Cake size and portions: serving ranges and practical cutting examples

Start with how you want to serve the cake. Its diameter alone cannot tell you how many satisfying slices it will provide.

To choose a cake size, tell us how many people will eat it and whether you want dessert portions or smaller slices alongside other food. A serving range describes different ways of cutting the cake. It does not promise that its largest number will provide generous dessert portions for everyone.

Compare the current serving options

These are the serving bands listed for selected cakes in our catalogue. The options refer to the individual product and design; they are not a universal chart for every cake with the same diameter. Check the product page and confirm the final size when ordering.

Listed serving options by cake
CakeServing bandsWhat to discuss with us
Medovik honey cake4–8, 12–20, 20+Standard rectangular cake or a custom size and design
Napoleon4–8, 12–20Pastry layers, intended portion size and finish
Kyiv cake4–8, 8–12, 12–20, 20+Meringue cake size and decoration
Chocolate Delicia4–8, 8–12, 12–20, 20+Sponge layers, height and custom design

See Medovik, Napoleon, Kyiv cake and Chocolate Delicia for their current options. Not every flavour offers every band.

What the standard dimensions tell you

The standard rectangular Medovik is approximately 14 × 21 cm and around 0.8 kg. The standard rectangular Napoleon is approximately 11 × 18 cm and around 1–1.1 kg. Different fillings and layers mean that a smaller footprint can still weigh more. Weight and width are useful details, but neither replaces a serving plan.

For an illustration, divide a 14 × 21 cm rectangle into two rows and four columns. That gives eight pieces with a footprint of about 7 × 5.25 cm each. Dividing the same rectangle into two rows and two columns gives four much larger pieces. The cake has not changed; the portion has. Confirm the dimensions of your actual order before using this cutting plan, particularly for a custom cake.

Three examples to help you order

  • Eight people having cake with tea: tell us whether you want eight modest slices or larger portions. Do not choose solely because “8” appears in a serving range.
  • Twelve people having cake as their only dessert: ask for 12 dessert portions. If you choose Medovik, discuss the listed 12–20 option and how it will be cut; there is no listed 8–12 band for this cake.
  • Twenty people at a buffet: explain that there are other desserts and say whether you want cake for everyone. If you also want leftovers, add those portions to the brief.

Share the cutting plan with the person serving

Agree the intended number of slices before the first cut. For a rectangular cake, marking the rows and columns lightly can help keep the portions even. Follow the supplied instructions for removing decorations and supports before serving.

For a wedding or venue celebration, ask who will cut the cake and pass on the agreed portion count. Our wedding flavour guide can help narrow the flavour choice before you send the guest count and design through our custom cake form.

These are the sorts of things Olga ends up explaining in messages before she confirms an order: what travels well, what complicates delivery, and what is better kept local.

Better for local delivery or collection

Start with Vanilla Delicia Birthday Cake

Vanilla Delicia Birthday Cake is the kind of cake Olga suggests when the order needs a proper celebration finish, local delivery, or collection rather than parcel-post packing.

Questions people ask before ordering

The practical details that matter first

These are the bits customers usually want answered before they commit: freshness, delivery timing, and whether a postal cake is the right fit at all.

How many people does an 8-inch cake serve?

The answer depends on the recipe, height, layers and slice size. Tell us the cake you want and the number of dessert or smaller buffet portions you need so we can confirm a suitable option.

Why does the same cake have a serving range?

A range allows for different portion sizes. Four large pieces and eight smaller pieces can come from the same rectangular cake. Explain how you plan to serve it before choosing a size.

Do all flavours come in the same serving bands?

No. For example, the current Medovik options include 4–8, 12–20 and 20+, while Kyiv and Chocolate Delicia also list an 8–12 option. Check the individual product and confirm your order with us.

More notes if you are still weighing it up

These are the pieces people usually read next when they are deciding what can go in the post, what should stay local, and how much fuss the delivery should involve.

Need the practical answer?

Choose the format that suits the journey

If the parcel has to go across the UK mainland, start with the cakes by post range for standard-design honey cake, honey cake slices, or caramel biscuits vacuum-packed for post. If the order depends on height, chilled fillings, or a detailed design brief, browse the custom cakes range for the celebration options that are better suited to local delivery, collection, or UK delivery by agreement.
