Adding, Deleting and Moving Guides

Here are a few snippets of VBA you can use to modify guides in those versions of PowerPoint that support this sort of thing (2016 and possible 2013, not 2010 and earlier).

Note: all measurements are in Points. There are 72 points per inch.

Add Guides

Sub AddGuides()
    With ActivePresentation.Guides
        ' Add a vertical guide at 2" from left
        .Add ppVerticalGuide, 144
        ' Add a horizontal guide at 1" from left
        .Add ppHorizontalGuide, 72
    End With
End Sub

Move Guides

Sub MoveGuides()
    With ActivePresentation.Guides
        ' Move the second guide to 5" from left or top
        ' depending on whether it's vertical or horizontal
        .Item(2).Position = 5 * 72
    End With
End Sub

Delete Guides

Sub DeleteGuides()
    With ActivePresentation.Guides
        ' Delete the second guide
        .Item(2).Delete
    End With
End Sub
