Maintaining a healthy body weight is very important to all aspects of well being and can help you avoid serious health problems such as heart disease and type 2 diabetes.

One way of checking if YOU are at a healthy weight is to know your Body Mass Index (BMI). Your body mass index bmi is calculated by dividing your weight in kilograms by your height squared in metres. But no need to worry about that, you can calculate your body bmi with the Halls BMI calculator above.

Simply enter your height, weight, gender and age and the Halls BMI calculator will tell you if you have a high bmi, a low bmi or if you are within the healthy weight range. It also shows you how your weight compares to others of the same height and age.

Are you overweight? Maybe, if you get a bmi calculation that indicates you are, this may not always be accurate. Body Mass Index (BMI) can be misleading. This is because the BMI does not take into account your body composition. For example, your body fat percentage in comparison to your percentage of muscle mass is an important factor. Check out the mathematical formula to check your body fat percentage.

Can we throw our scales away then?

Why?

Well we should be thinking fat loss rather than weight loss.

No Moose, it's a whole combination of everything. Your BMI is important but so is your waist measurement and amount of body fat.

Calculate your BMI & Body Weight Comparison

An important area to look at is the weight percentiles, because they adjust for age and gender.

The older you get, the higher your BMI is allowed to be. For example, in people over age 50, a BMI score of 25 to 30 is still normal and indicates a healthy weight. I also believe the 45th percentile weight is a good estimate of your ideal weight.

Also, these height and weight charts and BMI charts show what the average population is like.

Some people say their body is a temple. Mine is more like a bouncy castle.

Why do I have two versions of a BMI calculator on halls.md? It's a leftover from year 2000, and I can't bring myself to delete old pages. So this page reminds me of the old-school html with tables, while the main BMI calculator is where new features will continue to appear. Some people like this one, with no graphics.

Way back in year 2000 when I created my body mass index calculator with analysis and custom formulas, the CDC was lagging. But to their credit, the science and their webpages and calculators have become quite good.

You can unfortunately still find rigid categories on CDC pages like this but, they have more useful things like a BMI percentiles calculator for children, which, reminds me to mention because it's not obvious: my Weight Percentiles calculator is VERY equivalent to a BMI percentile.

Recently I've been looking at other BMI calculators, for instance at Mayo Clinic, which disappoint me, not only because of the ads for their branded diet, but they refer to a 2013 WHO report, where various academics still lump together overweight and obesity into 'combined', which of course is less healthy than normal weight. Whenever you read a study abstract where the word "combined" is used in confusing ways, that's deliberate tricky wordsmithing.

What is the difference between overweight and obesity?

Well, overweight is having a Body Mass Index of between 25 and 29.9 and obese is a BMI of over 30.

So you wouldn't want to be called obese if you are just overweight.

I don't like the 25 to 29.9 definition. Not one bit.

Is this usable for kids?

Yes. Male or Female gender, adult or child, girls or boys, teenagers, pediatric usage is fine.
For under 18 year old, this calculator does very well.
Soon I will implement better adjustments for men over 50 or women.

Is this applicable in different countries?

Yes, it's useful in the USA, u.s., Canada, India, Philippines, Queensland, NZ and UK.

Preferences for units?

It has metric kg and cm, with age adjustments, advanced and accurate and can show 2 decimal points, and is quick online.
Imperial, you can work out your weight in pounds and your height in feet & inches, lbs and feet units measurements. Doesn't have stone yet. Perhaps I should.

By the way, this used to be titled detailed and Advanced bmi calculator, but I'm trying out a new title, which I hope isn't too confusing. I think it compares favorably to offical range or other popular bmi calculators like

nih gov (National Institute of Health), nhs, navy, oxford, kidshealth, ymca, webmd, yahoo, etc.

Of course you know that...

without using waist circumference measurement,
and not assessing the amount of muscle mass compared to body fat,
not using body frame size, type or including bone structure,
or other equation enhancements,

...BMI is too simple. You and I and everyone knows that this BMI formula, although a useful screening tool, is too simple.

I wouldn't recommend using BMI in the normal way during pregnancy. Realistic weight gain is to be expected. Follow my links to a bmi chart, graph and you can find information about Females, body fat, weight loss and goals, and so on. I have references pertaining to young adults, Asian considerations, anorexia and eating disorders, health concerns of diabetes, and equation usage and work by dietitions. But I'm not showing results of obese class, reverse calculation, z-score, calories, visual gimicks, quiz or youtube cats here.

I don't like mathematicals formulas. Why do you need to calculate your bmi?

Well, you could always just look in the mirror Moose.

I try to avoid things that make me look fat, like scales and mirrors and BMI calculations.

Why are Body Mass Index (BMI) measurements important?

Body Mass Index scores are a good indicator of whether you are at a healthy weight and how much body fat you have. Having a high bmi can increase your risk factors for certain diseases such as cardiovascular disease (or heart disease), high blood pressure and diabetes type 2.

The National Institute of Health (nih gov) use BMI scores to determine if you qualify for weight loss surgery. For those with a BMI of over 40 or those with a bmi range of over 35 with related health conditions (heart disease, diabetes type 2, sleep apnea and high blood pressure) qualify for weight loss surgery.

This one doesn’t give false overweight results like the CDC’s calculator.
