Which Sizes Actually Work for a Balloon Arch?
Balloon arch sizes typically range from 5 to 18 inches, with the 11 inch latex balloon serving as the go to anchor size for most structures.
- 5-inch balloons fill small gaps between larger ones
- 11-inch balloons build the main shape of the arch
- 16-inch balloons add fullness and roundness
- 18 and 24 inch balloons work as bold accent pieces
- 36-inch jumbo balloons create a dramatic focal point
Knowing what size balloons for a balloon arch to use in each spot is what separates a homemade look from a professional one.
Choosing Sizes Based on Arch Style
Balloon arch sizing really comes down to the style you’re going for and how big your actual venue space or opening is.
The what size balloons for balloon arch decisions often depend on the vibe you want. This traditional organic arch features a combination of sizes to create a natural and airy effect. Most minimalist arches consist of a single balloon size for a simple and crisp design. A grand or luxury style arch leans on jumbo balloons paired with smaller fillers for maximum visual impact.
How Many Balloons You Will Need?
For a standard garland, plan on roughly 12 to 15 balloons per foot, or about 18 to 25 per meter depending on how full you want it to look.
Understanding how many balloons to make a balloon arch is just as important as picking sizes. It usually comes down to the length of the arch.
- 6-foot arch typically needs 60 to 70 balloons
- 8-foot arch typically needs 90 to 100 balloons
- 10-foot arch typically needs 120 to 140 balloons
- 12-foot arch typically needs 150 to 170 balloons

- Indoor or outdoor placement, since wind affects smaller balloons more
