The table below gives a rough guide to the number of portions you can cut from square or round cakes of various sizes.

Rich fruit cakes are traditionally cut into pieces measuring 1 inch x 1 inch, whilst sponge cake portions are usually larger, about 2 inch x 1inch.  This means a sponge cake cuts into fewer portions than a similar sized fruit cake ~ the first two columns in the table below below show number of portions for a fruit cake, and the last two are for sponge cakes.

Shapes such as ovals, hearts and hexagons will give roughly the same number of portions as a round cake of the same size.  Bear in mind that square cakes are easier to cut into rows of neat and tidy portions than round cakes!  See our tips on cutting fruit cake.
