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:

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.
