BMI (Body Mass Index) is a ratio of weight to height squared, used as a population-level screening tool for weight categories. Enter your height and weight below for your BMI, category, and healthy weight range, then see what BMI cannot: your actual body composition.

Your Stats
Your BMI: 25.8 (Overweight)
A BMI of 25.8 falls in the overweight range (25 to 29.9). Modest reductions in weight through diet and exercise can meaningfully improve health outcomes.
Healthy weight range for your height: 122 to 164 lbs. That is about 6 lbs above the top of the range. BMI does not distinguish muscle from fat. FitCommit scans your body composition so you track what BMI cannot see.
Scan my body compositionThe World Health Organization (WHO) defines these BMI categories. Note that BMI is a screening tool, not a diagnostic measure. Body fat percentage, waist circumference, and other metabolic markers provide a more complete picture.
| BMI Range | Category | Health Implication |
|---|---|---|
| Below 18.5 | Underweight | May indicate nutritional deficiency or illness |
| 18.5 to 24.9 | Normal | Associated with lowest health risk in population studies |
| 25.0 to 29.9 | Overweight | Modestly elevated risk; often reversible with lifestyle changes |
| 30.0 to 34.9 | Obese Class I | Elevated risk of cardiovascular disease and type 2 diabetes |
| 35.0 to 39.9 | Obese Class II | High risk; medical evaluation recommended |
| 40.0 and above | Obese Class III | Very high risk; comprehensive medical intervention advised |
Healthy BMI (18.5 to 24.9) translates to these weight ranges depending on height.

| 5'3" | 104 lbs | 141 lbs | 37 lbs |
| 5'4" | 108 lbs | 145 lbs | 37 lbs |
| 5'5" | 111 lbs | 150 lbs | 39 lbs |
| 5'6" | 115 lbs | 154 lbs | 39 lbs |
| 5'7" | 118 lbs | 159 lbs | 41 lbs |
| 5'8" | 122 lbs | 164 lbs | 42 lbs |

| 6'1" | 140 lbs | 189 lbs | 49 lbs |
| 6'2" | 144 lbs | 194 lbs | 50 lbs |

BMI uses the following formula for imperial measurements:
BMI = (weight in lbs / height in inches squared) x 703
Example: A person who is 5'10" (70 inches) and weighs 180 lbs has a BMI of 25.8.
BMI does not distinguish between muscle and fat. A muscular athlete may have a high BMI while having low body fat. Always consider body composition alongside BMI.
BMI is a quick, cost-free screening tool suitable for tracking population health trends and identifying individuals who may benefit from further evaluation.
