When asking how big is a 4×6 photo, it is useful to contrast the size with such options as 5 x 7 or 8 x 10. The 4X6 print is smaller and compact in size hence easy to store and share as explained by Visuals Clipping that this is the best size to be used in everyday memories and travel photos as well as large scale printing. Yet, it might not be as visually impressive as bigger framed prints on the walls.
