All edges of all sheets of drywall must land on a solid surface such as a stud. A hanging drywall edge may work in the short-term, but in the long-term it can result in cracks and other serious wall issues.
While drywall alone can hold about 1.6 pounds to 2 pounds per square foot, mounting an object to the stud with the proper hardware allows the drywall to support up to 100 pounds.
Drywall nails
The nails drive into drywall and plaster walls at an angle, which allows them to use the wall surface as leverage and support. These are perfect for hanging items up to about 20 pounds. If you have a picture that is heavier than that, use a flat-mounted hook and anchor.
Corners will always have studs so they're a great place to start. Line a measuring tape against the corner and measure both 16 inches and 24 inches from the corner.
Then you either install another stud (or rafter) to support the end of the piece, or you cut the drywall piece shorter so that is supported by a stud. All the edges of a drywall panel require support from framing members.

If you are securing wood to drywall where there are no studs, use a strong construction adhesive. Only use nails if you are securing trim and baseboards. Mark your hanging point with a pencil. Take a nail-set, awl, or nail, and with a hammer tap a “pilot hole” into the wall.
Studs should be located every 16 inches or so, although your mileage may vary. “Tap on the drywall,” Lesh says. “It should sound hollow as you move to the left or right. As the sound changes, that indicates where the stud is.
For a professional finish, you have to tape, then wait. The average house has as much lineal footage of inside corners as it does flat seams. A good system for taping and mudding inside corners improves the look of every room and saves time. A quality drywall job starts with careful planning.
Anchors. Anchors are some of the easiest ways to hang anything in the walls without a stud. These work in different ways to keep screws from slipping out of their holes or otherwise damaging the drywall.
There are several reasons to install drywall from the top down. You want the line between the ceiling and the wall to be straight, and starting at the top helps you line up the drywall. If there is a gap at the bottom, or if you need to cut the drywall to fit, the floor trim will cover it.
Use plastic anchors. They go into the wall and then you put a screw into the anchor and screw it down as you would if screwing into a stud. Very simple and works like a charm!
How it works: A molly bolt is a screw encased with metal that expands in a predrilled hole to support medium-weight items. Best for: high-use and mid-weight range items, like coat hooks, or with lightweight items in the ceiling, such as smoke detectors. Weight limit: 25 to 50 pounds.
Whether you have a brick or uneven stone façade, or mounting a TV above a fireplace, mounting a TV can be tricky, but even more so when mounting a TV without studs. Even though drywall can support a TV up to 100 lbs., it's still brittle and the mount can require additional support.
Too few or too many: Follow the drywall manufacturer's instructions on the number of screws to use. Too few causes obvious issues, while too many means more mudding. Precision drives: Be careful how far you drive the screws if using a drill.
Use a Magnet.
Use tape or dental floss with a magnet attached and drag it across the wall to find the stud. This method works because the metal screws used to secure the drywall are typically secured to a stud. Wait until the magnet sticks to the wall and mark the location of the stud—it's that easy.
Drywall tape is a crucial element of any repair to drywall because it offers the necessary reinforcement and stops the drywall from deteriorating. Since there are many kinds of drywall on the market, determining the correct type of drywall tape isn't always straightforward.
In closets and other low-priority areas, don't tape and mud inside corners. Instead, caulk them. I first tried this trick on wall and ceiling corners 20 years ago—and those corners still look good.
You can use all-purpose compound for all three coats, but if you're doing a bigger job; using taping compound for the first 2 coats, and finishing compound for the last, will make everything go smoother.
Pipes. Plumbing pipes of PEX, copper, or galvanized steel are found behind walls mainly to serve kitchens and bathrooms. Pipes will run vertically more than horizontally through walls.
Regular 1/2-inch drywall has always been approved for use on 24-inch spacing on ceiling framing, but because of heavy sagging insulation, wet ceiling textures, or higher humidity, either a 1/2-inch ceiling board or 5/8-inch drywall was usually the best choice.
When a home is framed, the wall studs are usually spaced 16 or 24 inches apart. If you start in a corner and measure out 16 inches and you don't find a stud, you should find one at 24 inches.
Gluing Pros and Cons
Poor adhesive application increases the risk of unsecured baseboards. Glue is less forgiving than nailing when removing or repositioning baseboards. The potential damages from the glue can impact the appearance of your baseboards and lower the quality of your home.
How to hang heavy objects on drywall without a stud. Use a toggle bolt or anchor to hang the piece on areas with no studs, This Old House says. The weight of the piece, and the thickness of the wall, will dictate the toggle size.
✨Here's the trick for accent walls: Instead of nailing perpendicularly into your board, think about making an X. Put your brad nailer at a slight angle and install alternate nails through your drywall at two different angles.
