Can I use this calculator if I'm very muscular or athletic?

BMI may overestimate body fat in athletes or people with high muscle mass because it does not distinguish between muscle and fat. For a more complete assessment, consult a healthcare provider.

Does the CDC calculator work for children or teenagers?

No, this is an adult BMI calculator. For children and teens, BMI percentiles based on age and sex are used, which are different from the adult categories shown here.

What if my height or weight is outside the allowed ranges?

The calculator will not process entries below 3 feet (36 inches) or above 9 feet (108 inches), and similarly restricts weight to between 55 and 1,000 pounds (or 24.947 to 453.592 kg).

Is the BMI result a diagnosis of health status?

No, BMI is a screening measure and is not intended to diagnose disease or illness. A healthcare provider can interpret the result in the context of your overall health.

About this tool

What BMI Calculator for Men does

The CDC Adult BMI Calculator lets users determine their Body Mass Index by entering height and weight in either U.S. customary or metric units. The tool instantly outputs a BMI number, assigns a category (Underweight, Healthy Weight, Overweight, or Obesity including Class 1, 2, and 3), and provides a detailed interpretation of what the result means for health. It is designed for adults and includes clinical context about weight-related risk, making the numbers actionable rather than just a raw score. What sets the CDC version apart is its direct origin from a federal health agency, which lends immediate credibility. The interface is straightforward, offering clear unit options and explicit height and weight ranges before calculation. Unlike many commercial calculators, it avoids unnecessary upsells and presents a standardized BMI category table alongside plain-language explanations about maintaining a healthy weight and discussing results with a healthcare provider.
