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 Edit > Tools > Measuring and choose Distance tool, Perimeter tool, or Area tool from the drop-down list. This provides a drawing cursor and opens a dialog box that applies to all three tools.
View panel: This displays measurement results dynamically as you move the cursor.
Settings panel: Set the scale and measurement unit to be used, snap settings and more.
Markup panel: Enable or disable placement of the measurement result into a note linked to the measured object. This allows the result to be copied and pasted to other applications. In other words, you choose between a temporary or permanent display of measurements.
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 forming an open shape. 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. Click to confirm the last drawn line, then right-click for a shortcut menu and choose Complete Measurement.
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.
Notes
To change the properties of an existing measurement, right-click on one of its lines.
We also provide tools for measuring 3D objects.
