12x18 is a half sheet
11x15 does not fit into the scheme of things....cakes were traditionally baked full sheet (24x18)and then cut to size...11x15 is a convenient size pan because it holds two cake mixes....13x9 is a quarter sheet if you cut it from a full sheet it would actually be 12x9 and not 13x9 Only very large bakeries actually bake real sheet cakes and cut from the sheet. Individual pan sizes have come along later for home bakers because of oven sizes in homes and cake mixes. That is why when you look at sheetcakes in bakeries that bake full sheets you will see that the 13x9 cake is smaller than your 13x9 because it is really smaller. But since it's your cake you can call it whatever you want to call it and they get a better deal when they buy from you than a big bakery anyway...lucky them!
Hi there, i'm having issues with figuring out size for my cake and i found this post! But i'm still unsure...
These are the two styles of cakes the clients would like to feed 100 people:
-- I was thinking of going a 2 layer 12"x18" half sheet cake
-- i was thinking a 2 layer 14" square cake? I know the top 14" layer will have to be cut to show like the raised platform...so will that be enough cake? Am i better to do a 16" square?
