Make a rectangular grid.

 If you have an even number of frames, and an even number of like-sized frames, you can build a grid. You can use as few as four paintings, hanging them in a square pattern. This arrangement is only limited by the amount of wall space you have to work with.[10]

• If you had 30 paintings that were one square foot, you could line them in rows of ten, five, or six.

• You can work with this arrangement with varied size paintings, but it will work better if you have frames that are all the same size.
