Happy Birthday Yard Letters Made from Corrugated Plastic

These birthday yard cards are manufactured from 4mm corrugated plastic and are 18-inches in height. The height makes them easy to spot from a distance, making them ideal front lawn accessories that let guests know where the party is. Printing on corrugated plastic material also creates eye-popping, crisp colors that are both appealing and easy to spot from far away.

The durable corrugated plastic is printed with UV-resistant inks and is waterproof so that signs will not be damaged in the rain. This means that these happy birthday yard letters can be set up outdoors for more than one day. You can bring these happy birthday yard signs out year after year and make them part of a birthday tradition. Their shape and printed color will remain intact due to their durability.

Birthday Yard Signs Come with Stake Hardware

We include two different types of stakes with each order to best fit each yard card - H stakes and a beefy stakes. If the letter is wide, an H stake is used. If the letter is thin, then a beefy stake is paired with the letter. Both stakes easily push into a front lawn. Insert the stakes into soft ground until they are taut. When this is completed, then you can add the corrugated plastic happy birthday yard letters. There are flutes between the layers of the corrugated plastic. Insert the top of the stake through the flutes of the letter until it is securely on. If you would like to see a video about how to set up these happy birthday yard signs, view our “Videos” tab.

Frequently Asked Questions

Can I get my birthday yard signs to say something else other than “Happy Birthday”?

If you would like to create your own birthday greeting, we have a custom phrase product where you can add your own letters and symbols in a wide range of colors. Custom happy birthday yard letters are popular for parties where you want to say how old the honoree is or if you want to include their name. We also include other happy birthday yard signs to further decorate your yard.

What is the different between multicolor and gradient rainbow colors?

For the multicolor option, each letter is a different color. For instance, the H can be red, and the B can be blue. For the gradient selection, each letter has its own rainbow color scheme.

How do I know which happy birthday yard letters get the H stakes and which get the beefy stakes?

When your happy birthday sign arrives, it will include instructions showing each letter in the set and a stake below them. The stake type below each letter is the type of stake that is compatible with that symbol. For example, the balloon symbol includes the image of a beefy stake underneath it. This means that the beefy stake needs to be used to setup the balloon. This set includes 8 H stakes and 9 beefy stakes.
