I have a square wedding cake coming up soon and for some reason I have cob webs between the ears so I am turning to you guys. What size pans would you use for a 4 tier square cake for 120 people. They are not serving top tier. I've tried to figure it out and I am all over the place. Like I said cob webs have taken over this old brain! Help!!! TIA

Here's a link to Wilton's serving guide. This guide is for 2 layer - 2" deep cake pans. If you are using the 3" there is another serving guide link in the articles section. You may not get exact 120 servings so you'll have to let the bride decide. I would go with more and charge accordingly. It also depends on the size layout and if the bride likes the design (I personally like 3-4" difference but it totally depends on the design itself. Some of them look great with the 2" difference).

If you went with:
6, 8, 10, 12 the total number of servings you would (not including the 6" top tier) would be 154.


ETA: I wanted to add a pic so you could get an idea of the sizes together (In case you haven't done it yourself yet)

This is one of my fav's (it's 5 tier - 4/6/8/10/12)

If you went with a 4/6/8/10 you wouldn't have enough servings. The 6/8/10 would only give you 100 servings.
