I've been baking layered cakes for years.  And now I want to start doing sheet cakes because my customers are asking.  For a full sheet cake using 2 12x18 pans, how many will it feed?

A full sheet serves 96 and a half sheet 48.  This is provided they are cut in 2x2 size pieces which is standard.

a 12" x 18" half sheet serves 54, so two of them serves 108.

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 servingsicon_sad.gif

This debate has been going on since the internet came into being! :)  Please consider my post above ^^^

If you google "size of full, half, and quarter sheet cake" you will find many,many posts with different replies.  But....trace it back to it's origin and what I posted above is the true  information.

More information:   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   Read more at http://www.cakecentral.com/forum/t/562714/is-9-x-13-a-14-sheet-cake-how-big-is-12-sheet-cake#5Cy2YZ0tGBMDhgPF.99


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.
