I am in the process of ordering Dummy cakes from Dallas Foam. I was just wondering if y'all could tell me what the avarege size is for a round and square cake. I was thinking 8", but I wanted to make sure before I ordered.

Thank you
Connie

i usually go with 8 or 9"

I also noticed that they come 4" thick, would I need to order 2 or would that be too tall?

Thanks
Connie
