Before you begin
We're rolling out a new, more intuitive product experience. If the screen shown here doesn’t match your product interface, selecthelp for your current experience.
User grids
You can use grids to accurately line up text and objects in a document. When you enable Grids, it displays a framework of intersecting lines that helps you properly align various elements.
The Snap to Grid option aligns an object with the nearest grid line when you move the object.
To view or hide the grid, selectMenu> View>Show/Hide>Rulers & grids>Grid. A check mark appears next to the command name when the grid is displayed.
To turn the Snap to Grid option on or off,select> View>Show/Hide>Rulers & grids>Snap To grid.
To change the grid appearance
-
Select Menu > Preferences.
It opens the Preferences dialog.
-
Change grid settings as follows:
To change the spacing between grid lines, enter a value forWidth between linesandHeight between lines.
To change the origin of the grid, enter a value forGrid offset from left edgeandGrid offset from top edge.
To change the number of subdivisions within each grid square, enter a value forSubdivisions. Subdivision lines are lighter than grid lines.
To change the color of the grid lines, select Grid line colorsquare and choose a new color from the options.
Use rulers and guides
Horizontal and vertical rulers allow you to check the size of objects in your document. You can also create guides to easily line up objects, such as form fields. You can change the unit of measurement and color used in the ruler.
- To view rulers, selectMenu > View>Show/Hide>Rulers & grids>Rulers.
- To view or hide guides,selectMenu > View>Show/Hide>Rulers & grids>Guides.
To use rulers and guides
-
To create a horizontal guide, drag down from the horizontal ruler or double-click a location on the vertical ruler.
To create a vertical guide, drag right from the vertical ruler or double-click on a location on the horizontal ruler.
-
To move a guide, click the guide to select it, and then drag it to a new location.
-
To delete a guide, click the guide to select it and press the Delete key.
-
To delete all guides, right-click in the ruler area and select Clear All GuidesorClear Guides On Page.
-
To change guide colors, go to Menu > Preferences, and then from the left panel, select Units & guides. Then, select theGuide colorsquare and select a new color from the options.
Measure the height, width, or area of objects
You can use the 'Measure objects' 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 of computer-aided design (CAD) drawings. 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 Infopanel 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.
A. Measuring toolbarB. Objectbeing measuredC. MeasurementInfo panel
-
From the All tools menu, selectMeasure object.
It displays the Measure object toolset on the left panel.
-
From the Measure object menu on the left, selectMeasuring tool.
It displays the Measuring toolbar and the Measurement Info panel.
-
To measure areas of your PDF document, select any ofthe following measurement types:
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 that 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 that you want to measure. After you’ve clicked at least two points, click the first point to complete the area measurement.
-
While measuring objects, do any of the following:
To snap the measurement to the end of a line, selectSnap to Paths
To snap the measurement to the endpoint of a line, selectSnap to Endpoints
To snap the measurement to the midpoint of a line, selectSnap to Midpoints
To snap the measurement to the intersection of multiple lines, selectSnap to Intersections
To constrain the measurement lines to increments of 45º, hold down the Shift key.
To discontinue a measurement, right-click and chooseCancel Measurement.
To delete a measurement markup, click it with theMeasurement Tooland press the Delete key.
To set measuring tool options, select the tool, then right-click anywhere on the PDF. It displays the following options:
- Change Scale Ratio and Precision - To change the scaling ratio (such as 3:2) and unit of measurement on the drawing areas.
- Change Markup Label - To add or change the text that appears with the measurement.
- 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.
- Turn Ortho On/Off - When enabled, measurement lines are orthographic only.
- Show/Hide Rulers - Show or hide vertical and horizontal rulers on the page.
- Snap to Page Content/Don’t Snap to Page Content -Turn allSnap Enableson or off.
- Export Measurement Markup to Excel - Save the information for all the measurements in your PDF to a CSV file.
- Preferences - Open the Measurement (2D) preferences.
Set Measuring preferences
You can set the 2D Measuringpreferences to determine how 2D data is measured. To do so, go to > Preferences and then select Measuring (2D) from the left panel and then configure the following options:
- 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 measurement manually.
- Use Orthographic Lines - When enabled, measurement lines are orthographic only.
- Measuring Line Color - Specifies the color or the line that appears while drawing.
- 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.
- Default Line Start - Specifies the appearance of the starting line in distance measurements.
- Default Line End - Specifies the appearance of the ending line in distance measurements.
- 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. The sensitivity indicates how close the pointer must be to the item being snapped. SnapHint Colorspecifies the color of the snap line that appears when you hold the pointer over the object.
Note:
In Acrobat Reader, Measuring preferences apply to PDFs that have commenting enabled.
View cursor coordinates
The Cursor coordinates show the coordinate position of the pointer within the document pane. The position numbering begins in the upper-left corner of the document. Cursor coordinates also shows the width and height of a selected object as you resize it.
To view x and y coordinates:
-
Select Menu > View>Show/Hide>Cursor coordinates.
-
Move the pointer to view x and y coordinates.
To change the cursor coordinates measurement units:
-
SelectMenu > Preferences.
-
From the left panel in the Preferences dialog, select Unit & Guides.
-
Select the Page & ruler units drop down and then choose a different unit of measurement.
