Enter the tibia length into the calculator to estimate the knee height. This calculator is useful for anthropometric measurements and ergonomic assessments.
Knee Height Formula
The following formula is used to estimate the knee height based on the length of the tibia:
KH = TL * C
Variables:
- KH is the knee height (cm)
- TL is the tibia length (cm)
- C is the coefficient based on anthropometric data (dimensionless)
To estimate the knee height, multiply the tibia length by a coefficient derived from anthropometric data. The coefficient used in this example is 2.3.
What is Knee Height?
Knee height is a measure used in anthropometry to estimate body dimensions and composition. It is particularly useful for determining the stature of individuals who cannot stand, such as the elderly or those with mobility impairments. Knee height is correlated with overall height and can be used in various health and nutritional assessments.
How to Calculate Knee Height?
The following steps outline how to estimate the Knee Height.
- First, measure the tibia length (TL) from the protrusion below the kneecap to the top of the ankle bone.
- Next, use the coefficient (C) based on anthropometric data. In this example, we use 2.3.
- Apply the formula: KH = TL * C.
- Finally, calculate the Knee Height (KH) in centimeters.
- After measuring the tibia length and calculating the result, verify your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Tibia length (TL) = 36 cm
Using the coefficient (C) of 2.3, the estimated knee height (KH) would be:
KH = 36 cm * 2.3 = 82.8 cm
