BMI helps assess weight-related health risks
Based on height and weight measurements
Using the BMI Calculator is simple and quick. Follow these steps:
Enter your Height (in cm):
Add your height between 100 and 250 centimeters.
Enter your Weight (in kg):
Input your current weight between 30 and 200 kilograms.
Click “Calculate BMI”:
Instantly see your BMI value and weight category (Underweight, Normal, Overweight, or Obese).
Understand Your Result:
BMI < 18.5 → Underweight
18.5–24.9 → Normal weight
25–29.9 → Overweight
≥30 → Obese
Use the Information Wisely:
The BMI gives a general indication of body fat, but it doesn’t account for muscle mass or bone density. Use it as a starting point to understand your health status and adjust your diet or exercise routine accordingly.
The Body Mass Index (BMI) Calculator is a scientifically recognized tool used to estimate whether your body weight is in a healthy range relative to your height. It provides a numerical value based on the ratio of weight to height, offering a quick and accessible way to assess general health and identify potential weight-related risks.
BMI stands for Body Mass Index. It’s calculated using the formula:
BMI = weight (kg) ÷ [height (m)]²
For example, if someone weighs 70 kg and is 170 cm tall, their BMI would be:
70 ÷ (1.7 × 1.7) = 24.2
This value helps classify individuals into categories such as Underweight, Normal Weight, Overweight, or Obese, according to World Health Organization (WHO) standards. These categories serve as a useful screening tool for identifying potential health concerns.
BMI is widely used by doctors, fitness trainers, and nutrition experts as an initial indicator of a person’s body composition and potential risk for lifestyle-related diseases. Maintaining a healthy BMI reduces the chances of developing issues such as:
Heart disease
Diabetes
High blood pressure
Joint problems
Certain cancers
However, BMI should not be used as the sole indicator of health. It does not measure muscle mass, body fat percentage, or distribution of fat — all important components of true fitness. For example, athletes with higher muscle mass may have a “high BMI” but still be in excellent health.
The BMI Calculator on this page simplifies the process — no manual math required. Just enter your height and weight, and the calculator instantly displays your BMI score along with an explanation of what it means. It uses color-coded visuals to help you understand your result easily, showing where you fall on the scale from underweight to obese.
This instant feedback helps you:
Monitor your current health status
Set realistic weight goals
Adjust your nutrition and fitness routines
Track progress over time
While BMI is a valuable health screening tool, it does not account for:
Muscle vs. fat ratio (athletes may show as overweight)
Age and gender differences in body composition
Ethnic variations in body fat distribution
Therefore, it’s best to use BMI alongside other health metrics like waist circumference, body fat percentage, and overall lifestyle habits for a comprehensive assessment.
Eat a balanced diet rich in fruits, vegetables, lean proteins, and whole grains.
Stay physically active — at least 150 minutes of moderate exercise weekly.
Get adequate sleep and manage stress effectively.
Avoid excessive sugar and processed foods.
Regularly track your progress using this BMI calculator.
The BMI Calculator is a convenient and effective starting point for anyone looking to evaluate their weight in relation to health. Whether your goal is weight loss, maintenance, or improvement of overall fitness, understanding your BMI is the first step toward a healthier you.
