If you have tried to move a control by using your mouse, you have no doubt become a little frustrated trying to get everything lined up neatly. Fortunately, Access gives you the ability to use the grid layout that is visible in Form Design view:

 

 

The solid black lines are defined as a 1” grid. You can modify the resolution of the dot matrix visible in Design view. To modify this setting, open the Properties for the form or double-click the form selector button in Design view:

 

 

Click the Format tab in the Properties window and scroll down until you can see the Grid X and Grid Y properties:

 

 

The numbers in each field denote how much you can subdivide the 1” square grid visible in Design view. The default value is 24, meaning that the space between the dots is 1/24^th of an inch. You can adjust these properties from 1 to 64. Both values can be adjusted independently, though it is a good idea to keep both values either the same or multiples of each other.

Changing the values to 12 for each field decreases the resolution by ½:

 

 

If you want to turn off the gridlines completely, click View à Grid to uncheck the option.
