Since there are 4 inches between the first and second tier and only 2 inches between the 2nd and 3rd tier? I need to serve 110.
Will there be a topper?
Personally I think it will look squatty with a top tier that big. Are you stuck on a three tiered design? That will feed a bit more than 110 people too... 130-140 would be more like it.
A 6-9-12 will serve 100 and you can always do another 6" kitchen cake to have out back to make up the servings.
I kind of thought it would look squaty too. The serving guides I went by said that would feed 110. It is going to be just plain buttercream with gold ribbon around the bottom of each tier. They are going to put red roses on the top and down the sides.
According to Wilton a 6, 10, 14 will serve 116. The size differences would be the same between each tier that way. But I think the 8, 10, 14 would probably look fine too. I did a google search to try to find some pics of an 8, 10, 14 to give you an idea of how it would look.
If you take of the top tier of this pic it would be an 8, 10, 14 (scroll down a little bit)-- http://www.weddingcakes.dragonflydesserts.com/Flavors.html
This one is also an 8, 10, 14-- http://www.karenscakeshoppe.com/ShelleeSm.jpg
I think that combination will look fine.
It would be fine so long as they are putting something on top. A naked 8" top tier is a bit big, though not horribly so. If they are going to have roses they will take up the negative visual space and it won't seem as big.
My favorite size for a top tier is 5" though. I'm not a fan of big top tiers at all, but that's just my style/opinion.
Why not go for 8, 11 & 14 that way you will have even tiers
It will look like this (minus the very top)
I think I am going to do 14, 10, 6. That way there are 4 inches between each so its atleast even and I will still get the 110 servings I need.
I'd do a 7-10-13 for 115 servings (by my chart), but if you don't have the odd sized pans that could be a pain.
