Cake Portion Calculations and pricing

I was just wondering what depth of cake our the portion calculations and price guides for?



Hello Antonia

The portion numbers are based on the surface area of the cake. The depth of portion is entirely down to choice/preference. However, if you had a double barrelled cake say 2x 3" depth, they could be separated to give 2x 3" depth cakes or 1x 6" cake depth. 3" depth is usually plenty, but it just comes down to choice.


Hi Antonia

Below the cake portion calculator is information regarding the depth of cake. See information here:

The calculator does not give price guide for each portion. For pricing information please watch David’s very comprehensive blogs here:
