You can format a document into two or more columns of text and graphics that flow automatically from one column to the next. You can change the number of columns for only a few paragraphs of your document, for a whole section, and for text in a text box or shape.
Note: If you don’t want the content in columns to flow from one column to the next, add a table with the number of columns you want to your document instead. That way, you can enter text across the page in individual table cells.
Do one of the following:
For the whole document: Click in any text in the document.
If the document has multiple sections, this only applies to the section you click in.
For specific paragraphs: Select the paragraphs you want to change.
For text in a text box or shape: Select the object.
Click the Layout button near the top of the sidebar on the right.
If you don’t see a sidebar, or the sidebar doesn’t have a Layout button, click
in the toolbar. If the text is in a text box, table, or shape, first click the Text tab at the top of the sidebar, then click the Layout button.
Use the controls in the Columns section to set the number of columns and their spacing:
Set the number of columns: Click the arrows next to the Columns value field.
Set column spacing: Double-click the values in the Column and Gutter columns then type the width for the column.
Set different column widths: Deselect the checkbox next to Equal column width.

If you added a table to your document and want to resize columns, see Resize table rows and columns for instructions.
Click where you want the previous column to end.
Click
in the toolbar, then choose Column Break.
When you insert a column break, Pages inserts a formatting character called an invisible. You can turn on invisibles in the document to see where special formatting is applied.
