How to Use This Calculator

Select your preferred unit system - metric (kilograms and centimeters) or imperial (pounds and feet/inches).

Enter your height accurately. For imperial, enter feet and inches separately. Stand straight against a wall for the most accurate measurement.

Enter your weight. For best results, weigh yourself in the morning before eating, wearing minimal clothing.

Understanding Your Results

Your BMI score is shown with its corresponding health category. This gives you a general indication of whether your weight is appropriate for your height.

The healthy weight range shows the weight range that would give you a normal BMI. This can help set realistic weight goals.

Remember that BMI is just one indicator of health. Body composition, fitness level, and other factors are equally important. Consult a healthcare provider for a complete health assessment.

Frequently Asked Questions

What is BMI and how is it calculated?

Body Mass Index (BMI) is calculated by dividing your weight in kilograms by your height in meters squared (kg/m²). It's a simple screening tool to categorize weight status but doesn't directly measure body fat.

What are the BMI categories?

BMI categories are: Underweight (below 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). These ranges are the same for all adults regardless of age or gender.

Is BMI accurate for everyone?

BMI has limitations. It doesn't account for muscle mass, bone density, or body composition. Athletes may have a high BMI but low body fat, while older adults may have normal BMI but high body fat.

What is a healthy BMI range?

A healthy BMI is generally between 18.5 and 24.9. However, optimal weight depends on many factors including age, muscle mass, and overall health. Consult a healthcare provider for personalized guidance.

How do I calculate BMI in pounds and inches?

The formula for imperial units is: BMI = (weight in pounds × 703) ÷ (height in inches)². For example, a person who is 5'10" (70 inches) and weighs 160 lbs has a BMI of (160 × 703) ÷ (70 × 70) = 23.0, which is in the normal range.

What should I weigh for my height?

For a normal BMI (18.5-24.9), healthy weight ranges vary by height. At 5'4" it's 108-145 lbs, at 5'8" it's 125-163 lbs, at 6'0" it's 137-183 lbs. Our calculator shows your specific healthy weight range based on your height.

Is BMI different for men and women?

The BMI formula and categories are the same for men and women. However, women typically have more body fat than men at the same BMI. For a more accurate picture, consider body fat percentage or waist circumference alongside BMI.
