Screen size measurement refers to the diagonal length of a display screen, typically measured in inches. This measurement includes the entire screen area, excluding the bezel or frame surrounding it. It is commonly used for televisions, computer monitors, and mobile devices to indicate the size of the viewing area. To measure the screen size, a tape measure or ruler is used to find the distance from one corner of the screen to the opposite corner. This method provides a straightforward way to compare different devices, such as smartphones, tablets, and televisions, helping consumers choose the right size for their needs.
