How to Do a Material Takeoff From Floor Plans
A step-by-step residential takeoff from a floor plan: floor area, wall area, perimeter, then flooring, paint, drywall and trim, with a template.

Short answer
A material takeoff lists the quantities a job needs, measured from the plans. For residential interiors, measure each room's floor area, perimeter and ceiling height, then derive wall area (perimeter × height − openings) and ceiling area, and convert: flooring = floor area + waste ÷ box size, paint = wall area × coats ÷ 350 sq ft per gallon, drywall = walls + ceiling + waste ÷ 32 sq ft per 4×8 sheet.
Most of a residential interior job comes from three measurements per room. Get those right from the floor plan and flooring, paint, drywall and trim all follow from simple arithmetic. Here's the process, a template you can copy, and a worked example for a small house.
What is a material takeoff?
A takeoff is the quantity side of an estimate: how many square feet, gallons, sheets, linear feet and pieces the job needs. It carries no prices. An estimate multiplies each quantity by a unit price and adds labor and the items a plan doesn't show (see estimating a remodel from a floor plan). Commercial takeoffs cover every trade across a full plan set. A residential interior takeoff is smaller: rooms, walls, ceilings, openings and a few counts.
Is the plan's scale right?
Check it before you measure anything. A PDF that was printed or saved "fit to page" no longer matches its scale note, and every quantity will be off by the same factor. Measure a printed dimension (a long wall is best) and confirm it reads true. If it doesn't, set the scale from the dimension, not the note. More in how to scale a PDF drawing.
How to do a takeoff, step by step
- 1
Check the scale
Measure a printed dimension and confirm it reads true before measuring anything else. - 2
Measure each room
Floor area (length × width, split into rectangles if needed) and perimeter (the sum of the wall lengths). - 3
Note ceiling heights and openings
Each room's ceiling height, and the doors and windows in its walls with their sizes. The plan's door and window schedules help. - 4
Derive wall and ceiling area
Walls = perimeter × height − openings. A flat ceiling = floor area. - 5
Convert to materials
Apply waste, coverage and unit sizes to get boxes, gallons, sheets and lengths. - 6
Total and round up
Add the rooms and round each material up to whole units. Keep the room-by-room sheet with the order.
What quantities come off a floor plan?
| Quantity | How to get it | Unit | Feeds |
|---|---|---|---|
| Floor area | Length × width per room | sq ft | Flooring, underlayment, floor prep |
| Perimeter | Sum of the wall lengths | ft | Baseboard, wall area |
| Wall area | Perimeter × ceiling height − openings | sq ft | Paint, drywall, wall tile |
| Ceiling area | Same as floor area if flat; along the slope if not | sq ft | Ceiling paint, drywall |
| Openings | Width × height of each door and window | sq ft and count | Wall deductions, casing, transitions |
| Counts | Doors, windows, fixtures, from symbols and schedules | each | Hardware, trim kits, fixtures |
How do quantities become materials?
| Material | Formula | Usual allowance |
|---|---|---|
| Flooring | Floor area × (1 + waste) ÷ box coverage | 10% straight, 15% diagonal; box size from the label |
| Paint | (Walls + ceilings) × coats ÷ coverage | 2 coats; 350–400 sq ft per gallon (Sherwin-Williams) |
| Primer | Area ÷ coverage | 200–300 sq ft per gallon (Sherwin-Williams) |
| Drywall | (Walls + ceiling) × (1 + waste) ÷ sheet area | 10–15% waste; 32 sq ft per 4×8 sheet |
| Baseboard | (Perimeter − about 3 ft per door) × (1 + waste) | A common method; 5–10% waste |
Each material has its own guide: flooring, paint and drywall.
A takeoff template, filled in
One row per room. This small single-story house has 8 ft ceilings, doors at 21 sq ft and windows at 15 sq ft:
| Room | Floor | Perimeter | Height | Doors / windows | Walls (net) | Ceiling |
|---|---|---|---|---|---|---|
| Living room, 16' × 14' | 224 sq ft | 60 ft | 8 ft | 2 / 2 | 408 sq ft | 224 sq ft |
| Kitchen, 12' × 10' | 120 sq ft | 44 ft | 8 ft | 1 / 1 | 316 sq ft | 120 sq ft |
| Bedroom 1, 12' × 12' | 144 sq ft | 48 ft | 8 ft | 2 / 2 | 312 sq ft | 144 sq ft |
| Bedroom 2, 11' × 10' | 110 sq ft | 42 ft | 8 ft | 2 / 1 | 279 sq ft | 110 sq ft |
| Bathroom, 8' × 5' | 40 sq ft | 26 ft | 8 ft | 1 / 1 | 172 sq ft | 40 sq ft |
| Hall, 10' × 3' 6" | 35 sq ft | 27 ft | 8 ft | 4 / 0 | 132 sq ft | 35 sq ft |
| Total | 673 sq ft | 247 ft | 12 / 7 | 1,619 sq ft | 673 sq ft |
Then the materials, rounded up to what you can buy:
| Material | Math | Order |
|---|---|---|
| Flooring (20 sq ft boxes, 10% waste) | 673 × 1.10 = 740.3 sq ft; ÷ 20 = 37.0 | 38 boxes |
| Paint, walls and ceilings, 2 coats | (1,619 + 673) × 2 ÷ 350 = 13.1 | 14 gallons |
| Drywall, 4×8, 10% waste | (1,619 + 673) × 1.10 ÷ 32 = 78.8 | 79 sheets |
| Baseboard, 10% waste | (247 − 12 × 3) × 1.10 = 232.1 | 233 linear ft |
Two notes. Door counts are per room, so a door between two rooms appears twice; that's right for paint and baseboard, which run on both sides. And drywall here deducts doors and windows; if you'll hang board over the windows and cut them out, add them back (83 sheets) or raise the waste (see the drywall guide). In a kitchen, also take baseboard off where cabinets run along the wall.
Doing the takeoff in FloorFigures
FloorFigures is a free, browser-based tool that does the measuring half of this from the plan. Nothing is uploaded and there's no account.
- Open the plan: a PDF, an image or a photo. PDFs keep their vector lines, so measurements snap to the actual wall lines.
- Check the scale: on PDFs it sets the scale from the printed dimensions and warns when the scale note disagrees. Measure a second dimension on the Scale tab to see the error.
- Find the rooms: press A to find every room, or click inside one to trace it to the wall faces.
- Set heights and openings: in each room's details, enter its ceiling height and the area of its openings.
- Read the Takeoff tab: per room, floor area, perimeter, wall area less openings, ceiling area, flooring with waste and boxes, paint gallons, drywall sheets, baseboard and a cost from your price list. Defaults are 10% waste, 20 sq ft boxes, 350 sq ft per gallon, 2 coats, 4×8 sheets and 8 ft ceilings; change any of them.
- Export: a CSV with one row per room and the totals, or a PDF report with the plan, the scale check and the takeoff.
Counts (doors, windows, fixtures) are tallied by hand; FloorFigures measures areas and lengths.
FloorFigures or desktop takeoff software?

Questions
- What is a material takeoff?
- A material takeoff is a list of the quantities of each material a job needs, measured from the plans: square feet of flooring, gallons of paint, sheets of drywall, linear feet of baseboard, counts of doors and fixtures. It has no prices; an estimate applies prices to the takeoff.
- What's the difference between a takeoff and an estimate?
- A takeoff says how much: quantities measured from the plans. An estimate says how much it costs: each quantity multiplied by a unit price, plus labor, items the plans don't show, and a contingency. The takeoff comes first, and the estimate is only as good as the quantities under it.
- How do you do a drywall takeoff from plans?
- For each room, multiply the perimeter by the ceiling height to get wall area and add the ceiling area (length × width for a flat ceiling). Add the rooms, add 10–15% for waste and divide by the sheet size: 32 sq ft for 4x8, 48 for 4x12. Round up to whole sheets.
- How do you do a painting takeoff from blueprints?
- Measure each room's perimeter from the plan, multiply by the ceiling height and subtract doors and windows to get the wall area. Add ceilings if they're in scope. Multiply by the number of coats (usually 2) and divide by the coverage per gallon, about 350–400 sq ft according to Sherwin-Williams.
- How do you estimate flooring from a blueprint?
- Measure the floor area of each room the flooring covers, including closets and halls, and add a waste allowance: about 10% for a straight lay, 15% for diagonal, 15–20% for herringbone. Divide by the coverage per box from the product label and round up to whole boxes.
- Is there free takeoff software for residential work?
- Yes. FloorFigures is free with no limits: it opens PDF or image floor plans in the browser, measures every room, and gives a per-room takeoff of floor area, perimeter, wall and ceiling area, flooring boxes, paint gallons, drywall sheets and baseboard, with CSV export. Desktop takeoff programs cover more trades and commercial plan sets but are typically paid.
