A practical guide to planner layout, fold lines, panels, calendar grids and print-ready artwork, for a planner that has to work both on the wall and in the hand.
A wall planner is usually judged in the state it spends least time in. It is designed on a large screen, zoomed out, with the whole year laid out in one clean view, and it is approved that way too. The recipient meets it differently. First they get an A4 rectangle out of an envelope or a magazine, showing whatever part of the artwork the fold happened to leave facing up. Only later, if it earns the chance, does it open out to the full sheet, with every crease running straight through the calendar.
That gap between the two states is the real subject of how to design a folded wall planner. The flat proof is only half the brief. Everything below comes back to three checks: the sheet (design at full unfolded size), the fold (know exactly where the creases land) and the face (decide what the recipient sees first).
Start With the Unfolded Planner, Not the A4 Folded Size
Folded wall planner artwork is built at the finished, unfolded size: 594 × 841 mm for A1 or 420 × 594 mm for A2, with bleed added all round. It should not be built as an A4 document and scaled up. A4 is only the folded size the planner travels in, not the size the artwork is designed at.
It also sets the working order: full sheet and fold positions first, then the calendar, then branding and the front panel. If you are still choosing between the two formats, the A1 vs A2 guide in this series covers that decision. The folded wall planners themselves are produced in both sizes and folded down to A4.
