Common uses
The 27 × 40 inch one-sheet is a film-poster format. Measure an existing poster before choosing a frame; older and other film-poster formats can differ.
How it compares
Poster 24x36 is smaller in area. Foam board 30x40 is larger in area. These formats have their own proportions; halving a sheet does not necessarily produce the next size.
Cut a square for origami
The largest square from a flat rectangle this size is 685.8 × 685.8 mm (27 × 27 in). Fold one short edge against a long edge so their corners meet. Crease the diagonal, cut off the extra 330.2 mm strip, then open the triangle.
