U.S. Supreme Court Fonts: Century Families and Booklet Documents

The U.S. Supreme Court’s rules adopted in February 2026 and effective in March 2026 specify Century-family type for booklet-format documents under Rule 33.1(b). Named examples include Century Expanded, New Century Schoolbook and Century Schoolbook. This is a document-preparation requirement; it is not an identification of every opinion, historical publication or page on the Court’s website.

The cited rule specifies 12-point booklet text with at least 2 points of leading and 10-point footnotes with at least 2 points of leading. Those details concern the stated booklet format. Read the full current rules for the relevant document category instead of transferring a remembered family name into another court’s template or another filing format.

If the task is identifying lettering in a published opinion, retain the exact document and date as the specimen. Compare its letter shapes and production context separately from the filing instructions. A rule governing documents submitted to a court does not itself prove how that court typesets its own output. Keep these two questions separate when explaining a font match to a colleague.

Record the exact selected family and style with the document template, alongside the applicable rule source. Compare body text, quotations and footnotes as separate roles rather than reducing every item to a single size. Preserve editable source material and a consistent export process. The legal-document guide discusses jurisdiction-specific rules more broadly, while the PDF-embedding and font-leading guides explain two relevant production concepts.
