IW Calculator - Ideal Weight Calculator

The ideal weight calculator is a tool to hep you know how much you should weigh. It will help you determine your ideal body weight based on your height and gender. We will help you to learn the different formulas for calculating your IBW (ideal body weight) and how to interpret the results. You will also learn about how to use the healthy weight chart, which is based on BMI.

How much should I weight?

There are many ways to estimate somebodies ideal weight. Truth be told, none of them is perfectly accurate, as there are a lot of factors influencing it. For example, for people with a lot of muscle mass (and high lean body mass), their ideal weight will tend to be more than indicated by the results they obtain.

Our ideal body weight calculator uses four different formulas to find your ideal weight, as well as giving you your BMI . While the four formulas listed below give you only one number that you should be aiming for, BMI gives you a certain weight range you should be in.

For men, the ideal weight calculator uses the following equations:

  • Robinson formula: 52 kg + 1.9 kg per every inch over 5 feet
  • Miller formula: 56.2 kg + 1.41 kg per every inch over 5 feet
  • Hamwi formula: 48.0 kg + 2.7 kg per every inch over 5 feet
  • Devine formula: 50.0 kg + 2.3 kg per every inch over 5 feet

For women, the ideal weight calculator uses the following equations:

  • Robinson formula: 49 kg + 1.7 kg per every inch over 5 feet
  • Miller formula: 53.1 kg + 1.36 kg per every inch over 5 feet
  • Hamwi formula: 45.5 kg + 2.2 kg per every inch over 5 feet
  • Devine formula: 45.5 kg + 2.3 kg per every inch over 5 feet

Height weight chart and BMI

The last indicator of an individuals ideal weight is BMI, short for Body Mass Index. It is calculated according to BMI = weight/height². The optimal, healthy range for BMI is between 18.5 and 24.9. Our ideal weight calculator converts this back into weight, presenting to you the range of appropriate weights for your height.

You can also take a look at a height-weight chart that shows the ranges of underweight, normal and overweight for various heights:

Limitations of the IBW calculator

Remember that the values found with our ideal body weight calculator are not one hundred percent valid for all. As long as you are in the BMI normal weight range, you are fine - don't go on a strict diet just to reach that specific number!

Also, our IBW calculator is valid for adults only. Don't use it to find the proper weight range of kids - consult a specialist instead. Also, don't use it if you are pregnant. Use pregnancy weight gain calculator instead!

Other methods to findout your Ideal Weight?

Achieving the right number on the weighing scale involves different factors. It includes your height, muscle-fat ratio, body fat distribution, gender, and other physiological conditions.

There are several ways you can determine your ideal weight. The most common methods are:

  • Body Mass Index (Weight and Height) 
  • Waist-to-Hip Ratio (WHR)
  • Body Fat Percentage

While using these methods can provide you with a good estimate, it's important to note that one result may not necessarily mean you're unhealthy or fit. Each individual is different, so it's best to know how to use each method to address issues that are particular your body type.

Best Exercises for Weight Loss

Cardiovascular or Aerobic Workouts

While exercise is commonly recommended for losing weight, people should really focus more on fat loss. It's true you can lose weight from cutting down sweets and carbs and eating more vegetables into your diet. However, without exercise, you can lose significant amount of muscle which your body needs. Here are the top 2 exercises you should do to help you lose extra pounds.

Cardio or aerobic exercises are the most popular and effective way to lose fat.

Cardio workouts involve running, walking, cycling, swimming, or any continuous movement that burns calories and keeps your heart rate up.

You can do High Intensity Interval Training (HIIT) at least 15 to 20 minutes a day and still see noticeable results. If you can't workout everyday, try walking up and down the stairs. You won't lose pounds overnight, but it will definitely come in the long run. Increasing your daily movement will have an impact on your health, especially if you're the type who works in an office sitting all day.

Weight Lifting

Weight training may not burn as much calories as cardio workouts, but it's most effective in helping maintain your muscle mass during weight loss.

Moreover, higher muscle mass helps increase your metabolism, which in turn allow you to burn more calories even when you're at rest.[10]

Therefore lifting weights, also known as resistance training, helps you maintain muscle mass and strength to help keep the weight off.

Best Low-Impact Exercises You Should Try

For people who have joint problems, it's essential to start slow and try low-impact exercises. Some obese patients are also encouraged to start slow before moving to more moderate exercises.

Low-impact exercises warms up your muscles and joints to help them become more flexible as you become more active. This decreases the risk of bone and muscle injury, as well as body aches and pains.

According to Health.com, here's a list of low-impact workouts that can help prevent serious injuries:

  • Cycling (stationary or outdoor)
  • Elliptical training
  • Swimming
  • Kettlebell workouts
  • Rowing
  • Power Yoga

Taking Care of Your Health

There are many ways for you to track your ideal body weight. However, most of these methods aren't accurate when done alone at home. It's always better to consult your doctor for accuracy. Also consider having a thorough physical exam to rule out any other health conditions. Losing extra pounds is not an easy journey, but with the right tools and a good support group, you can definitely achieve your fitness goals.
