There are a variety of ounce count options for vinyl banners such as: 13oz, 16oz, 18oz, & 9oz.
What that means is that for example, if you were to cut out and weigh a sqft of a 13oz 4’x12′ banner that sqft would weigh 13oz, and if you were to do the same with a 16oz 4’x12′ banner that sqft would weigh 16oz as well and so on. The higher the count the more heavy-duty the banner becomes. There is also a 9oz mesh material, mesh would typically be used in windy areas/times to make sure you don’t have to make holes in your banner and still have a clean look.
We only offer 16oz or higher for construction sites because anything lower wouldn’t last long term on a job site, it wouldn’t take long until a 13oz banner would get shredded on a job site.
