Frequently Asked Questions

What size cake fits a 18 x 16 inch rectangle board?

Use the 2 inch overhang rule. A 18 x 16 inch (45.7 x 40.6cm) rectangle masonite board suits a 16 x 14 inch (40.6 x 35.6cm) rectangle cake, leaving about 1 inch (2.5cm) visible around each edge. Unsure how much icing you need? Check our icing & fondant coverage chart.

Masonite vs scalloped cake boards - what's the difference?

Masonite boards are 3-6mm thick compressed hardboard, rigid and designed to carry decorated cake weight without flexing. They are the go-to for stacking tiers with dowels and heavy sheet cakes. Scalloped boards are thinner decorative display boards with a wavy edge for single-tier presentation, not for stacking. Browse the full cake boards collection.
