Fold-Out Page
A page that extends beyond the book’s standard size when unfolded, perfect for maps, wide illustrations, or detailed charts. It can be any page in the book, placed wherever it fits. It might be inserted as part of a signature during assembly, or tipped in later. The fold itself is typically a single fold, doubling the page width when opened, or an accordion fold for even greater expansion, depending on the design.
