Letterboxing, Open Matte, and Why Aspect Ratios Change How a Film Feels
Those black bars aren't wasted space — they're the frame the director chose. A guide to aspect ratios, what cropping destroys, and how to set your TV up to respect the image.
Every so often someone posts a complaint that a film on their TV “didn’t fill the screen.” The black bars at the top and bottom get blamed on the streaming service, the TV, the file — anyone but the actual cause, which is that the director chose a rectangle that isn’t the same shape as your television. And that choice is worth understanding, because the shape of the frame is one of the oldest tools in cinema.
A Brief Taxonomy of Rectangles
Ratio │ Name │ Feels like │ Signature use
─────────┼───────────────────┼─────────────────────────┼────────────────────────
1.33:1 │ Academy │ Intimate, boxed-in │ Classic Hollywood
1.66:1 │ European flat │ Literary, observational │ Art-house tradition
1.85:1 │ Flat / spherical │ Natural, invisible │ Default modern drama
2.39:1 │ Scope / anamorphic│ Epic, panoramic │ Blockbusters, westerns
Your TV is 1.78:1 (16:9). A 2.39:1 film letterboxed onto it loses about a quarter of the screen height to black — and gains a frame shape that makes landscapes breathe and faces feel mythologized. That trade is the whole point.
Why Shape Changes Meaning
Wide frames put people in space. Lawrence of Arabia in 2.20:1 makes the desert a character; squeezed into 4:3 for old television broadcasts it became a movie about people standing too close together. Narrow frames do the opposite — they isolate. Contemporary directors keep returning to 1.33:1 precisely because the claustrophobic square denies the viewer the horizon, forcing attention onto faces.
This is why “open matte” versions — where a film shot on taller film stock gets shown without its theatrical crop — aren’t a bonus feature. The extra vertical image was never composed to be seen. The boom mic famously appeared in some open-matte transfers because those regions of the frame were outside the intended composition.
The Sin of Pan-and-Scan
Older viewers remember pan-and-scan: technicians literally sliding a 4:3 window across a widescreen frame, cutting actors out of their own scenes and inventing camera moves the cinematographer never shot. It died with widescreen TVs, but its descendant lives on: some platforms still offer “fullscreen” crops of scope films on phones, quietly amputating a third of the frame.
Setting Up Your Screen to Respect the Image
- Turn off “zoom,” “fill,” and “fit” modes. If a stream arrives letterboxed, leave the bars. Stretching the image to fill is the same violence as cropping.
- Don’t fear the bars on OLED. Black pixels are off; the bars cost nothing.
- On a phone, rotate. Vertical crops of landscape films are the modern pan-and-scan. Landscape orientation on a phone shows more of a 2.39:1 frame than vertical ever can.

The Point
The bars aren’t missing picture — they’re the picture’s shape, agreed between director and format decades before your TV existed. Watch the frame as composed. The black is part of the film.
