Start by drawing an oval to define Superman's head. Add a horizontal and vertical line through the middle of the oval, which will assist with the facial features' placement.
Draw two vertical lines on either side of the cross to define the width of Superman's shoulders. Add two more lines across the top and the bottom of the oval to represent the neck and waist.
Now it's time to give Superman a muscular look by adding lines to define the muscles and details of the outfit. Draw the iconic Superman shield on his chest, which is an 'S' in a diamond shape.
Once you have perfected the drawing, outline it with a pen or marker and erase any excess lines. Color the drawing, using the traditional Superman colors of red, yellow, and blue.
