How big should a cake topper be?

Almost every disappointing topper is the right design at the wrong size. The measurements below are the ones that survive contact with an actual cake.

A cake topper should be 60 to 75% of the cake diameter in width, and should stand 5 to 8 cm above the surface of the cake. On a 20 cm (8 inch) cake that means a topper roughly 13 to 15 cm wide. Wider than the cake and it looks like signage; narrower than half and it disappears in photographs.

Width by cake size

Skewer length is the total stick, including the part inside the cake. Allow 4 to 5 cm of it to be buried.

The upper end of each range suits a plain cake, where the topper is doing all the decorative work. The lower end suits a cake that already has drip, sprinkles or flowers, where the topper is one element among several.

Height is the measurement people forget

Width gets all the attention because it is the number printed on the template. Height is what decides whether the topper reads in a photograph, because a topper that sits low is seen against the cake rather than against the room.

• Five centimetres of clear air below the artwork is the minimum. Less than that and the bottom of the design is lost in the frosting texture.
• Do not let the topper stand taller than the cake itself. A 20 cm cake is around 10 cm tall, so a topper standing 9 cm above it is already at the limit of looking balanced.
• Candles change the maths. If candles are going in as well, raise the topper another centimetre or two so the flames are not in front of the lettering.

Tiered cakes

On a tiered cake the rule applies to the top tier only, not to the base. A three-tier wedding cake with a 30 cm base and a 15 cm top tier takes a topper sized for 15 cm, around 10 cm wide. Sizing it to the base produces a topper that overhangs the top tier and looks precarious even when it is perfectly secure.

When the name is too long

A topper is a fixed width and names are not. The instinct is to shrink the type until it fits, which produces a topper that is technically the right width and unreadable from more than a metre away. Better options, roughly in order:

1. Set it on two lines. "Alessandra" on one line at 20 cm is thin; on two lines it is twice the weight in the same width.
2. Drop to a shorter form. Most long names have one. The cake is for a person, not a passport.
3. Go wider, not smaller. If the cake allows 15 cm and you are working at 13, use the extra two.
4. Change the typeface before you change the size. A condensed heavy face fits far more letters into the same width than a rounded script at the same height, and stays readable.

Quick check before you print

Print the design on plain paper, cut roughly around it, and hold it above the actual cake, or above a plate of the same diameter. Ten seconds, one sheet of paper, and it catches every sizing error on this page.
