Free big poster printer
A big poster from your home printer.
Want a poster bigger than your printer? This tool splits your picture across A4 or A3 sheets and makes one PDF: a map page, then every sheet with its grid label, cut lines and a glue overlap. Choose A2, A1, A0, one metre or any width. The check shows how many sheets you need and whether your picture is sharp enough, and suggests a size that saves paper.

Questions, answered.
Is the big poster printer free?
Yes. It is free to use, with no sign-up and no watermark.
How do I print it the right size?
Print the PDF at 100% or Actual size, not Fit to page. Each sheet has a 7 mm margin because most home printers cannot print to the edge.
How do I put the sheets together?
Use the map on the first page. Cut the white edge off the left and top of each sheet on the dashed line (not the first row and column), then slide it over the sheet before it up to the small orange marks and glue.
How big can my poster be?
As big as you like, but your picture needs enough pixels. The check shows the resolution: about 150 DPI or more looks good from a step away.
Can OA Design print it in one piece?
Yes. A poster printed on one large sheet looks cleaner and lasts longer. Send us your picture and size on WhatsApp.
