A printed calendar competes with the one already in everybody's pocket. It survives for one reason: writing on paper by hand, in a place the whole household or classroom can see, does something a phone does not.
Which tells you what matters in the design — room to write, and legibility from across a room.
1. Year, month and week start
In the calendar maker, set the Year and Month for a single sheet. Week starts is the one to get right before printing thirty copies: Sunday is standard in the US, Monday almost everywhere else.
Getting it wrong is not subtle — every date sits in the wrong column — but it is easy to miss on screen because the grid looks correct either way.
2. Portrait or landscape
This is a real decision, not a preference.
| Orientation | Gives you | Use for |
|---|---|---|
| Portrait | Taller day cells | Writing appointments, family planners |
| Landscape | Wider day cells, fits a wall better | Classroom display, term overview |
If people will write in it, portrait. If people will read it from four metres away, landscape.
3. Grid lines and day numbers
Grid lines controls how visible the cell borders are. Heavier lines suit a wall calendar; lighter lines suit one that will be written on, where the handwriting should be the strongest thing on the page.
Day numbers sets how prominent the dates are. Large numbers help a classroom display; smaller ones leave more room to write.
4. What the PDF contains
The PDF contains setting decides whether you export the single month on screen or a full set — twelve months plus a year overview.
The full set is the one to use for anything you are giving away or selling. Exporting twelve months one at a time and assembling them by hand is how page eleven ends up with last year's dates.
5. Paper size
Every export is US Letter, 8.5 by 11 inches — the size the US market prints and the size Amazon KDP expects. Worth knowing before a print run of any size: if your printer is loaded with a different stock, set it to scale to fit rather than assuming the page matches the tray, or you get a calendar with margins that are almost but not quite right.
Seasonal note
Calendar demand is sharply seasonal and earlier than people expect. Next year's calendars are looked for from October, and the search is largely over by mid January. Planning a year of seasonal material covers the wider pattern.
