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.

A Sleeping Giant by Marshall Peterson

We share a great amount of information with employees and customers alike to ensure safe interaction with the gases and cylinders we sell. The following poem creatively illustrates the potential danger of pressurized gas. Some of you may recognize this as we have it posted in our store, as well as on our website . Though we do not intend to scare anyone away from using helium or the like, it's important to recognize the risks associated with gas under pressure. It commands great care and respect, as you'll see. A Sleeping Giant I am a compressed gas cylinder. I weigh in at 175 pounds with or without gas. I am pressurized at 2,200 pounds per square inch (psi). I have a wall thickness of about ¼ inch. I stand 57 inches tall. I am 9 inches in diameter. I wear a cap when not in use. I wear valves, gauges, and hoses when at work. I wear many colors and bands to tell what tasks I perform. I transform miscellaneous stacks of material into glistening ships and many ot...

Cylinder Sizes

We often get asked for height and weight measurements of helium cylinders. Whether you're renting or purchasing, it's good to know exactly what you're getting. It needs to meet your needs with regards to output, but in many cases, it also needs to be easily transported. If you plan to be mobile while using your cylinder, make sure it's something you're comfortable transporting. Will you be able load it into a vehicle unassisted? If not, will someone be available to help you? Do you plan on transporting it a lot or just occasionally? These are just a few questions to ask yourself when deciding on a cylinder size. Consider the following information to assist in your decision-making. Small Cylinder 55 cu. ft. Inflates approximately 65 12" latex balloons Stands 27" tall and is approximately 8.5" in diameter Weighs in at 26 lbs.* (aluminum cylinder) Medium Cylinder 125 cu. ft. Inflates approximately 200 12" latex balloons Stands ...

The New Helium Customer

Long before Helium Xpress Balloon Wholesale was founded, helium and balloon wholesalers found themselves selling most of their product to gift and flower shops. To say 'times have changed' would be a severe understatement. The New Helium Customer Gift and flower shops, while still relevant and thriving within their industry, are no longer the leading customers for many helium and balloon wholesalers. So who are these new customers? Well, they're a diverse bunch! They include car lots, apartment complexes, balloon decorators and event coordinators. Those may not sound too surprising, but what if I told you the new helium customers also include call centers, hotels, police departments and retail stores that have nothing to do with balloons? It appears helium and balloons are being used to promote new product releases, store openings, office parties, meet marketing objectives and even increase office morale more often. Our customers have come up with some very unique and...
