How to Estimate Joint Compound and Tape

Estimating the amount of joint compound and drywall tape you need starts with finding the square footage. Different joint compound or mud products have different coverage levels, so it’s best to check the product you intend to use to verify the coverage.

If you’re using a lightweight joint compound (not premixed), then you’ll probably need 0.053 pounds of mud per square foot of drywall. If you’re using a quick-setting product, then you’ll likely need 0.073 pounds of mud per square foot. Drywall tape typically covers about 2-3 square feet of sheetrock per foot of tape.

How to Estimate Drywall Cost

To effectively estimate the cost of a drywall project, you need to calculate how many sheets you’ll be installing, the tape and joint compound required, and how many screws are necessary for the project.

The calculator above can estimate the material costs for the project, but every drywall project needs one critical component – a skilled laborer to install and finish the project.

The cost of labor varies drastically based on your geographic area and the skill of the craftsmen. We suggest getting several quotes in your area to get an accurate cost estimate for the project.

You can also use our drywall cost calculator to estimate the cost of the project in your area.

Bear in mind that more complex framing, layouts, or exclusions will require manual estimation of materials, any automated estimation will have a reduced level of accuracy as the complexity of the framing or exclusions rises.

Estimate Drywall Sheets

Calculate how many drywall sheets you will need by dividing the total square footage of area by 32 (if you’re using 4-by-8 sheets) or by 48 (if you’re using 4-by-12 sheets).

This division will get you the numbers of full sheets required. It’s a good idea to add 10 to 15 percent for waste and odd cuts. For example, if your total area is 1,600 square feet and you’re using 4-by-8 sheets: 

1,600 divided by 32 = 50 sheets
50 + 5 (10 percent add-on) = 55 sheets

If you want to get the cost, just multiply the total number of sheets by the price per sheet. Remember to add local taxes and delivery charges.

Estimate Drywall Tape

Using the total number of drywall sheets needed, multiply by the perimeter of each sheet to determine the linear feet of joint tape for the drywall. The perimeter of a 4-by-8 sheet is 16 feet; the perimeter of a 4-by-12 sheet is 20 feet. For example, if you need 55 4-by-8 sheets, the total tape needed is: 

55 x 16 = 800 feet

Most rolls of tape contain 500 feet, so divide your total by 500 to determine how many rolls tape you will need. Once that you know how many rolls of drywall tape is required, multiply by the cost per roll.
