TIPS ON MEASURING FOR DRYWALL
To estimate the area for drywall, you'll need to take into account four specifications - wall height, wall perimeter, ceiling area, and any excluded sections not covered by the first three. (Note: If you have sloping walls, carefully follow the special instructions we have below these basic instructions.)
- Wall height
Measure from the floor to the ceiling, rounding to the nearest foot.
- Wall perimeter
Measure the length of each wall, and then add up the lengths from each wall together. (For example, if you have one room with four walls, you’ll measure the horizontal length of each of these four walls, and then add these measurements together.) Round the number you get for the total perimeter to the nearest foot.
- Ceiling area
Measure the width and length of your ceiling, rounding to the nearest foot. (Obviously omit this measurement if you don’t intend to drywall the ceiling.)
- Excluded sections
To account for any areas not included in the above calculations, measure the height and width of these sections separately. Enter into the calculator the sum of all the widths and sum of all the heights, rounded to the nearest foot.
- Special Case of Sloping Walls
If you have sloping ceilings, you’ll have triangular wall space beneath. To calculate the square footage for this triangle shape, multiply the length of the wall at the base by the height at the highest point of the triangle area, and then, divide this resulting number by two. (Area of a Triangle = Base*Height*0.5)
