What Are The Measurements Of A 1/4 Sheet Cake?
Decorating By CakeCraze Updated 26 Aug 2006 , 3:50am by Gingoodies
This question is asked all the time. I'm not for certain, (because there always seems to be different answers) but I think they are:
1/4 - 9x13
1/2 - 11x15 or 12x18
Full - I'd like a deffinate anwer on this....I'd read somewhere that is was two 12x18 side by side??? Anyone know for sure?
Most people I know (not all) consider a 9"x13" to be the quarter and the 12"x18" to be a half. Then a full is 2 of the halves side by side frosted as one cake, unless you have an industrial size oven and can get one of those HUGE pans! (If so, I am SO freakin jealous!!) What you can charge totally depends on your area. A good way to set your prices is to look at bakeries in your area that you feel your product is comparable to. (Not Wal-Mart, haha! You are waaaaay better than that!)
I consider a 1/4 sheet cake to be the 9x13 (decided this after reading numerous posts and websites on the subject of sheet cake sizes). My price is $30 for one layer (serves 25), but if someone wants filled (torted), I have on my price sheet to add an addtional 20 cents per serving for filling of a sheet cake. So for the 1/4 sheet it would be $30 + $5 for the filling.
With regard to the 11"x15": I have used that as a half sheet because it works in my oven well until the new one is in, (got a new bigger oven waiting to be installed... it's killing me!)then I can switch to 12"x18" which is more fair as a half sheet. Anyway, I have heard others that refer to the 11"x15" as a third sheet. That's an idea!
I use for my 1/4 sheets a 9x13 pan. An 11x15 cake is my 1/2 sheet pan, and my full sheet pan is a 12x15 pan. However, others may have different opinions.
As for prices, you are best off calling a local bakery & ask them what they charge for their cakes because prices vary depending on area/location.
HTH
I've heard an 11x15 being a third as well. I made my Pepa's 80th birthday cake. It was 2 12x18's put together (one carrot and the other red velvet). I was so lucky, both cakes were the exact same height so no leveling was needed. I took pics because I never thought that would happen again.
I wish I was getting a new oven!
That's the reason why I payed the extra $ for Sears to come and install my dishwasher!
Oh I got the new oven..DH even installed it the night before Thanksgiving last. Be careful what you ask for!!!!! 
Wired it in wrong and blew it up...Had already given my old oven away...thankfully DH fryes the turkey every year so oven issue there, 
however all other oven items, and there were several, including a full size pan of dressing, we had about 25 people for dinner, were cooked on the grill outside. One of the best Thanksgiving we ever had.
I got a replacment part and DH fixed the oven...love it, and DH.
Mel,
What is this bigger oven? Tell me , is it a regular kitchen oven or commercial oven? Building a house and need information!!!!!!!!!
makingcakeintx: my husband also installed our new oven a couple of years ago... I was sooooo paranoid when using the oven the first few times. I was worried that something like that would happen to ours... everything was fine. I am glad your Thanksgiving turned out well. 
When I lived in OK, my oven was so small, I could not even put any of my cookie sheets in there! Now my DH installed a large (fits the 12x18 pans easily) double oven. Love it!!!!
This is my 2 cents worth. lol
All cakes are two layers of cake, one layer filling.
1/4 = 9x13 serves approx 25 $40
1/3 = 11x15 serves approx 35-40 $50
1/2 = 11 1/2 x 17 1/2 serves approx 50 $65
(I use a commercial low sided sheet pan)
Large 1/2 = 12x18 serves approx 60 $70
3/4 = 2 11x15 (side by side) serves 75-80 $85
Full = 2 1/2 sheets side by side serves 100 $115
