• Sequence of measurement

• Drywall tolerance

Accurate measurements are essential for proper fit when installing drywall. Use full sheets whenever possible and never force them into position. Start with ceiling first and install the panels perpendicular to studs followed by one wall. Then work in either a clockwise or counter clockwise direction. A good rule of thumb is to cut the drywall panel between 1/8 to 1/4 inch less then the opening. Professional drywall hangers have a joke about the drywall tape being two inches wide!
