Room Dimensions

'How many screws per sheet of drywall?', 'answer' => 'A general rule is 1 screw per square foot of drywall. This calculator uses that standard. Screws should be placed 12"–16" apart on studs and 8" apart on edges.'], ['question' => 'How much joint compound do I need?', 'answer' => 'A standard rule of thumb is approximately 0.05 bags (of a 4.5 gallon bucket) per square foot of drywall. Three coats are typically applied: tape coat, fill coat, and finish coat.'], ['question' => 'Should I hang drywall horizontally or vertically?', 'answer' => 'Horizontal hanging is generally preferred on walls as it reduces the number of seams and places the butt joints (harder to finish) in the middle of the wall. Vertical hanging may be preferred in rooms with very high ceilings.'], ]" />
