4 tier wedding cake for 140 - advice please!

[Nocoffeenoworkee]

So I've agreed to make my friend's wedding cake - I've got my expert baker mum on board so I'm feeling pretty darned confident. The only thing we're short on is quantities for 140 spread over 4 tiers.

Would 12", 9", 6", 4" do it?

Ta!

i did 12" 8" 6" recently and that fed 140 comfortably my friend also had fruit and ice crean to acompany it just incase i made all the cakes quite deep once they were filled they were over 5" deep

Is it fruit cake ? And is it as dessert, or in addition ?

I will check quantities with my cake decorating book which tells you all of the permuatations

It's fruit on the bottom, then chocolate sponge, then lemon sponge and orange sponge on top.

Having spoken to a local cake specialist I was advised to go for 12", 10", 8" and 6". Methinks this will be a large cake and will feed more than 140!

Thanks for your help
