The default auto-leading option sets the leading at 120% of the type size (for example, 12-point leading for 10-point
type). When auto-leading is in use, InDesign displays the leading value in parentheses in the Leading menu of the
Character panel.
A Leading B Text height C Larger text size of one word increases leading for that one line.
Change leading
By default, leading is a character attribute, which means that you can apply more than one leading value within the same
paragraph. The largest leading value in a line of type determines the leading for that line. However, you can select a
preferences option so that leading applies to the entire paragraph, instead of to text within a paragraph. This setting
does not affect the leading in existing frames.
Change leading of selected text
1 Select the text you want to change.
2 Do any of the following:
• In the Character panel or Control panel, choose the leading you want from the Leading menu .
• Select the existing leading value and type a new value.
• While creating a paragraph style, change the leading using the Basic Character Formats panel.
If InDesign ignores the leading change, it may be due to Vertical Justification or Align To Baseline Grid being selected.
Choose Object > Text Frame Options and make sure Vertical Justification is set to Top, and make sure Do Not Align
To Baseline Grid is selected in the Paragraph panel, Control panel, or paragraph style.
You can also adjust vertical space by aligning text to the baseline grid. When baseline grid is set, the baseline grid setting
takes precedence over the leading value.
Change the default leading percentage
1 Select the paragraphs that you want to change.
2 Choose Justification from the Paragraph panel menu or from the Control panel menu.
3 For Auto Leading, specify a new default percentage. The minimum value is 0%, and the maximum value is 500%.
Note: The Auto option in the Leading pop-up menu of the Control panel menu sets Auto Leading value in the Justification
dialog box as a ratio (%) of character size. The default is 175% for text frames and 100% for frame grids.
Apply leading to whole paragraphs
1 Choose Edit > Preferences > Type (Windows) or InDesign > Preferences > Type (Mac OS).
2 Select Apply Leading To Entire Paragraph, and then click OK.
Note: When you use a character style to apply leading to text, the leading affects only the text to which the style is applied,
not the entire paragraph, regardless of whether the Apply Leading To Entire Paragraph option is selected.
