I am doing a wedding cake for around 75 to 150 people. I am new at this and I am not quite sure sizes of cakes. I want to do a round tired cake..Please any advice on sizes?
My favorite cake size for 3 tier is 6, 9, 12. This should feed about 70 then I would do a sheet cake for extra servings.
Just my 2 cents...
by the way do a search for "serving amounts" you will get a load of info on what to expect for each cake size.
You also can make 12", 10" 8" and 6". It will give you 120 servings and you can make a sheet cake to feed the remaining 30.
Here's a link to Wilton's serving guide:
Here's a link to options to serve 100 to 150:
I also go by the wilton wedding guide. I also never do sheet cakes at a wedding. It's just bluntly never really come up, once the bride finds out she can get a big, grand wedding cake for the same price as a sheet cake.
I also prefer making a big, grand wedding cake! The bigger the better!
