Frequently Asked Questions

What size cake fits a 16 inch 12mm drum board?

Use the 2 inch overhang rule. A 16 inch round 12mm drum board suits a 14 inch round cake (35.6cm), leaving about 1 inch (2.5cm) visible around the edge for decoration and safe handling. For multi-tier builds, use 3-5mm masonite under each tier and finish with this 12mm drum as the bottom base. Need icing quantities? Check our icing & fondant coverage chart.

Masonite vs 12mm drum boards - what's the difference?

Standard masonite boards are 3-5mm thick and ideal under each tier for stacking with dowels. 12mm drum boards are double-wrapped, extra thick (12mm) and designed as the final base board - they carry the weight of the entire cake without bending. Use both: thin masonite between tiers, 12mm drum on the bottom. Browse the full cake boards collection.
