Halloween Banner Printable: Free Pennant Letters, Assembly Guide & Party Signs

A store-bought “Happy Halloween” banner costs eight dollars and looks like everyone else’s. A printed pennant banner costs about a dollar in cardstock, takes twenty minutes to assemble, and says exactly what you want — your kid’s name, “Welcome Witches,” “Boo!” in letters the size of your forearm. This is one of the highest-impact Halloween decorations for the lowest possible effort.

Below is the complete printable kit: full banner letter sets (HAPPY HALLOWEEN plus extras), the assembly guide, stringing instructions, and coordinating party sign text — all written out so you can print this page and hang a banner tonight. Free. The designed matching bundle with illustrated pennants and party signs is in our Etsy shop, linked at the end.

Why a Printed Banner Beats a Store-Bought One

I’m not against store decorations — my porch is full of them. But banners are the one thing where DIY genuinely wins. Store banners come in exactly three phrases, and your party deserves better than the same “Happy Halloween” script lettering your neighbor has. Printing your own means custom words, custom colors, and a size that actually fits your space. A banner across a fireplace mantel needs different proportions than one across a garage door, and only you know which one you’re decorating.

It’s also the rare craft that’s genuinely hard to mess up. Cut along lines, punch holes, thread string. If a letter ends up crooked, it looks charming, not broken. Kids can do the cutting while you handle the stringing, and the whole thing becomes a pre-party activity instead of a chore.

The Printable Banner Letters

Print each letter on its own page (or one letter per quarter-sheet for smaller banners). Cut out the pennant triangles, and arrange them in order before you string anything.

BANNER SET 1: “HAPPY HALLOWEEN”
Print one letter per pennant, in this order:
H — A — P — P — Y    (star)    H — A — L — L — O — W — E — E — N
(The (star) is a decorative star/bat pennant between the words — print a plain patterned pennant with no letter.)

BANNER SET 2: “BOO!”
Short and punchy — great for a mantel or a dessert table:
B — O — O — !

BANNER SET 3: “WELCOME WITCHES”
For the front porch or entryway:
W — E — L — C — O — M — E    (star)    W — I — T — C — H — E — S

BANNER SET 4: “TRICK OR TREAT”
Classic for the candy station or trunk-or-treat:
T — R — I — C — K    (star)    O — R    (star)    T — R — E — A — T

EXTRA LETTERS & SYMBOLS
Print spares for custom names and phrases: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z, plus (star), (pumpkin), and ! — two copies of common letters (A, E, O, R, S, T) so you can spell names like “EMMA’S HAUNTED HOUSE.”

Assembly Guide: Print, Cut, String

1. Print on cardstock. Regular paper curls and tears at the holes; cardstock holds its shape. Orange, black, and purple cardstock look great mixed — or print the letters on white cardstock and let kids color the pennants first.
2. Cut the pennants. Cut each letter out as a triangle (point down) or a rectangle — triangles read as “party banner” more clearly. Leave a half-inch margin above each letter for the holes.
3. Punch two holes in the top corners of each pennant. A standard hole punch works; a small slit cut with scissors works in a pinch.
4. Thread your string. Ribbon, twine, yarn, or fishing line all work. Weave the string through the holes: in one hole, out the other, across to the next pennant. Leave 6–8 inches of slack between pennants so the banner drapes instead of pulling taut.
5. Lay it out before you hang it. Arrange all the pennants in order on the floor, step back, and check the spelling. I have hung “HAPPY HALLOWEEN” with two L’s in HALLOWEEN exactly once, and I will never live it down.
6. Hang with removable hooks or tape. Command hooks for walls, painter’s tape for windows, clothespins on a porch railing. Don’t use anything that damages paint — future you will be annoyed.

Printable Party Signs (Matching Set)

While the banner’s printing, make these coordinating signs on the same cardstock. Same look, whole party tied together:

WELCOME, MORTALS
(Front door — big letters, one page)

CANDY THIS WAY (arrow)
(Hallway arrow — tape to the wall pointing toward the treats)

WITCHES BREW — KID SAFE
(Punch table)

TAKE ONE… OR ELSE
(Candy bowl — the classic, and it works every year)

PHOTO BOOTH
(Props corner)

RESTROOMS (arrow down)
(Guests always ask. Save yourself the twentieth explanation.)

Sizing Guide: How Big Should Each Banner Be?

• Mantel or dessert table (4–5 feet wide): Quarter-page pennants (about 4 inches each), 8–12 letters max. “BOO!” or a name works perfectly.
• Wall or entryway (6–8 feet): Half-page pennants (about 5–6 inches each). “HAPPY HALLOWEEN” fits beautifully.
• Garage door or porch (10+ feet): Full-page pennants (8+ inches each). Go big — small letters disappear from the street.
• Rule of thumb: measure your space first, divide by the number of pennants, and that’s your max pennant width. Leave the 6–8 inch gaps in your math or the banner will come up short.

Tips That Save You a Second Print Run

• Print a test letter first. One page, check the size against your space, then print the rest. Ink and cardstock aren’t free.
• Cut with a paper trimmer if you have one. Scissors work fine, but a trimmer makes 15 identical triangles in two minutes and they actually look identical.
• Laminate outdoor banners. A $3 pack of self-seal laminating sheets from the craft store makes a porch banner survive rain and morning dew. Worth it.
• Save the extra letters. Toss them in a zip bag with the string. Next year you’ll want “HAPPY BIRTHDAY” in October colors for someone’s fall birthday, and you’ll already have the letters.
• Layer two banners. A big “HAPPY HALLOWEEN” across the top with a smaller “BOO!” or a name banner below it looks professionally decorated with about five extra minutes of work.

Want the designed version? The free letter sets and sign text above will decorate your whole party. But if you want the full illustrated bundle — patterned pennants in multiple colorways, matching party signs, and cupcake toppers in the same design — it’s waiting in our Etsy shop: fukroo.etsy.com.

That’s the whole project: print, cut, string, hang. Twenty minutes, about a dollar in cardstock, and a banner that says exactly what you want it to say. Measure twice, spell-check once, and enjoy the only decoration at the party that has your name on it — literally, if you print the extra letters.
