A 3 tier cake serves about 80 portions comfortably, and is usually the perfect size for a wedding of 80-100 guests if you’re serving cake in the evening. At Caked, my standard tiers are made up of 4 layers of sponge, so they’re extra tall. Therefore portions can be cut smaller if needed.
How big of a cake do I need for 70 people?
How many cakes do I need for 100 guests?
How much is a wedding cake for 75 guests?
A common calculation for wedding cake allows for one slice of bride’s cake per guest and a half slice of groom’s cake. So if you have 100 guests, you’d need 100 servings of bride’s cake and 50 servings of groom’s cake.
