When does this happen?

IF docx-js defaults page size to A4, causing mismatch for US Letter documents.

How others solved it

THEN Always explicitly set page size in section properties using DXA units: width=12240, height=15840, and 1-inch margins (1440 DXA) for US Letter. For landscape, pass short edge as width, long as height, and set orientation to PageOrientation.LANDSCAPE.

sections: [{
  properties: {
    page: {
      size: { width: 12240, height: 15840 },
      margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 }
    }
  },
  children: []
}]
