Cake size

We are serving our cake for dessert and I want lots to take home afterwards! We therefore have a lot of cake! If you were planning on serving it a while after the wedding breakfast, and you don’t want much leftover, then I think 50 servings is probably a reasonable estimate. Best person to ask would be a wedding planner or caterer, I suppose.

I would get one for every guest - you can always send people home with extra bits or give them to people who couldn't attend, but I wouldn't want to risk someone wanting cake and not being given any. Assuming 1/3 of your guests won't eat it seems a high number to me too.
