Measuring Area

Calculate calibrated areas on PDF drawings using DraftPDF's polygon measurement tool.

The Area Measurement tool lets you trace a polygon and calculates its area in real-world units.

  1. Set the page scale first (see Setting a Drawing Scale).
  2. Select the Area Measurement tool.
  3. Click to place the first vertex of your polygon.
  4. Continue clicking to add vertices around the boundary.
  5. Double-click to close the polygon — the area is shown in the annotation label.
Tip:The measurement label shows both area and perimeter. You can reposition the label by dragging it after placement.
Warning:If the page scale changes later, use Set Scale and enable rescaling if you want existing measurement labels updated to the new calibration.
