After essaying many sizes, and layouts, finally, there is a chosen format for Tarde: an eight-page fanzine plus a poster in the back, resulting from folding an A4 paper sheet. This configuration has several advantages: (1) it is relatively cheap to produce; (2) it is portable and easy to store; (3) it can be easily expanded if the topic requires that; (4) it can be filled with a lot of content even despite its relatively small size.
Still, that will not be the only format for this project. Despite nothing being planned ahead, it is certainly possible to use other setups to fulfill particular content requirements such as surveys, maps, galleries, and containers… Even in a long-term scenario, and that is something to consider after the pilot test, the chosen format may change. But for now, that’s what we have; and it is just great.
