Disregarding resolution when deciding on the best viewing distance is somewhat reckless. Can the distances for watching 720P, 1080P, and 4K content really be the same? The price range of 7000 yuan is quite broad, but for less than 5000 yuan, domestic products with similar technologies can be casually chosen based on functionality. Between 5000-8000 yuan, one might aim for a successful purchase from brands like Sony, Samsung, or LG. Personally, I’d recommend Sony’s 8500D, though you’ll only be able to get it in a 55-inch model.
Choosing the right screen size is closely tied to the viewing distance. Before purchasing a TV, it’s essential to know where it will be placed, the available space in the room, and how close you plan to sit. Then, consider the appropriate TV size. In the current market, mainstream TV sizes typically range between 40 inches and 55 inches. For a living room with a viewing distance of 2.5 meters, a 40-inch screen would be ideal; if the distance is around 2.7 meters, you could opt for a 42 or 43-inch screen. For distances over 3 meters, a 47, 48, or even 50-inch screen would offer a superior viewing experience.
Considering the typical living room area for middle-income households, which ranges from 30m² to 40m², the optimal viewing angle is approximately 20 degrees. With a viewing distance of 3 to 4 meters, a 50-inch TV would be an excellent choice for your living room. Once the size is decided, consumers often face another dilemma. There are numerous 50-inch smart TV options available. For instance, LeTV has released several models, indicating strong market demand.
Regarding the viewing distance for a 120-inch TV, we can make an educated guess.
Based on numerous experiences, there isn’t a strict standard for this distance. The key lies in personal preference. My suggestion is to visit a cinema and try sitting in different rows to find the most comfortable position. Ideally, measure the width of the cinema screen either by asking the staff or taking your own measurements. If bringing a measuring tape seems awkward, a laser distance meter is a practical alternative—available on Taobao. Simply using steps to estimate won’t suffice; you just need to keep this ratio in mind and apply it at home.
Taking the uMax120 as an example, according to the screen height, the viewing distance should be about 2 to 2.5 times that height. For a 120-inch TV, this translates to 3 to 3.7 meters. However, if the viewing distance is calculated as the length of the picture's focus line divided by 0.84, for a 120-inch TV, it would be around 3.6 meters. Watching a 120-inch TV from 3.6 meters, I found that the edges of the screen were slightly out of the peripheral vision. The eyes mainly focused on the center of the screen, missing some information outside the central area. Personally, I found that a distance of 4 to 4.5 meters seemed more appropriate, allowing for a full panorama of the entire picture.
