Print and assemble a tiled PDF

1. Choose the page to print

Open a PDF in the tiling tool and choose a source page. Each download contains tiles for that one page. For a document with several large pages, select and download them separately.

Use Full poster to inspect the complete page and its sheet grid. Print sheet shows the actual contents of one output sheet, including the cut guides. Part of an image continuing beyond a sheet edge is expected: the neighboring sheet carries the next section.

The sample is an 18 × 24 inch alignment pattern. Its original-size grid squares measure one inch; they scale along with the rest of the sample if you change the finished size.

2. Set the finished size and paper

• Original: keep the PDF page's recorded physical dimensions. Check the width and height shown; a file's name or screen appearance does not establish its print size.
• Custom: enter either width or height in inches. PDF to Letters changes the other dimension proportionally. For example, changing an 18 × 24 inch page to 12 inches wide makes it 16 inches high.
• Rotation: rotate the source page clockwise when needed. Rotation changes which edge is treated as the width.
• Orientation: choose portrait or landscape Letter paper. Auto compares both and selects the one needing fewer sheets; a tie uses portrait.
• Printer margin: reserve an unprinted border your printer can handle. Increase it if a test page loses marks at the edges.
• Overlap: repeat a strip of artwork between neighboring sheets. The default is 0.25 inch. This provides room to align sheets and does not enlarge the finished poster.

Cut and alignment guides need their own gutters and instruction space. Turning them on can increase the sheet count, but does not shrink the artwork. Check the final sheet count after changing any setting.

3. Check scale before a full print

1. In the tool, select Calibration sheet and open the downloaded PDF in a PDF viewer.
2. Choose US Letter paper, single-sided printing and Actual size or 100%. Turn off Fit, Shrink and borderless expansion. Use one PDF page per physical sheet; the PDF is already tiled.
3. Print the test and measure the one-inch square and five-inch line with a ruler.
4. If either measurement is wrong, check scaling in both the PDF viewer and printer driver. Keep testing the calibration sheet before using more paper.
5. Print the tiled PDF with the same printer, paper and scale settings.

The preview is sized to your screen. It is not a ruler. The output PDF records physical dimensions, but the printer and its settings determine the dimensions on paper.

4. Join rows, then join the poster

Lay the sheets out in row and column order. R1 C1 is the upper-left sheet. Solid ticks mark cuts; dashed ALIGN ticks mark where an incoming sheet should land. Use a ruler to connect each pair of solid ticks.

1. Build each row from left to right. Leave the first sheet's outside borders intact. On each later sheet, cut off the left white border. Place that trimmed edge on top of the preceding sheet at its ALIGN ticks. Keep the preceding sheet's repeated right-hand artwork underneath.
2. Join completed rows from top to bottom. On the second and later rows, trim the top white border across the joined row. Place it on top of the preceding row, matching the ALIGN ticks at the far left and right. Keep the preceding row's bottom overlap underneath.
3. Check the joins before taping. Compare lines or image features across the seams, then tape on the back. Avoid stretching or bending the paper while aligning it.
4. Trim the outside last. After the whole poster is joined, cut the four outside edges through the layers. Small final fragments are easier to handle while their surrounding paper is still attached.

With zero overlap, the artwork edges meet instead of repeating. Keep the right and bottom white paper borders as support tabs underneath the incoming sheets. If guides are turned off, the PDF has no cut or alignment marks; the guide-based method above assumes they are on.

Troubleshooting

The image looks cropped in the preview

Select Full poster. A Print sheet view deliberately contains only one region. PDF to Letters uses the PDF's visible page boundary (its CropBox within its MediaBox); artwork already outside that boundary must be restored in the original PDF editor.

The printed poster is too small

Check for Fit, Shrink, multiple pages per sheet or a second poster-tiling setting in the print dialog. Return to the calibration page and measure the printed square. Do not compensate by guessing a larger finished size.

Marks near the paper edge are missing

Use a larger printer margin and regenerate the tiles. Check the new sheet count and reprint the complete set using the same settings; old and new tile grids may differ.

The last row or column looks mostly blank

A small strip may need an additional sheet to preserve the requested size. Full poster shows where it belongs. Auto orientation may use fewer sheets. Reducing the finished size also reduces coverage, but changes the intended dimensions.

The PDF will not open or export

The limits are 50 MB, 200 source pages and 200 output sheets per selected page. Password-protected files need an unlocked copy. Visible annotations, forms, optional layers and unsupported transparency need a flattened, static PDF. Export a separate copy from your PDF editor, then compare it with the original before printing.

The photograph looks blurry

Enlarging a PDF also enlarges any raster images it contains. PDF to Letters cannot create detail absent from the source. Use a higher-resolution original if available.

The download did not start

Wait until the tool says PDF ready, then use Download again. Check the browser's download controls. The generated link belongs to that page session; if you reload, reopen the PDF and generate it again.
