How to Figure Out How Much Helium You Need

Party Rentals  /  Helium Tank Rentals

The following chart shows the Approximate Output of Balloons per Helium Tank Rental that we have available. Use the chart to choose the best size of helium tank you need to inflate your balloons.  How much or how little you transfer into a balloon is up to you but you will have the total amount indicated for the specific tank you order.​  If you need a larger amount of helium than we have in any one helium tank, consider combining 2 or more helium tanks in your rental order.  Please take care that others do not inhale (that's dangerous!) or release helium into the air unnecessarily as that may not leave enough helium for you to use in your balloons.​

Our 20 cu ft Helium Tank will fill about 40 standard size balloons inflated to 11".
Our 
30 cu ft Helium Tank Rental will fill about 60 standard sized 11" balloons.
Our 
55 cu ft Helium Tank Rental will fill about 110 standard sized balloons.
Our 
110 cu ft Helium Tank Rental can fill 220 standard sized balloons.
Our 
244 cu ft Helium Tank Rental can fill 488 standard sized balloons.
​Our 
291 cu ft Helium Tank Rental can fill 582 balloons.

Please keep in mind that these are estimates and actual output may vary. For the specific helium requirements of the balloons you have, please see the balloon manufacturer and use a balloon sizer.

​Our helium tank rentals are available for rent and delivery in Los Angeles, CA and surrounding cities within Los Angeles County only.
​​All orders require a $200.00 Subtotal Minimum plus a Delivery Fee.  The Subtotal is equal to the base rental rate (Day 1 rate) per item plus any services ordered in the item listing before adding to cart.  We charge per item per day (i.e. Saturday, Sunday, Monday, etc.) that you would like to have the rental items regardless of the amount of time in any day that they are actually used.  The 2nd day or more is charged at a discounted rate for most items.  You can see all rates in the item listings.  We do not charge sales tax on rentals.  We do not allow for customer "pick-ups" or subleasing of any rental items.  Our standard delivery and return service "Curbside" next to the delivery truck unless otherwise specified before adding to cart.  Orders requiring delivery and/or set up farther than curbside may incur additional charges depending on the additional time and labor required.  In each item listing, "Minimum Pathway Required" means the minimum width of the pathway required to the arrive at the desired drop-off and pick-up location. All prices and fees are subject to change without notice at any time.  The actual color of any rental item on our website may look different in person than what it appears on a computer, tablet or phone display. Any visual difference is not considered a defect or misrepresentation.  Any size or measurement stated in an item's title on this website is the nominal size and may differ from the actual size.  For all orders, full order payment is due at signing of our Rental Agreement.  After signing our Rental Agreement, half (50%) of the Total amount paid for the order is not refundable for any reason or circumstance and serves as the nonrefundable deposit to hold the order. The Total amount paid (100%) becomes nonrefundable for any reason 14 days or less before the scheduled Delivery Date.  This means that, once booked, if you decide to cancel your order 15 days or more before your scheduled Delivery Date, you will only receive a refund of 50% of the total paid and 50% will apply as the cancellation fee.  If you decide to cancel your order 14 days or less before your scheduled Delivery Date, then 100% of the total paid will be nonrefundable and serves as the cancellation fee.  For our full terms and conditions, please read our Rental Agreement which will be sent to you for your review and signature if we are able to fulfill your Order Request.
