There is a strong emphasis on the central axis in symmetry since all of the information is reflected from there. This should be taken into consideration when designing with symmetry.

Symmetrical balance guarantees left to right balance, which is the most important aspect of balance. But there is more to balance than that. Balance from top to bottom is also important. Most images seem to be more stable if the bottom seems slightly heavier. If the top seems too heavy the composition can look unstable.

Balance between the center and the outsides of the image must also be considered. Fortunately our own sense of balance is usually good enough to feel when the balance in a composition is wrong. Pay attention to your own sense of balance and you will do well. Your sense of balance, like anything else, can be improved with practice and experience.
