4ft x 5ft - framed
Here's an example of how you can fill up a wall with smaller images like we discussed. This was for an art show so they arranged the pieces from floor to ceiling. For a home, I would arrange them differently. I would leave space between the floor and ceiling and the artwork. This is just to give you a general idea of how you could fill a wall with smaller pieces. I have a ton of beach images and palm trees in this size that go nicely together if you wanted to explore this type of arrangement. Also, they don't have to be square. Four or six in a rectangular shape would be nice together as well!
