Print a Large Image on Multiple Pages Free (A4 Tiles)

To print a large image on multiple pages, crop it to the shape of your final poster, cut it into equal tiles with the free image splitter (2 × 2 for four A4 sheets, 3 × 3 for nine), print each tile on its own sheet, then trim the margins and tape the sheets together from the back. A 2 × 2 grid of A4 sheets makes a poster about 42 × 59 cm, the size of A2, from an ordinary home printer.

This is how people make classroom charts, banners, maps and wall art without a print shop. Get the shape right before you split, so the tiles fill the pages instead of leaving white strips.

Plan the poster size first

Each A4 sheet is 21 × 29.7 cm. Stack sheets in a grid and the poster's size is just the sheet size times the grid:

Grid (columns × rows)	Poster size (portrait sheets)	Shape
2 × 2 (4 sheets)	42 × 59.4 cm	Portrait, same as A4
3 × 3 (9 sheets)	63 × 89.1 cm	Portrait, same as A4
2 × 3 (6 sheets)	42 × 89.1 cm	Tall and narrow
3 × 2 (6 sheets)	63 × 59.4 cm	Nearly square

Notice that 2 × 2 and 3 × 3 keep the A4 shape, about 1:1.41. For a wide landscape picture, turn the sheets sideways: a 2 × 2 grid of landscape A4 sheets is 59.4 × 42 cm.

The finished poster is a little smaller, because you trim each sheet's printer margin.

Check you have enough pixels

A poster is seen from further away than a photo print, so you don't need 300 DPI. About 150 DPI looks sharp at arm's length; 100 DPI is fine across a room.

Grid	Pixels for 150 DPI	Pixels for 100 DPI
2 × 2	about 2480 × 3508	about 1654 × 2339
3 × 3	about 3720 × 5262	about 2480 × 3508

A modern phone photo (around 4000 × 3000 pixels) cropped to the portrait A4 shape gives roughly 2100 × 3000 pixels: about 130 DPI on a 2 × 2 poster and about 85 DPI on a 3 × 3, which is fine from a few steps away. A small image from a website, say 800 pixels wide, will look soft and blocky when blown up across nine sheets. Use the largest version of the image you can find.

Step 1: Crop to the poster's shape

If the image's shape doesn't match the grid's shape, each tile will be the wrong shape for the paper, and the printer will leave white strips when it fits the tile to the page.

1. Open the free image cropper and choose your image.
2. For a 2 × 2 or 3 × 3 grid of portrait sheets, choose Free and type a Width (px) and Height (px) in the A4 shape, such as 2480 × 3508. For a tall 2-column, 3-row grid, use 2480 × 5262. The cropper refuses boxes above about 16.7 megapixels, so a 3 × 3 poster at 150 DPI (3720 × 5262) is too big; crop at 2480 × 3508 for 100 DPI instead.
3. Move the box over the part of the picture you want on the wall.
4. Save as PNG for an exact copy, and click Crop image.

If your image is larger than the numbers you typed, that's fine: make the box as big as fits while keeping the same proportions (for example, 3000 × 4243 is the same shape as 2480 × 3508).

Step 2: Split into tiles

1. Open the free image splitter and choose your cropped image.
2. Pick the grid: the 2 × 2 preset, the 3 × 3 (grid post) preset, or type Rows and Columns (up to 10 each). The 2 × 3 preset means 2 rows by 3 columns, so for a tall poster of 2 columns and 3 rows, type Rows 3 and Columns 2. Dashed lines on the preview show the cuts, and each tile is numbered.
3. Under the preview, check the tile size it reports, such as "4 pieces of about 1240 × 1754 px".
4. Choose PNG under Save as for no quality loss, or JPG at high quality if the files are huge.
5. Click Split into 4 pieces (or however many), then download the ZIP.

The tiles are numbered left to right, top to bottom. If the width doesn't divide exactly, pieces differ by at most one pixel, which you'll never see on paper.

Step 3: Print each tile

Open each tile and print it on its own A4 sheet:

• Set the paper to A4 and the orientation to match your sheets (portrait for the table above).
• Choose Fit to page (sometimes "Fit" or "Scale to fit") so the whole tile prints. Every tile scales by the same amount, so they still line up.
• Print all the sheets in one session with the same settings, so the colours match.
• Write the tile number lightly on the back of each sheet.

Step 4: Trim and tape

1. Lay the sheets face down in order. Remember that face down, left and right swap.
2. Trim the white margin off the edges that will meet another sheet. A paper trimmer or a metal ruler and craft knife gives straighter cuts than scissors.
3. Butt the edges together and tape along the backs of the seams.
4. For a sturdier poster, glue the finished sheets onto chart paper or thin card.

Why not just print it at a shop?

A print shop gives a seamless poster, which is worth it for an event banner or shop display. Tiling at home suits quick, cheap posters. For Instagram grids instead of paper, see splitting an image into a grid.
