Is 9 X 13 A 1/4 Sheet Cake? How Big Is 1/2 Sheet Cake?
Decorating By DEBBIE157 Updated 10 Oct 2013 , 3:05pm by SweetSinsationz

There is no right or wrong answer to this because every region seems to have different standards. The following are the ones I seem to see the most and the ones I use.
First I consider a sheet cake any cake that is only 2". I do not torte these, if they want filling they need to order a 4" cake.
1/4 = 9x12
1/2 = 12x18
Full = 18x24
HTH, but if a customer ask for a sheet cake (1/4, 1/2 or full) the first thing I ask is "How many people do you want to serve?" Most people have no idea what sizes these usually are they just use the jargon.

If you trace back the origin of the terms 'quarter, half & full' sheet cakes you will find a *true*
1/4 = 12x8x1 1/2"
1/2 = 12"x16"x1 1/2"
full - 24"x16"x 1 1/2"
They were based on the pans the old bakery already had on hand. As families grew smaller, they started cutting the cakes in 1/2; then in 1/2 again.
I always ask how many servings they need. I've had people call wanting a full sheet when they only need 10 -12 servings

This is from article from over a year ago I keep on file
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 16â by 24â 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 âlarge quarterâ 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 âlarge halfâ 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 âlarge halfâ board (14 x 20) and box (14.5 x 20.5), you will have to use full sheet boards and boxes.

Here's what I use:
1/4 sheet 7x11x2
1/3 sheet 9x13x2
half sheet 11x15x2
3/4 sheet 12x18x2
Full sheet (2) 11x15x2 side by side
Extra large sheet (2) 12x18x2 side by side
And I get $25.00 for a quater sheet cake

Totally agree with these two posts. I NEVER used the terms "half" or "full" because people have no idea what they're talking about. Don't get hung up on lables.....just find out how many people they need to serve and go from there.

what are the standard servings size for 1/4, 1/3, 1/2 & full?

yes great chart for two layer 'sheets'
industry standard for one layer sheets are
quarter 20-25
half-48-50
full- 98-100
it's a fraction of 100 servings--a fraction of a full sheet
so
a third is 32
three quarters is 75
give or take
wilton introduced cake pans that would fit in home ovens
full sheets didn't fit so they accomodated home bakers with the sizes they could sell

makes sense, although I have a 36" stove so its no worry for me :D
