There are many gallery wall configurations to choose from. Uniform same-size prints lined up in a row or a mixture of collated images of all different sizes are just two possibilities of many. To successfully create a gallery wall, start by first choosing a design layout you like. Then measure out the dimensions of the photos or artwork you’re hanging and mark the wall with tape or faint pencil marks to help you visualize the end result. After this, gather the appropriate materials needed, whether that’s nails and a hammer or adhesive wall hanging hardware, and install your gallery wall.
