Balloon Sizes Explained
Every event calls for a different look. Here’s how balloon sizes compare and when to use them.
5-Inch Balloons
Small and stylish. Used for balloon garlands, centerpieces, or table accents. These are air-filled and perfect for detail work.
11-Inch Balloons (Standard)
The classic party balloon size. Great for bouquets, walls, and ceilings. Can be treated with Hi-Float for longer float time.
18-Inch Balloons
Fuller, more rounded look. Floats longer than standard sizes — ideal for premium balloon arrangements and hotel setups.
24-Inch Balloons
Large, round, and eye-catching. Used for organic arches, photo walls, and statement displays.
36-Inch Balloons (Jumbo)
The ultimate show-stopper. Perfect for weddings, corporate launches, and grand openings. Premium latex ensures long, stable float time.
Balloon Float Time Comparison
Float time depends on size, helium quality, and Hi-Float treatment. Here’s what to expect indoors:
| Balloon Size | With Hi-Float | Without Hi-Float | Ideal Use |
|---|---|---|---|
| 11” | Up to 3 days | 12 hours | Bouquets, walls |
| 18” | Up to 5 days | 12–24 hours | Luxury displays |
| 24” | Up to 10 days | 24–36 hours | Arches, backdrops |
| 36” | Up to 20 days | 24–36 hours | Weddings, launches |
Note: Outdoor conditions such as sunlight, temperature, and wind can reduce float time.
Why Helium Quality Matters
Many party stores use diluted “balloon-mix” helium that fades quickly. One Up Balloons uses pure, high-grade helium — the same quality trusted by London Drugs and luxury hotels. That means longer float times and brighter, photo-ready balloons for every event.
Cloudbusters & Giant Balloons
Cloudbusters are giant 4–8 ft balloons designed for large-scale events and outdoor displays. These powerful balloons demand high-quality helium and secure anchors. Perfect for corporate promotions, festivals, and parades.
How 5-Inch Balloons Transform Décor
Though they don’t float, 5” balloons add depth and texture. We use them in every balloon arch, wall, or ceiling design for a luxury, organic finish.
