Can your pro's out there tell me what size of pans to use to replicate this cake. Initially I thought 12'' 10'' 8''6'' but I don't know if they are just two inches apart then will there be enough of a ledge for the candle holders? I just can't see it being 6, 10, 14, 18 but maybe it is... what do you all think please!!!

I think they are 6,10,14,18

I would guess 6, 9, 12, 15? That bottom layer tier does look pretty big!

To know for sure you would need a point of reference.
If the frame in the background is an 8x10 then the cakes could be 4,8,12,16???

Ok, the numbers geek here actually got a measuring tool and did a "to scale" comparison.

I'm assuming the silver stand is an 18". The top tier looks like a 6". Based on those measurements, I think it's 6/8/12/14.

I am with indydeb....

But doesn't the top tier seem to be 1/2 as big as the next? That's why I thought 4 for the smallest. Hmmm ...Watson?

I agree that indydeb is probably right in her measurements. I just don't know how I will get the candle holders to sit on a 1 inch ledge? Any thoughts?
