Drywall Takeoff From a PDF: Walls, Ceilings, Board

To do a drywall takeoff from a PDF, set the scale on each page, measure partition lengths and ceiling areas, multiply lengths by height to get wall area, deduct large openings, add waste, and divide by the area of one sheet. A PDF takeoff tool such as Notch measures the lengths, areas and counts. The height, waste and sheet arithmetic happen in a spreadsheet after you export.

This guide uses a placeholder example so the arithmetic is easy to follow. None of the figures are typical values for a real project. Use your own heights, waste factor and supplier data.

What do you measure in a drywall takeoff?

A drywall takeoff has four kinds of quantity: wall board by area, ceiling board by area, trim and accessories by length or count, and finishing materials that follow the board area. Each is measured a different way on the page.

Before you measure, read the wall-type schedule, the partition types legend and the ceiling plans. A wall type tells you the height to take (to deck, to ceiling, or partial height), the number of layers on each face and whether the board is a special type such as moisture-resistant or fire-rated. Measure each wall type separately so the totals line up with how the board is priced.

How do you set up the PDF for a drywall takeoff?

Set the scale on every page you will measure, check it against a printed dimension, and keep one page per scale. Lengths and areas are only distances on the page until the scale is set.

1. Open the PDF in Notch and go to the first floor plan.
2. Click Set scale in the status strip.
3. Pick a preset under Architectural, Engineering or Metric, or choose Calibrate by drawing a line…, click both ends of a printed dimension and type its length.
4. Repeat on each page that has its own scale, including reflected ceiling plans and enlarged plans.
5. Measure a second printed dimension to confirm the scale before you take off anything.

The full method, including how to verify, is in How to Scale a PDF Drawing for Accurate Takeoffs. Scale is set per page in Notch, and presets assume the PDF was plotted at its stated sheet size, so calibrate from a dimension when you are unsure. Takeoff is part of the Solo and Pro plans, and both can be tried free for 14 days (see pricing).

How do you measure partitions and walls?

Trace each partition with the Linear tool, one measurement per wall type, then multiply the total length by the wall height in a spreadsheet. Notch gives you the length. It has no height field on a linear measurement, so wall area is a calculation you do after export.

1. Open the Measurements flyout on the tool rail and choose Linear, or press M.
2. Click New take-off in the Measurements panel so the tool is armed with Properties open. Name it for the wall type, for example "Type A, 1 layer each face".
3. Click the start of the partition and each corner along it. Snapping (under Snap in the status strip) pulls points onto the line work. Hold Ctrl (⌘ on Mac) to place a point without snapping.
4. Set the cost code and division in Properties if you use them.
5. Repeat for each wall type, giving each its own take-off name or layer.

Trace partitions at the centerline of the wall unless your method is to measure each face. Pick one method and use it on every sheet. Corners where two walls meet are counted twice or once depending on how you trace, which is a small difference per corner but adds up on a large job.

Openings in walls

Large openings reduce the board needed. Many estimators deduct openings only above a size they set themselves and treat the rest as waste, and that rule belongs in your estimate. To deduct, count the doors and windows with the Count tool, one count group per opening size, then multiply the count by each opening's area in the spreadsheet. A count group spans every page, so a door type tallies across all floors.

How do you measure ceilings?

Measure each ceiling with the Area tool and subtract openings with Cutout. Take ceilings from the reflected ceiling plan, since the architectural floor plan may not show drywall ceilings, soffits or bulkheads.

1. Choose Area from the Measurements flyout.
2. Click the corners of the ceiling region. It shades and shows its area in the calibrated unit.
3. For a shaft, skylight or large opening, choose Cutout and click its corners. The net area updates.
4. Name the take-off by ceiling type, because 5/8 in. type X board, moisture-resistant board and standard board are priced separately.
5. Measure soffits and bulkheads as Linear (length) with their height or girth in the spreadsheet, or as Area if the plan shows their extent.

How do you convert the quantities to sheets of drywall?

Divide the net board area by the area of one sheet, after adding your waste factor, and round up to whole sheets. Sheet area depends on the size: a 4 ft x 8 ft sheet is 32 sq ft, a 4 x 10 is 40 sq ft and a 4 x 12 is 48 sq ft.

Here is a placeholder example. These numbers are for the arithmetic only.

Waste depends on your layout, the sheet length you buy, your crew and the job, so use your own history. Longer sheets reduce butt joints on long walls but may not fit stairs or elevators. Compare the sheet counts for 8, 10 and 12 ft lengths against the wall heights on the job before you order.

How much tape, compound and screws does a drywall takeoff need?

Tape, compound and screws are priced by coverage per area of board, so take them from the manufacturer's published rate for the product you will use and the level of finish you are specifying. Use the manufacturer's data sheet for the exact product instead of a general rule, because rates differ between products and between sources.

One example from a manufacturer: USG's product FAQ says to expect approximately two 4.5 gallon pails of Sheetrock Brand UltraLightweight All Purpose Joint Compound to finish 1,000 sq ft of gypsum wallboard (USG FAQ, no date shown, checked November 2026). At that rate, the 10,580 sq ft in the example needs about 10.58 x 9 gallons, or roughly 95 gallons. Tape and screw rates vary by product and by spacing, so use the submittal sheet for the tape and the fastener spacing in your specification for the screws.

What level of finish are you pricing?

Compound quantity and labor both depend on the level of finish. The Gypsum Association's GA-214, Recommended Levels of Finish for Gypsum Panel Products (2021 edition, released in 2022), defines Levels 0 to 5. National Gypsum's summary of the standard (National Gypsum, August 2022) describes them like this:

The finish level is in the specification, usually Division 09 29 00. Read it before you price, since going from Level 4 to Level 5 adds a full skim coat over every surface.

How do you organize and export the drywall takeoff?

Group the measurements by wall type or cost code in the Measurements panel and export them as a CSV file. Then do the height, opening and waste arithmetic in a spreadsheet.

1. Open the Measurements panel in the right sidebar. It lists every measurement with live totals.
2. Open Group & sort and group by layer, name or cost code. Levels stack, so "cost code, then page" gives subtotals per floor.
3. Click Export CSV. For a custom layout, open the worksheet with Ctrl+Shift+L (⌘⇧L on Mac), add a Number custom column for wall height, and export the table.
4. In the spreadsheet, multiply each wall type's length by its height and faces, subtract openings, apply waste and divide by the sheet area.
5. Compare the spreadsheet's total length and area against the panel totals.

See the worksheet and measurements and calibration docs for every option. The general process, from the first sheet to the export, is in How to Do a Takeoff From a PDF, Step by Step.

How do you check a drywall takeoff?

Check the scale, the coverage of the plan and the arithmetic before the numbers go into a bid.

• [ ] Every measured page shows a scale that you checked against a second dimension.
• [ ] Each wall type in the schedule has a measurement, and its height matches the schedule or section.
• [ ] Ceiling areas come from the reflected ceiling plan, including soffits and bulkheads.
• [ ] Openings are deducted by your rule, and the rule is written down.
• [ ] The board type is split by use: standard, moisture-resistant, fire-rated and any special board.
• [ ] The level of finish matches the specification.
• [ ] A revised set was compared against the last one, and only changed walls were re-measured.

When an addendum or revision arrives, compare the two PDF drawings to see which partitions moved. Measurements in Notch are estimating aids that depend on calibration, and the contract documents govern.

Frequently asked questions

How do you calculate drywall sheets from plans?

Measure the partition lengths and ceiling areas, convert walls to area by multiplying length by height by the number of faces, subtract large openings, add waste and divide by the area of one sheet. A 4 x 8 sheet covers 32 sq ft. Round up to whole sheets.

Can you do a drywall takeoff from a PDF?

Yes. Set the scale on the page, then measure walls with a linear tool and ceilings with an area tool. Count doors and windows if you deduct them. Export the quantities and finish the height, waste and sheet arithmetic in a spreadsheet.

What waste factor should you use on drywall?

Use the factor from your own jobs. Waste depends on the layout, the sheet length, the number of small rooms and the crew, so no single number fits every project. Record the waste on completed jobs and apply that to the next bid.

How much joint compound does 1,000 sq ft of drywall need?

It depends on the product and the finish level. USG's FAQ says about two 4.5 gallon pails of its UltraLightweight All Purpose Joint Compound finish 1,000 sq ft of wallboard. Check the data sheet for the compound in your specification.
