The best practice is to install strapping perpendicular to the joists and attach the gypsum board parallel to the strapping. This provides a buffer between the structure and the gyp board and support for the tape joints. Both of these effects reduce cracking at the joints.
Should ceiling drywall be perpendicular or parallel?
Drywall is typically stronger when hung in the long direction than it is in the short direction, which means less chance of sagging when attached perpendicular.
Which way do you run drywall on ceiling joists?
Installation starts in one corner of the ceiling with the length of the drywall panels running perpendicular to the direction of the ceiling joists. If the room is wider than the length of the panels, measure and cut additional panels so the panels meet on the center of a joist.

Structural strength – Drywall is typically stronger when hung in the long direction than it is in the short direction, which means less chance of sagging when attached perpendicular.
Should drywall touch the floor?
Drywall should NOT touch the floor. Allow for floor and wall expansion without cracking the drywall by keeping a 1/2-inch (1.27-cm) space between them. This space also aids in preventing moisture from seeping if the floor floods.
How much gap should be between sheets of drywall?
Always leave a 1/2-inch gap at the floor. This allows for floor and wall expansion without cracking the drywall.

How far can you overhang drywall?
In order to avoid this condition, it’s best to allow a bit of a gap between the floor and the drywall. Usually about 3/8 inches is ideal, but as much as 1/2 inch can still work.
Should drywall corners overlap?
It doesn’t matter for the walls, although it is standard practice to put drywall on the ceiling first so that the edges rest on the top edge of the drywall that you apply to the walls.
How should drywall meet at inside corners?

Instead of leaving a gap at the bottom, leave a gap in the center of the wall, and fill it with 3/8-in.
How many screws go into a sheet of drywall?
