RECTANGLES

The "golden ratio" for a pleasing to the eye rectangular shape is 50% width to length. Because of this, most accessories are designed around those sizes. If there is such a thing as a "standard size", this is as close as it gets. These are the most common:

• 12x24

• 14x28

• 15x30

• 16x32

• 18x36

• 20x40

• 22x44
