Air-filled garlands on a frame or strip last much longer than helium, which keeps standard 11-inch latex afloat for well under a day. An electric inflator saves hours. Never release balloons; many states and cities ban it. - [Party Tent Size Guide: Square Feet per Guest](https://eventcriteria.com/guides/party-tent-size-guide): Allow about 6 to 8 square feet per guest for standing cocktails, 10 to 12 for rectangular banquet seating and 12 to 15 for round tables, then add space for the dance floor, buffet, bar and DJ. A 20 × 40 ft tent (800 sq ft) seats about 55 to 65 guests at round tables. Weight every leg, choose fabric rated to CPAI-84, and check whether your city requires a permit. - [Portable PA Speakers for Weddings and Parties: How to Choose](https://eventcriteria.com/guides/portable-pa-speaker-for-events): For speeches and background music for up to about 100 guests, one powered 10 or 12-inch PA speaker on a stand usually works. For dancing or larger rooms, use two speakers and a subwoofer. Choose battery power for ceremonies away from outlets, check that a wireless microphone is included or supported, and in the US use mics outside the 600 MHz band, which is no longer allowed. - [String Lights for Outdoor Events: Bulbs, Runs and Power](https://eventcriteria.com/guides/string-lights-for-outdoor-events): Use outdoor-rated LED string lights for events: they draw a fraction of incandescent power, so far more strands can connect end to end, and they stay cool. Measure the space and multiply by about 1.5 for zigzag or swagged layouts. Support long spans with a guide wire, plug into GFCI-protected outlets, and never exceed the maker's maximum connected run. - [Tablecloth Size Chart for Banquet, Round and Cocktail Tables](https://eventcriteria.com/guides/tablecloth-size-chart): For a floor-length look, add about 60 inches to each table dimension (a 30-inch drop on each side of a standard 30-inch-high table). A 6 ft banquet table takes a 90 × 132 inch cloth, an 8 ft table 90 × 156, a 60-inch round a 120-inch round, and a 72-inch round a 132-inch round. For a lap-length drop of about 15 inches, add 30 inches instead. - [Wedding Backdrop Stands: Sizes, Types and Setup](https://eventcriteria.com/guides/wedding-backdrop-stand-guide): Adjustable pipe-and-drape stands, typically up to 8 to 10 ft tall and 10 to 20 ft wide, are the most flexible backdrop for ceremonies, sweetheart tables and photo walls. Round, square and hexagon arch frames suit balloon and floral installs. Check the height and width range, base weight, how drapes attach and whether the venue requires flame-retardant fabric.
