When you create mailing labels in Microsoft Word, you may find that the text for the Address block ends up with double spacing. To get round this, before starting your labels, go to the Home tab and in the Styles group, choose the No Spacing style. This will ensure single spacing between the lines of the address.
If you find you cannot see lines to see where each label will start and finish, go to the Table Tools Layout tab, and in the Table group, select View – Gridlines.
If you want the address to move down slightly on the label, go to the beginning of the address and press the Spacebar and then press Enter. This will give more space at the top of the address.
Remember to press Update Labels to ensure you get multiple labels on one page!
