The body mass index (BMI) is a simple measure that can help you determine whether you’re at a healthy weight or not. It divides your weight in kilograms by your height in meters squared, so it’s not surprising that the BMI calculator is one of the most commonly used health tools.
But how useful is it? And what does it mean if your BMI is too high? Read on for everything you need to know about this handy too.
BMI is the most commonly used tool for measuring a person’s body fat. It can be calculated using a person’s height and weight, which makes it easy to measure.
The BMI formula is simple and is as follows: Weight in kilograms divided by height in meters squared (kg/m2).
For example, if you are 170 cms tall (1.7m) and your weight is 85 kgs, your BMI would be: 85 divided by 1.7 squared = 29.4. Therefore, your BMI is 29.4.
As you can see, it is easy to follow the BMI formula and calculate your own BMI with a simple calculator.
The US Centers for Disease Control and Prevention (CDC) has an interactive tool to help calculate your BMI. It uses the same BMI formula noted above. To use it, go to the BMI calculator.
The BMI calculator is easy to use: You enter your height in feet or inches; then enter your weight in pounds or kilograms; and finally, click “Calculate.” The BMI calculator will automatically calculate your BMI and display a BMI chart with the results.
The first step is to use a BMI calculator using the BMI formula and calculate your BMI. The next step is to check it against a BMI chart. A BMI chart will have different ranges of BMI numbers and will show the ranges for healthy, overweight or obese.
If your BMI range falls in the BMI chart in the range of 18.5-24.9, you’re in the “normal” range. Your weight is not considered to be overweight or obese by the scientific community, but it can still affects your health in many ways.
Generally, having a standard BMI per the BMI chart means that you are at a healthy weight for your height and age.
However, there are some exceptions: If you’re an athlete who exercises regularly or has an active lifestyle, you may have a higher-than-average muscle mass which can give you a high BMI and the appearance of being heavier than you are. The opposite can also happen, if you have little muscle mass and low body fat content (which would indicate being underweight), this could also cause someone to fall into this category when they shouldn’t necessarily be classified as “normal”.
If someone’s BMI is between the 25-29 range in the BMI chart, they are considered overweight; if their BMI goes above 30, they fall within obesity territory.
Here is a BMI chart based on WHO guidelines:
If your BMI as per a BMI calculator is 25 or above, then it indicates that you are in the overweight range and should look to reduce your BMI within the healthy range. Similarly, if your BMI as per a BMI calculator is 30 or above, then it indicates that you are in the obese range and should look to reduce your BMI towards the healthy range.
While the BMI formula is the same for everyone, the BMI chart to use is different for people of South Asian descent. The reason for this is that studies have shown that South Asians are more susceptible to the adverse effects of being overweight, including type 2 diabetes and heart disease at lower BMIs.
Refer to the below BMI chart for South Asians and Indians. Remember that the BMI formula remains the same as what we’ve discussed earlier.
If your BMI as per a BMI calculator is 23 or above, then it indicates that you are in the overweight range and should look to reduce your BMI within the healthy range. Similarly, if your BMI as per a BMI calculator is 25 or above, then it indicates that you are in the obese range and should look to reduce your BMI towards the healthy range.

Having a high BMI is associated with high blood pressure, high cholesterol and diabetes. All of these conditions can lead to heart disease and stroke. High BMI is also linked to some cancers, especially breast cancer. As your waist measurement increases, the risk of developing type 2 diabetes also increases significantly.
You may have sleep apnea if your BMI is 35 or greater; this condition causes you to stop breathing for short periods during sleep because you have too much fat in the neck area to allow it to expand during inhalation. This condition can be treated through lifestyle changes such as losing weight (if overweight) and increasing physical activity levels.
Obese people are more likely to develop a wide range of illnesses and ailments, including the following:
BMI is valuable in many ways given its simplicity and how easy the BMI formula is to use and interpret for most people. For example, it can be used as an easy screening tool to identify people who may be at risk for obesity-related health problems and then motivate those individuals to make healthier choices about nutrition and physical activity that lead to weight loss (or maintenance) over time. It also helps researchers track the prevalence of obesity in populations so they can better understand how prevention efforts are working (or not).
A BMI calculator can give an accurate picture of whether someone is overweight or obese. One study found that people whose BMIs were at least 30 had nearly double the risk of dying over six years compared with people with BMIs below 25.
A BMI calculator is a good starting point and an indicator of whether or not you’re overweight. However, it’s not perfect.
As the BMI formula is purely based on height and weight, it does not account for muscle mass, which can make it appear that you’re overweight if you have a lot of muscle mass. On the other hand, if all your weight comes from fat instead of muscle – as tends to be the case in older adults and sedentary people – BMI can underestimate your body fat content because it ignores how much fat is around your organs (visceral fat).
The simple answer is yes.
We have seen that the BMI formula is purely based on height and weight. BMI doesn’t consider important factors like fitness level, genetics, and body fat distribution. Think of a BMI calculator more as a starting point.
There are other better measures to track your health, such as:
There’s no denying that BMI is flawed as it’s too simplistic and the BMI formula only considers height and weight. But due to its ease of use, it remains an essential tool in the fight against obesity. A BMI calculator is a simple way to take stock of your health and identify whether or not you should make some lifestyle changes.
