3rd Birthday Banners

Third birthday party banners with trending themes like Three-Rex, Three-esta, and Wild and Three.

Third Birthday Letter Banners & Party Decor

By age three, kids have opinions about their own parties — and that makes planning even more fun. Our third birthday letter banners are laser cut from glitter or matte cardstock and arrive pre-strung on white twine. Just pull them out of the package, hang them up, and your party backdrop is done. No scissors, no tape, no threading letters onto string.

Three-year-old birthday themes tend to lean into whatever the child is obsessed with right now. Dinosaurs, princesses, trucks, mermaids — the sayings are where the fun really happens. A clever pun like "Three Rex" or "Young Wild and Three" instantly sets the tone for the whole celebration and gives guests something to smile about.

Frequently Asked Questions

What are the best party themes for a 3-year-old?

Dinosaurs, construction vehicles, princesses, and superheroes are consistently the most popular themes for three-year-olds. Character-specific themes like Paw Patrol, Frozen, and Bluey are also big at this age. Our banners work with any theme — just pick the font style and color that matches your decor. Bold, rounded fonts tend to fit the playful feel of a toddler party especially well.

Can I use a birthday banner as a reusable decoration?

Our banners are durable enough to carefully store and reuse at future events. The sturdy cardstock holds up well as long as the banner is handled gently. Many parents save their child's birthday banner as a keepsake or bring it back out for the next year's celebration. Roll it up loosely or lay it flat for storage to keep the letters in great shape.

What letter size is best for a third birthday party?

For most party setups, 7-inch or 9-inch letters work best. If you're hanging the banner behind a dessert table or across a wall in a party room, 9-inch letters make a bold statement and are easy to read in photos. For smaller displays — on a bookshelf, above a doorway, or on the front of a table — 7-inch letters are the right fit.
