What Is BMI (Body Mass Index)?

BMI stands for Body Mass Index. It’s a number that tells you if your weight is:

  • Too low (underweight)
  • Healthy (normal)
  • Too high (overweight or obesity)

Doctors and fitness experts use BMI to check your health status quickly. It is not perfect, but it’s a good first step to know if you need to gain or lose weight.

The formula is:

BMI = Weight (kg) ÷ Height (m²)

But don’t worry. Our BMI calculator does all the work for you. Just add:

  • Your gender (male or female)
  • Your age (like 25)
  • Your height (in cm, like 170)
  • Your weight (in kg, like 70)

Click “Calculate” and you’ll see your BMI number with a color scale:

  • Yellow: Underweight
  • Green: Normal
  • Orange: Overweight
  • Red: Obesity

Men usually have more muscle mass. But BMI is still a good tool for them.
This BMI calculator for men helps you:

  • Check if your weight is in a healthy range
  • Plan fat loss or muscle gain
  • Avoid health risks like heart disease or diabetes

Just click Male, enter your details, and get your BMI.

Women often have different body shapes and fat levels, but BMI still works well.
This BMI calculator for women helps you:

  • Know if your weight is in a safe zone
  • Plan your fitness or diet journey
  • Stay strong, healthy, and confident

Select Female, add your info, and see your result.

Why Checking Your BMI Is Important

Knowing your BMI can help you:

  • Know if your weight is safe for your height
  • Take early steps to avoid sickness
  • Set better health and fitness goals
  • Improve your eating and activity habits

Even small changes in BMI can affect your heart, energy, sleep, and overall life.

BMI is Just a Start

Remember, BMI is not everything. It doesn’t check:

  • Muscle vs. fat
  • Bone size
  • Where fat is stored in the body

So it’s good to use BMI along with other checks like:

  • Waist size
  • Body fat %
  • Diet and activity

But BMI still gives a quick and helpful picture of your body status.
