The overlap strip repeats on neighbouring pages โ€” it's where you glue or tape, and it hides small trimming errors.

How to put it together

  1. Print the PDF at Actual size / 100%.
  2. Lay the pages out using the labels โ€” letters are rows (A at the top), numbers are columns (1 on the left).
  3. On each page, trim the white margin off the right and bottom edges along the crop marks.
  4. Lay each trimmed edge over the neighbouring page so the picture lines up across the overlap, then tape or glue from the back.

About the Poster Maker

๐Ÿงฉ Big prints at home

Split one picture across as many pages as you like โ€” a 4-page-wide poster on A4 comes out about 75 cm wide, all from an ordinary home printer.

๐Ÿ“ Exact size or page count

Pick how many pages wide, or type the exact width in centimetres or inches and the tool works out the pages for you.

โœ‚๏ธ Crop marks and labels

Every page has crop marks in the margin and a grid label like B3, plus an optional guide page with a map of the whole poster.

๐Ÿ” Sharpness check

The tool shows how many pixels per inch your photo will have at the chosen size and warns you before it gets blurry.

๐Ÿ”’ Private

Your picture never leaves your device โ€” the PDF is assembled in your browser.

๐ŸŽจ Ideas

Wall art, birthday banners, classroom displays, maps, sewing and woodworking patterns, life-size cut-outs and party photo backdrops.

Frequently Asked Questions

How do I print a large picture on several A4 pages?

Choose your picture, set how many pages wide the poster should be and download the PDF. Print it at Actual size, trim the right and bottom margins of each page, and tape the pages together using the labels and overlap strips.

How big can I make the poster before it looks blurry?

Look at the "pixels per inch" figure. Around 150 or more looks sharp up close; 100 is fine for something seen from a metre or two away; below about 70 it will look soft. A 12-megapixel phone photo prints nicely about 60 cm wide.

What overlap should I use?

10 mm is a good default: enough to glue or tape and to hide small trimming errors. Use 0 if you want to butt the pages edge to edge.

Why trim the margins?

Home printers can't print right to the edge of the paper, so each page has a white border. Trimming the right and bottom borders lets each page lie over its neighbour so the picture runs on without a gap.

Is my photo uploaded anywhere?

No. The picture is read and the PDF is made entirely in your browser, so it never leaves your device.
