Measure Tools let you calculate lengths and areas in your PDF document. You can measure real screen dimensions or specify a scale for use with scaled figures or drawings, such as architectural blueprints or maps.
To use Measure Tools
Select Tools > Measuring and choose Distance tool, Perimeter tool, or Area tool. This provides a drawing cursor and opens a dialog box that applies to all three tools. You can also access Measure Tools via the Measure toolbar, if displayed.
Choose the Distance tool to measure the distance between two points. First make desired settings in the Distance Tool dialog box. Then click on the start point, draw a line to the end point; click twice to complete the measurement.
Choose the Perimeter tool to calculate the perimeter of a closed polygon. Make desired settings in the Perimeter Tool dialog box. Then draw a line, lift the mouse, press it again to draw a connected line. Draw at least two connected lines, then double-click the end point of the second-to-last line to automatically close the polygon.
Choose the Perimeter tool to calculate the total length of a set of connected lines. Make desired settings in the Perimeter Tool dialog box. Then draw at least two connected lines and read the perimeter length at the current point next to the line or in the dialog box. Use a shortcut menu to complete the measurement with an open shape or double-click to form a closed polygon.
Choose the Area tool to calculate the area of a polygon. Make desired settings in the Area Tool dialog box. Then draw at least two connected lines, and double-click the end point of the second-to-last line to automatically close the polygon. Read the area in the dialog box or by hovering the cursor over the area icon.
Note:When drawing a polygon, no crossing lines are allowed.
To change the properties of an existing measurement, right-click on one of its lines.
The Markup panel of the dialog box lets you choose between a temporary or permanent display of measurements.
We also provide tools for measuring 3D objects.
