I have a lady at work that would like a round 2 tier cake for her daughters birthday, and she needs to feed 45 -50 people. Now my question is how big do i make each tier I was thinking that a 10 inch tier on the bottom and 8 inch tier on top would be enough but i'm not sure. what do I do??? What size do i make it to feed that amount of people?

there is a size guide in the articles section that should help.
Here is the link

10 and 8 will feed 50.
