Introduction

Galaxy party decor usually means a mix: deep purple and navy latex balloons, a few chrome foil planets, and star confetti pieces to fill the gaps. Knowing which type you are ordering prevents a deflated arch the morning after setup.

Balloon count and inflated diameter in inches, since kits often list uninflated flat sizes.
Latex versus foil, because helium filled foil holds shape far longer than standard latex.
Whether the set includes a pump, strip tape, glue dots, or only the balloons themselves.

Plan the arch length first, then buy the count that covers it with a few spares.

FAQs

A common estimate is about seventy to one hundred balloons for a six foot garland when you mix five inch, ten inch, and twelve inch sizes. Order extras, since a few always pop during assembly.

Arches and garlands are usually air filled and taped to a strip, so no helium is required. Reserve helium for foil planets or star shapes that you want floating above a table.

Air filled latex garlands can be built the night before if kept indoors away from heat and direct sun. Helium filled latex starts sinking much sooner, so inflate those close to the event.

Deep navy, plum, black, and chrome silver read as galaxy, with metallic gold stars for contrast. Confetti filled clear balloons add depth without needing more color, which keeps the palette from looking muddy.

Uninflated and broken latex pieces are a choking hazard for children under eight, so supervise setup and clean up fragments immediately. Foil shapes also conduct electricity and should stay away from power lines outdoors!
