Questions & answers

Good to know

Common questions about size, privacy, and cost.

How do I make a print-and-play card sheet?

Upload your card fronts, add a shared back, choose the card size and duplex flip edge, then download a PDF that interleaves a front page and its matching back page for every sheet.

Why do my card backs not line up when I print double-sided?

Every printer feeds paper a little differently, so the back is shifted by a millimetre or two. This tool lets you set an X/Y back-side offset (and choose long- or short-edge flip) so the backs land exactly behind the fronts, the thing most makers struggle with.

Long edge or short edge?

Match your printer’s duplex setting. Long-edge flip mirrors the backs left-to-right; short-edge flip mirrors them top-to-bottom. If the first test sheet is mirrored the wrong way, switch this.

What card sizes are supported?

Poker (2.5 × 3.5 in), Bridge (2.25 × 3.5 in) and Mini (1.75 × 2.5 in), tiled to fit a Letter sheet.

Are my card images uploaded anywhere?

No. Everything runs in your browser, your artwork never leaves your device and nothing is sent to a server.

Does it cost anything?

No, it is completely free, no signup.
