I am making a two tiered birthday cake and need 50 servings. I originally was going to do like a 9 inch on the bottom and a six on the top but not sure this is enough.

Can someone help please?

Here's a link to the chart I use to determine serving size

Thank you. I also get so nervous that people will run out of cake because sliced usually get cut too large.

I always tell them the serving size and I have a friend who gives out a diagram of how to cut a cake to get the appropriate servings. My clients have always said that the servings were large and they had cake leftover. I use party cake servings...1 1/2 X 2 on a cake that's a little over 4in high is a lot of cake!

I provide these documents printed out with every cake order (the serving guide/the how to cut diagram) and never have any problems with running out of cake. If they want bigger slices, they order more cake!

A standard serving is 1" x 2" x 4" (8 cu. in.). According to the Wilton wedding cake serving guide:

a 10" x 6" serves exactly 50.
