Have you talked to the person who is making your banner about their recommendations? The guy that did mine told me what size things would look best and did a layout for me as a proof. Here's what we wound up with. I think it was 20" X 8'. Notice that the outside corners were left open so sponsors names can be added later. I put my company name on one corner so I can do some writing off of expenses.
