Layout
Defines how many rows and columns of cards appear on a page.
Card margins
Card margins can be defined in millimeters. Remember that margins are applied to each card, not the whole page.
Font size
Font size settings are available for the issue's key, summary and the remaining text within the fields. Each field except issue key and summary will have the same font size. Note: this option works only for Simple Layout mode. When using Flexible Layout you can define font settings for each field separately.
Page size
Page size settings are only used for print preview and when generating PDF file (this feature is available only with Agile Cards for JIRA Server edition and not available for Cloud). The printout layout will be automatically adjusted to the page size chosen on the web browser's print page screen.
