How to Print Sudoku Puzzles
Each PDF is sized for US Letter paper (8.5 × 11 inches) in portrait orientation. For the best results:
- Paper size: Letter works out of the box. On A4, enable "Fit to page" in your print dialog.
- Orientation: Portrait. One puzzle fills each page for easy solving with a pen or pencil.
- Save ink: The grids use thin gray cell lines and black digits — already ink-light. Choose "Black & white" or "Grayscale" to save even more.
- Margins: Use your printer's default margins; the layout leaves plenty of white space.
