How to Choose the Right Cake Topper Size

5 November 2026 · 3 min read

A topper that is too small disappears on the cake. One that is too big looks top-heavy and can lean. Use these simple proportions to get it right.

The half-to-three-quarters rule

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

6 inch3–4.5 inch
8 inch4–6 inch
10 inch5–7.5 inch

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

Check the stick, not just the topper

A topper's stick needs to go deep enough to stay upright. For a soft or tall cake, push it into a cake board or a firm layer rather than only into the top sponge. Shorter sticks suit small cakes and cupcakes.

Match the topper to the occasion and the colours
