Balance newsletter-style column length on a page

Two columns of unequal text balanced into two columns of more equally distributed text

In print layout view, click at the end of the columns you want to balance.
On the Insert menu, click Break.
Click Continuous.
Microsoft Word inserts a continuous section break, which balances the text equally among the columns.

If you want to force a new page to start after the balanced columns, click after the continuous section break, and then insert a manual page break.
