Once you’ve inserted objects into your documents, they will usually need to be modified in order to fit with the other elements on a page. You can resize, move, rotate, and delete the shapes and graphics in your documents.
You can resize an object that you’ve inserted to make it fit wherever you need it.
Select the object.
Notice that when you select an object, sizing handles appear at the sides and corners of the border.
Click and drag the sizing handles until the object is the size you want.
Pictures and screenshots will automatically maintain their proportions if you click and drag from the corners. To maintain other objects’ proportions while resizing, hold down the Shift key as you click and drag.
You can only click and drag objects to move them if they’re not positioned in line with the text. Click the Layout tab, then click the Wrap Text button and select another option in order to position the object freely.
