Print a large image across ordinary sheets with configurable overlap, paper margins, and row/column assembly labels.
Step by step
01Start with the real dimensions
Choose a landscape, diagram, or illustration from your device. Set the full poster width and height in millimetres. Image selection initially preserves the source aspect ratio; the width and height remain independently editable afterward.
02Edit and inspect
Choose home-printer paper, page orientation, printable margins, and the overlap between neighbors. The preview shows each numbered sheet. Larger overlap gives more repeated detail for alignment but increases the number of sheets in the job.
03Export and verify
Download the multi-page PDF and print at Actual size. Lay out the sheets using their row and column labels. Trim one of each pair of overlapping edges, align matching image details, and tape or glue the sheets from the back.
Why this one
Overlap is repeated artwork
An overlap is not a blank gutter. Neighboring sheets repeat the same strip of image so that the edges can be aligned accurately after trimming. Reducing the overlap too far can make a mostly featureless sky or background difficult to align.
Printer margins
Home printers usually cannot print to every edge. The tiler masks a real printable margin around the artwork and places assembly labels outside it. Changing orientation changes the usable tile width and height as well as the sheet count.
Poster resolution
Image sharpness depends on source pixels divided by poster inches, not on how many sheets are used. The resolution check flags a source that may look soft. The tool refuses layouts exceeding 100 sheets rather than producing an unexpectedly huge PDF.
FAQ
The poster tile printer splits the image into ordinary paper sheets that can be trimmed and assembled into a large poster.
A 10 mm overlap is a useful starting point in the poster tile printer. More overlap helps alignment but uses more paper.
The poster tile printer enlarges the existing image and reports approximate print resolution. It does not generate new detail or call an AI service.
The poster tile printer PDF contains all numbered sheets. SVG and PNG downloads contain a single sheet; use PDF for a complete assembly job.
