Como Calcular Mi Peso Ideal Segun Mi Altura Y Edad

Determining your ideal weight based on height and age is an important step in maintaining a healthy lifestyle. While there's no single perfect formula, several reliable methods exist that consider both biological factors and individual differences. This guide explains the most common approaches and helps you calculate your ideal weight using our calculator.

How to calculate ideal weight

The concept of "ideal weight" is based on statistical averages of healthy individuals with similar height and age. Here's how to approach the calculation:

Step 1: Measure your height accurately

Use a stadiometer or measuring tape to determine your height in centimeters. Stand straight with your back against the wall and feet flat on the floor. Measure from the top of your head to the bottom of your feet.

Step 2: Consider your age group

Different age groups have different average body weights for the same height. Common categories include:

Children and adolescents
Adults (18-65 years)
Seniors (65+ years)

Step 3: Choose a calculation method

Several formulas exist, but the most commonly used are the Hamwi formula for adults and the Robinson formula for children. We'll explain both in detail below.

Step 4: Apply the formula

Use our calculator to input your height and age, then select the appropriate method. The calculator will provide your ideal weight range based on the selected formula.

Step 5: Interpret the results

Compare your actual weight with the calculated range. If you're significantly outside this range, consider consulting with a healthcare professional to understand the causes and appropriate next steps.

Formula used

The calculator uses two primary formulas:

Hamwi Formula (Adults)

For males: Ideal weight = (Height in cm - 100) × 0.9 × 1.1

For females: Ideal weight = (Height in cm - 100) × 0.9 × 0.9

Robinson Formula (Children)

For boys: Ideal weight = (Height in cm - 80) × 2.3

For girls: Ideal weight = (Height in cm - 80) × 2.3

These formulas are based on statistical averages of healthy individuals. They provide a general guideline rather than an exact measurement of ideal body weight.

Note: These formulas are most accurate for individuals with average body composition. Athletes, muscular individuals, or those with significant muscle mass may have different ideal weight ranges.

Different calculation methods

Several methods exist for calculating ideal weight, each with its own assumptions and applications:

Method	Formula	Best for
Hamwi	(Height - 100) × 0.9 × (1.1 for males, 0.9 for females)	Adults (18-65 years)
Robinson	(Height - 80) × 2.3	Children and adolescents
Devine	(Height in inches - 60) × 2.3	Adults (18-65 years)
Lorenz	(Height in cm - 100) × 0.9	General population

Choose the method that best fits your age group and body type. The Hamwi and Robinson formulas are particularly common in medical and fitness contexts.

Worked example

Let's calculate the ideal weight for a 170 cm tall adult male using the Hamwi formula:

Height = 170 cm

Gender = Male

Formula: (Height - 100) × 0.9 × 1.1

Calculation: (170 - 100) × 0.9 × 1.1 = 70 × 0.99 = 69.3 kg

Result: Your ideal weight range is approximately 69.3 kg

This means a 170 cm tall adult male should aim to maintain a weight around 69.3 kg for optimal health. Individual variations may exist based on muscle mass, body fat percentage, and other factors.

Frequently asked questions

Is the ideal weight the same for everyone?: No, ideal weight varies by age, gender, and body composition. The formulas provide general guidelines based on statistical averages.
Can I use these formulas for athletes?: These formulas are designed for average individuals. Athletes with significant muscle mass may need different calculations that account for body composition.
What if I'm significantly outside the ideal weight range?: Consult with a healthcare professional to determine if your weight is due to muscle mass, fat distribution, or other health factors.
Are these formulas scientifically proven?: These formulas are based on statistical data from healthy populations. They provide useful guidelines but shouldn't be considered absolute measurements.
How often should I recalculate my ideal weight?: As you age or change your activity level, you may need to reassess your ideal weight range. Generally, annual checks are sufficient for most people.
