The snap feature means that when you move objects or placeholders of any kind, it may seem to “jump” as you move it.

You may have already used the grid without even realizing it because a feature called Snap objects to grid is turned on even if the grid is not displayed. When you enable gridlines in PowerPoint, a grid appears like graph paper lines on your slide with primary horizontal and vertical lines every inch with markers (dots) every 1/12 of an inch (if using inches as your unit of measure). As you move your mouse on the slide, you will see a dynamic marker or reference in the rulers, which can be helpful when moving objects. The rulers' measurements correspond with the dimensions set for the on-screen slide, which is a widescreen format by default. The center of the horizontal and vertical rulers are set at 0 (zero). Rulers display at the top and left of your Normal view of the slide. And so, you may want to start working first with one or two options, such as the Ruler and Gridlines.
