Print Image on Multiple Pages
Turn any picture into a giant poster made of ordinary A4 or Letter pages. Choose how many pages wide or the exact poster size, and the tool splits the image into a multi-page PDF with overlap for gluing, cut marks, page labels and an assembly guide. Add a halftone dot effect for that classic wall-art look.

How to use the Print Image on Multiple Pages
- Add your picture: drop it on the box, paste it, or press Choose image.
- Choose paper and orientation: A4, A3, Letter or Legal in portrait or landscape.
- Set the poster size by number of pages wide or tall, or by exact width or height. The preview shows every page and the final poster size.
- Adjust margins and overlap, and pick Photo or Halftone dots style.
- Download the PDF and print it at 100% (actual size). Trim the margins along the cut marks and glue the pages together, using the assembly guide.
How the poster size is calculated
Each sheet contributes its printable area: the paper size minus a margin on both sides. Neighboring sheets share an overlap strip, so the poster grows by the printable width minus the overlap for every extra page:
- Printable width = paper width − 2 × margin
- Poster width = pages wide × (printable width − overlap) + overlap
- Pages needed = ⌈(poster width − overlap) ÷ (printable width − overlap)⌉, the same for the height
- Effective resolution (DPI) = image width in pixels ÷ poster width in inches
Example: A4 portrait is 21 cm wide. With 1 cm margins and 0.5 cm overlap, each page adds 18.5 cm, so 3 pages wide make a 56 cm poster.
Poster sizes with A4 and US Letter pages
Portrait sheets, 1 cm (0.4 in) margins and 0.5 cm (0.2 in) overlap:
| Pages wide | A4 poster width | Letter poster width | Pixels needed for 100 DPI (A4) |
|---|---|---|---|
| 2 | 37.5 cm (14.8 in) | 15.2 in (38.6 cm) | about 1,500 px |
| 3 | 56 cm (22.0 in) | 22.7 in (57.7 cm) | about 2,200 px |
| 4 | 74.5 cm (29.3 in) | 30.2 in (76.7 cm) | about 2,900 px |
| 5 | 93 cm (36.6 in) | 37.7 in (95.8 cm) | about 3,700 px |
| 6 | 111.5 cm (43.9 in) | 45.2 in (114.8 cm) | about 4,400 px |
Assembling your poster
- Print at 100%: in the print dialog choose Actual size, not Fit to page or Shrink oversized pages, otherwise the pages won't line up.
- Trim: cut along the cut marks. You only need to remove the left and top margins of each page (except the first column and row); the remaining margins are covered by the neighbors.
- Overlap and glue: lay each trimmed page over the overlap strip of the page to its left or above it, line up the picture, and glue with a glue stick or tape from the back.
- Work in order: assemble each row from left to right (A1, B1, C1…), then join the rows. The assembly guide on page 1 shows where every sheet goes.
Halftone dot posters look best viewed from a few meters away: the larger the dots, the further away the picture "comes together".
Frequently asked questions
How do I print one picture on several pages?
Add the picture, choose your paper and how many pages wide the poster should be, then press Download PDF. Every page of the PDF holds one part of the enlarged picture. Print the PDF at actual size (100%), trim the white margins and tape or glue the pages together in the order shown on the assembly guide.
Why do I need margins and overlap?
Most home printers cannot print to the very edge of the paper, so each page keeps a white margin you cut off. The overlap repeats a thin strip of the picture on neighboring pages, so small trimming errors don't leave gaps and you have a strip to glue onto.
What size will my poster be?
Each page adds its printable width (paper width minus both margins) minus the overlap. For example, 3 A4 pages wide in portrait with 1 cm margins and 0.5 cm overlap gives 3 × 18.5 + 0.5 = 56 cm. The tool shows the exact poster width and height before you download.
Will my picture be blurry when printed so large?
It depends on the picture's pixels. The tool shows the effective resolution in DPI (pixels per inch of poster). Above 150 DPI looks sharp up close, around 50 to 100 DPI looks fine from a few steps away, which is how large posters are viewed. The halftone dot style hides low resolution well.
What is the halftone dot effect?
It recreates the image with dots whose size follows the brightness of the picture: big dots in dark areas, small dots in light areas, like old newspaper photos and the well-known rasterbation posters. From a distance your eye blends the dots back into the picture, and it uses far less ink than a full photo.
Which printer settings should I use?
Open the PDF and print with scaling set to Actual size or 100%, not Fit to page, so the poster has the size shown and the pages line up. Turn off borderless printing and choose the same paper size you selected here.
Is my image uploaded?
No. The PDF is built in your browser with the Canvas API. The image never leaves your device.
