Ok so ive been asked to do a wedding cake for December, im fine with decorating cakes etc just not good with working out sizes. She wants 3 tiers, round and for it to feed 120 people, one fruit cake and 2 sponge. Could someone tell me what size cakes would suite this number and would look right size wise.

Thanks, Sarah

(also, dense fruitcake serving sizes can typically be smaller.)
