When working with the word document, you may need to increase indents for one or more paragraphs from both sides so the paragraph will stay in the middle. Please see below for details:
Step 1: Select the paragraph or paragraphs;
Step 2: Click the "Home" tab from the ribbon (or the "Layout" tab);
Step 3: Click the right-bottom corner in the "Paragraph" section;
Step 4: Under "Indentation" section in the "Paragraph" window, type the numbers for inside and outside indentation;
Step 5: Click "OK" to finish.
If you only want to increase indent only for the first line in each paragraph, please check how to indent the first line of each paragraph.
