Helium Balloons: A Complete Guide for a Successful Event

Are you planning a wedding, birthday, or corporate event and want to create a memorable decoration? Helium balloons are one of the most visually impactful—and versatile—elements for transforming any space. This guide answers all your questions.

How long do helium balloons float?

The floating time depends on the type of balloon:

  • Latex balloons (30 cm): 8 to 12 hours indoors, less outdoors (heat, wind)
  • Latex balloons treated with Hi-Float: up to 24–48 hours
  • Mylar / foil balloons: 3 to 5 days, sometimes more than a week

💡 Pro tip: For a wedding or a daytime event, inflate your latex balloons on the morning of the event. For an installation the day before, always opt for Mylar balloons or Hi-Float treated latex.

Our biodegradable latex balloons

At Idéafête, we offer a complete range of 33 cm biodegradable latex balloons for all your events:

All our balloons are biodegradable and manufactured with respect for the environment.

What size helium balloons should you choose?

Size Recommended use
23 cm Table bouquets, filling arrangements
30 cm Standard for arches and columns
45 cm Strong visual impact, entrances and stages
60 cm+ Statement installations, photobooths
Giant balloons (90 cm – 1 m) Outdoor decoration, corporate events

Helium balloons indoors vs. outdoors: what you need to know

Indoors, helium balloons offer maximum lifespan and a flawless appearance. Outdoors, several factors come into play:

  • Heat expands helium and can cause latex balloons to burst
  • Wind accelerates flotation loss
  • Rain weakens Mylar balloons

For outdoor events on the French Riviera—where summer temperatures can exceed 30°C—we recommend balloons inflated to 80% of their maximum capacity and strong fastenings.

Helium balloons and safety: rules to follow

Safety is non-negotiable, especially when children are present:

  • Never inhale helium: helium displaces oxygen and can cause loss of consciousness
  • Avoid latex balloons for children under 8 (choking hazard)
  • Prefer Mylar balloons for low decorations accessible to children
  • Comply with local regulations on outdoor balloon releases (prohibited in many French municipalities for environmental reasons)

FAQ – Helium Balloons

Can helium tanks be rented?
Yes, but professional inflation is still recommended to guarantee flotation time and safety.

Are helium balloons eco-friendly?
Mylar balloons are recyclable. For latex balloons, choose certified biodegradable brands and avoid outdoor releases.

How much does a helium balloon decoration cost?
The price depends on the number of balloons, the type (latex, Mylar, printed), and the complexity of the installation. Contact us for a personalized quote.
