Wall to wall is an idiomatic expression used to describe a situation or condition where something is completely filled or covered from one side to another, without any space or gaps.
In a literal sense, wall to wall refers to an area or space where the walls span from one end to the other, without any breaks or openings. For example, a room that is completely covered by walls on all four sides can be described as wall to wall.
However, wall to wall is most commonly used figuratively to describe an overwhelming or excessive presence or coverage of something. It is often used to convey the idea of a vast or continuous extent of a certain element or situation. For instance, a discussion that involves an extensive range of topics is said to be wall to wall or a book that contains comprehensive information about a subject may be described as a wall to wall guide.
The term can also be used to describe flooring, carpets, or other materials that cover an entire surface area without any visible breaks. In this sense, it denotes an all-encompassing coverage that extends from one end to the other, leaving no empty spaces.
Overall, the expression "wall to wall" signifies a state of complete or extensive inclusion, absence of gaps, or a continuous presence of something, whether it is physical, conceptual, or metaphorical.
