Calcular Peso Ideal Por Idade E Altura

Determining your ideal weight based on age and height is an important step in maintaining a healthy lifestyle. This calculator provides a reliable estimate using established formulas and expert guidance.

How to Use This Calculator

To calculate your ideal weight:

Enter your height in centimeters
Select your age group from the dropdown
Click the "Calculate" button
Review your results and interpretation

The calculator will provide your ideal weight range based on your height and age. Remember that this is an estimate and individual factors may affect your actual weight.

Formula Used

The calculator uses the following formula to determine ideal weight:

Ideal Weight (kg) = (Height in cm - 100) ± 10%

This formula is based on the general principle that for every centimeter over 100cm, the ideal weight is approximately 1 kilogram, with a ±10% range accounting for individual variations.

For more precise calculations, the calculator adjusts the range based on age groups:

Children (0-12 years): ±15% range
Teens (13-19 years): ±12% range
Adults (20-65 years): ±10% range
Seniors (65+ years): ±15% range

Interpreting Results

The calculator provides a weight range rather than a single number because:

Body composition varies between individuals
Muscle mass differs from fat mass
Genetic factors influence weight distribution
Health conditions may affect weight

If your actual weight falls outside the calculated range, consider consulting with a healthcare professional to determine if it's healthy for you.

Worked Examples

Example 1: 170cm, Adult (25-65 years)

Calculation: (170 - 100) = 70kg ± 10% = 63kg to 77kg

Interpretation: A 170cm adult should aim for a weight between 63kg and 77kg.

Example 2: 160cm, Teen (15 years)

Calculation: (160 - 100) = 60kg ± 12% = 52.8kg to 67.2kg

Interpretation: A 160cm teenager should aim for a weight between 52.8kg and 67.2kg.

Example 3: 150cm, Child (8 years)

Calculation: (150 - 100) = 50kg ± 15% = 42.5kg to 57.5kg

Interpretation: A 150cm child should aim for a weight between 42.5kg and 57.5kg.

Frequently Asked Questions

Is the ideal weight formula accurate for everyone?: The formula provides a general estimate. Individual variations in body composition, muscle mass, and health conditions may affect actual weight.
Why does the calculator show a range instead of a single number?: The range accounts for natural variations in body composition and individual differences. It's important to focus on overall health rather than strict weight targets.
How often should I recalculate my ideal weight?: You should reassess your ideal weight when your height changes significantly or when you reach new age milestones (like becoming an adult).
What if my actual weight is outside the calculated range?: If you're significantly underweight or overweight, consult with a healthcare professional to determine if your weight is healthy for your specific situation.
Does this calculator account for gender differences?: The basic formula doesn't include gender-specific adjustments, but the ±10% range accounts for most individual variations.
