Number cake: sizes, servings and formats
The number cake, that digit or letter-shaped cake piped with cream and topped with fruit, meringues and flowers, has become a favourite for milestone birthdays. Its main challenge is choosing the right size for your guest count. Here is how to count servings, which formats exist and what prices to expect.
What is a number cake?
The number cake (sometimes called a cream tart) is a cake made of two or three layers of biscuit cut into the shape of a digit or letter, generously piped with cream (mascarpone, whipped ganache, buttercream), then decorated with fresh fruit, macarons, meringues, edible flowers and gourmet touches.
Unlike a tall round layer cake, it is flat and spread out lengthwise. It is most often served to celebrate an age (a "30", a "40"), initials, a date or a short word. Its shape directly dictates the number of servings, which makes sizing essential when ordering. To compare with other formats, see our layer cake price guide.
How a number cake serving is counted
A number cake is cut differently from a round cake. The digit is sliced across its width into regular slices following its shape. The number of servings therefore depends on the developed length of the digit and the size of the template, not just its visible surface.
A few useful benchmarks:
- Full digits like 8 or 0 offer more cake, and therefore more servings, than thin digits like 1 or 7.
- A number cake serving is richer than a slice of classic sponge: the cream and fruit fill you up quickly, so you can plan slightly smaller portions.
- For a two-character figure (a "25", a "40"), you add up the servings of both templates.
The baker or cake designer adjusts the template to your guest count. Tell them that number from the start via messaging so they can size it correctly.
Sizes and servings by guest count
Here are indicative figures for a single digit (one character). The number of servings varies with the template format and the exact shape of the digit.
| Digit format | Servings | For how many guests |
|---|---|---|
| Small (about 20 cm) | 6 to 8 | Small gathering, family meal |
| Medium (about 30 cm) | 10 to 14 | Classic birthday |
| Large (about 40 cm) | 15 to 20 | Extended party |
| Extra large (45 cm and up) | 20 to 30 | Large event |
For a two-character figure, add the values of both templates: a medium "30" thus serves about 20 to 28 people. If in doubt, choose the next size up: a slightly generous number cake keeps better than one that is too tight.
Number and letter formats
The number cake comes in several configurations, each affecting servings and price:
- A single digit ("5", "9") for a one-character age or a date.
- Two digits ("18", "50") for most adult birthdays; this is the most requested format.
- One or more letters (an "M", initials, a short first name) for a christening, wedding or a statement.
- A short word ("LOVE", "THANKS") for a special occasion; each letter counts as an additional template.
The more characters there are, the more time goes into cutting, filling and decorating. A four-letter word requires four times the work of a single digit, which shows in the price. Discover creations and find a professional near you on the catalogue.
Indicative price ranges
In France, a custom number cake usually costs between 3.50 and 6 € per serving, with careful decoration and fresh fruit explaining the gap with a standard cake. Some benchmarks:
| Configuration | Servings | Price range |
|---|---|---|
| One digit, small format | 6 to 8 | 30 to 55 € |
| One digit, medium format | 10 to 14 | 45 to 85 € |
| Two digits, medium format | 20 to 28 | 90 to 160 € |
| Two digits, large format | 30 to 40 | 150 to 250 € |
These ranges generally include baking and elaborate decoration. A very loaded design (lots of edible flowers, homemade macarons, several flavours) pushes towards the top. For a full breakdown, see the number cake price guide.
What makes size and price vary
Beyond the number of characters, several elements affect sizing and the final price:
- Thickness: two layers of biscuit or three; three layers give taller, more filling servings.
- Decoration density: a digit covered in fruit and meringues feeds more than a minimalist one.
- Flavours and filling: mascarpone cream, ganache, fruit insert, each option has its cost.
- Dietary constraints: gluten-free, dairy-free or vegan require dedicated recipes; report your allergies via messaging.
- Season: out-of-season fresh fruit raises the cost of the decoration.
Choosing the right size and ordering with confidence
To aim right, count about one serving per guest for a dessert after a meal, with a 10 to 15 % margin for the hungry ones. If the number cake is the only treat at a snack or sweet aperitif, plan more generously. Share an inspiration photo and the exact guest count with the professional: they adapt the template and offer a reliable quote.

Frequently asked questions
How many people does a two-digit number cake feed?
In medium format, a two-character figure serves about 20 to 28 people. In large format, you reach 30 or 40 servings. Always add the servings of both templates.
Does the 1 make fewer servings than the 8?
Yes. Thin digits like 1 or 7 offer less cake to cut than full digits like 0 or 8. At equal format, they give slightly fewer servings.
Which size for a birthday of 15 people?
A single digit in large format (about 40 cm) covers 15 to 20 servings, which works. For a two-character figure, a medium format is more than enough.
Can you make letters or a first name?
Yes, the number cake comes in letters, initials or a short word. Each letter counts as a template, so the more characters, the more servings and the higher the price.
How much does a number cake cost on average?
Usually between 3.50 and 6 € per serving. A medium-format digit comes to 45 to 85 €, an elaborate two-digit to 90 to 160 € depending on the decoration.
How do I order without risk?
Look at the maker’s portfolio and reviews, chat via messaging to settle the size and report your allergies, and benefit from escrow payment that only releases funds after good receipt.
