Set paragraph margins in Pages on Mac
You can adjust the margins for a paragraph by indenting the entire paragraph, only the first line of a paragraph or all lines in a paragraph except the first line, creating a hanging indent. To set margins for the whole document, see Set document margins.
Change paragraph margins
Select one or more paragraphs, or press Command-A to select all paragraphs in the document.
Note: Your changes only apply to the paragraphs or text selected.
Do any of the following:
In the ruler, drag the margin marker (the orange triangle) to set a new margin.
In the Format
sidebar, click the Style button near the top, then click one of the default indent buttons in the Alignment section to increase or decrease the indent of an entire paragraph.
If the text is in a text box, table or shape, first click the Text tab at the top of the sidebar, then click the Layout button.
Note: For margins of less than 2.5 cm (1 inch), adjust the document margins in the Document sidebar (see Set document margins for a word processing document).
You can set the ruler to use points, inches or centimetres; to show the tick marks as percentages; and to place 0 (zero) at the centre of the ruler. See Change ruler units.
Indent the first line in a paragraph
You can indent the first line of text in a paragraph to create a visual break in the document that helps readers scan paragraphs.

In the ruler, drag the first line indent marker (the orange rectangle) to set a new indent.
The first line indent rectangle may be directly above the left margin triangle. If you can’t select just one of the markers, use the controls in the sidebar to set the margin and indent (see the option below).
