How to Change the Grid Spacing in PowerPoint
If you want to align objects easily using PowerPoint drawing guides and grids then you may choose to adjust the default grid spacing used by Microsoft PowerPoint
You can change the grid spacing options in the Grid and Guides settings dialog box under Grid settings group.
You may change the increments of grid measurements for even more precision when aligning objects including shapes or text boxes. This can help you to save time during the design process and achieve pixel perfect designs in PowerPoint. Moreover, this is the same technique used by SlideModel designers to adjust the objects in the slides.
In order to change the grid spacing options right click over the slide and then choose Grid Settings as shown in the figure below. You can also access this dialog box with settings from the Format menu and then choose Align menu and look for the Grid settings option.
Here you can specify the grid options, which are very useful for designers, for example you can check the Display smart guides when shapes are aligned or display drawing guides on the screen, but if you want to change a different grid spacing only then you can edit the Spacing value in inches and choose any other spacing value instead.
If you don’t want to see the guidelines then you can un-check the option under Format -> Align and then un-check View Guidelines.
Make sure the option Snap objects to grid is checked, too. This option is valid for PowerPoint 2010 but you can also find the spacing options in Microsoft PowerPoint 2013.
