Measure area on a PDF (square feet or m²)

Need the square footage of a room, roof plane or lot from a PDF? Draw around it and read the area — no download, no account, and the file stays on your computer.

How to measure area on a PDF

  1. Open your PDF in the FreeTakeoff app.
  2. Set the scale with a preset or by calibrating a known dimension.
  3. Choose Area and tap each corner of the shape. Tap the first point (or press Finish) to close it.
  4. The area appears in the shape and in the Quantities panel, in sq ft or m². Its perimeter is in the measurement CSV.

Irregular and L-shaped rooms

Area uses the exact polygon you draw (the shoelace formula), so L-shapes, angled walls and bay windows are handled. Draw several areas under one condition and they are added together.

Deducting openings

To subtract an island, stair opening or courtyard, create a second condition such as "Deductions" and measure it, then subtract the totals in your spreadsheet export.

Turn area into materials

Link the condition to FlooringCalc, TileMath, CarpetCalc, RoofMath or PaverCalc to convert square footage into boxes, bundles or pallets.

FAQ

Is my PDF uploaded?

Can I measure in square meters?

Yes. Switch units to metres at the top of the app; CSV exports always include both feet and metres.

Does it work on an iPad?

Yes. Tap to place points, drag with one finger to pan and pinch to zoom.
