How to use the calculator
- Enter your total height in centimeters (cm) in the first input field.
- Enter your sitting height in centimeters (cm) in the second input field. To measure sitting height, sit on a flat surface with your legs stretched out straight and feet flat on the floor. Measure from the top of your head to the seat of the chair.
- Click the "Calculate" button to compute your sitting height ratio.
- The calculator will display your sitting height ratio as a percentage and provide an interpretation based on standard health guidelines.
What is sitting height ratio?
Sitting height ratio is a measure of body composition and is calculated as:
Sitting Height Ratio = (Sitting Height / Total Height) × 100%
This ratio helps in assessing body fat distribution. It's particularly useful in identifying central obesity (excess fat around the abdomen).
What are normal ranges?
- Adults: Typically 50-52% of total height
- Children: The ratio varies with age and sex, generally higher in younger children
When is this measurement useful?
Sitting height ratio is particularly useful in:
- Assessing nutritional status
- Identifying central adiposity (fat around the waist)
- Monitoring changes in body composition over time
- Differentiating between height loss due to spinal compression and loss of height in the lower extremities
