Hi! This cake that I will attach below...is from some other wonderful talented cake decorator and my bride once her cake spiraled like that and square but with pillars in between so they can put the gerber daisies there. There is going to be between 200-230 people eating the cake. I cant figure out what tier sizes are on this cake...so I guess my first question is if you could figure out probably what size each tier is and second question is...what tier sizes should I go with for a square cake to feed 200-230 people?

thanks for your help!

Earlene has a great serving size chart, for numerous shaped pans.

It looks like a 6,8,10 and 12 but I don't know if that would feed 230.

Earlene's chart is a good starting point.

I have done quite a few of these cakes, and I believe that the sizes are: 6,10,14,18. You have to have the 4inch difference to get them to not hang off the edge. With that said, Wiltons chart says that a 6 serves 18, 10 serves 50, 14 serves 98, and the 18 serves 162 total servings of 328...or you could do a 4 (? servings), 8 (32 servings), 12 (72 servings), and 16 (128 servings) for a total of 236.
I hope this helps

what was that exactly about a 4 inch difference so the sides dont hang off? I didnt quite get that...

n/m i get what you meant now...but I am using pillars and so would I still need a 4 inch difference? since each tier will not be on top of eachother but on pillars/plate? also...can pillars/plate hold a square 12 or 14 inch with more on top? I havent tried it yet!

aprilcake, are you going to set them up on pillars perfectly straight or slightly askew, like in the pic?

An 8" cake, when measured corner to corner, is over 11" wide, so setting it askew on top of a 10" cake will cause overhang.

yes she wants each tier too be off set like the pic attached. Just on pillars...so your saying I will need the tiers to be 4 inches apart?
