Using the layout grid in repositioning graphics

Acrobat has a layout grid that you can use to help you in repositioning graphic images. To turn on the display of the layout grid in the PDF document, choose View➪Grid or press Ctrl+U (Ô+U on the Mac). When working with the layout grid, you can modify the default grid settings in the Units & Guides section of the Preferences dialog box by pressing Ctrl+K (Ô+K on the Mac) and then clicking Units and Guides in the list box on the left. The Layout Grid section of the dialog box contains a number of grid options that you can change:

• By default, Acrobat subdivides each of the major grid squares into three divisions across and three down, making a total of nine little subdivisions. To increase the number of squares in each of the major grid squares, increase the value in the Subdivisions text box.
  
• To offset the layout grid in relation to the top and left margin of the page, enter a value in the Grid Offset from Left Edge and the Grid Offset from Top Edge text boxes.
• By default, Acrobat makes each major grid square one-inch square with one inch between their vertical lines and one inch between their horizontal lines. To make the major grid squares larger so that there are fewer, farther apart, increase the values in the Width Between Lines and Height Between Lines text boxes. To make the grid squares smaller so that there are more, closer together, decrease the values in these text boxes. Note, however, that if you decrease the values in these text boxes too much, Acrobat is no longer able to subdivide the square using the value entered in the Subdivisions text box.
• By default, Acrobat colors the lines in the layout grid blue. To select a new color for all grid lines, click the Grid Line Color button and then click the desired color in the color palette.
