Typography

UI font

Inter is used for the IDE user interface by default. The default font size is the same for all supported OS: 13.

Users can change the default font in Settings | Appearance. If the default font size is changed, other font sizes used in the UI are scaled respectively.

Use the built-in text styles from the table below whenever possible.

Font	Font size	Usage Examples
H1 `JBFont.h1().asBold()`	Default +5	Main page header. Example: Plugin name
H2 `JBFont.h2().asBold()`	Default +3	Small page header. Example: Headers in a plugin description
Default `JBFont.regular()`	Default	Main UI font. Examples: Labels, inputs, links, trees, tables, and other controls
Default semibold `JBFont.regular().asBold()`	Default	Header in dialogs, popups, notifications, tool windows, Got It tooltips
Paragraph	Default Line height default +3	Multiline description text
Medium `JBFont.medium()`	Default –1	Help text
Medium semibold `JBFont.medium().asBold()`	Default –1	Group headers in popups

If none of the built-in sizes work and a custom one is needed, define it as the default size +/- constant value. Do not hardcode font sizes.
