PLEASE NOTE: The measurements above are just a guide. Your chair might be lower like a bean bag or wider. You can measure any chair at home and divide the measurement into 10 to figure out the size of your chair drawing.
Step 1: Draw your front view at 1:10 scale.
REMEMBER: Seat height is 4.6cm and seat width is minimum 4.5cm.
Step 2: Draw your vertical and horizontal projection lines.
Step 3: Draw your top view lined up with the projection lines.
REMEMBER: Seat depth is minimum 4.3cm.
Step 4: Draw your side view lined up with the projection lines.
