Tell the splitter above how wide you want the finished picture and which paper you have. It works out how many sheets that takes, lays the image across them with overlap for taping, adds cut marks, and exports one PDF you can send straight to a printer.

Drag any line to move a cut. Tab to a line and use the arrow keys to nudge it one pixel, or hold shift for ten.
Vertical cuts give side-by-side pieces. Horizontal cuts stack them.
The tool picks the rows and columns that keep the pieces closest to square.
A shared strip on each seam, so the sheets can be trimmed and taped.
Each piece is resized to the size this page targets before it is saved.
Your image never leaves your device. Splitting runs in your browser with the Canvas API.

Printing something bigger than a sheet of paper is a tiling problem, and the part people get wrong is not the cutting. It is the joining.
A plain grid split gives you pieces that butt up exactly, which sounds ideal until you try to tape them. Home printers cannot print to the edge, every sheet has a margin, and lining up two exact edges by hand across a metre of paper does not work. What you need is overlap: a few millimetres of the same picture repeated on both sheets, plus a cut line showing where to trim. Then you cut one sheet on the line, lay it over the next, and the picture continues.
So this tool works from physical measurements rather than pixels. Choose the paper, set the finished width in millimetres, and it calculates the sheet arrangement. A 4000 × 3000 photo printed 600 mm wide on A4 portrait takes 8 sheets (4 across × 2 down). The same photo at 840 mm takes 15 sheets (5 across × 3 down).
Paper sizes it knows: A4 at 210 × 297 mm, A3 at 297 × 420 mm, Letter at 8.5 × 11 inches, Legal at 8.5 × 14 inches and Tabloid at 11 × 17 inches, each in portrait or landscape.
Resolution is worth a thought before you commit. Around 300 dpi suits something people will stand close to, and 150 dpi is generally enough for a large poster seen from a few feet away. The tool shows the effective dpi for the size you have asked for.
Nothing is uploaded. The PDF is built in your browser.
A phone photo can cover a wall if you spread it across enough sheets. Set the finished width, pick your paper, and check the dpi the tool reports before printing. If it drops well below 150, either print smaller or start from a larger file, because no amount of tiling adds detail that was not there.
Plans need to print at a known scale rather than at a size that looks about right. Setting the target width in millimetres gives you that directly, and the overlap plus cut marks mean the taped sheets measure correctly across the joins rather than accumulating error.
A large map, timeline or poster made from ordinary A4 or Letter sheets costs nothing beyond toner and an hour of trimming. Cut marks matter here: several people trimming to the same printed line get a consistent result, where everyone judging the edge by eye does not.
Tiling a design at full size on cheap paper shows you how big it actually is and whether the type holds up, which a screen preview never does. Tape it to the wall, look at it from across the room, then send the real file to a shop.
Set the paper size and the finished width you want in the splitter above. It works out the sheet arrangement, lays the picture across them with overlap and cut marks, and exports a single PDF. Print that at 100 percent scale, trim on the marks and tape the sheets together.
It depends on the finished size and the paper. A 4000 × 3000 image printed 600 mm wide on A4 portrait takes 8 sheets (4 across × 2 down). On Letter portrait at the same width it takes 8 sheets (4 across × 2 down). The count is shown before you export anything.
Home printers cannot print to the edge, and butting two trimmed edges together by hand leaves visible gaps. A few millimetres of repeated image on both sheets lets you trim one, lay it over the next and slide it until the picture matches before taping.
Around 300 dpi for something viewed close up, and 150 dpi is generally enough for a poster seen from a few feet away. The tool shows the effective dpi for the finished size you have chosen, so you can see whether your source file supports it before printing.
A4 at 210 × 297 mm, A3 at 297 × 420 mm, Letter at 8.5 × 11 inches, Legal at 8.5 × 14 inches and Tabloid at 11 × 17 inches. Each can be used portrait or landscape, and switching orientation often changes the sheet count for a wide image.
No. The tiling and the PDF are built in your browser from your own file, with nothing uploaded and nothing to install. A print shop still makes sense for a single large sheet on heavy stock, but for a tiled poster on ordinary paper this does the whole job.
Almost always because the print dialog scaled the pages. Fit to page shrinks every sheet by a small amount, so the joins drift. Set scale to 100 percent or actual size. The second common cause is trimming both edges instead of only one and overlapping.
