There are not a lot of companies that manufacture balloon cups that support air-filled foil balloons larger than 18-inches and large latex balloons and because of the current helium shortage more customers and decorators are turning to air-filled designs. 

Bargain Balloons carries Premium's line of Maxi Cups and Maxi Sticks that will support 18 to 28-inch foils and up to 24-inch latex balloons. Balloons larger than these will fall over as the cup is not large enough to fit the balloon. 

Maxi Cups are extra large and oval-shaped, while Maxi Sticks are extra thick for additional support. These are the largest balloon cups available currently. Customers typically helium-fill larger balloons which may be why balloon cups are not designed to fit jumbo balloons. If helium is not available and a balloon is larger than 24-inches and 28-inches– Bargain Balloons recommends using Hang Tabs, string or ribbon to hang them. 

A Stand-A-Balloon can be inserted into a lawn and can fit  30 to 36-inch balloons. Some balloons such as jumbo letters and numbers come with tabs used to hang them.
