WALL CALENDAR SIZE GUIDE: A0, A1, A2 AND ONE METRE
Every HugeAssCalendar shows the same thing — the whole year, one writable box per day. The only question is how much wall you are willing to give it. Here are the exact measurements and what each size feels like to write on.
Sizes at a glance
| SIZE | MM | INCHES | WALL NEEDED |

| A0 | 841 x 1189 mm | 33.1 x 46.8 in | Tall format, needs about 1.3 m of height |
| A1 | 594 x 841 mm | 23.4 x 33.1 in | Fits above most desks |
| A2 | 420 x 594 mm | 16.5 x 23.4 in | Fits almost anywhere, including rentals and dorms |
Which one should you pick?
1 metre square
BEST FOR: The full experience: family hubs, studios, team walls
WRITING ROOM: Largest day boxes — several words per day, comfortably
A0
BEST FOR: Hallways and narrow walls where height is easier than width
WRITING ROOM: Big boxes, a short line of writing per day
A1
BEST FOR: Home offices and bedrooms
WRITING ROOM: Medium boxes — a few words or a symbol per day
A2
BEST FOR: Small rooms, or a second copy just for one project
WRITING ROOM: Compact boxes — best for ticks, dots and colour coding
Measure your wall in five steps
- Measure the free wall space with a tape measure, width and height.
- Subtract about 10 cm on each side so the poster is not squeezed between a light switch and a door frame.
- Compare what is left to the sizes in the table above and pick the largest one that still fits.
- Check your writing: if you note full sentences on days, go one size up from what fits; if you use ticks and colours, a smaller size is fine.
- Mark the top two corners in pencil, then pin, tape or frame it.
