Printing guides & tutorials
Thirty-three guides on printing large images, posters, and banners at home on the printer you already own. Grouped by what you're starting from, so you can go straight to the one that matches your job.
Start here
The core method, whichever size you're printing.
How to print a large image on a regular printer

FAQ & complete guide
Every question we get asked, answered in one place: formats, privacy, seams, scaling, paper.
By paper size
What your printer takes decides the grid.
Split an image onto 8.5 × 11 pages
US Letter math: how many sheets each poster size needs and why Letter and A4 don't mix.
Split an image into 4 A4 pages
The 2 × 2 grid that lands on a real poster size, and the 6 mm of margin that decides it.
Split an image into 9 pages (3 × 3 grid)
Nine sheets means twelve seams. How to plan them so the middle page doesn't drift.
Print an A3 poster on A4 paper
The smallest useful split: two sheets, one seam, and where to put it.
Print an A2 poster on A3 paper
Two A3 sheets or four A4: the trade-off between seams and paper.
Print an A1 poster on A4 paper
Eight sheets, four across. Overlap stops being optional at this size.
By poster size
The two standard US frame sizes, plus what any of it costs.
How to print an 18 × 24 poster at home
Six or nine Letter sheets depending on orientation, and the resolution that holds up at 18 in.

Twelve sheets in three exact columns, how to assemble seventeen seams, and fitting the result in a frame.
Print a poster at home without a large-format printer
Why tiling beats a wide-format printer for anything you'll print fewer than a dozen times.
How to make a DIY poster at home
Design to print to wall: choosing an image, sizing it, and mounting it so it stays flat.
How much does it cost to print a poster at home?
Per-sheet ink and paper costs against print-shop quotes, size by size.
By what you're printing
Each source has its own gotcha. These cover them.

Export settings that keep Canva's resolution, then tile it without a print shop.
Print a Google Slides poster
Slides exports at screen resolution by default. How to get a printable file out of it.

Vector PDFs scale cleanly; scanned ones don't. How to tell which you have and split either.
Print AI-generated images at poster size
Midjourney, DALL·E, and Stable Diffusion output is small. Upscale first, then split.
Print Instagram carousel images
How big a 1080 px post can honestly print, and the gallery-style grid of squares that actually works.
Print a long screenshot or full webpage
Tall, narrow captures split into a readable column of pages instead of one unreadable sheet.
Print photos larger than printer size
Where a phone photo runs out of pixels, and how big it can honestly go.
Print a banner on a regular printer
One row of pages, overlapped and taped into a strip. Text and colour tips for readable banners.
Print engineering drawings & blueprints at home
Keeping a CAD drawing to scale across sheets so measurements off the print still mean something.

Maps punish blurry seams. Overlap, cut-line guides, and paper choice for wall-sized maps.

A couple of dollars at home instead of $30–80 at a shop: design in Canva at full size, hit green DPI, hide the seams.
