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.
| Cake diameter | Topper width |
|---|---|
| 6 inch | 3–4.5 inch |
| 8 inch | 4–6 inch |
| 10 inch | 5–7.5 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
- Keep one clear focal point: if the cake is already heavily decorated, use a simple topper.
- Pick a topper colour that contrasts with the icing so it stands out in photos.
- For party orders, buy a few extra, since customers often ask for a second cake at short notice.
