Walmart Helium Tank Complete Buyer's Guide: Sizes, Prices, and Use

Breaking down the facts behind Walmart Helium Tank Complete Buyer's Guide: Sizes, Prices, and Use—uncover the essential highlights.

Walmart primarily stocks two consumer formats manufactured by Worthington Enterprises under the Balloon Time brand: the standard 8.9 cu ft helium tank and the jumbo 14.9 cu ft helium tank. Spotting the difference requires checking the fine print near the barcode, because box sizes look surprisingly similar on high shelves.

The 8.9 cubic foot model contains roughly 0.25 cubic meters of helium-air mixture. Manufacturers calculate their "fills up to 30 balloons" label based on small, under-inflated 9-inch latex shells. If you use standard 11-inch party balloons, expect that output to plunge to roughly 14 to 16 balloons.

The 14.9 cubic foot cylinder provides roughly 0.42 cubic meters of gas. It accommodates larger family gatherings, school functions, and arch setups. It comfortably fills roughly 26 to 30 balloons sized at 11 inches, or roughly 16 standard 18-inch foil shapes. Neither tank contains pure industrial helium; retail cylinders blend roughly 80% to 90% helium with ambient air to meet Department of Transportation consumer handling safety requirements.
