These figures are based on the standard BMI scale and are a general guide only. BMI doesn’t account for muscle mass, bone density, or body composition, so speak with a healthcare provider for advice specific to you.
How Healthy Weight Is Calculated
This tool uses Body Mass Index (BMI), a simple ratio of weight to height, to estimate a healthy weight range for your height and to score your current weight against the standard categories.
Applying the healthy BMI range of 18.5 to 24.9 to your height gives the lower and upper bounds of the weight range shown on the right, which is how the category breakdown alongside it is calculated too.
Frequently Asked Questions
What is BMI and why is it used?
Body Mass Index is a quick screening measure that compares your weight to your height. It’s widely used because it’s simple to calculate, but it’s only a starting point, not a full picture of health.
Is BMI accurate for everyone?
Not always. BMI doesn’t distinguish between muscle and fat, so athletes or very muscular people can show a higher BMI without carrying excess body fat. It also doesn’t account for age, sex, or where fat is distributed on the body.
What’s a healthy BMI range?
For most adults, a BMI between 18.5 and 24.9 is considered within the healthy range. Below 18.5 is classed as underweight, 25.0 to 29.9 as overweight, and 30.0 or above as obese.
Should I use weight range or BMI to track progress?
Either works as a rough guide, but neither replaces a conversation with a doctor or dietitian, especially if you’re pregnant, an athlete, elderly, or under 18, since standard BMI categories aren’t designed for those groups.
