Modern linear gallery wall is, perhaps, one of the easiest to create and it looks well in any setting and space. All you need is to follow these steps to achieve a clean and modern look:
1. Keep things simple (black and white photos; art that shares the same color scheme)
2. Arrange your art in a linear pattern or create a 3x2, 3x3 or 4x3 display.
3. Make sure the distance (both vertical and horizontal) between your frames is consistent
4. Use frames and mats of the same color and style
