I have never done a square wedding cke before (only done 5) wedding cakes and they weren't large ones. I have an order for a wedding cake-serves 150-she wants them square-4 layers stacked on top of each other for the giftbox effect-what size pans do I use? I know there will be a minimal border on it as her mother will put silk flowers in the corner of each layer and on top so there but want to have some room too...please advise me! Thanks.

If serving the entire cake a 6", 8", 10", 12" will provide approximately 170 wedding size servings. If the bride and groom will be saving the 6" cake that would be perfect leaving approximately 150 servings for the reception.

Hope this helps!

Or you can go with 5. 6, 10 and 14 - which serves about 166 if you plan on saving the top layer. This is the 3 inch high layers. Personally I prefer the 4 inch increments in size for a stacked cake, mainly because they seem to be more stable, less tippy.
