Film aspect ratios, from Academy to scope.
Movies are shot wider than TV. The two modern cinema standards are 1.85:1 flat and 2.39:1 scope; the calculator and crop below are preset to an exact 2.39:1 frame (2390 × 1000).

A 1920 × 1080 frame cropped to 2.39:1 keeps all 1920 pixels of width and only 803 of its 1080 rows; the removed 277 rows are what the black letterbox bars cover. Early sound films used the nearly square Academy ratio, 1.375:1, close to the 4:3 shape of classic TV.
Resizing preserves a source image's shape; cropping removes edges to fit a different one. Download the crop as PNG or JPEG above.

Television’s 16:9 (1.78:1) was picked as a compromise between the 4:3 tube shape and cinema scope, which is why films still letterbox on TV. IMAX on 70mm film reaches 1.43:1, the tallest common cinema frame.

What aspect ratio are most movies?
Most theatrical releases are 1.85:1 or 2.39:1. Big-budget epics lean to 2.39:1 scope; dramas and comedies often stay at 1.85:1 flat.
Why are movies wider than 16:9?
Cinema ratios were set decades before HDTV. 16:9 (1.78:1) was a TV compromise between the old 4:3 shape and scope, so films still arrive letterboxed.
