Reference table showing BMI values for every height from 4'10" to 6'6" and weights from 100 to 300 lbs. Color-coded by BMI category.
| Category | BMI Range | Health Risk |
|---|---|---|
| Underweight | Below 18.5 | Increased risk of nutritional deficiency |
| Normal weight | 18.5 -- 24.9 | Lowest health risk |
| Overweight | 25.0 -- 29.9 | Moderate health risk |
| Obese | 30.0 and above | High health risk |
Find your height in the left column, then read across to find the weight closest to yours. The color indicates your BMI category. BMI is calculated as: BMI = (Weight in lbs x 703) / (Height in inches)^2
Step 1: Find your height in the leftmost column of the table.
Step 2: Read across the row to find the column with your weight (or the weight closest to yours).
Step 3: The number in the cell is your approximate BMI value.
Step 4: Check the cell color to see your BMI category: blue for underweight, green for normal weight, yellow for overweight, and red for obese.

The table below shows the healthy weight range (BMI 18.5 to 24.9) for each height. Staying within this range is associated with the lowest risk of weight-related health conditions.

Body Mass Index (BMI) is a screening tool that uses height and weight to estimate body fat. It was developed by Belgian mathematician Adolphe Quetelet in the 1830s and remains one of the most widely used health metrics today. While BMI does not directly measure body fat percentage, it correlates well with more direct measures of body fat for most people.
BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters. In imperial units, the formula is: weight in pounds multiplied by 703, divided by height in inches squared. The resulting number falls into one of four main categories: underweight (below 18.5), normal weight (18.5 to 24.9), overweight (25.0 to 29.9), and obese (30.0 and above).
BMI is a useful screening tool, but it has important limitations. It does not distinguish between muscle mass and fat mass, so muscular athletes may have a high BMI despite low body fat. It does not account for fat distribution -- visceral fat around the organs is more dangerous than subcutaneous fat under the skin. BMI also does not consider age, sex, ethnicity, or bone density, all of which affect the relationship between BMI and health risk.
For a more comprehensive assessment, consider combining BMI with waist circumference, the waist-to-hip ratio, or body fat percentage measurements. These additional metrics provide a fuller picture of health risk.
A healthy BMI is between 18.5 and 24.9. This range is associated with the lowest risk of weight-related health conditions such as heart disease, type 2 diabetes, and certain cancers.
BMI = weight (kg) / height (m) squared. In imperial units: BMI = (weight in lbs x 703) / (height in inches) squared. For example, a person who is 5'10" (70 inches) and weighs 170 lbs has a BMI of (170 x 703) / (70 x 70) = 24.4.
BMI may overestimate body fat in muscular individuals because it cannot distinguish between muscle and fat. A bodybuilder with low body fat but high muscle mass may have an "overweight" BMI. For athletes, body fat percentage or DEXA scans are more accurate.
The standard BMI categories were developed primarily from studies of European populations. Research shows that health risks may occur at lower BMI values in Asian populations and at higher values in Black populations. Some countries use adjusted thresholds.
The formula is the same, but interpretation differs. For children and teens (ages 2-19), BMI is compared to age-and-sex-specific percentiles using CDC growth charts. See our BMI for Children & Teens calculator.
A BMI of 30 or higher is classified as obese. Obesity is further divided into Class I (30-34.9), Class II (35-39.9), and Class III or severe obesity (40 and above).
Yes. A BMI below 18.5 is classified as underweight and may indicate malnutrition, an eating disorder, or other health issues. Being underweight increases the risk of osteoporosis, weakened immune function, and fertility problems.
Both are useful. BMI provides a general screening, while waist circumference specifically assesses abdominal fat, which is a stronger predictor of cardiovascular risk. Using both gives a more complete health picture.
There is no strict rule, but checking every few months is reasonable if you are working on weight management. Annual checks during routine physical exams are sufficient for most adults.
