Setting the Grid Size
To set the grid size on a page:
Open the page in Edit Mode.
From the View menu, select Set Grid Size.
The Set Grid Size dialog box appears.
Enter a new number at Horizontal Grid Size.
Enter a new number at Vertical Grid Size.

Note
Changes will have no effect on the objects already on the page. It is however possible to align these objects to the new grid by repositioning them.
