How to print bingo cards and puzzles cleanly
Printing is the whole point of this site, so the pages are built with print rules rather than hopeful CSS. Here is how to get the result you see on screen onto paper.
- 01
Choose your paper size first
Pick A4 or US Letter in the generator before printing. The page layout is built in millimetres for the size you choose, so switching afterwards is what causes cut-off grids.
- 02
Check the preview at 100%
The on-screen preview is scaled to fit your window. Before printing, confirm the sheet still looks right — the paper size label next to the Print button tells you which size is active.
- 03
Open print preview and set margins to default
Use the browser print dialog (Ctrl+P or Cmd+P). Keep margins on "Default" — the page already sets a 12 mm margin through print rules, and adding browser margins on top squeezes the grid.
- 04
Turn off headers and footers if you want a clean sheet
Browsers add a date and URL by default. Disable "Headers and footers" for a tidy handout; leave it on if you want the source URL printed for your own records.
- 05
Use card stock if the cards will be handled
Standard 80 gsm paper is fine for one round. For classrooms and parties, 160 gsm card survives being written on, passed around and carried home.
Why cards sometimes get cut across two pages
A card is split when the printable area is smaller than the sheet the layout was built for. That happens when the paper size does not match (A4 layout printed on Letter, or the reverse) or when the browser adds its own margins on top of the page margins. Both are fixed by matching the paper size and leaving the browser margin setting on Default.
What disappears when you print
Navigation, footer, buttons and the preview controls are all hidden in print. The output is black line art on white, which is cheap to print and easy to colour in. Nothing that appears on paper comes from outside your browser.
Saving as PDF
Choose "Save as PDF" in the print dialog instead of a physical printer. The result is identical to the printed page, including the page size, which makes it easy to email a set to a colleague or send it to a print shop.
