The 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.
| Height | Low (BMI 18.5) | High (BMI 24.9) | Range |
|---|---|---|---|
| 4'10" | 89 lbs | 119 lbs | 30 lbs |
| 4'11" | 92 lbs | 123 lbs | 31 lbs |
| 5'0" | 95 lbs | 127 lbs | 32 lbs |
| 5'1" | 98 lbs | 132 lbs | 34 lbs |
| 5'2" | 101 lbs | 136 lbs | 35 lbs |
| 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 |
| 5'9" | 125 lbs | 169 lbs | 44 lbs |
| 5'10" | 129 lbs | 174 lbs | 45 lbs |
| 5'11" | 133 lbs | 179 lbs | 46 lbs |
| 6'0" | 136 lbs | 184 lbs | 48 lbs |
| 6'1" | 140 lbs | 189 lbs | 49 lbs |
| 6'2" | 144 lbs | 194 lbs | 50 lbs |
| 6'3" | 148 lbs | 199 lbs | 51 lbs |
| 6'4" | 152 lbs | 205 lbs | 53 lbs |
| 6'5" | 156 lbs | 210 lbs | 54 lbs |
| 6'6" | 160 lbs | 215 lbs | 55 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.
