Positioning the Eyes
A common mistake in drawing eyes is to place them too high on the head. The eyes are located halfway between the top of the head, excluding the hair, and the chin. Once you’ve established how high or low to place the eyes, you must determine how wide to make the eyes and how far apart to place.
To do this, divide the head into equal vertical parts. The width of the head, excluding the ears, is approximately ten eyes wide. Therefore, each of the ten divisions is equal to the width of one eye.
Please note in the picture below the portions of the eyes. When the eyes are placed correctly, there will be one eye width between them and one width from the sides of the head to the corner of each eye.
