So you have the perfect banner in mind for your tradeshow or exhibit and have worked hard to design it so that your message is clear and appeals to your target audience.  Because you desire portability and reuse you have decided to add a banner stand and will need to pick one that fits your requirements.  You may have decided based on previous tradeshows and booth set-ups that it needs to be a two-sided banner, so that your message is displayed from both the front and back.  Your choices may include retract-ability.  All of these considerations, as well as the width and height of the banner, and whether or not you want the banner sized for a table-top display, will affect your choices.  Banner stands range not only in size but also from economy to premium models, so the many choices will need to be considered carefully.
