1.37:1 aspect ratio — classic cinema standard from silent era through 1950s. Rarely shot now, but powerful for period work or stylized flashbacks.
The 1.37:1 aspect ratio was the standard for decades—not because it was perfect, but because it was technically feasible and cinemas could show it. Originally stemming from the silent film era, it was established in the 1930s by the Academy of Motion Picture Arts and Sciences and shaped practically all black-and-white productions until the 1950s. On set, you immediately notice the difference: the image appears more square, more compact—it forces you into different compositional decisions than the wider 16:9 or 2.39:1 CinemaScope.
Today, filmmakers consciously opt for the Academy Ratio when they want to create temporal or emotional distance. A flashback in 1.37:1 immediately functions as a visual code for the audience—older, tighter, more intimate. When working digitally, it's purely a software crop or sensor cropping; with film, you used to actually need anamorphic lenses or masks in the camera. The advantage: less horizontal information means more vertical presence—faces appear more present, spatial depth is perceived differently. This makes the format tricky for wide shots, but excellent for portrait shots and emotional close-ups. Practically speaking: you need different focal lengths, different distances between camera and subject, to achieve the same visual effect as in modern formats.
Technically important: The Academy Ratio can be easily scaled up to modern formats—space is simply added or matted on the left and right. Conversely, it's complex to squeeze anamorphic or widescreen shots. That's why some DoPs consciously work with a documented Academy Ratio intention right from the shoot—framing is planned on the light stage so that the 1.37:1 crop sits cleanly and doesn't look like an emergency cut. The optics don't change, but your psychological proximity to the action immediately becomes closer.
