Flags, Flagpoles and Banners

Pole height and flag size go together

A common rule of thumb is a flag length of about a quarter to a third of the pole height, so a 20 foot pole suits a 3 by 5 foot flag, with larger flags for 25 and 30 foot poles. Telescoping poles are portable, ground-set poles are fixed, and tall poles need solid footings. Check the maker's maximum flag size, the hardware and whether a halyard is included. Taller poles may need local permission.

Fabric, grommets and decorative banners

Most flags here are polyester, which is durable in steady wind, whereas lightweight nylon flies better in light breezes. The free edge frays first, so look for reinforced stitching or rip-proof fabric. Grommets, the metal-lined holes along the hoist edge, clip to the pole or halyard, so check the spacing matches your hardware. Decorative banners are different: party backdrops, glitter lettering and streamer sets are sold by the piece for indoor or short-term use, not months of wind.

Questions about Flags, Flagpoles and Banners

What size flag fits a 20 foot flagpole?

A 3 by 5 foot flag is the usual match for a 20 foot pole, with larger flags for taller poles. A rule of thumb is a flag length of about a quarter to a third of the pole height. Check the pole maker's maximum flag size too.

What are grommets on a flag for?

Grommets are metal-lined holes along the hoist edge. Snap hooks or clips on the halyard or pole rings pass through them, which holds the flag firmly while letting it fly. Check that the grommet spacing matches your hardware.

How long does an outdoor flag last?

Flags flown daily wear out faster than most people expect, because wind frays the fly edge and sun fades the colours. Choose sturdy polyester, bring flags in during storms, and replace one once the edge unravels.
