Fill in the blank: Google recommends a font size of at least _______ on at least 60% of the text on your page.

This value matches HubSpot’s mobile readability guidance for SEO recommendations and page auditing. The purpose of that threshold is to keep body copy legible on smaller screens without forcing visitors to zoom. In HubSpot terminology, this belongs to the Mobile Experience side of optimization rather than performance metrics such as Largest Contentful Paint or Cumulative Layout Shift . The larger values listed are stricter than the baseline guidance, while the smaller threshold is the minimum benchmark used for acceptable readability. This is about text legibility across the page, not about headings, branding, or typography preference.
