How Much Drywall Mud Need per Sheet? Easy Way to Calculate

Drywall installation is a common task in home renovations and construction projects. One of the key aspects of drywall installation is the application of drywall mud, also known as joint compound. This article provides a comprehensive guide on how to calculate the amount of drywall mud needed per sheet, making the process easier and more efficient for homeowners and contractors alike.

Understanding Drywall Mud

Drywall mud is a material used to fill and smooth out the joints between drywall sheets, cover nail or screw heads, and correct any imperfections on the drywall surface. It comes in different types, including setting type compound, regular premixed compound, and topping compound, each with its own specific uses and characteristics.

Calculating the Amount of Drywall Mud Needed

The right amount of joint compound is a very important factor for drywall finishing. But the question is, how much drywall mud needs a par sheet? In the market, there are different sizes of drywall sheets, and each sheet size can be 26 to 66 square feet. Also, there have different types of joint compounds. Each sheet and compound type make the amount different. For example, a 4’X8′ sheet can need an estimated 0.760 Kg setting compound, 0.319 gallon premixed compound. And sheet size makes the amount different.

Here is a recommended estimate idea for your drywall mud project. We’ve included the setting type of compound, regular premixed compound, and skim coat compound.

Drywall Sheet Size Setting type compound Regular premix compound Premixed compound for skim coat
4 Inch X 8 Inch 0.760 KG 0.319 Gallon 0.319 Gallon
4 Inch X 9 Inch 0.858 Kg 0.357 Gallon 0.357 Gallon
58 Feet X 8 Inch 0.896 KG 0.475 Gallon 0.475 Gallon
4 Inch X 10 Inch 0.943 KG 0.394 Gallon 0.394 Gallon
58 Feet X 9 Inch 0.943 KG 0.394 Gallon 0.394 Gallon
4 Inch X 11 Inch 1.028 KG 0.428 Gallon 0.428 Gallon
54 Feet X 10 Inch 1.054 KG 0.441 Gallon 0.441 Gallon
4 Inch X 12 Inch 1.120 KG 0.469 Gallon 0.469 Gallon
4 Inch X 13 Feet 1.235 KG 0.517 Gallon 0.517 Gallon
54 Feet X 12 Inch 1.279 KG 0.536 Gallon 0.536 Gallon
4 Inch X 14 Inch 1.327 KG 0.555 Gallon 0.555 Gallon
4 Inch X 15 Inch 1.433 KG 0.600 Gallon 0.600 Gallon
4 Inch X 16 Inch 1.493 KG 0.625 Gallon 0.625 Gallon

Easy Way to Calculate Drywall Mud for Your Project

  1. Remember how many sheets you use on drywall.
  2. Then choose your sheet from the table above.
  3. Now multiply your sheets with the mud amount which is already shared above.
  4. Repeat this process for all types of joint compounds.
  5. Now you can get an idea of how many setting compounds, premixed compounds, and skim coat mud you need for your project.

Calculating the Amount of Drywall Mud Needed

Step 1: Measure the Total Square Footage

The first step in calculating the amount of drywall mud needed is to measure the total square footage of the areas where the drywall will be installed. This can be done by multiplying the width times the height of each wall or ceiling area, then adding all of the quantities together to get a total square-foot amount.

Step 2: Estimate the Number of Drywall Sheets

Next, calculate how many drywall sheets you will need by dividing the total square footage of the 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 give you the number of full sheets required. It’s a good idea to add 10 to 15 percent for waste and odd cuts.

Step 3: Calculate the Amount of Joint Compound

As a general rule, estimate 0.053 pounds of mud per square foot of drywall. So, multiply the total number of square feet by 0.053 to determine how many pounds of compound you’ll need. For example, if you are putting up 1,600 square feet of drywall, you would need approximately 85 pounds of compound.

Other Materials Needed for Drywall Installation

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.

Drywall Screws

To determine the pounds of screws required, divide the square footage of drywall by 300. For example, if you have 1,600 square feet of drywall, you would need approximately 5.33 pounds of screws.

Corner Beads

For corner beads, count the number of outside wall corners in the entire job. Plan on using one full corner bead for each corner, using either 8-foot or 10-foot bead.

Considerations for Drywall Mud Calculation

While the above steps provide a general guide, it’s important to consider a few factors that can affect the amount of drywall mud needed. These include the type of drywall mud used, the skill level of the person applying the mud, and the desired finish quality.


This is an estimate idea. You can need some extra or less amount compound for your project. However, the difference cannot be big. You should not use high or less amounts of mud because it causes mud peeling. We hope you got your answer, if you think this article is helpful please share it with your friends and family.
