Why you want to display banners should help underline your marketing goals and provide direction about designing the banner correctly. What kind of message you want to convey impacts the size and design of the banner. Whether you are introducing some new product or want customers to take some action for buying some existing product will influence the choice of the call to action. The CTA for promoting an event will be different from offering free services for a limited period.
Banners for indoor use are different from those used outdoors because of placement for proper display. The custom banners used inside retail shops usually are smaller and preferably placed at eye level, whereas banners used in trade fairs might hang from some height to gain maximum visibility. Moreover, banners for outdoor use must be thicker and provided with wind slits so that it stays firmly in place by weathering the winds and other elements of nature. Moreover, selecting a shady spot will ensure better longevity of the printed surface, as sun exposure can make it fade faster.
Take a minimalist approach when writing the copy for banners so that you use fewer words to express your message, focusing on the most critical detail that you want to convey to people. Include a call to action that aligns with your marketing goal. The copy for introducing your business should contain all relevant information that makes it easy for viewers to contact the business. Again, for announcing an event, the emphasis must be on the date, time, venue and what you have to offer.
If you are using images in your banner, use only high-quality images of the largest file size. It will help you avoid the problem of odd discolouration or pixelation when you resize the image to suit your banner size. Work with vector files to minimize the chances of image errors as you can resize it without any distortion.
The better is your original image; superior will be its recreation when printing.
