This guide (from the Wilton website) shows how to cut wedding cake tiers into pieces approximately 1 inch x 2 inches. Most of my cakes have tiers that are about 4 inches tall, so the servings are not as small as it may seem. For party cakes, slices should be a little larger ~ about 1 1/2 inches x 2 inches, but cut in the same pattern as shown below.
Before cutting the top tier, make sure that the bride and groom want it served. Sometimes the top tier is saved for the first anniversary. Start cutting and serving from the top tier and work your way down.

Round Tiers:
Move in two inches from the tier's outer edge; cut a circle and then slice 1 in. pieces within the circle. Now move in another 2 in., cut another circle, slice 1 in. pieces and so on until the tier is completely cut. The center core of each tier and the small top tier can be cut into 3rds, 4ths, and 6ths, depending on size. A 6 in. round should be simply cut like a pie and will serve up to 12.
Square Tiers:
Move in 2 in. from the outer edge and cut across. Then slice 1 in. pieces of cake. Now move in another 2 in. and slice again until the entire tier is cut.
