Measure an area of a polygon

  1. Measure icon Select the Measure tools at Edit > Tools > Measuring and then select the Area tool in the drop-down.

    The Area Tool floating window appears.

  2. Optionally, update settings (such as measurement units, scale ratio, and snap) as preferred in the Area Tool floating window.
  3. Select the starting corner of the polygon and click on it as close you can (release the mouse button when clicked).

    Power PDF displays a measurement polygon.

  4. Go around following the polygon precisely and click on each corner.

    • When drawing a polygon, no crossing lines are allowed.

    • Select Complete Measurement in the context menu to discontinue the measurement process. (You need to have two or more corners already pointed.) The polygon is closed automatically and the Area Tool floating window preserves the values of the last measurement.

  6. Click on the View tab of the Area Tool floating window and read measurement values and cursor location.
