The top one is 7" tall and 23.75" wide. It has five folding panels, but you could also make one with three panels. To do this, you make one initial document on photoshop, then expand the canvas size to the desired overall size, then copy and paste additional images into the document. Don't forget to match your images in size and resolution, in other words, if your first image is 300 ppi 5x7", make sure that the other images match.
