The Baker's Guide

Quick answers for home bakers and bakeries: what size box, what size topper, and where to buy in bulk.

Which cake box for which cake?

A box that is about 2 inches wider than the cake lets you slide it in without smudging the sides. Add height for tall or topper-heavy cakes.

Cake size (round)Box widthBox height
6 inch8 inch5 inch (6 inch with a tall topper)
7–8 inch (about 1 kg)10 inch5–6 inch
9–10 inch12 inch6 inch
Two-tier or tall cake2 inch more than the widest tier8 inch or more

Rule of thumb only. Cake weight per inch varies with the recipe, so measure your own cake.

How big a cake topper?

For a balanced look, a topper's width is usually half to three-quarters of the cake's diameter. Go to the smaller end for toppers with tall figures or sticks, and the larger end for flat, wide designs.

Rule of thumb only. Check the size in each product's description.
