Should I hang drywall horizontally or vertically on walls?

In residential construction, hanging drywall horizontally is strongly recommended. It reduces the total linear feet of taped seams by up to 25%, places the tapered factory seam at comfortable waist level for easier finishing, and bridges framing inconsistencies across multiple studs.

How much joint compound do I need per drywall sheet?

On average, finishing drywall requires approximately 0.053 gallons of joint compound per square foot (or roughly 1.7 gallons per 4x8 sheet for a 3-coat finish). A standard 5-gallon bucket finishes roughly 90 to 100 square feet of hung drywall.

How do you calculate wall studs at 16 inches on center?

The standard carpentry rule of thumb is: (Total Wall Length in Feet × 0.75) + 1 stud for the end, plus 4 extra studs per corner and 2 extra studs per door/window opening for jacks and kings. Then add bottom sole plate and double top plates.

Why choose 4x12 drywall sheets over 4x8 sheets?

4x12 panels cover 48 square feet compared to 32 square feet for 4x8 sheets. On a 12-foot wall, a single 4x12 sheet eliminates troublesome vertical butt joints, resulting in flatter, professional walls with much less sanding.

How many drywall screws are needed per sheet?

For a 4x8 sheet fastened every 12 inches on ceilings and 16 inches on walls, budget approximately 28 to 32 screws per sheet for walls, and 36 to 40 screws per sheet for ceilings.
