Area Tool

Area Tool icon

Select Edit > Tools > Measure > Distance Tool to open the Area Tool floating window. First select options in the Settings and Markup panels, and then draw a set of lines line over a PDF object whose area you want to measure. Click to change line direction and double-click to close the shape. See Measure an area of a polygon for details.

View tab

The View tab displays the current value of the measurement and the cursor location.


  • Distance: As you draw the current section of a set of lines, the length is displayed dynamically.

  • Angle: Shows the angle of the first line section related to the X axis; for subsequent line sections, it shows the angle relative to the previous section. No signs or directions of rotation are considered.

  • Area: The area of the polygon is displayed when the drawing is completed.

Cursor Location:

  • X: The X coordinate of the cursor position relative to the top left page corner.

  • Y: The Y coordinate of the cursor position relative to the top left page corner.

No signs are considered.

Markup tab

Use the Markup tab settings to preserve measurement values in comments.

  • Use Markup: Store the current and future measurements with your PDF document; otherwise, all results are discarded as soon as you start a new measurement. In the text field, type the text to display in a pop-up comment window when you hover the cursor over any line in the shape.

  • Measuring Color: Set the color for measuring lines.
