Whether you rent or own, you probably want to put some art on the walls and spice up your space. You also probably want to do this without damaging the walls trying to hang the same photo five times or having it fall down over and over again. Here's how to hang your art and posters the right way the first time without wrecking your walls in the process.
How you should hang art on the way depends largely on how heavy and large the poster or frame you want to put up actually is. Still, the key to hanging photos without killing your walls starts with planning, long before you put the first nail in the wall or drill the first hole.
Pick your space. If you don't already know where you want to hang your art or posters, now's the time to start looking and making sure that the space you want your art to hang is large enough to accommodate it. Also, make sure you're not cramming so many frames, photos, and posters in such a small space that you can't manage them or space them evenly.
Hang at eye-level. One design tip that will help you maximize the use of your wall space without losing sight of your art is to always hang your art at eye-level where you'll be able to see them without having to crane your neck up or look down your nose to see what you're hanging on the wall. If you don't want to eyeball what "eye level" is, run a tape measure from the floor to the ceiling, and have someone else mark on the measure where your eyes naturally rest when you're standing a foot or two away from the wall.
Get a stud finder. While you may not need to hang light posters in acrylic or plastic frames or photographs from a stud, if you do have an expensive piece in a heavy frame, you should know where the studs behind your walls are. Even if you don't need your studs for your artwork, take a stud finder and mark-perhaps at the top of your wall where it meets the ceiling-where the studs are with a pencil. Then you'll never need to worry again.
Mount the Hardware
Measure first. Make sure you mark off any places you need to hammer nails or drill holes for brackets before you try to hang the piece. Use a straight-edge, ruler, or level to make sure the sides are level before you actually hold the art up to the wall. Mark the center line (the halfway point between the bottom and the top of the art, which should also rest at eye-level,) the edges, and all the sides. When you're finished, putting the art up should be like fitting a puzzle piece into a slot. Making sure you take the time to mark where the art will go first and that it's level and spaced well from other pieces will save you from mounting a piece only to take it down and have to re-mount it somewhere else later.
Use the right tools. Picture hanging kits, easily available at most hardware and department stores, often have all the materials you need to hang most common frames on your walls. Light pieces like photos, movie posters, and other art will likely require just a nail, or a nail and a bracket or picture hanger (most light frames have a bracket on the back already.
If you're facing something over 25lbs however, this is where you'll be happy you marked the studs. Depending on how heavy the art is you may consider using a plastic wall anchor in the drywall, or solidly mounting the art in the stud using a mounting bracket. Don't use drywall screws in wood, and don't use wood screws in drywall – go to your local hardware store and find the type of picture hanger for the size and weight you're dealing with. Using the wrong mounting brackets or tools will inevitably lead you to waking up in the middle of the night to the sound of your art crashing to the floor.
Use blank paper for dummy art. There's no need to try and hold your art or frame up to the wall while simultaneously marking or drilling holes in it. Put the art on the floor, and lay notebook or construction paper around the edges, then tape the paper together so you have a large sheet that's the same size as the piece you want to hang. Then use the sheet, now the same height and width as the art, as a guide that you can tape to the wall to mark your holes or even drill your holes through the hanging paper without worrying if you're in the right spot.
Mount the Art
Once you've measured, centered, and mounted your hardware, placing the art on the wall should be a simple task, and you shouldn't have to spend too much time tilting the art to make sure it's level. You can save the paint on your walls from scuffs and scratches though by adding small adhesive bits of felt to the corners or bottom of the frame where it's in direct contact with the wall. If you don't have anything like that, a bit of post-it note or masking tape will work too: anything to keep the frame from scraping against the wall directly.
