Drywall is available in many different thicknesses: five eighths of an inch, half inch and three eighths of an inch. The size of the boards can be four by eight feet, four by twelve feet or four by sixteen feet. Professionals usually use four by twelve foot boards in order to cut down on hanging time and have fewer seems, but four by eight sheets are lighter and easier to handle, which makes them the choice of most do-it-yourselfers.
Cutting and Hanging Drywall
When hanging drywall, the sheets are attached to studs or ceiling joists with either screws or drywall nails. Most professionals use screws and a screw gun for installation because they are less likely to become loose later and cause damage to the painted/papered finish. When installing drywall, the heads of the screws/nails should be driven extra deep so that they leave a dimple or depression in the drywall board. These dimples can later be hidden by covering them with joint compound and then sanding them to a smooth finish.
