BMI Calculation for Height 5'4" and Weight 65.6 kg
For an adult who is 5'4" tall (162.56 cm) and weighs 65.6 kg, the BMI is 24.8 kg/m², which falls within the healthy weight range (18.5-24.9 kg/m²). 1
Calculation Method
- Height conversion: 5'4" = 64 inches = 162.56 cm = 1.6256 meters 2
- BMI formula: weight (kg) / [height (m)]² 2
- Calculation: 65.6 kg / (1.6256 m)² = 65.6 / 2.64 = 24.8 kg/m² 2
BMI Classification
This BMI of 24.8 kg/m² is classified as "healthy weight" or "normal weight," falling just below the overweight threshold of 25.0 kg/m². 1, 3
Standard BMI Categories:
- Healthy weight: BMI 18.5-24.9 kg/m² 1, 3
- Overweight: BMI 25.0-29.9 kg/m² 1, 2
- Obesity Class I: BMI 30.0-34.9 kg/m² 1, 2
- Obesity Class II: BMI 35.0-39.9 kg/m² 1, 2
- Obesity Class III: BMI ≥40.0 kg/m² 1, 2
Clinical Significance
Maintaining a BMI between 18.5 and 25.0 kg/m² is associated with the lowest risk of cancer, cardiovascular disease, diabetes, stroke, and overall mortality. 1, 3
- At BMI 24.8 kg/m², this individual is at the upper end of the healthy weight range, with minimal increased health risk compared to those in the mid-range of normal BMI 1
- Disease risk increases significantly once BMI exceeds 25.0 kg/m², making weight maintenance particularly important at this level 1
Important Caveats
For Asian populations, lower BMI thresholds apply—overweight is defined as BMI ≥23.0 kg/m² and obesity as BMI ≥25.0 kg/m²—meaning this BMI of 24.8 kg/m² would be classified as overweight if the individual is of Asian descent. 2, 3
- BMI does not distinguish between lean mass and fat mass, potentially misclassifying individuals with high muscle mass 3, 4
- Waist circumference should be measured alongside BMI for complete risk assessment: >88 cm (>35 inches) for women or >102 cm (>40 inches) for men indicates increased cardiovascular risk even at normal BMI 1, 3
