The advertising industry has recognized the trend of today's society that is marked with high mobility and based on that offered new ways of advertising whose properties are based on the movement of people. It is a visual advertising through posters. Posters in the present era can be found almost everywhere around us. If we just look into some of our healthcare and educational institutions, raise our eyes in public transport or just focus our attention while we stroll around the city, we will see that the posters are everywhere around us. Therefore, it should be mentioned that they can be part of outdoor advertising (billboard, city light posters, etc.) and internal advertising (posteres that are located within various public spaces). Also, each of these posters may also be classified by its format. Thus, outdoor advertising commonly uses large format posters, and posters that fall within indoor advertising are a much smaller format, usually B1 format and less. In addition, posters can be categorized by their theme, which is the message that they advertise and spread. Here it can be concluded that posters can advertise a political party, events in the city and so forth, or most commonly products and services. All this must be taken into account when designing posters, because these classifications are a part of the success of the graphic design of the posters. Of course, the idea is a major factor in successfully built posters, and with it goes the element of design that can make up posters which are typography, color, photos and so on. Thus, each of these factors and classifications must be taken into account if we want to design a visually appealing and accessible poster.
