8" x12" hangs pretty on walls, as well as, sitting on surfaces such as desks, side tables, or wall shelves.
12" x 18" is standard A4 size. If you are planning on getting a 3-piece set to span across a regular-sized cot, we recommend the 12x18 for the best effect.
16" x 24" work beautiful on its own on walls of small to medium-sized rooms. If you are new to decorating walls with framed posters, start here.
24" x 36" and 32" x 48" really pulls together a vibe of the room and leaves a lasting impression. It looks great hung but we love a 32"x48" on the floor, leaning casually against a wall and supplying many gram-worthy moments.
