How to print a PDF as a poster?
Use the Poster option in Adobe Acrobat to divide one large PDF page across several sheets that can be trimmed and joined.
Tile the PDF across multiple sheets
- Open the PDF in Adobe Acrobat or Acrobat Reader and select Print.
- Under Page Sizing & Handling, select Poster.
- Adjust Tile Scale and Overlap, then enable cut marks if they will help with assembly.
- Review the sheet layout in the preview before printing.
- Trim the overlap, align the sheets, and tape them together from the back.
For a calendar poster
Start with a high-resolution PDF and run a small test before printing every tile. A modest overlap makes adjoining dates and grid lines easier to align.
