Buying balloons for party decorations: a guide for birthdays and celebrations

Creating attractive balloon party decorations needn’t be complicated. However, unclear product details, missing accessories or the wrong filling method can often lead to unnecessary expense. If you’re looking to buy birthday balloons, foil balloons or a complete balloon set, check the intended use, material, size and what’s included before you buy.

Common pitfalls when buying party balloons

1. “Suitable for helium” doesn’t automatically mean “ready to float”

Many latex and foil balloons can be filled with helium. However, this doesn’t mean helium is included. For individual balloons, you may also need helium gas for balloons, a suitable cylinder and, where necessary, ribbons or weights.

Latex and foil balloons also differ in how well they float. Latex is more porous, while foil usually holds the gas for longer. Either can work for decorations lasting several hours, but if you need them to last longer, check the stated float time.

2. Large images don’t tell you much about what’s actually included

A product photo showing a complete balloon display doesn’t always show what’s in the package. So be sure to check:

  • Number of balloons
  • Diameter or measurements when inflated
  • Filling method: air, helium or both
  • Included accessories, such as glue dots, fasteners or ribbons
  • Age and safety information

A balloon set with lots of individual pieces may also take considerably longer to assemble than individual foil balloons.

3. Themed balloons don’t always suit your existing look

Football balloons, unicorn balloons and Happy Birthday balloons each make a bold statement. Choose a design that works with your colour scheme, room size and occasion. A single novelty balloon can be the focal point, while neutral latex balloons add volume and help tie the colours together.

Key things to consider when buying balloons and foil balloons

Material and filling

Latex balloons are ideal for balloon clusters, garlands and table decorations. They can usually be filled with air or helium. Foil balloons are often available as letters, numbers or novelty designs, and frequently have a self-sealing valve.

If you’re using helium balloons, fill them shortly before the event. Heat can make foil balloons expand, while cold can cause them to visibly shrink. Avoid direct sunlight, radiators and hot cars.

Size and quantity

The size determines how visible a balloon will be and how much gas it needs. Examples from the range include:

  • 18-pack of 12-inch latex balloons
  • Round foil balloons with a diameter of 45 cm
  • Foil balloon sets with ten balloons, each measuring 46 cm in diameter
  • Larger novelty balloons measuring 58 × 44 cm

For a small flat, a few novelty balloons and a small pack of latex balloons are often enough. For a party with several tables or a photo backdrop, a larger balloon set is more practical.

Safety and storage

Uninflated and burst balloons should be kept out of reach of young children. Latex balloons can be swallowed, so many products have a minimum age of three years or must be used under adult supervision. This also applies to balloon accessories such as fasteners and glue dots.

Helium cylinders contain gas under pressure. Store them according to the instructions on the packaging, keep them away from heat and place them in a well-ventilated area. Dispose of a disposable cylinder after use in line with local recycling guidelines.

How to create a safe balloon display

First, decide whether you want the balloons to float or be fixed in place. For a floating display, you’ll need helium balloons, ribbons and weights. Air is usually enough for walls, arches and table decorations; glue dots or balloon tape can make them easier to put together.

Take care not to damage the valve on foil balloons with sharp objects. Tie latex balloons securely after filling them. For children’s parties, keep decorations out of reach of young children. Pick up and dispose of burst balloons straight away.

Balloon party decoration FAQs

How long do helium balloons last?

How long they last depends on the material, size, temperature and how much gas they contain. Latex balloons usually lose helium faster than foil balloons. Foil balloons with a self-sealing valve can be reused if handled carefully and left undamaged.

How much helium do I need for a party?

It depends on the size and number of balloons. A cylinder stated to have enough capacity for up to 50 balloons may be suitable for a larger display. Check the dimensions and packaging details to get a better idea of how many you’ll actually be able to fill.

Can I decorate with balloons without helium?

Yes. Latex balloons and many foil balloons can be filled with air, then attached to walls, tables or garlands. This means you won’t need helium gas for balloons, although they won’t float.
