A document folding method that uses two parallel folds to create six panels – three panels on each side of the paper. The left and right panels are roughly half the width of the center panels and fold inward to meet in the middle without overlapping.
Sometimes a gatefolded piece is folded inward one more time, along a central crease. This method is called a Closed Gatefold or Double Gatefold. The Closed Gatefold method creates eight panels – four panels on each side of the paper. All panels are roughly the same width.
