How to Set Up a Birthday Balloon Arch at Home (Step by Step)
Share
A balloon arch is the fastest way to turn a plain wall into a party backdrop, and you do not need a decorator or helium to make one. Here is exactly how to build a DIY birthday balloon arch at home in under an hour.
What you need
- An assorted pack of balloons in 2 to 3 colours (a balloon arch kit gives you everything in one box)
- A balloon arch strip (the plastic tape with holes)
- Glue dots
- A balloon pump (much faster than blowing by mouth)
- Optional: a Happy Birthday banner for the top
Step by step
- Inflate the balloons to different sizes. Mixing big and small balloons is the secret to a full, professional-looking arch. A hand pump makes this quick.
- Thread the balloons onto the arch strip. Push the knotted neck through each hole, alternating colours and sizes as you go.
- Stick it to the wall. Use glue dots to fix the strip in a curve or a straight line across your backdrop.
- Fill the gaps. Tuck small balloons into any empty spaces with extra glue dots so no strip shows through.
- Add the finishing touches. Hang a banner above it, or frame it with a foil curtain for extra shine.
How many balloons do you need?
For a standard half-arch behind a cake table (about 6 feet), 60 to 80 balloons gives a nicely full look. For a full doorway or wall arch, plan for 100 to 130 balloons. Most ready-made arch kits are sized for exactly this.
Frequently asked questions
Do I need helium for a balloon arch?
No. Arch balloons are air-filled and stuck to the wall, so helium is not needed. Helium only makes balloons float, which you do not want for an arch.
How long does a balloon arch last?
An air-filled arch holds up well for 2 to 3 days indoors, so you can build it the night before the party.
How long does it take to make?
With a pump, most people finish a half-arch in 45 to 60 minutes.
