Ok, important question now lol

Wedding cake. I am having 3 tiers, sqaure (there is a pic on my profile)

How high is each tier supposed to be? The cake tins I have are 3 inches deep and I think 3 inches high is too small and suggested to the cake lady that they should be bigger. Does anyone know what the normal height is?

Mine stood about 27cm high in total, im guessing thats 3 inch on each teir and added height with icing.... i was rather happy with my size but it did look smaller then others i have seen x x

I think it really depends which design of cake you go for in regards to how big the tiers should be. I would say a decent size is 4-5 inches for the actually cake and then the icing will bulk it out a little more x x x
