The main difference between the Double Page Calendar and a Wall Calendar is the first one folds in the middle. The A2 Double Page Calendar hangs via a central spiral and top hole. Making it easier to change pages, transport and gift wrap. As a result of the fold, the A2 Calendar looks A3 when folded. The Personalised A2 Wall Calendar hangs from a top spiral and metal rail, requiring removal from the wall to turn pages. It also offers more customisation options like wooden covers and different paper types. This calendar is not folded when delivered and remains one size.
