In standard home construction, about 28 screws are needed to properly attach a 4-by-8-foot piece of drywall. That's if the panel is going on a wall. If it's going on a ceiling, it'll take about 36 screws. The number of screws is the same whether you're installing the panel vertically, meaning the installed panel looks 8 feet tall by 4 feet wide, or horizontally, in which the panel is 4 feet tall by 8 feet wide.

## Studs

You hang a drywall panel by attaching it with screws to the wall studs. The vertically set pieces of lumber give the wall its structure. In modern home construction, studs are typically set 16 inches on center, meaning the distance from the center of one stud to the center of the next stud is exactly 16 inches. A 4-by-8-foot panel of drywall is 48-by-96 inches. Both dimensions are evenly divisible by 16, so a full panel will set neatly on the studs. A panel hung vertically will cover the spaces between four studs, while a panel hung horizontally will cover the spaces between seven studs.

## Hanging a Panel Vertically

When screwing drywall into wall studs set 16 inches on center, professionals recommend 16 inches of space between the screws. So when hanging a panel vertically on a wall, start with four screws across the top -- one at each corner and two at 16-inch intervals, which will line up with the studs underneath. Moving down from each of those top screws, set a screw into the studs every 16 inches. The last screws will be at the bottom edge of the panel. In total, the panel will have four columns of seven screws apiece, for a total of 28.
