does anyone know where i can find the sheet cake pans they go by when you buy from say walmart? i guess what i am asking is if anyone knows where i can get a 12x8, 6x4, and a 3x2 cake pan. and are these even the right sizes for the full, half, and quarter sheets?

Everyone has a different size for what we call a full sheet .. I've always thought a full sheet cake was 2 - 11" x 15" pans side by side .. others say it's 2 - 12" x 18" side by side .. I'm not really sure what is correct .. I haven't seen any 12" x 8" cake pans but I'm sure some websites out there have them .. as far as 6"x4", never seen those before .. I've only seen 3" deep pans as far as 3"x2", I've seen those in round pans .. they're very small and usually used when doing the minature wedding cakes .. hope this helps some!

a full sheet is two 12x18's and a half is a 12x18. a 1/3 sheet is an 11x15 and a 1/4 sheet is a 9x13. hope this helps.
