I am doing a wedding cake and I was wounding what size to use for it it for 90 people I was thinking a 12 10 8 for a two inches between each layer what is the recommended space that would look good
I personally prefer 3 or 4 inches difference between each tier, but what you really need to do is find a cake serving chart (there's one on the Wilton site) to see how many servings each size tier will give you. Then you can go on to decide what sizes you want to use.
Oh you don't want an 8" for a top tier....that would look super squatty. 6-9-12 would be perfect. Serves 95ish.
