The formulas provide general guidelines based on average body proportions.

Should I aim for the exact ideal weight?

No, the ideal weight range is more important than an exact number. Focus on maintaining a healthy weight through balanced nutrition and regular exercise.

How often should I recalculate my ideal weight?

Recalculate when you have significant changes in height, growth spurts, or if you notice your body composition changing.

Are these formulas the same worldwide?

No, some formulas are more commonly used in certain regions. The calculator provides options for different formulas.
