The "half knee" measurement refers to the width of the knee, typically taken when drafting sewing patterns or taking measurements for tailored clothing. It is not the distance from the crotch to the knee. To clarify, measuring half knee refers to finding the width of the knee and then dividing that measurement by two. Here's how:
Steps to Measure Half Knee:
- Position the Subject: Have the person stand straight with their feet slightly apart (shoulder-width is ideal).
- Locate the Knee: Identify the fullest part of the knee joint. This is where you'll take the circumference measurement.
- Measure the Knee Circumference: Using a flexible measuring tape, wrap it around the fullest part of the knee. Ensure the tape is snug but not too tight. The person should be able to move comfortably. The tape measure should be horizontal, parallel to the floor.
- Calculate Half Knee: Divide the knee circumference measurement by two.
Example:
If the knee circumference measures 36 cm, the half knee measurement is 36 cm / 2 = 18 cm.
Why is Half Knee Measured?
- Pattern Making: It's a crucial measurement for tailoring pants, skirts, or dresses that fit well around the knee area.
- Garment Alterations: Knowing the half knee measurement helps in altering existing garments to achieve a better fit.
- Custom Clothing: Ensures accurate fitting when creating custom-made clothing.
Important Considerations:
- Accuracy: Ensure the measuring tape is level and snug for an accurate reading.
- Consistent Units: Use the same unit of measurement (e.g., centimeters or inches) throughout the process.
- Posture: The person's posture should be natural. Avoid slouching or stiffness, as this can affect the measurement.
By following these steps, you can accurately measure the half knee for various tailoring and garment-related purposes.
