Frequently Asked Questions

When should I use a 4mm masonite board instead of a standard 3mm board?

A 4mm board is recommended for cakes larger than 16 inches, very heavy multi-tier constructions, or any cake that needs extra rigidity during transport. The additional thickness reduces flex and minimises the risk of the board bending under a heavy load. For standard single-tier cakes up to 16 inches, a 3mm board is sufficient.

Can you stack cakes on masonite cake boards?

Yes — masonite boards are the standard choice for tiered cake construction. Place a 3mm masonite board beneath each tier, insert dowels into the tier below before stacking, and use a thick 12mm drum board as the base for your final display. The rigidity of masonite keeps each tier level and stable during decorating, transport, and presentation.
