I almost ordered a 16" round pan but luckily realised it won't fit in my oven, by about 1/2". I would like to get a half round pan, but Fat Daddio's smallest looks like its 18". Shall I just get that and cut 1" off the edge when baked? Any other manufacturers you know of? I can only find this brand on GSA, which is where I am ordering from...

I like to order from cakepan4less.com
here is a link to their 1/2 pan page and they have 16"

Many, many yrs ago I had 1/2 round pans 16" & 18" from Magic Line. Just a word of caution. The two 1/2s put together never made a perfect circle I had to cut a 1" strip to put in the middle so it was *almost* round. Otherwise I had an oval Not much help when you have to make an extra small sq cake just to fill out the round. Then you have extra cake going to waste

Thank you for your replies!
Putting 2 halves together and not making a circle doesn't sound good...hopefully things have changed nowadays...
