Hi There!
Has anyone made a three tiered stacked cake with the dimensions 16", 12", 8"...
Does anyone have pictures of what that would look like?
Would those dimensions look a little off for a wedding cake because of the 4" sizing differences between each level?
Thanks in advance for your help.

I dont think it would look strange but it would be a very large cake.

4" difference is not odd ... it is pretty standard. The only thing that "may" look odd is the 8" as the top tier ... may look big to some (although when I first started doing cakes 30 years ago, an 8" top tier was the norm. It's only in recent years that it's gone to a 6" top).

Why would you think they would look off? I actually like a 4in difference over 2in in most designs because it gives you more of an edge around the cake.

I think it would look nice. I like at least three inch difference between tiers. I use 12 inch and 8 inch tiers all the time.

Thank you Everybody.
I am doing my first wedding cake, and the bride wants 3 tiers. (and it needs to serve 120-140) That's why it is going to be so large.
Thanks for all of your great input and kind comments.

Here's one I did. Not sure if your talking round or square?

Thank you malene541!
That's beautiful.
I forgot to mention it needs to be round. But yours gives me a much better idea. (I am terrible at visualizing these things, I do much better with an example.) Thank you again.
