Hi, I tried searching to find these answers but had no luck. Could someone please explain the sheet cake sizes? Is a 1/2sheet cake 12x18? Is a full sheet cake 18x24? The wilton party size says the 12x18 should serve 72, is this right? thanks!

I have heard different things but this was what I found.

9x13 is quarter sheet
18x24 is half

When I first started doing cakes (before I ever heard of CC) I found these commercial sizes on another cake site. They work well for me.

Commercial Sizes

Full sheet:26x18 - serves 60-96
Half sheet: 18x13 - serves 30-48
Quarter sheet: 13x9 - serves 12-20

(ETA serving info)

The history of sheet sizes:

A commercial bakery's largest baking pan is usually 18x24 (or 18x26). This is the full sheet.

Cut the sheet in half and it's 12x18 .... half sheet.

Cut the sheet in quarters and it's 9x12 or 9x13 .... quarter sheet.

Do the math and it's pretty logical and easy to remember.

However, that said, I REFUSE to use the terms "half" or "full" because of this very discussion. Too many people throwing the terms around and they've NO IDEA what the size is. I'm tired of cake civilians ordering a "full" sheet cake and then when I tell them it's $150, they act shocked and say, "FOR ONLY 20 PEOPLE???????"

Hey, dumba$$, you didnt' order cake for 20 people..... you asked for a freakin' FULL sheet cake, so that's what I quoted ya! If you dont' know what you're ordering, then stop pretending to be one of the cool kids by throwing around terms when you don't know what it means!

I agree completely. I always ask how many servings they are looking for and if there are going to be other desserts served.

You can cut a 12x18 6x6 and get 36; you can also cut it 6x8 and get 48.
A full sheet is two 12x18s put together; so using the first scenario only doubled for two cakes; that's how they are getting 72 servings. But you can also get 96 servings cutting it the second way.
