format:
  odt:
    page-width: 8.27
---

# Section 1

Same considerations hold for docx output format.

Start by rendering the supplied minimal example in both ODT and DOCX and trace the output-format handling. Done means page-width is honored so the generated documents use A4 rather than Letter, with coverage for both formats.
