Let's tackle the big questions....
*Please remember that the info below is intended as a guide*
The cost of your cake will be determined not only by the size, but also by the flavour you choose, any special dietary requirements, and most notably by the complexity of the design.
When it comes to portions.... it depends how big you cut the slices!
Basic portion guide
My standard cakes have four-layers of sponge inside. The smaller of these two numbers assumes a full 'dessert portion', where each slice is the full height of the cake. Expect a full tummy!
The larger number is a dainty, taster portions (or portions for kids), where you cut each vertical slice into two. This is best when you're eating the cake alongside other desserts or lots of other party food. This is also considered a wedding portion size.
5"/13cm 8-16 portions
6"/15cm 12-24 portions
7"/18cm 16-32 portions
8"/20cm 20-40 portions
9"/23cm 28-56 portions
If your cake has three layers of sponge rather than four, assume the lower number to be safe.
