To add a sign to a balloon arch, choose a round board, acrylic, neon or custom numbers, then either hang it in the centre of the opening from a hook or command strip on the wall, mount it on an easel or backdrop stand, or build numbers into the garland. Keep it level, centred in the photo frame and in a font that matches the palette.
Quick takeaways
- Round boards are the classic “centre of the arch” look.
- Neon signs glow beautifully at night.
- Custom numbers make birthdays instantly personal.
- Hang it independently of the balloons so it stays level.

Where to place it
For a full round arch, the sign goes in the centre of the opening — exactly as in our lookbook photos — so it frames the guest of honour’s head in photos. For a half-arch on a wall, place it where the garland is lightest, often upper-centre, so it balances the heavy side. For custom numbers, build them into the fullest part of the garland at eye level.
Stylist tipHold the sign up, step back and look through your phone camera before you hang it — the camera tells you if it’s centred.
How to hang it
- Wall hook or strip — hang the sign directly on the wall behind the arch.
- Easel — stand it in front of the base for a floor-level sign.
- Backdrop stand crossbar — hang with fishing line for a floating look.
- Ribbon from the frame — for freestanding arches.
- Don’t hang signs from the balloons themselves — they shift and pull the garland.
Wording ideas
- Birthdays: “Happy Birthday [Name]”, “Wild One”, “Fabulous at 40”.
- Showers: “Oh Baby”, “A Little Pearl Is on the Way”, “Bride to Be”.
- Weddings: names and date, “Better Together”.
- Holidays: “Merry & Bright”, “Trick or Treat”, “Grateful”.
- Business: logo, “Grand Opening”, hashtag.
Font and colour
Match the sign to the palette: gold or white script on a champagne arch, a playful font on a kids’ arch, a gothic font for Halloween. Keep it to one or two fonts and make sure the main word is readable from across the room. For neon, warm white is the most flattering in photos.
