How to Calculate Drywall

Drywall installation is a crucial step in the construction of any building or renovation project. It is important to get the right amount of drywall needed for the job to avoid over-ordering or under-ordering. Both can lead to unnecessary expenses and delays in your project timeline.

Step 1: Measure the Room

The first step in calculating drywall is to measure the room or space where the drywall will be installed. Measure the length and width of each wall and record the measurements in feet. Multiply the length and width measurements to determine the square footage of each wall. Add the square footage of each wall together to determine the total square footage of the room.

Step 2: Account for Openings

Once you have determined the total square footage of the room, you need to account for any openings in the walls such as doors and windows. Measure the height and width of each opening and subtract the total square footage of all openings from the total square footage of the room.

Step 3: Determine the Number of Drywall Sheets

Determine the number of drywall sheets needed for the project. Drywall sheets are typically 4 feet wide and 8, 10, or 12 feet long. Divide the total square footage of the room by the square footage of a single drywall sheet to determine the number of sheets needed. Round up to the nearest whole number to ensure you have enough drywall for the job.

Step 4: Account for Waste

It is important to account for waste when calculating drywall. Cutting and fitting drywall sheets can result in a lot of waste, so we recommended adding an additional 10% to the total number of sheets needed to account for waste. For example, if you need 20 sheets of drywall, you should order 22 sheets.

Step 5: Calculate the Joint Compound and Tape Needed

After calculating the number of drywall sheets needed, it is important to calculate the amount of joint compound and tape needed for the project. A good rule of thumb is to use one gallon of joint compound for every 500 square feet of drywall. For tape, you will need approximately one roll of drywall tape for every 100 square feet of drywall.

Step 6: Consult with a Professional

Calculating drywall can be a daunting task, especially for those who are not familiar with the process. If you are unsure about any aspect of the calculation process, consult with a professional. They can provide valuable insight and ensure that you have the right amount of drywall for your project.
