Silly Question: Is 9 X 13 A Professional Size Or
Decorating By Dana0323 Updated 2 Aug 2007 , 4:04pm by q2wheels
"quarter" and "half" sheets are variable terms, it will differ bakery to bakery. If you go to the restaurant supply place and buy a "full sheet pan", the industry standard is 18x24. It would follow then that a half sheet is 18x12 and a quarter sheet is 12x9. This is what I use, but not everyone. There is very little difference between 13x9 and 12x9 so use whatever pan you have 
I am a cake decorator/Baker at a bakery and KoryAKs info is totally correct...a quarter sheet cake serves 15 people, a half sheet cake serves 30 and a full sheet serves 60 people..At least that is our standards anyways..At home I use a 9X13 pan for a quarter sheet.
No question is every silly.
Here is some information that was given to me a few years back.
1/2 sheet to be 12 x 18 and you can get 40 - 48 pieces.
Full sheet pan Standard 24x16x2
3/4 sheet pan- 18X12X2
Half sheet pan Standard 16x12x2
Quarter sheet pan Standard 13x9
Quarter Sheets, Half Sheets, and Full Sheets Explained
The retail baking industry developed standard sizes for rectangular sheet cakes, beginning with their standard sheet pan size of 16 by 24 and dividing it into halves (half-sheet) or quarters (quarter-sheet). The manufacturers who supply paper and plastic items to the baking industry use these standard sizes to create a variety of cake boards, boxes, and domes.
In an effort to develop a unique market share, some manufacturers began promoting pans of slightly different sizes, selling mainly to home bakers through hobby and specialty stores. Since home bakers do not have the volume purchasing power of retail bakers, most of the paper and plastics manufacturers have not created boards or boxes to accommodate these sizes.
The bottom line: Boards and containers for sheet cakes will always be easier to find if you use the retail baking industry's standard size pans. You will save yourself a lot of frustration by sticking with the standards.
Baking and Paper Industry Standards; The sizes below are recognized as industry standards.
Quarter Sheet Cakes: 8 x 12 pan, 10 x 14 cardboard
Half Sheet Cakes: 12 x 16 pan, 13.5 to 14 x 18.5 cardboard
Full Sheet Cakes: 16 x 24 pan, 19 x 27 cardboard
Non-standard Sizes. These sizes are not standard sizes. Suitable boards and containers can be very difficult to find.
9 x 13 pan: We call it the large quarter size. Very few of the paper suppliers carry the boards (11 x 15) and boxes (12 x 16) for cakes made in 9 x 13 pans.
10 x 15 pan: Use the standard half sheet boards and boxes
11 x 15 pan: Use the standard half sheet boards and boxes
12 x 18 pan: We call it the large half size. This size pan will not fit in most home ovens. Wilton sells a set of 14 x 20 boards that can be used with this pan, but they sell no boxes. If you cannot locate a large half board (14 x 20) and box (14.5 x 20.5), you will have to use full sheet boards and boxes.
You know what...just to know! If you have regular 13X9 that you buy at some store it is not totally 13X9! My mom measured it the other day and it was slightly off! I thought that was funny information! LOL So I guess If you want a good size pan do Wilton or Magic Line!
I highly recommend the Magic Line 9x13 pan if you plan on doing cakes for people other than yourself. The 9x13 pan you have probably has surved corners, and actually gets a little smaller/thinner at the corners. The Magic Line pans are 90 degree corners that look very professional.
WOW. no wonder I can never get nice corners on my 9 x 13... it's a wilton. I do have the 12x18 decorator's preferred, and that one has the same corners as the Magic Line .

Which Wilton pan? The Performance or Decorator Preferred?
I have the Decorator Preferred and my corners are perfectly square and the side perfectly perpendicular. Never have issues with my cake corners.
