24 inch is the size between the everyday 18 inch and the window 40 inch: big enough to anchor a wall or a photo backdrop, small enough that a customer will still pay for two. Vendors use it when the display has to read in a photograph rather than on a shelf.
Roughly 0.6–0.8 cu ft of helium and about six days of float when filled to 90%. Most of our 24 inch output is printed on existing character, heart and star dies, so custom artwork starts at 50 pcs without a new tool.
