One of the principles of design, balance places elements on the page so that text and graphic elements are evenly distributed. Symmetrical balance is seen in perfectly centered compositions or those with mirror images. In a design with only two elements they would be almost identical or have nearly the same visual mass.
Symmetrical pages don't have to have the exact same text or images on each half. It's more about the overall look and feel. Each half would have about the same amount of text or the same number and size of images. Or, everything is aligned down the middle (center alignment). The opposite form of balance would be asymmetrical.
Also Known As: symmetric balance
Common Misspellings: symetrical
Examples: When folded in half vertically, the two halves of the page are visually equal or close to mirror images.
