Steps Involved in Building a HouseSpike's Calculators

Drywall Calculator for a Room

Estimate the amount of drywall materials needed for a room. This calculator will provide you with a rough estimate of the materials needed to board and tape a room.

It does a board count based on board size and the square footage of the area's.
To actually get a good estimate of boards needed and reducing the amount of joints, a wall should be measured for the best fitting size board. If you have a 10' wall with a height of 8' you should use 2 4'x10' boards. If that same wall has a 9' height then look at using 2 boards with a width of 4'6" (54") eliminating one joint length wise.

Opening's square footage allows you to subtract area's that do not need board. Only subtract very large openings and for a few smaller openings consider it as waste, even for a door, as more than likely depending on its location, you will waste some of the material's

The wall and ceiling results are separate, as quite often the ceiling will require a different board thickness than the boards used for boarding walls.

Tape needed is calculated from the amount of joints in the walls and ceilings that need to be taped.

Amount of screws needed is based on an average of 1 screw per square foot of wall area and 1.25 per square foot of ceiling area. Depending on stud and joist spacing it could be slightly more or less.

Ready mixed joint compounds are the standard compounds and come made for taping, topping and there is an all purpose one. Calculation is based on 64 lbs per 450 square feet of board.

Lightweight all purpose joint compound does it all from start to finish and is easier to work with. Calculation is based on 5 gallons for 450 square feet of board.

Note: There is no allowance for waste calculated in the results

The Calculation

  1. the length of the room
  2. the width of the room
  3. height of the wall
  4. the size of the board you are using. Preset @ 8' x 4' but can be changed.
  5. combined square footage of wall and ceiling openings

Results

  1. square footage of the ceiling
  2. square footage of all the walls
  3. number of boards needed for the ceiling
  4. number of boards needed for the walls
  5. length of tape needed for the joints
  6. amount of screws needed
  7. ready mixed joint compounds
  8. lightweight all purpose joint compound
