These tables should be used as a guide only as what some would consider a good sized portion of cake others might consider either too large or too small. The chart below shows standard cake sizes however I am able to provide cakes in different shapes for example 3D shapes. (Cars, Dolls, Bears etc..)
Please contact me for consultation in order to provide you with exactly what you are looking for.
I believe it is best to overestimate the number of portions needed so that there are no disappointments.
