Funny 40th Birthday Cake Messages

What to Write on a Cake for 40th Birthday

A cake has little space, so short lines win. Here is how to get the lettering right, plus ready-to-pipe lines and captions.

What should you write on a 40th birthday cake? Use 3 to 7 words, one tone, and at most one name. Short lines are easier to pipe and easier to read from across the room.

Lettering tips for a 40th birthday cake

Match the line to the cake size. As a rule of thumb, a small round cake fits about 3 to 5 words, and a larger or sheet cake fits more. Your baker can confirm the space.

Keep punctuation light. One exclamation point is plenty. Use capital letters only for emphasis, such as the number 40.

Put the message on top. Use the side of the cake for borders, numbers, or a small date.

How to brief your baker

Send the exact wording in writing. Check the spelling of every name twice. Ask for a quick sketch or a photo of similar lettering. Order early, since popular dates fill up fast.

Pair the tone with the cake style

Plain frosting suits funny lines. Floral or pastel cakes suit sweet lines. A bold 40 topper works with either one.
