Why is an 8x10 photo popular for portraits?

Understanding how big is 8x10, explanation of why it is a good format for portrait photography. It is 8x10 inches in size and enough surface area for the subject's facial features and other details to stand out clearly. The bigger the size, the more impact it has, as Visuals Clipping says, but it is easier to frame than smaller prints. Usually used for individual, family, professional, and other portraits that will be more visible when displayed.
