As a baker, creating an exquisite cake brings great a sense of accomplishment. However, choosing the right-sized cake boards and boxes for your cake is very important as well.
A poorly sized cake board will make bad effect: a cake board that’s too small will make the cake look bulky and cramped, while one that’s too large will leave the cake looking plain and empty. The importance of cake box size is even more critical—an incorrect size may stop the cake from fitting inside, it is too small for the board into the box,or even damage the cake. And it is clear to see that it is essential for us to choose the correct size of the cake boards and cake boxes for the cakes.
However, How to Choose the Right Size --for the boards and boxes?
Below is a guide to help you pick the right sizes for cake boards and boxes.
1. Cake Board Sizes
The size of the cake board is decided by the cake’s shape and sizes. A general rule is to choose a board that is 2 inches (about 5 cm) larger than the cake on all sides. This ensures proper support while keeping the overall look elegant.
l Round Cakes:
For a 6’’ round cake, suggest using an 8’’ board(20 cm);
For an 8’’ round cake, suggest using a 10’’ board(25 cm) ;
For a 10’’ round cake, suggest using a 12’’ board(30 cm) ;
For a 12’’ round cake, suggest using a 14’’ board (35 cm).
l Square Cakes:
For a 6*6’’ square cake, suggest using an 8*8’’board (20*20 cm);
For an 8*8’’ square cake,suggest using a 10*10’’ board(25*25 cm);
For a 10*10’’ square cake, suggest using a 12*12’’ board (30*30 cm);
For a 12*12’’ square cake, suggest using a 14*14’’ board (35*35 cm).
For a Quarter Sheet cake (9*13’’), use a 10*14’’rectangle board (25*35 cm) ;
For a Half Sheet cake (12*18’’), use a 14*19-inch rectangle board(30*45 cm) ;
For a Full Sheet cake (17*24’’), use an 18*25.5’’ rectangular board(45*65 cm) .
2. Cake Box Sizes
Cake boxes need to fit the cake board (with the cake on top) smoothly, and there are two key points to consider:
Width and Length: The box should be 0.5–1 inch (about 1.27–2.54 mm) larger than the cake board on all sides. This small gap is very important, it makes the cake easy to place the cake board into the box and take out, and keep good looking, safe delivery etc.
Height: The box height must match the cake’s height, including any decorations(cake toppers/ candles etc) on top.
For the single-layer cake,you should choose a box which is 4–6 inch height—note that if the cake itself is not tall but it comes with the tall decorations (like cake toppers), you still need a taller box, which is better.
For the double-layer cake,you should choose an 8–10 inch height box;
for the 3-layer cake,you should choose a 10–14 inch tall box. This ensures the cake fits perfectly without being squeezed, and if you want taller box, it is also available.
3. How to choose the material for the box
The material of cake boards and boxes should be chosen based on the cake’s size and weight to ensure it can support the cake stable.
For a regular single-layer cake, you can use a standard white cardboard (350gsm or 400gsm white /kraft paper are available)
cake board and a standard white cardboard cake box (around 4 inches tall), which is sufficient for basic needs.
For a double-layer cake or a heavier cake, we have to choose the thicker,stronger board or box to hold. Cake board—such as a 3mm double grey cake board, 3mm MDF board, or 12mm corrugated cake drum. For the box, choose a sturdy material like corrugated cardboard or thick plastic, which is both aesthetically pleasing and capable of bearing weight.
