Hi you guys!

I've been lurking on this site for a few weeks now, and absolutly LOVE IT!
I have a rather dumb question. When people say 1/4, 1/2 and Full Sheet, What are the dimensions of each? For ex., is a 1/4 sheet a 9x13? etc.

Please help. I have an order for Tuesday and she wants dimensions, and I just don't know.

Thank you,

Welcome to CC, someone correct me on this but I believe the 1/4 is 9x13, the 1/2 is 12x18, and the full is (2)12x18. And I know everyone will tell you, no question is dumb, we never know until we ask and good luck with your cake

First let me say, welcome to CC !! It's a wonderful informative place to be

Now about sheet cakes sizes, different people have different interpretations for sizes.. here is one that I found on the internet... there are many others that all have variances...


1/4 Sheet (8"x 12") serves 20-24
1/2 Sheet (12"x 16") serves 40-48
Full Sheet (16"x 24") serves 80-96

I've always thought a 9 x 13 was a 1/4 sheet.

Welcome to CC! I have always used 9x13 for a 1/4 sheet, 11x15 for a 1/2 sheet, and since I don't have a full sheet pan I just put 2 11x15's together. I have seen so many different interpretations, even the bakery here uses different sizes than I do.

Thank you guys so much. I've been saying that a 9x13 was a 1/4 sheet. So at least I've been right about that. I'm sure I'll have a bunch more questions in the upcoming weeks and months for I'm finally getting business.

Thanks again, and thanks for all the warm welcomes. I look forward to getting to know you all.

I asked the same question when I first started too. For simplicity reasons I just use 1/4 sheet is 9X13 and 1/2 sheet I use 2 9X13 and 3/4 is 3 and a full sheet is 4 9x13's. There were other people who said they did this also for simplicity reasons and it has worked well for me and it's easy to quote people for it. As far as serving sizes - I'd have to look them up.
