Weatherproof outdoor banners bring color and visibility to streets, campuses, and event spaces. They also give the wind a surface to push against. That force travels through the banner and its mounting hardware into the pole. Understanding that path helps you choose banners and hardware suited to the installation.
Wind load is the force wind exerts on a surface. For a street pole banner, it depends on outdoor wind speed, banner size, orientation, and how the banner moves. In a simplified wind-pressure calculation, doubling wind speed roughly quadruples the pressure put on the light pole. A larger pole banner also presents more surface area which increases the importance of installing wind resistant signage.
Banner dimensions are therefore only part of the planning conversation. The pole’s condition, the number and placement of banners, and local wind conditions matter too. The pole owner or a qualified engineer should confirm what a particular pole can support.
A fixed bracket holds a banner in position as wind pushes against it. BannerSaver™ uses a spring-loaded bracket that flexes as wind force increases. When conditions calm, the spring returns the banner to its display position.
In the BannerSaver™ wind tunnel test, two 30-by-80-inch banners were mounted on a simulated pole. The test shows the BannerSaver™ setup stayed below 200 pounds of measured pole force at wind speeds above 90 mph, while the other static bracket systems tested exceeded 500 pounds under the same conditions. It reports an 87% calculated reduction in effective banner area for that setup.
*Those results describe the tested configuration, not a load rating for every pole or installation.
The bracket is just one part of the installation. The BannerSaver™ pre-installation guide lists brackets, fiberglass arms, pins, zip ties, and metal banding as necessary components. Banding is purchased separately, and the choice depends on banner size and pole shape.
BannerSaver™ recommends standard banding for the standard model on round poles with banners up to 20 square feet. Heavy-duty banding is required for large and extra-large brackets and is recommended for most square poles. For more information, view our guide on standard banding vs heavy banding.
Hardware needs inspection after it goes up. BannerSaver™ recommends returning two to four weeks after installation to tighten bands if needed, then checking banding quarterly and after high-wind storms. Loose or damaged components should be addressed promptly.
The practical starting point is simple: know your banner dimensions and pole details, select the appropriate brackets and banners, and plan for regular checks. If you’re preparing a light pole banner program, contact BannerSaver™ with your banner size, pole details, and location to discuss a suitable hardware setup. You can also request a free sample kit to explore BannerSaver™ materials and options for your outdoor banner project.
What light pole banner sizes are most common?
There is no single standard size for street pole banners. Common dimensions vary by pole, bracket system, viewing distance, and local wind exposure. BannerSaver™ offers different bracket and pole banner sizes, so confirm the dimensions and pole details before selecting compatible hardware. For more guidance, view our height and sizing guide.
How do you match a pole banner to a bracket set?
Start with the pole banner dimensions, square footage, and pole dimensions. The bracket type, fiberglass arms, banding, and other hardware should be selected to match the banner and pole configuration. For an expert opinion, our team is available to help through the quote form below.
How can I install street banners on light poles safely?
The BannerSaver™ installation guide lists a complete set of instructions on how to install pole banners safely. For a quick and professional installation without worry, our nationwide installation team can set up your BannerSaver™ system for you.
What are the best materials for durable banner poles?
BannerSaver™ pole banners always use vinyl to effectively spill winds. Additionally, the pole banners operate their best without wind slits, so your graphics remain on full display regardless of outdoor conditions.
How does street pole banner size affect wind load?
A larger banner presents more surface area to the wind, increasing the force transferred through the banner and hardware. Banner size should therefore be considered alongside pole strength, mounting configuration, and local conditions.
