How to Insert a Column Break
A column break places a hard break, much like a page break or section break, in the inserted location and forces the rest of the text to appear in the next column.
In a document that includes columns, place the cursor where you want the column to break. The best place for a column break is typically between paragraphs or other major sections of text. On the ribbon, go to the Layout tab and, in the Page Setup group, select Breaks > Column. The selected location now appears at the top of the next column.
Insert a Continuous Break
If you want columns to contain an even amount of text, use a continuous break, which evenly balances the text in the columns.
Place the cursor at the end of the column you want balanced. Go to the Layout tab and, in the Page Setup group, select Breaks > Continuous. The columns are now even.
Delete a Break
If there’s a break in a column that you no longer need, or if the document has a column break that you can’t find, delete the column break or continuous break.
Go to the Home tab and, in the Paragraph group, select Show Formatting Symbols. Formatting marks, including column breaks, appear. Place the cursor in the break you want to remove. Press Delete on the keyboard. The column break or continuous break is removed.
