Cake Sizing

Once you have decided what style of cake you want. You must figure out how many servings you require. Things you should take into account are:

  • How many guests are in attendance?
  • How is the food being served (buffet/sit down)?
  • Are you serving other desserts?
  • Are you serving the cake at a luncheon or after a banquet?
  • Do your guests typically have a sweet tooth?
  • How large of a slice do you want to serve?
  • A good way to estimate the size of cake you need is:

    Take the required number of servings and multiply by the size of slices you want (in square cm – or inches).

    This will give you the overall total surface area of the cake you require.

    Once you know how much cake you need in total, consider how many tiers you would like and find the sizing for each tier that would make a proportional looking cake.

    For instance have the tiers step up in constant increments (ie: 6 – 9 -12 where each tier widens by 3 inches or 8 – 11 – 14, NOT 6 – 8 -16 unless that is the look you are trying to achieve). As an aid, below are the typical servings produced by each size of round cake.

    6 28 14 9 7
    7 38 19 12 9
    8 50 25 18 12

    Typical sizes would be

    Two Tier 6-10 6-11 6-12 8-12
    Three Tier 6-9-12 6-10-14 8-11-14 8-12-16
    Four Tier 6-8-10-12 6-9-12-16 8-10-12-14
    Five Tier 6-7-8-10-12 6-8-10-12-14 8-10-12-14-16

    As mentioned earlier, you can augment your cake configuration with a Groom’s cake. This is highly recommended for receptions of over 200 to 300. The Groom’s cake serves 2 purposes. First, it reduces the overall cost of providing cake to all of you guests. Second, It gives the caterers a chance to start cutting cake up in advance to serve your guests. Cutting 300 slices can take up to 25 minutes. By cutting the Groom’s cake first, it also gives the Bride’s cake more stand time in the reception area for display. Grooms cakes can be made in any size as to complement your needs as required. Some cultures and protocol actually use only a Groom’s Cake with no Bride’s Cake.
