How Big Is A Whole Sheet, Half Sheet, 1/4 Sheet?
Decorating By catscratchfever Updated 27 Sep 2006 , 6:07pm by CustomCakesBySharon
I'm always confused when people say those because I don't even know how big a full sheet is. TIA!
don't feel bad....i haven't a clue either! :0P
This topic comes up a lot and it seems people have different answers depending on what they personally make.
This is what I go by: And I torte the layers.
1/4 sheet- 9" x 13", one layer.
double 1/4 sheet- two 9" x 13"'s stacked on top of each other.
1/2 sheet- 12" x 18", one layer.
full sheet- two half sheets, side by side, each one layer.
Some do a 3/4 sheet, 11" x 15". Some call that a half sheet.
Hope that helps!

I was just asked to do a sheet cake. I think I am going for 2 9x13 side by side. So 18x26.
(will I find a board big enough!?!?!?!)
I suppose that depends on the dimensions of your cookie sheet. Most cookie sheets are either flat or only about an inch high so I personally wouldn't use that to bake any cakes. I go by the dimensions I stated above but my pans are 2" high. Some pans are 3" high.

Actually, that doesnt make sense - it would be either 9x26 or 13x18...hm
I like round better 
When doing a 11 x 15 pan how many flower nails should I use? I haven't bake a cake this large yet but am planning to do so within the week. Thanks, Pat
wow! that makes a full sheet one big darn cake....i've made em this big before (and actually am doing another one like this for this w/e), but it is hard finding board big enuff
pbertone1005 - i don't use any flower nails in the 11X15 or 12X18 pans.....they always come out just fine.....i think it's because they're only 2" high.....when i use my 3" high rounds, i use either a flower nail or heating core (depending on the size of the round)
I don't use flower nails in my pans either. For the full sheet board, I had my DH cut a piece of plywood big enough. Man, was it heavy. But the cake surely won't crack! 
It's the "Roys" hawaiian flower cake in my profile to give you an idea. That one is two 12x18 cakes side by side then another one stacked on top.
You can buy cardboard full sheet boards but I would highly recommend doubling or even tripling it for strength.

this information was given to me - this is what RETAIL consider customer size cakes:
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.
thx sooooo much leana! that's very helpful!
My 12x18 fits fine in my oven with some room left over.
My cake supply store sells boards and boxes 14x19 and 14x20.
When I did the Batman with the Moon, I used 11x15 side by side which came out to 22x15.
my 12X18 fits in my oven fine too.....i didn't realize not everyone's oven is big enuff
