What size number balloons should you buy for milestone birthdays
Buy 34–40 inch giant foil number balloons for floor displays and photo backdrops, and 16-inch air-filled foil numbers for wall banners or cake tables. Note that 16-inch foil numbers are too heavy for their gas volume and will not float with helium.
Do 16 inch number balloons float with helium?
No. The foil seam weighs more than the small pocket of helium can lift. Inflate 16-inch numbers with air using a straw and hang them from ribbon or glue dots.
How do you stop giant number balloons from twisting?
Tie ribbon to both bottom tabs and anchor each to a 150 g weight, or tape the back of the two digits together with a hidden loop of painter’s tape.
