Lay out a page by using columns

By default, Word creates text in a single column that runs from one margin to the other. You can format text in multiple columns, which are also known as "newspaper columns." Text usually fills columns in the order in which the columns appear, breaking from one column to another only after a column is filled. If you want more control over where columns break, you can manually insert a column break at a specific location, or adjust all columns to have equal lengths. When you use multiple columns, text flows continuously from the bottom of one column to the top of the next column.
