# Helium Balloon Chart — How Much Helium Do You Need?

> The Balloons and Weights Helium Balloon Chart shows exactly how much helium (in cubic feet) is required to inflate different balloon sizes and types. Use this as a planning guide when estimating helium tank rental needs for parties, events, and professional balloon installations.

- Note: Helium required can vary slightly depending on balloon brand. These figures are general estimates to be used as a guideline.

## Helium Requirements by Balloon Size and Type

| Balloon Size / Type     | Helium Required  |
|-------------------------|------------------|
| 7" latex balloon        | 0.15 cubic ft.   |
| 9" latex balloon        | 0.25 cubic ft.   |
| 11" latex balloon       | 0.50 cubic ft.   |
| 12" latex balloon       | 0.53 cubic ft.   |
| 14" latex balloon       | 1.02 cubic ft.   |
| 16" latex balloon       | 1.50 cubic ft.   |
| 30" latex balloon       | 8.00 cubic ft.   |
| 36" latex balloon       | 15.00 cubic ft.  |
| 16" orbz balloon        | 1.13 cubic ft.   |
| 18" foil balloon        | 0.50 cubic ft.   |
| 22" bubble balloon      | 0.96 cubic ft.   |
| 36" round foil balloon  | 4.40 cubic ft.   |

## How to Use This Chart

1. Determine the balloon size and type you plan to inflate.
2. Multiply the cubic feet per balloon by the total number of balloons needed.
3. Use that total to estimate the size of helium tank to rent.
4. Always rent slightly more helium than you think you need — tank output can vary.

## Tips for Helium Usage

- Helium tanks can be rented locally — search for "helium tank rental" in your city.
- A standard balloon inflator nozzle is needed to connect to the tank; B&W carries compatible inflator valves.
- To reduce helium costs, consider using air-filled balloons with balloon cups and sticks for table displays, garlands, and centerpieces.
- Air-filled latex balloons can typically stay inflated for up to 10+ days; air-filled foil balloons can stay inflated for months.
