Hello,
 

I have a question for you all. I have a customer requesting a 5 Tier Multi Shaped Wedding Cake for 250 people in Round and Square shaped.

Bottom tier - will be round shape
2nd Tier ---- will be square shape
3rd Tier ---- round shape
4th Tier ---- square shape
5th Tier----- round shape

I'm not sure what size of pans they are, can anyone please help???

Many thanks!!!! 

just a quick calculation here--must be checked & re-checked for accuracy so what i got is

18r  x 12sq  x 11r  x 7sq x 6r = 285

17r x 11sq x 10r x 6 sq x 5r = 240

17r x 11 sq x 11 r x 7sq x 6r = 272

so actually

18r x 12sq x 10r x 6 sq x 5r is agh 264

my suggestion to you is make all these sizes cut out of paper and stack 'em up and see what you like

you have to be careful because neither a 16" nor a 14" square fits on an 18" round--you got the corners hanging off-rookie mistake there -- the correct round to square proportions are in my suggestions-- if i din typo anything up there ;) --you could get a 13"sq on an 18"rd --the corners would be right flush with the 18

but conversely you can put a 12" r on top of a 12" square--you need to decorate it right to make it happen--but you can do it so there is wiggle room but you wanna stack it up to see how it flows with your design etc.--for example a beautiful damask design--even white on white would be stunner on the flush areas on a 12rd atop a 12 sq~~whatever

so you wanna make sure everything is proportional to your design

and these are for 4" tall tiers

*** these are just rough calculations--do not rely 100% on my not making a mistake--

if i was doing this cake i would redo my figures several times--this is rough draft starting point for you

odd numbered pan serving estimate:

7" sq = 25

9" sq =41

11" sq = 61

13" sq = 85

15" sq= 113

7" rd = 18

9" rd = 32

11" rd = 47

13" rd = 66

15" rd = 88

17" rd = 113

give or take a few ;)

I love this website also for inputting different pan sizes to get servings:

Oopsie...thanks!!

here are the right angle measurements for squares:
4" 5.66
5" 7.07
6" 8.49
7" 9.9
8" 11.31
9" 12.73
10" 14.14
11" 15.56
12" 16.97
13" 18.38
14" 19.8
15" 21.21
16" 22.63
17" 24.04
18" 25.46

so technically, a 13" sq on an 18" rd would hang over .38 (everything else appears accurate).

Thank you for your response much appreciated! That's a great idea about cutting out the sizes I should of thought of that first! The client wants it smaller than 18" starting point so will have to cut out my shapes and see what gels I suppose 

Thanks again 

Alex31, Do you keep Dummies around.  They can also hep give your client an idea of the cake shape will look like?  Just a thought.
