When hanging pictures on a wall, it's necessary to find the wall stud to hold the items properly. Nails hold pictures securely when hammered into a wall stud instead of only drywall. Hammering a nail into drywall not only does little to hold the picture in place, it may end with a chunk of drywall ripped out as the picture falls to the floor. After locating a wall stud, determine the correct nail size for the picture you want to hang.
Glide a stud finder slowly over the wall area. The stud finder emits a sound or light when it crosses over the wall stud. If you do not have a stud finder, use a bright flashlight, or remove the lampshade from a small lamp. Turn on the lamp or flashlight and hold it 1 foot from the wall. Look for drywall tape or nails that cover the wall studs. Mark the stud's area with a pencil.
Place a nail over the marked area. Angle the nail so the head tips slightly up.
Tap the nail head gently with a hammer. Drive the nail 3/4 of the way into the wall stud, allowing a portion of the nail to stick out.
Hang the picture on the nail head, centring it on the wall.
Use thick nails for heavier pictures so they don't fall.
