Planning your decoration shouldn’t feel like a guessing game! It’s important to buy just the right amount of helium. While you want to avoid overspending, buying too little can lead to missing out on the decorative flair you envisioned. So it’s a great idea to prepare and have plenty of helium ready to complete your project. Plus, keep in mind that balloon sizes can make a BIG difference! For example, an 11″ balloon actually needs TWICE the amount of helium compared to a 9″ latex balloon.

Gas cylinders are measured by cubic footage. To figure out how much you need, it’s best to gather a bit of information first.

Once you’ve got the exact sizes, you can pop that information into the calculator below to get started!
