Size of outdoor vertical advertising machines directly affects the display effect, installation method and applicable scenarios. The current mainstream sizes include 32 inches, 43 inches, 49 inches, 55 inches, 65 inches, 75 inches, 86 inches and 98 inches. These sizes have their own characteristics and are suitable for different environments and uses. Users need to consider viewing distance, installation space, content type and budget when choosing. The 32-inch advertising machine is a small vertical device with a screen ratio of usually 16:9 and a resolution of 1920×1080. It is suitable for installation in places with limited space such as convenience store entrances, elevator waiting areas or small catering stores. Its advantages are small size, flexible installation and low cost, but limited by size, the information carrying capacity and visual impact are relatively limited. The 43-inch advertising machine is one of the mainstream sizes in the mid-range. It also uses full HD resolution. Compared with 32-inch products, it has better visibility and information display capabilities. It is often used in medium-sized retail stores, hotel lobbies or corporate exhibition halls. This size strikes a good balance between price and performance. It does not take up too much space and can provide clear picture effects. It is suitable for viewing at a medium distance (2-3 meters is recommended). The 49-inch advertising machine belongs to the medium and large size. It usually uses a 4K resolution of 3840×2160. The display effect is more delicate. It is suitable for scenes that need to display high-definition pictures or video content, such as brand stores, large supermarkets or airport check-in areas. This size of advertising machine has significantly improved information capacity and visual expression, while maintaining a relatively reasonable energy consumption level.
55-inch advertising machine is one of the most popular sizes in commercial applications. The 4K ultra-high-definition resolution combined with a larger screen area can effectively attract the audience's attention. It is widely used in shopping mall atriums, subway station passages, large exhibition halls and other crowded areas. Advertising machines of this size have stronger expressiveness in content display and are suitable for playing dynamic video advertisements or interactive content. The recommended viewing distance is 3-5 meters. The 65-inch advertising machine is a large digital signage product. Compared with the 55-inch product, the display area has increased by about 40%. It is suitable for occasions that require greater visual impact, such as car 4S stores, flagship product display areas or large conference centers. This size usually uses a high-brightness panel (above 700cd/m²) to ensure visibility in bright environments. Sufficient load-bearing and stability need to be considered during installation. The 75-inch advertising machine has entered the super-large size category. The display area is equivalent to four 55-inch screens, which can create an immersive visual experience. It is often used in high-end commercial spaces, brand experience stores or large corporate exhibition halls. Such products are usually equipped with a more powerful cooling system and higher brightness (above 1000cd/m²) to cope with the needs of long-term high-load operation.
The 86-inch advertising machine is a professional large-size digital signage with an ultra-narrow frame design and a resolution of up to 8K. It is suitable for long-distance viewing and ultra-large space applications such as airport terminals, train station halls or large stadiums. Advertising machines of this size often require customized installation solutions and special structural support, and energy consumption is also significantly increased. The 98-inch advertising machine is the top size among outdoor vertical advertising machines. The display area is equivalent to four 49-inch screens, which can create stunning visual effects. It is mainly used in landmark commercial complexes, large exhibition halls or high-end brand flagship stores. This type of product usually adopts modular design and professional-grade panels, supports 7×24 hours of uninterrupted operation, and is equipped with advanced temperature control systems and anti-glare treatment to adapt to various harsh outdoor environments. From a technical perspective, as the size increases, the brightness, contrast and heat dissipation requirements of advertising machines are correspondingly increased. 32-55-inch products usually use conventional LED backlights, while products above 65 inches mostly use direct backlights or mini LED technology to ensure uniformity and brightness; in terms of installation methods, small-sized products mostly use wall-mounted or simple vertical brackets, while large-sized products require professional floor-standing brackets or embedded installation solutions. In terms of price, 32-49-inch products are economical options, 55-75-inch products are the mainstream of commercial applications, and 86-98-inch products are high-end customized solutions. In actual applications, 32-43 inches are suitable for small commercial spaces and auxiliary information displays, 49-65 inches are suitable for most commercial and public spaces, and 75-98 inches are suitable for occasions that need to create visual landmarks or long-distance viewing. With the advancement of technology, the cost of large-size advertising machines is gradually decreasing, while small-size products are developing towards higher definition and more intelligent directions. In the future, the size selection of outdoor vertical advertising machines will be more diversified, which can meet the refined needs of different scenarios.
