The Block Poster Maker supports A4, Letter and bond paper. Match the paper size in the tool, printer tray and print dialog. A 1 × 1 grid makes a single-sheet A4 poster or Letter paper poster when you select the matching paper. Bond paper describes a type of paper, not a single size: short bond commonly means Letter, while long bond is 8.5 × 13 inches. Long bond is not US Legal (8.5 × 14 inches).

A LITTLE PRINT KNOW-HOW
What is tiled printing?
Tiled printing divides a large image into smaller sections that each fit on a sheet of paper. Tiled poster printing lets you assemble those sheets into one large picture with a home printer. To print a large image on multiple pages, choose a grid above. The Block Poster Maker exports the tiled layout as a printable PDF. Fit preserves the whole image; Fill covers the poster and may crop the edges. Optional overlapping strips make neighboring sheets easier to align.

SEAMLESS ASSEMBLY
Align the image details
The default overlap is 5 mm. Increase it to 10–15 mm for a wider alignment strip. Trim the outer margins at the crop marks, then match the repeated artwork on adjacent sheets.
IMAGE QUALITY
Choose an image for the job
Use a high-resolution original for photo walls, readable labels for classroom maps, and large type for event signs. Check the effective DPI before enlarging fine details.
GOOD TO KNOW
Frequently asked questions
A few helpful answers before your first print. Paper, picture quality, and everything in between.
01Is the Block Poster Maker free, and are my photos uploaded?
This block poster maker and its PDF download are free, with no signup or watermark. Image processing and PDF generation happen in your browser; the tool does not upload your image to a server.
02Print large image on multiple pages: where do I start?
In the Block Poster Maker, upload a JPG, PNG or WebP image, choose a page grid and paper size, then download the PDF. Print every page at Actual size / 100% with the same paper size, trim the margins and join the sheets using the overlap.
03What print margins should I use?
Start with the default 5 mm margins, or adjust them to your printer’s minimum printable area. Print the downloaded PDF at 100% / Actual size on the selected paper. Crop marks need at least 3 mm margins; page numbers need at least 4 mm. These annotations are omitted when the margins are too small.
04How is the block poster size calculated?
Pages = columns × rows. Printable tile width is paper width minus two margins. Poster width = columns × tile width − (columns − 1) × overlap; height uses the same formula with rows. With A4, 5 mm margins and 5 mm overlap, a 2 × 2 grid makes a 395 × 569 mm poster.
05How do I align the pages?
Trim off the outer paper margins using the crop marks. Arrange the pages by their row and column labels, then overlap adjacent image strips by the selected overlap amount (5 mm by default). Match the artwork before taping the back. Set overlap to 0 if you prefer to butt the trimmed edges together.
06Can I convert an image to multi-page PDF directly?
Yes. The Block Poster Maker lets you upload an image or use the example, adjust the layout, and select Download PDF. You get a multi-page PDF with the exact paper dimensions, optional crop marks and page numbers. No account or print dialog is required to download it. Open it in a PDF viewer to print at Actual size.
07Which resolution should I choose?
150 DPI suits many posters viewed at a distance; 300 DPI renders more output detail and produces larger files. The displayed effective DPI also considers your source image and enlargement. If it shows low resolution, use a larger original, reduce the number of sheets or decrease the image scale. Higher export DPI cannot recover missing image detail.
