A Body Mass Index (BMI) chart is a visual tool that helps assess whether an individual's weight falls within a healthy range based on their height. The chart categorizes BMI values into different health ranges, making it easier to interpret the results:

• Underweight: BMI less than 18.5
• Normal weight: BMI between 18.5 and 24.9
• Overweight: BMI between 25 and 29.9
• Obese: BMI 30 or higher

The chart is commonly color-coded for quick reference, highlighting each range with distinct visual cues. It is used for general health screening but does not account for factors like muscle mass, body composition, or distribution of fat.
