- Open Theme Settings, then find the typography settings for the text role you are using, such as Lead Paragraph.
- If Responsive typography is enabled, lower Minimum Font Size to adjust smaller screens.
- Maximum Font Size controls the large-screen end of the responsive range, so it is not the first fix for a mobile-only problem.
- Preview the page at several mobile widths before publishing.
See the SW module documentation if your theme presents the typography controls differently.
