Ok here is probably a very stupid question but here goes anyway... What is the standard size for a sheet cake. I looked on the wilton site and it says 13 X 9 that seems kinda small. But then they have the 18 x 12 is that about right??
I am doing a basketball cake for my first paid cake. Its a grooms cake so they want it (3D Basketball) on a sheet cake. Thats a awful lot of cake not counting the wedding cake.. But i guess as long as they want to pay for it right.
So i guess my question is.. is 13 x 9 or 18 x 12 the standard sheet cake size???
Thanks in advance

Tina,
I don't know if there is a"standard" sheet cake. 
I think that it may depend on your area. But I make a lot of sheet cakes, and I usually sell the 11x15. That is what I consider a half sheet.
I would ask the customer what size cake they want. I hope that helps.

This question comes up a lot and people go by several different sizes. I go by this:
1/4 sheet= 9x13
1/2 sheet = 12x18
full sheet= 2 half sheets, side by side.
Some people call a 1/2 sheet the 11x15 and some call that size a 3/4 sheet. So I guess it just depends on how many servings you want. And again, that varies widely too.
Hope that helps a little.

Thanks everyone. This is just what i needed. Everyone was so helpful. Cleared everything up. Now i just need to find where i can buy them. Probably have to be somewhere online. I leave in a small town so cant find that around here.
Thanks again everyone

With square or rectangle cakes, it's easy to just do the math to figure your servings.....
11x15 cake: 2x2" servings = cut columns/rows of 5x7 = 35 servings
11x15 cake: 2x3" servings = cut columns/rows of 5x5 = 25 servings
12x18 cake: 2x2" servings = cut columns/rows of 6x9 = 54 servings
12x18 cake: 2x3" servings = cut columns/rows of 6x6 = 36 servings
These are based on a single layer cake. If you bake two layers, then you will probably cut the pieces into 1x3" pieces to yield different serving amounts.
Just do the math.....!
THank you! Final question...how many cups batter per size?
I use the chart as a guideline. I hardly ever use Wilton pans. You can tweak it to your needs.

I usually ask the customer how many servings they will need, and them give them the sizes from there. This usually works better since everyone has a different perspective on what size a "sheet" cake is.
