The original screenprinted blue and silver calendar measures approximately 30cm x 80cm. There is now also a Southern-hemisphere version available!
I've also made an A5 (approx. 21cm x 15cm) month-by-month planner, with 12 tear-off sheets, which you can write on.
Note that the images below are not to the same scale! - the blue poster is in fact much larger than the planner.
