# Shoulder Peak To Knee Over Back

• Step 1: Draw in neck base girth and find shoulder peak that sits on the neck. Then draw in knee girth. To find the shoulder peak point, it is approximately 1.5 cm away when draw a perpendicular line from the neck to shoulder line.
• Step 2: Use the tape measure tool to measure over the back from the shoulder peak to the knee level.
• Step 3: Compare this measurement with the 3D scan output and see if it is comparable. If it is vastly different, replace the 3D scan output with your measured value.
