Just because you hang a framed photo, painting or piece of wall art level, it doesn't necessarily mean that it will stay level. Over time, wall decorations can shift to either the right or left. Maybe you or a family member accidentally bumped the wall decoration while walking by it, or perhaps vibrations created in your home caused it to tilt. Regardless, it's frustrating when you hang a wall decoration so that it's perfectly level, only for it to shift shortly thereafter. But with a little work, you can keep your wall decorations in place.
Hang From a Stud
Wall decorations are less likely to shift if you hang them from a stud in the wall. In the United States, most builders space studs either 16 or 24 inches apart, meaning the walls in your home should have a stud every 16 or 24 inches. You can usually identify the location of studs by gently pounding the wall with the palm of your hand. If you hear a deep "thud" sound, it means there's stud present. If you hear a hollow sound, there isn't a stud behind the wall. Alternatively, you can use an electronic stud finder, which relies on magnetism to identify the location of studs.
Use 2 D-Rings and a Wire
There are several ways to hang a wall decoration. For the highest level of stability, though, you should use a standard mounting kit consisting of two D-rings and a single piece of wire. D-rings, of course, are metal rings that are placed on the back of the decoration. To prepare a wall decoration for hanging, you'll need to place two D-rings on the back of your decoration -- one on the left and another on the right -- after which you can connect the D-rings with a single piece of wire.
Choose the Right Location
Try to avoid hanging your wall decorations in narrow hallways and other high-traffic areas of your home. Instead, choose a more open location where it's less likely to get knocked or bumped.
Place Bumper Pads on Wall
There are special "bumper pads" that you can use to secure your wall decorations in place. They consist of soft material, such as plastic or rubber, with a self-adhesive back to protect the walls from damage. Just place one or two bumper pads on the wall behind your decorations to reduce the risk of shifting. Using bumper pads encourages decorations to lie flush with the wall. As a result, they won't easily shift or tilt.
