A well-sized cake topper brings the whole design together. Start with the cake you plan to decorate, then choose the print that fits your layout.
Measure the top of your cake
For a round cake, measure straight across the top through the centre. Think about the area available for the topper rather than the size of the cake board. Leave room for any piping, candles or other decorations you want around the edge.
Happy Party offers round topper options including 16.5 cm and 19 cm on selected designs. Check the choices on the individual product page before adding an item to your cart. The product options also show the available material and price.
Choose a format for your celebration
A single round design creates a focal point on a birthday cake. Cupcake toppers work well when you want to repeat a theme across individual treats. An A4 format gives you another shape to consider for a larger design or a rectangular layout.
Plan space for the personal details
A short message and a clear central picture are easier to arrange than lots of small details. Decide which name, age or photo matters most, and give it enough room in the design. Compare the topper dimensions with your cake before making your final selection.
