Question 1

Do I need to include the ceiling when calculating drywall?

Accepted Answer

Only if you are hanging drywall on the ceiling. If you are only drywalling the walls, toggle the ceiling option to 'No' to save money on materials. A standard 12x12 room with 8ft walls has 384 sq ft of wall space, plus 144 sq ft of ceiling space.

Question 2

How many drywall sheets do I need for a 10x10 room?

Accepted Answer

A 10x10 room with 8-foot ceilings has 320 sq ft of walls. If you include the 100 sq ft ceiling, you have 420 sq ft total. Minus deductions for doors/windows, you will need roughly 13 to 14 standard 4x8 sheets (including a 10% waste factor).
