This cake box is 7 inches tall, made from thick, corrugated cardboard and has a bleached white outside and kraft inside We recommend that you choose a cake box that is at least one size larger than your cake. For example, if your cake is an 14 inch cake, you'll want to use a 16 inch or 18 inch box depending on how much extra room you need for decorations. You'll want to choose a cake board or drum that is the same size as your box so that your cake doesn't slide around inside the box.
