Sharing is caring!

Make your building-brick birthday party feel extra special with this colorful LEGO birthday banner. The free PDF includes every character needed to spell HAPPY BIRTHDAY, so you can create an eye-catching party decoration without drawing or designing anything yourself.

Each pennant features a bold white letter on a red, yellow, green, or blue brick-style background. The template also includes four blank pennants that you can decorate by hand with a kid’s age, initials, photos, or extra party messages.

Assemble the pieces, add ribbon, and your LEGO happy birthday display is ready to hang above the cake table, gift area, party entrance, or building station.

What Is Included in the Free LEGO Birthday Banner?

The PDF contains 17 pages:

• 13 pennants that spell the birthday greeting
• One blank red pennant
• One blank yellow pennant
• One blank green pennant
• One blank blue pennant

The file is already arranged in the correct spelling order. Each page is approximately 5.2 by 7.2 inches, creating pennants large enough to see across a party room without using an entire sheet for every character.

The four blank pieces make the set more flexible. They are not digitally editable, but you can personalize them after printing. If you need more than four, make additional copies of the blank pages.

Supplies for This LEGO Party Project

You only need a few basic craft supplies:

• The free PDF
• White cardstock or heavyweight sheets
• A color printer
• Scissors or a trimmer
• A single-hole punch
• Ribbon, baker’s twine, or string
• Tape or removable wall hooks
• Optional markers, letter stickers, or photos for the blank pennants

Cardstock gives the banner a sturdier finish and helps it hang neatly. Regular printer paper also works, especially if you need a quick, inexpensive decoration. For extra durability, glue the pieces to heavier stock or laminate them before punching the holes.

How to Prepare the Party Pennants

Download the PDF and open it in a PDF reader. Choose color printing and select Actual Size or 100% scale to keep the pennants at their intended dimensions. The PDF pages are smaller than standard US Letter size, so the design will appear with white space around it.

The “Fit to Page” setting may enlarge the image, depending on your printer. That can work if you want bigger pennants, but test one page before producing all 17 to make sure none of the edges are cropped.

For the brightest colors, choose the best-quality setting your printer and material allow. You don’t need borderless printing because you’ll trim each pennant around the edges.

How to Make a LEGO Birthday Banner

This LEGO party idea is easy enough to assemble the night before a celebration.

1. Prepare the PDF. Print all 17 pages, or only the 13 character pages if you do not need the blank pennants.
2. Cut out each pennant. Follow the outside edges and carefully trim the V-shaped notch at the bottom.
3. Arrange the message. Place everything in order before making any holes. Display the two words in separate rows for a compact backdrop, or put the entire greeting on one long strand.
4. Punch the holes. Make one hole near each upper corner. Keep them evenly spaced so the pieces sit at the same height.
5. Thread the pieces. Weave ribbon or string through the holes. Leave enough space at both ends to tie or tape it in place.
6. Display it securely. Use removable hooks, tape, or pushpins where appropriate. Keep long cords out of the reach of babies and toddlers.

How to Personalize the Pennants

The included PDF does not automatically add a name, but the four blank pieces give you a creative way to customize the decor by hand.

Try adding:

• The birthday child’s age, such as “7”
• One initial on each blank piece
• A short name of up to four letters
• Small party photos
• Building-brick stickers
• Words such as “BUILD,” “PLAY,” or “WOW”
• Blank pieces at the beginning, center, or end as colorful spacers

For a longer name, reuse the blank color pages until you have enough pieces. Choose a thick black marker or stickers with a bold font so the added characters are easy to see. A white paint marker is another fun choice for the darker backgrounds.

You can also turn one blank pennant into a matching LEGO birthday sign. Add the child’s age or a short welcome message, then mount it on sturdy material or place it in a small frame near the party entrance.

Ways to Display Your LEGO Birthday Party Banner

The primary colors make this banner easy to coordinate with a LEGO-themed party. Use it:

• Above the cake or dessert table
• Behind the birthday child’s chair
• Across a doorway or party entrance
• Over a table filled with loose bricks and building challenges
• On a wall as a photo-booth backdrop
• Across a mantel or bookshelf
• In the birthday child’s room as a morning surprise

For a two-row display, place HAPPY on the top strand and BIRTHDAY underneath. This layout photographs well and fits into a smaller space. If you have a wide wall or fence, place all 13 characters on one line.

This idea can also inspire the rest of your LEGO birthday party decor, especially if you use the same primary colors throughout the party theme.

Save the Banner for Another Celebration

After the party, slide the pennants off the ribbon and store them flat in a large envelope or folder. Label the envelope so everything is easy to find next year. If you laminated the pieces, wipe them clean before storing them.

You can reuse the birthday greeting for siblings, classroom celebrations, kids party events, or family birthdays. Replace only the hand-personalized pieces when you need a new name or age.

Building-Brick Party Ideas to Pair With the Banner

Carry the colorful theme through the party with simple activities and decorations. Set up a timed building challenge, fill clear containers with bricks for centerpieces, or invite guests to create a vehicle, animal, or birthday cake from bricks.

You can also pair the banner with these related printables and ideas:

• LEGO head printable
• LEGO man printable
• More LEGO activities and printables
• More free printable birthday banners

Keep the party table simple by using solid red, yellow, blue, and green plates, cups, napkins, and balloons. These colors coordinate with the banner without requiring expensive themed supplies.
