5″ Balloons: The Perfect Filler
Five-inch balloons are essential for modern organic balloon decorations. While too small for helium, they create beautiful texture and fullness in:
- Balloon garlands and organic arches
- Balloon walls and backdrops
- Adding detail to centerpieces
Tip: Use 3-4 five-inch balloons for every 11″ balloon to create a full, professional look.
11″ Balloons: The Most Popular Size
Eleven-inch balloons are the industry standard. They’re large enough to make an impact but affordable for volume decorating.
How Many 11″ Balloons for an Arch?
| 6-8 foot arch | 80-100 balloons |
| 10-12 foot arch | 150-200 balloons |
| 15+ foot arch | 250-400 balloons |
16″ Balloons: Enhanced Impact
Sixteen-inch balloons offer more presence without going to giant sizes. Ideal for centerpieces, enhanced bouquets, and mixing with 11″ balloons for dimension. Float time: 18-24 hours with helium.
24″ & 36″ Giant Balloons
Large balloons create dramatic focal points. Use 24″ balloons for entrance decorations and photo backdrops. 36″ giant balloons are perfect for confetti reveals, tulle-wrapped displays, and statement centerpieces.
