# Side Arm Length

• Step 1: Draw in armscye and wrist girth to create an accurate guide to take side arm length measurement.
• Step 2: Use straight tape measure tool to measure from peak of the shoulder to outer wrist measurement, along the side of the arm.
• Step 3: Compare this measurement with the 3D scan output and see if it makes sense. If it is vastly different, replace the 3D scan output with your measured value.
