I need a cake for  130-150 people, I am doing a 3 cake display.  One cake will be a square 8 inch (almost 6 inches tall).  if the other cakes are 4 inches tall, are two, 12 inch cakes enough?

thanks!

so on the 6" tall cake -- if you put a board in it at the 3" mark you can get more servings if you want -- if it's all one cake then you get the same amount of servings as any other 4" tall cake because it goes by footprint -- each serving will be bigger than usual but no way around that unless, like i said you put in the extra board -- your choice --

another consideration is that that size serving doesn't fit well on the 6" cake/dessert plate

so if your 12's are round you will have approx 113 servings there -- then 32 on the 8" square for a total of 145

here -- play around with this lovely gadget:

or ask some more questions if i missed what you meant -- i'm having a lovely lazy day chilling and i should be back on here -- or someone will respond 

best to you

thank you! appreciate the help.
