How many people can I serve with a four tiered round wedding cake, the bottom round is 14 x 3 high and gradually goes down two inches per tier. Each tier is 6 inches thick.
Here is the wilton serving guide for wedding cakes for 3 in. pans:
Here is the serving guide for earlenes (slightly larger slices):
If each 6" tall tier will be cut into 1" x 2" x 6" servings, the chart suggestions are accurate (although 6" tall slices won't fit on dessert-sized plates).
If each 6" tall tier has a board in the middle at 3" and will be cut into 1" x 2" x 3" servings, they would serve double what the charts indicate.
Here, just punch in your pan sizes and it will give you all you need!!!
