Whenever you insert a graphic into a document, it is inserted in line with text by default. This treats the object as if it were text, moving it around the page as text is inserted. You can enable text wrapping on an object to move it around freely, forcing the text to move around to accommodate it.
You can use the Position menu to automatically place an object in a certain spot on the page.
Select the object.
Depending on the type of object selected, different ribbon groups will appear at the end of the ribbon. Selecting a picture will open the Picture Tools ribbon group, selecting a shape will open the Shape Tools ribbon group, and so on.
Each of these ribbon groups will include a Format tab.
Click the Format tab in the new ribbon group.
Click the Position button in the Arrange group.
This menu gives you the option to keep the object in line with text or position in one of nine automatic positions on the page.
Selecting one of these positions will force the text to wrap around the object automatically, instead of moving the object with it.
Select from the options.
The object is moved to the selected position.
You can also select More Layout Options to access the Layout dialog box, where you have more precise control over where the object appears on the page.
You can move objects on your own with a click and drag, but you can also make sure that they’re aligned with text and other objects using Word's alignment guides.
With the object selected, click the Align Objects button on the Format tab.
The Align Objects menu includes a Use Alignment Guides setting. If it’s already checked, the alignment guides are enabled.
If the Use Alignment Guides option is unchecked, select it.
Click and drag the object until green alignment guides appear.
These alignment guides will appear and disappear when the object is dragged near something that it can be aligned to.
To further help you with your alignment, you can also turn on gridlines that appear in the background like graph paper. Select View Gridlines from the Align Objects menu or check the Gridlines check box on the View tab.
