Binder layout planner
Lay out a binder page before you commit sleeves to it — drop in your own images, span one picture across several pockets, and print the result at true card size.
Themed pages are easier to plan on a screen than in a binder. Pick a layout, drop images into the pockets, and drag to span a single picture across two, three, or all nine — the way connected card art works across a spread. Mark a pocket as a proxy for a card you do not own yet and it prints as a placeholder, so the page reads as finished while you hunt the real one.
Printing is at true card size, so what comes out of the printer drops straight into a 9-pocket page. Everything runs in your browser — no account, and nothing you add is uploaded anywhere. If you are still deciding what to build, the binder ideas hub has themed pages worth copying.
