F2

With dimensions of 420mm x 660mm, the F2 format has a total surface area of 0.2772 square meters. Belonging to the regional F series of Asian transitional paper sizes, F2 falls between F1 and the PA2 format. The landscape orientation and 4:3 aspect ratio align F2 with traditional East Asian paper dimensions while exceeding the area of PA2. F2 has no common alternative names but fits between the non-standard Royal and Antiquarian sizes. Typical uses include oversized graphic prints, custom folding displays, and regional packaging taking advantage of the sizeable area. As part of the F series adding useful grades between standardized formats, F2 itself lacks a distinct backstory and serves mainly to bridge the gap between F1 and PA2. Catering to a landscape orientation, the F2 dimensions lend utility where PA2’s narrower shape may fall short for regional use cases. So while the F series overall stems from localized Asian paper size traditions, F2 plays a simple role as horizontal step between two larger transitional sizes.
