Different rules apply indoors than outdoors. There is artificial light instead of sunlight, the surface is rarely flat and even, and whatever is hanging there is viewed and touched at close quarters. That has a greater impact on the choice of materials than the size does.
The first distinction is the surface. A wall asks for something other than a window, and a floor That’s another matter altogether, because people walk over it. The second question is whether it should stay in place or be removed. For work that needs to be taken down after a season, there are materials available that leave no traces of adhesive.
Another important factor indoors is sheen. PVC reflects light under spotlights, whereas fabric does not. That is why textiles inside is the norm and PVC is the exception, exactly the opposite of outside.
And there is one issue that crops up more often than you might expect in an office or meeting room: it echoes. In this case, the solution isn’t the printing itself but the materials used, and if there are felt and cork panels designed to dampen noise whilst also carrying your image.
