Como Calcular Peso Ideal Segun Estatura Y Edad

Reviewed by Calculator Editorial Team

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 can help you estimate your target weight range. This guide explains how to calculate ideal weight using different approaches and what factors to consider.

How to calculate ideal weight

There are several formulas to estimate ideal weight based on height. The most common methods include:

Broca's Index

This formula subtracts 100 cm from your height in centimeters and then multiplies by 0.9:

Ideal Weight (kg) = (Height (cm) - 100) × 0.9

For example, a person who is 170 cm tall would calculate:

(170 - 100) × 0.9 = 63 kg

Lorentz Formula

This formula subtracts 100 cm from your height and then multiplies by 0.85:

Ideal Weight (kg) = (Height (cm) - 100) × 0.85

Using the same example of 170 cm tall:

(170 - 100) × 0.85 = 59.5 kg

Miller's Formula

This formula subtracts 152.4 cm from your height and then multiplies by 0.75:

Ideal Weight (kg) = (Height (cm) - 152.4) × 0.75

For a 170 cm tall person:

(170 - 152.4) × 0.75 = 13.2 kg

BMI-based Calculation

The Body Mass Index (BMI) is another way to estimate weight. The healthy BMI range is typically 18.5 to 24.9. You can calculate your ideal weight range using:

Ideal Weight Range (kg) = BMI × (Height (m))²

For example, a 170 cm (1.7 m) tall person:

Lower bound: 18.5 × (1.7)² = 54.6 kg

Upper bound: 24.9 × (1.7)² = 69.7 kg

Formula used in the calculator

The calculator uses the following formula based on your selected method:

Broca's Index: (Height (cm) - 100) × 0.9

Lorentz Formula: (Height (cm) - 100) × 0.85

Miller's Formula: (Height (cm) - 152.4) × 0.75

BMI-based: BMI × (Height (m))²

All calculations are performed in metric units. For imperial units, convert your height to centimeters first.

Other factors affecting weight

While height is the primary factor in estimating ideal weight, several other factors influence your weight:

  • Body composition: Muscle mass and fat percentage affect weight more than height alone
  • Age: Weight tends to decrease with age due to muscle loss and reduced activity levels
  • Gender: Women typically have lower ideal weights than men of the same height
  • Muscle mass: Athletes and bodybuilders may weigh more than the average person of their height
  • Bone density: People with higher bone density may weigh more than others

These factors mean the ideal weight range is more of a guideline than an exact target.

Frequently Asked Questions

Is the ideal weight the same for everyone?
No, ideal weight varies based on height, age, gender, and body composition. The formulas provide estimates, but individual differences exist.
Why do different formulas give different results?
Different formulas were developed at different times with different populations in mind. They provide ranges rather than exact targets.
Should I aim for the exact number from the calculator?
No, the calculator provides a range. Focus on maintaining a healthy weight within the recommended BMI range rather than targeting an exact number.
How does age affect ideal weight?
Weight typically decreases with age due to muscle loss and reduced activity levels. The calculator doesn't account for age beyond height.
