Most customers don’t know what the cake sizes are like and when I ask customers what size of cake they require, the majority of people reply, “I don’t know!”
The actual size of cake required depends on several factors:

  • Number of people you’re serving
  • The type of cake you’re cutting  ( you get less slices with sponge cakes).
  • If you want standard slice sizes or something more generous

Below is a rough guide to helping you decide on the size of cake you require.
