While many contractors find doing and completing drywall take-offs challenging. But how to do drywall takeoff and materials needed for a project is actually an easy task. Let’s find out how.
What is a drywall takeoff?
Drywall takeoff is the process of measuring and calculating the quantity of drywall materials needed for a construction project. This includes measuring the square footage of walls, ceilings, and other surfaces that will be covered in drywall. The takeoff data is then used to create an estimate for the project, which includes the cost of materials, labor, and other expenses.
How to prepare for a drywall takeoff?
To prepare for a drywall takeoff, you will need to:
Gather all of the necessary materials.
This includes the project blueprints, a tape measure, a calculator, and a notebook or spreadsheet to record your findings.
Review the blueprints carefully.
This will help you to understand the scope of the project and identify all of the areas where drywall will be installed.
Measure and record.
Measure and record the dimensions of each wall and ceiling. Be sure to measure the length, width, and height of each area, and round up to the nearest inch.
Calculate.
Calculate the square footage of each wall and ceiling. To do this, simply multiply the length by the width. If the wall or ceiling is not rectangular, you will need to break it down into smaller shapes and calculate the square footage of each shape individually.
Subtract.
Subtract the square footage of any openings, such as doors and windows. This will give you the net square footage of drywall that you will need.
Add a contingency factor of 5-10% to account for waste and cutting errors.
Drywall sheets quantity.
Calculate the number of drywall sheets required. To do this, divide the net square footage by the size of the drywall sheets that you will be using.
Additional tips:
Consistent measurements.
Use a consistent measurement method throughout the takeoff process. This will help to ensure accuracy.
If you are working with a complex project, consider using digital takeoff software. This can help to save time and improve accuracy.
Once you have completed the takeoff, double-check your calculations to make sure that they are correct.
Example:
Let’s say that you are preparing for a drywall takeoff for a new home. You have reviewed the blueprints and identified the following areas that will need drywall:
4 exterior walls, each measuring 10′ long by 8′ high
2 interior walls, each measuring 8′ long by 8′ high
1 ceiling, measuring 12′ long by 10′ wide
Step 1: Calculate the square footage of each wall and ceiling.
Exterior walls: 4 walls x 10′ long x 8′ high = 320 square feet
Interior walls: 2 walls x 8′ long x 8′ high = 128 square feet
Ceiling: 1 ceiling x 12′ long x 10′ wide = 120 square feet
Step 2: Subtract the square footage of any openings.
Assuming that there are no doors or windows in the exterior walls, the total square footage of drywall that you will need for the exterior walls is 320 square feet.
The interior walls have two doors, each measuring 3′ wide by 7′ high. The total square footage of drywall that you will need for the interior walls is 128 square feet – (2 doors x 3′ wide x 7′ high) = 112 square feet.
The ceiling has one light fixture, measuring 2′ wide by 2′ long. The total square footage of drywall that you will need for the ceiling is 120 square feet – (1 light fixture x 2′ wide x 2′ long) = 116 square feet.
Step 3: Add a contingency factor.
Assuming a contingency factor of 10%, you will need to add an additional 34.56 square feet of drywall to your total.
Step 4: Calculate the number of drywall sheets required.
Assuming that you are using standard 4′ x 8′ drywall sheets, you will need 17 sheets of drywall for the project.
Why is it important to do a drywall takeoff?
Drywall takeoff is important for a number of reasons, including:
Accurate estimation:
A drywall takeoff allows contractors to accurately estimate the amount of drywall and other materials needed for a project. This is essential for creating accurate and competitive bids, and for ensuring that the project is completed on time and within budget.
Reduced waste:
By accurately estimating the amount of drywall needed, contractors can reduce the amount of waste material. This saves money and is also good for the environment.

A drywall takeoff can help contractors to better plan and manage their projects. By knowing how much drywall and other materials are needed, and when they will be needed, contractors can avoid delays and disruptions.
Increased professionalism:
A drywall takeoff demonstrates to clients that the contractor is professional and organized. It also shows that the contractor has taken the time to thoroughly understand the project.
Competitive advantage:
Contractors who use drywall takeoffs are more likely to win bids and contracts. This is because they are able to provide more accurate and competitive estimates.
Below are some specific examples of how drywall takeoff can be used to benefit contractors and their clients:
A contractor can use drywall takeoff to estimate the cost of a new home construction project. This information can be used to create a detailed budget for the project and to ensure that the project is completed within budget.
A contractor can use drywall takeoff to estimate the cost of a drywall repair or renovation project. This information can be used to provide the client with a fair and accurate estimate of the cost of the project.
A contractor can use drywall takeoff to schedule the delivery of drywall materials to a project site. This helps to ensure that the materials are available when they are needed and that the project is not delayed.
A contractor can use drywall takeoff to track the progress of a project and to identify any potential problems early on. This helps to ensure that the project stays on track and that any problems are resolved quickly and efficiently.
Overall, drywall takeoff is an important tool for contractors of all sizes. It can be used to improve the accuracy of estimates, reduce waste, improve project management, increase professionalism, and gain a competitive advantage.
What are the different types of drywall takeoffs?
Mainly, There are two main types of drywall takeoffs:
Manual drywall takeoff:
This is the traditional method of takeoff, where a contractor or estimator will manually measure and calculate the amount of drywall needed for a project. This can be a time-consuming process, but it is often the most accurate method.
Digital drywall takeoff:
This method uses digital tools, such as takeoff software, to measure and calculate the amount of drywall needed for a project. This is a much faster and more efficient method than manual takeoff, but it is important to use accurate and up-to-date plans and software.
There are also a few specialized types of takeoffs, such as:
Acoustic drywall takeoff:
This type of takeoff takes into account the special needs of acoustic drywall, such as the need for thicker drywall and staggered joints.
Fire-rated drywall takeoff:
This type of takeoff takes into account the special needs of fire-rated drywall, such as the need for multiple layers of drywall and fire-resistant tape.
Water-resistant drywall takeoff:
Water-resistant takeoff takes into account the special needs of water-resistant drywall, such as the need for mold-resistant drywall and greenboard tape.
Tips for doing a drywall takeoff
There are tips for doing a drywall takeoff such as:
Gather all necessary information.
It consist of your plans and specifications, as well as any other information about the project that may be relevant, such as the type of drywall you will be using and the desired finish.
Measurements.
Measure the square footage of all surfaces that will be covered in drywall. This includes walls, ceilings, and any other areas. Be sure to measure the length and width of each surface, and then multiply those numbers together to get the square footage.
Account for openings.
This includes doors, windows, and any other openings in the walls. To do this, subtract the square footage of the openings from the total square footage of the walls.
Add a waste factor.
Drywall is a fragile material, and it is common to have some waste when cutting and installing it. A good rule of thumb is to add 10-15% to your total square footage to account for waste.
Calculate the number of sheets.
To do this, divide your total square footage by the square footage of a single sheet of drywall. Be sure to use the same size sheet of drywall that is specified in your plans and specifications.
Calculate material.
Estimate the number of other materials you will need. This includes corner beads, drywall tape, and joint compound. You can use a drywall takeoff calculator to help you with this.
Measure surfaces.
Be sure to measure all surfaces accurately. Even a small mistake can lead to a significant error in your takeoff.
When measuring openings, be sure to measure the opening itself, not the frame. This will ensure that you have enough drywall to cover the opening and the surrounding area.
If you are using different types of drywall in different areas of the project, be sure to calculate the takeoff for each type separately.
If you are unsure about anything, it is always best to err on the side of caution and order more drywall than you need. It is better to have too much drywall than not enough.
