A BMI chart is a simple table that helps you understand if your weight is healthy for your height. BMI stands for Body Mass Index, and it is a number that shows if you are underweight, normal weight, overweight, or obese. The BMI chart uses your height and weight to give you this number.
Why is BMI Important?
BMI is important because it gives you a quick idea of your body health. It is used by doctors, fitness trainers, and health experts. While it does not measure body fat directly, it helps to see if your weight is in a healthy range.

How to Calculate BMI?
You can calculate your BMI using this easy formula:
BMI = Weight (kg) ÷ Height (m) ²
Example:
If you weigh 70 kg and your height is 1.75 meters:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
You can also use online BMI calculators or check your number on a BMI chart.

How to Use the BMI Chart

Is BMI the Same for Everyone?
Not exactly. The BMI chart works well for most people, but it may not be right for:
- Children and teenagers: They need special BMI charts.
- Athletes or muscular people: They may have high BMI but low body fat.
- Older adults: They may have lost muscle, so BMI might not be accurate.
What Should You Do After Checking Your BMI?
Here are simple tips depending on your BMI category:
- Underweight: Eat more healthy food, and add proteins and good fats.
- Normal weight: Maintain your current weight with a balanced diet and regular exercise.
- Overweight or Obese: Try to lose weight by eating healthy and being active.
Always talk to a doctor before starting any diet or fitness plan.
Tips to Keep a Healthy BMI
- Eat a balanced diet with fruits, vegetables, and whole grains.
- Exercise for at least 30 minutes daily.
- Drink plenty of water.
- Get enough sleep.
- Avoid junk food and sugary drinks.
Limits of the BMI Chart
While the BMI chart is useful, it has some limits:
- It does not show body fat percentage.
- It does not show where fat is stored (belly fat is riskier).
- It may misjudge very fit people or those with low muscle.
That’s why some experts also use waist size, body fat tests, or health check-ups to get a better picture.
Better Health, Not Just a Better Number
Having a healthy BMI is a good start, but your overall health is more than just a number. Focus on how you feel, your energy, sleep, and mental wellness. Use the BMI chart as a tool, not a rule.
