When you want to make sure everything on a Word page lines up properly, display the gridlines.
To do this, first display the Drawing toolbar then choose Draw, Grid and choose the Display gridlines on screen checkbox. Set the Use Margins option to start the grid aligned on the left and top margins. Set the value to 1 for small squares and to 2 or 3 for a larger grid.
If you select the Snap Objects to Grid checkbox all objects will automatically line up against the grid.
If you don’t want this to be the case, press the Alt key as you drag an object and it will be freed from snapping to align to the grid.
