How do I find the square footage of my house from a floor plan?

Check the plan's scale against a printed dimension, measure the outside walls one level at a time, and add the levels together. Leave out the garage and porches, and count a basement separately. In FloorFigures, open the plan and press Shift+A to trace the building outline without the garage and porch; the total is rounded to the whole square foot.

Can I measure my floor plan from a photo?

Yes. Take the photo as straight-on as you can, open it in FloorFigures and use perspective correction: click the four corners of the plan sheet or any rectangle whose size you know. The photo is straightened and scaled in one step. On our angled test photo, rooms came out within 1–2% of the drawing.

What if I don't have a floor plan?

Start a blank sketch sheet and draw each room with the rectangle or polygon tool, typing in the wall lengths you measured with a tape. FloorFigures then works out the areas and materials the same way it does for a plan.

How many boxes of flooring do I need for a room?

Multiply the room's length by its width, add waste (about 10% for a straight lay, more for diagonal or herringbone), and divide by the square feet in one box, rounding up. A 12 x 14 room is 168 sq ft; with 10% waste that's 184.8 sq ft, or 10 boxes at 20 sq ft a box.

How much paint do I need for a room?

Multiply the room's perimeter by the ceiling height, subtract doors and windows, multiply by the number of coats, and divide by the coverage on the can, typically 350–400 sq ft per gallon. A 12 x 14 room with an 8 ft ceiling has 380 sq ft of wall after one door and one window; 2 coats at 350 sq ft per gallon is about 2.2 gallons for the walls.

Do I need to sign up or install anything?

No. FloorFigures runs in the browser on a computer, iPad or phone. There's no account, no trial and no limit on plans, and your plan is never uploaded.

How it works

From the plan in the drawer to a shopping list.

You start with

A floor plan, or a photo of one

You end with

A materials list and a budget for each room

01
Find your plan.
Look in your closing documents or builder paperwork, or save the floor plan from your home's old listing. No plan? Start a blank sketch and type in the wall lengths you measure with a tape.
02
Set the scale.
PDFs do it themselves. For a photo, click four corners of the sheet or a rectangle you know, or click both ends of any printed dimension and type it in.
03
Pick the rooms in your project.
Click inside each room you're redoing. If you're painting, set its ceiling height and the square feet of its doors and windows.
04
Read the shopping list.
The takeoff shows boxes, gallons, sheets and feet of baseboard per room, plus cost. Export a CSV for a spreadsheet or a PDF to take to the store.

Worked example

One bedroom, worked through.

A 12 x 14 bedroom with an 8 ft ceiling, one 3 x 7 door (21 sq ft) and one 3 x 5 window (15 sq ft), using FloorFigures' default settings.

Worked example: flooring, paint, drywall and baseboard for a 12 by 14 foot bedroom
Item	Math	Result
Floor area	12 × 14	168 sq ft
Flooring with 10% waste	168 × 1.10 = 184.8 sq ft, ÷ 20 sq ft a box	10 boxes
Wall area less openings	52 ft perimeter × 8 ft − 21 − 15	380 sq ft
Paint, walls and ceiling, 2 coats	(380 + 168) × 2 ÷ 350	3.1 gallons
Drywall, walls and ceiling, 10% waste	548 × 1.10 ÷ 32 sq ft a sheet	19 sheets (4x8)
Baseboard with 10% waste	52 × 1.10	57.2 ft

FloorFigures runs this for every room at once, straight from the plan. Change the waste, box size, coverage or coats to match your products and every number updates. It's free, with no account.
