How Much is Enough?

If you've ever asked this question, you're not alone. The amount of helium needed to complete a job is sometimes difficult to determine. We provide a small chart on our website to guide customers toward the appropriate amount of helium. However, this chart assumes that all balloons being inflated are the same size.

When you're dealing with a combination of different sizes of latex and foil balloons, you need more specific information. Thankfully, Qualatex has provided a chart which lists the helium capacity of most sizes and types of balloons. It's a great resource that makes calculating exactly how much helium is needed much easier. Next time you're inflating a wide variety of balloons, simply refer to this guide: Qualatex Helium Chart

Remember that overinflating or underinflating will adjust the numbers shown. Ensuring you have some extra helium is always wise. Give yourself some wiggle room and consider popped balloons, as well as discrepancies in size.

How to Use the Chart: Quick Guide

  1. Search the left side of the chart (Balloon type) and locate the size and type of balloon that most closely matches what you're using.
  2. The next column, "Inflated", gives you the size of the balloon when inflated. Make sure the inflated size is the same size you intend to inflate the balloon to. It's important to note that all other information listed for that balloon will be based on the inflated size. For example, if you're looking up the helium capacity for an 11" standard latex balloon, the 0.5 cu. ft. listed only reflects the capacity for the balloon when inflated to 11 inches.
  3. Lift ability is helpful if you work with several balloons (or large balloons) and balloon weights. It is, quite simply, how much weight the specific balloon can lift. Make sure the balloon weights used weigh more than the sum of your balloons' lift ability!
  4. Once you've found the right balloon type, you're ready for some basic math! Take a look at the capacity listed. Simply multiply that number by the number of balloons you want to inflate. And now you know how many cubic feet you need! Of course, if you have several types of balloons, then you'll need to repeat the process and add up the figures you come up with along the way. Once you have your total, you'll be able to select the cylinder size which contains the most appropriate amount of helium for you.

Helium Cylinder Refills

At Helium Xpress, we can and do refill helium cylinders. However, there are certain criteria that must be met for us to legally and safely do so. Please note if you purchased a Balloon Time kit from a store such as Party City or Walmart, these tanks are disposable and cannot be refilled. If you have an industrial cylinder, please continue to determine your refill eligibility. Who Owns the Cylinder? This may sound like a trick question, but it's not. The answer to this question provides us with valid and important information regarding whether or not we can refill your cylinder. You might believe you are the owner of the cylinder because it's been on your property for as a long as you can remember, it has a self-made tag with your business name on it or because you personally paid for the cylinder. However, in some cases, it's still not your cylinder. This is why it's very important to purchase helium cylinders from a trusted source. Let us explain. The owner

Vinyl "Balloons"?

What are they? Well, we liken them to beach balls on a stick. They're composed of vinyl and are inflated with air. That's right, no helium required. We've seen them pop up at apartment complexes, car lots and storefronts. We get asked about these "balloons" from time to time, so let us review the pros and cons of purchasing and using these so-called balloons. At first glance, they sound like an efficient choice. They don't require helium so you can immediately suspend that expense. And they're reusable so you don't have to replace the balloons on a regular basis. Another perk would be that employees, office managers and store owners do not have to spend time inflating balloons on a daily or weekly basis. You can expect to spend around $30 per balloon if you're shopping from the cheaper end of the spectrum. However, this will include the pole, clamps, and other assembly items needed for that balloon. Various options are available regarding the

The Float Life of Helium Balloons

Customers always ask how long balloons last. This is sometimes difficult to answer as many variables can impact a balloon's float life. However, the answer is essential to party planning. Helium-filled balloons float due to the simple fact that helium is lighter than air. Because latex balloons are porous, helium slowly seeps through the pores. As less helium is left in the balloon, the balloon decreases in size and simultaneously floats lower to the ground until there is no longer a sufficient amount to keep the balloon afloat. The typical indoor float life of 12" latex balloons is 10-12 hours. If outdoors, this float life can be expected to decrease by at least half. Part of the reason a balloon doesn't float as long outdoors is due to temperature. The hotter it is, the more susceptible the balloon is to popping. In contrast, balloons typically contract in extreme cold, which decreases the size of the balloon. Ceilings that are texturized or have abrasive surfaces
