Are all full-screen TVs large?

There must be a TV in the living room, but the size of the TV is still difficult to choose. Now you know that choosing too small will give people the feeling that the living room is not beautiful, and if it is too big, it will be uncomfortable to look at, so you must take it well. The size of TV screen is in inches, and one inch is equal to 2.54 cm. The screen size standard is determined by the diagonal length. What we usually call a 42-inch TV means that the diagonal length of the TV screen is 42 inches, which is about 106.68 cm. This number is the diagonal size, not the height or length of the TV, nor the area of the TV. TV screens are all rectangular, but some TV sets have different aspect ratios, some are 4:3, some are 16: 10. But does not affect the diagonal dimension. You can also calculate its body size, such as 1020 mm * 700 mm * 302 mm. This algorithm integrates the length, width and thickness of the TV. However, this algorithm has no unified standard, is not scientific enough, and can not clearly and uniformly reflect the size of many TV sets, so the number of diagonal inches is generally considered when buying TV sets. You can refer to the above when choosing TV size. I believe you can choose the one you are satisfied with. When you choose, you must first measure the size of your home.
