A family of Microsoft word processing software products for creating web, email, and print documents.
As Doug suggests, for more than one sheet of labels, a mail merge is the most efficient solution. For a single sheet, you can click New Document in the Labels dialog to get a sheet of labels that you can fill in. They're formatted as a table, so make sure you have table gridlines displayed so you can see the cell boundaries
This doesn't seem to work in Word for MAC 2016 version. When the label dialogue box is open you cannot call up a new document. The only way seems to be to choose the Mail Merge option. You then get a formatted table to fill in.
