Use grids to accurately line up text and objects in a document. When turned on, the grid is visible over the document. The Snap To Grid option aligns an object with the nearest grid line when you move the object.
-
To change the spacing between grid lines, enter a value for Width Between Lines and Height Between Lines.
To change the origin of the grid, enter a value for Grid Offset From Left Edge and Grid Offset From Top Edge.
To change the number of subdivisions within each grid square, enter a value for Subdivisions. Subdivision lines are lighter than grid lines.
To change the color of the grid lines, click the Grid Line Color square and choose a new color from the Color pop-up menu.
Horizontal and vertical rulers let you check the size of objects in your document. You can also create guides in your document, which are especially useful for lining up objects, such as form fields. You can change the unit of measurement and color used in the ruler.
Use the measuring tools to measure distances and areas of objects in PDF documents. The measuring tools are useful for showing the distances and areas associated with objects in a form or computer-aided design (CAD) drawing. You can also use these tools to measure certain areas of a document before sending it to a professional printer. The measuring tools are available to Acrobat Reader users only if the PDF creator enables measuring functionality.
When you use a measuring tool, the Measurement Info panel shows information about the measurement, such as current measurement, delta values, and scale ratio. Acrobat inserts comments with the values calculated for distance, perimeter, or area.

Select the Distance tool
to measure the distance between two points. Click the first point, move the pointer to the second point, and click again.Select the Perimeter tool
to measure a set of distances between multiple points. Click each point you want to measure. Then, double-click the last point. Select the Area tool
to measure the area within the line segments that you draw. Click each point you want to measure. After you have clicked at least two points, click the first point to complete the area measurement.

To snap the measurement to the end of a line, select Snap To Paths
.To snap the measurement to the endpoint of a line, select Snap To Endpoints
.To snap the measurement to the midpoint of a line, select Snap To Midpoints
.To snap the measurement to the intersection of multiple lines, select Snap To Intersections
To constrain the measurement lines to increments of 45º, hold down the Shift key.
To discontinue a measurement, right-click and choose Cancel Measurement.
To delete a measurement markup, click it with the Measurement Tool and press the Delete key.
To set measuring tool options, select the tool, then right-click anywhere in the PDF to view the options.
Change Scale Ratio
Change the scaling ratio (such as 3:2) and unit of measurement on the drawing areas.
Disable/Enable Measurement Markup
When enabled, the measurement lines you draw are added to the PDF. When disabled, the measurement lines disappear when you measure another object or select another tool.
Show/Hide Rulers
Show or hide vertical and horizontal rulers on the page. (Has the same effect as choosing View > Show/Hide > Rulers & Grids > Rulers.)
Export Measurement Markup To Excel
Save the information for all the measurements in your PDF to a CSV file.
Notă:
In Acrobat Reader, Measuring preferences apply to PDFs that have commenting enabled.
Use Scales And Units From Document (When Present)
When enabled, measurements based on the units generated from the original document, if present, are used. Deselect this option to specify the units of measurements manually.
Enable Measurement Markup
When enabled, the measurement lines you draw are added to the PDF. When disabled, the measurement lines disappear when you measure another object or select another tool. You can use the default measurement labels or specify your own label.
Use Default Leader Length (Distance Tool only)
When deselected, each time you draw a distance measurement, you move the mouse to determine the leader length.
Caption Style (Distance Tool only)
Specifies whether the distance measurement caption is Inside or on Top of the measurement line.
Default Leader Length (Distance Tool only)
Specifies the length of the line leader that appears on one side of the measurement points.
Default Leader Extension Above Line (Distance Tool only)
Specifies the length of the leader extension that appears above the measurement line.
Default Leader Offset From Line Points (Distance Tool only)
Specifies the amount of blank space that appears between the measurement points and the leader.
2D Snap Settings
Specify snap behavior. Sensitivity indicates how close the pointer must be to the item being snapped to. Snap Hint Color specifies the color of the snap line that appears when you hold the pointer over the object.
