Frequently Asked Questions

How big should a dinosaur party backdrop be?

Most home setups need 6 to 8 feet of width so a small group fits in the photo. Gate setups and outdoor scenes need more, often 10 feet or more.

What is the cheapest dinosaur backdrop?

A balloon arch around a doorway, like the Doorway Dino Balloon Arch, or a printed banner over a curtain costs the least. You only need balloons, a few foils and tape.

What colors work for a dinosaur backdrop?

Sage, olive and dark green carry the jungle look. Rust, orange and tan warm it up. For girls or first birthdays, pastel green, pink and lilac look soft and sweet.

Should I rent or DIY the backdrop?

Rent big props like gates, hedge walls and printed arch panels. DIY the balloon garland, since it saves the most money and only needs a few hours.

How many balloons do I need for a garland?

Plan about 80 to 100 mixed size balloons for a garland that covers the top and one side of a 7 foot backdrop. A full arch needs 120 to 150.

Can I set it up outdoors?

Yes. Pick a shady, flat spot, use weights or stakes for panels, and set up balloons close to party time, because heat and sun pop them fast.
