When you click New (or CTRL + N) to open a new document in Word, it opens a copy of the default template Normal.dot saved in the Template folder. Word follows the naming convention Document1, Document2, etc. for a new document. The line and paragraph spacing in a new document is according to the Normal template. You can change these parameters though from the Styles gallery.
- On the Ribbon, under the tab Home, within the group Styles, click the dialog box launcher icon. Word opens the Styles dialog box. See below image.
- On the Styles dialog box, point to Normal and then click the down arrow button on the right. A drop-down menu appears
- From the drop-down menu, click Modify. The Modify Styles dialog box appears.
- From the Modify Style window, click the Format button (at the left bottom corner) and then select Paragraph. The Paragraph dialog box appears.
- From the Paragraph dialog box, under the section Spacing, select values in the fields Before and After to set spacing before and after a paragraph respectively.
- For line spacing, select Single from the drop-down list Line Spacing for a single spacing. Select Exactly to specific a value in the field At. See below image
