Bakery & Dessert Trays
Round Cake Boards
- Standard and custom diameters
- Foil or plain finish
- Thickness to cake weight
A cake board is a structural component pretending to be a presentation item. It carries the entire weight of a cake through decoration, transport and cutting, and if it flexes at any point during that the icing cracks.
Round is the majority format, because most celebration cakes are round and most cake tins are too. The two decisions that matter are diameter and thickness, and they are related.
- Cut to standard diameters or to your own tin sizes
- Thin boards for single tiers, drums for stacked and heavy cakes
- Silver, gold and plain finishes
- Thickness specified against cake weight and diameter
Pricing starts from $0.30 per tray
The unit price depends on the size, board, printing, finishing, quantity and delivery country, so every quote is worked out for your specification rather than taken from a list.

03 — In detail
Diameter: match the tin, then add
The board should be larger than the cake, and how much larger is a presentation decision. Flush with the cake looks like a mistake. About half an inch of border reads as neat. An inch or more gives room for a piped border and a ribbon, and is the convention for decorated celebration cakes.
Start from the tin diameter you actually bake in, decide the border you want, and order to that. A board that is a size out means either a visible rim of exposed board or a cake overhanging its own base, and neither can be fixed after decorating.
Thickness by cake
Flex is the enemy. As diameter goes up, the same thickness gets proportionally weaker, so a large cake needs a disproportionately thicker board.
| Cake | Board type | Why |
|---|---|---|
| Single sponge up to 8in | Thin board | Light enough that a thin board will not flex noticeably |
| Single cake 10–12in | Thicker board or thin drum | Span increases; a thin board starts to bow when lifted |
| Fruit or mud cake, any size | Drum | Dense cakes are far heavier than sponges of the same size |
| Base tier of a stacked cake | Drum, full thickness | Carrying the whole stack, plus dowels and handling |
| Upper tiers of a stacked cake | Thin board | Only carries its own tier; a drum adds unnecessary height |
Practical points
- Store boards flat and dry — a board that has picked up moisture will bow before you put a cake on it.
- For a stacked cake, the base drum and the upper thin boards are different products; buy both.
- A wrapped edge hides the board core and looks noticeably better on a photographed cake.
- If the cake sits directly on the board, ask for a food-contact-appropriate surface rather than assuming.
- Foiled finishes mark if slid across a surface — handle them by the edges.
Buying for a wedding or a large stacked cake? Tell us the finished weight and the number of tiers, not just the base diameter. The base drum on a heavy multi-tier cake is a genuinely structural component and it is the wrong place to save a few cents.

Round Cake Board questions
How much bigger than the cake should the board be?
About half an inch of border for a neat, plain finish, and an inch or more if you are piping a border or adding a ribbon. Flush with the cake reads as a mistake rather than a style choice.
What is the difference between a board and a drum?
Thickness. A thin board suits a light single cake and the upper tiers of a stacked cake. A drum is much thicker and is what carries a heavy fruit cake or the base tier of a stack. Using a board where a drum is needed is the most common cause of cracked icing.
Will the board bow under a heavy cake?
If it is too thin for the diameter and the weight, yes. Flex increases sharply with span, so a large cake needs a disproportionately thicker board. Tell us the finished cake weight and diameter and we will specify it.
Can I get boards cut to a non-standard diameter?
Yes. Standard sizes exist because tins are standard, but if you bake in an unusual size we cut boards to it. Send the tin diameter and the border you want.
Are cake boards food safe?
Where specified for direct food contact, yes, and we confirm that in writing. Many bakers use a thin barrier between a rich cake and the board regardless, which is a reasonable belt-and-braces approach for a long-life cake.
Can the board be printed?
The underside can be printed freely. The top face is usually under the cake, so printing there is largely wasted — a printed border outside the cake footprint is the practical route if you want branding visible.
Why do my boards arrive slightly bowed?
Board absorbs moisture from the air. Stored flat in a dry place they stay flat; stored on edge in a damp room they curl. If boards arrive bowed, it is usually a storage or transit humidity issue and it is worth telling us so we can adjust the packing.
Which finish should I choose?
Silver is the traditional default and disappears under a decorated cake. Gold reads as more formal and suits celebration work. Plain white or kraft suits contemporary naked cakes where the board is meant to be visible.
Do you supply square boards too?
Yes — see the square cake board, which has different structural considerations because of how the corners behave under load.
