Choosing a 43 or 55 inch kiosk screen for your lobby is a common challenge for businesses deploying digital wayfinding systems or interactive displays in their lobbies. Unlike home TVs, kiosk screens in lobbies must serve multiple viewers at various distances, under lighting conditions that are not fully controlled. This article compiles real-world deployment experience in Vietnam to help you choose the right size from the start.
Choose a 43-inch screen for viewing distances under 3 meters (small lobbies, reception desks, elevators), and a 55-inch screen for distances of 3-5 meters (large lobbies, hotel lobbies, crowded waiting areas). Viewing distance determines the size, not the lobby area. Ideal mounting height: the center of the screen at the eye level of a standing person (150-160cm).

How does viewing distance determine whether to choose a 43 or 55 inch screen?
Viewing distance is the most important factor when choosing a kiosk screen. The basic rule: a 43-inch screen is suitable for viewing distances of 2-3 meters, while a 55-inch screen is suitable for distances of 3-5 meters. If viewers stand closer than 2 meters, a 55-inch screen can cause discomfort because they have to move their eyes a lot to cover the entire content.
Industry display standards (based on recommendations from manufacturers like Samsung, LG) recommend a minimum viewing distance of 1.5 times the screen diagonal. For a 43-inch screen (diagonal ~109cm), the minimum distance is ~1.6 meters. For a 55-inch screen (~140cm), the minimum distance is ~2.1 meters. The maximum distance to read medium-sized text is about 6-8 times the diagonal.
In real-world deployments in Vietnamese lobbies, we typically measure the distance from the most common viewer position to the screen before advising on size. If the lobby has a main walkway 2.5 meters from the wall, a 43-inch screen is sufficient. If guests often stand at the reception desk 4 meters away, a 55-inch screen is recommended.

A 43-inch screen is suitable for small lobbies under 30m², reception desks, elevator areas, and narrow hallways. The ideal viewing distance is 2-3 meters. Advantages: 25-35% lower cost than a 55-inch, easy to install, and does not dominate the visual space. Disadvantages: content is hard to read when viewers stand farther than 4 meters.
Cases where you should choose 43 inches:
- Small office lobbies (20-40m²): the distance from the entrance to the reception desk is usually 2-4 meters, a 43-inch screen behind the desk is just right.
- Elevator waiting areas: viewers stand only 1.5-2.5 meters from the screen, with short viewing times of 30-60 seconds.
- Small meeting rooms / auxiliary waiting rooms: narrow spaces, few simultaneous viewers.
- Small clinic hospital lobbies: where patients sit waiting 2-3 meters from the screen.
What type of lobby is a 55-inch kiosk screen suitable for?
A 55-inch screen is suitable for large lobbies of 30m² or more, hotel lobbies, shopping malls, and large hospital lobbies. The ideal viewing distance is 3-5 meters. Advantages: content is easy to read from a distance, creates a strong visual focal point, and is suitable for displaying complex wayfinding maps. Disadvantages: higher cost, occupies more space, and can be uncomfortable if installed closer than 2 meters.
Cases where you should choose 55 inches:
- 3-5 star hotel lobbies: guests often stand 3-5 meters from the reception desk, a large screen creates a modern feel.
- Shopping mall lobbies: pedestrians are at distances of 3-6 meters, requiring a large screen to attract attention.
- General hospital lobbies: patients and relatives stand in line 3-4 meters from the screen, needing to clearly read queue numbers and clinic information.
- Car and electronics showrooms: spacious areas, visitors at a distance.
