A family of Microsoft word processing software products for creating web, email, and print documents.
In Word for Windows, you can modify the default settings for paragraph spacing via the Paragraph dialog box. Doing this will also update the Normal style.
A. On the Home tab, click the dialog launcher icon (circled in the screen shot below) in the Paragraph group.
B. Choose the desired settings for Spacing Before/After and Line Spacing.
C. Click Set as Default.
D. When prompted, choose "All documents based on the <template > template." Unless you are using a specific template, Word will save the changes to Normal.dotm which is the blank document template.
Changes apply to future documents that you base on the template.
