To put a blank page into your Word document, place the cursor where you want the new page to begin and then select Insert > Blank Page. The blank page opens, ready for whatever you want to add. 

Another option when you need a little space is to insert a page break. The difference is that Insert > Blank Page puts an entire blank page into your document, whereas Insert > Page Break simply pushes whatever comes after the break to the top of the next page. To learn more, see Add a page break.

To remove a blank page from your document, see Delete a blank page.
