I need a cake to serve 75 people. If I do a 6", 8" and 10 inch, that only serves 53... How can I bump up the servings, to reach my target guest amounts, without making another cake? I would prefer to have the increments spaced out a little, as it will have lots of props on it...
TIA

According to the Wilton wedding serving chart those size cakes will feed approx. 74 and that is the standard 1x2x4 inch slices. You could go for slightly bigger slices which would yield you approx. 60 servings. Links below HTH

thank you! I don't know where I got my charts from, but they were obviously way off! Thank you!!
