Ultrawide formats refers to photos, videos,[http://www.in70mm.com/news/2010/widescreen/ A History of Widescreen and Wide-Film Projection Processes] and displays[https://www.howtogeek.com/245935/all-about-ultrawide-monitors-the-latest-trend-in-gaming-and-productivity/ All About Ultrawide Monitors, the Latest Trend in Gaming and Productivity] with aspect ratios greater than 2. There were multiple moves in history towards wider formats, including one by Disney,p20, Sherlock, Daniel J. [https://wayback.archive-it.org/all/20080309094629/http://www.film-tech.com/warehouse/tips/WSMC20.pdf "Wide Screen Movies" Corrections], 1994–2004 with some of them being more successful than others.

Cameras usually capture ultra-wide photos and videos using an anamorphic format lens, which shrinks the extended horizontal field-of-view (FOV) while saving on film or disk.[http://www.red.com/learn/red-101/anamorphic-lenses Red Camera: Anamorphic lens intro]

Historic Ultrawide Cinema

Historically ultrawide movie formats have varied between ~2.35 (1678:715), ~2.39 (1024:429) and 2.4. To complicate matters further, films were also produced in following ratios: 2.55, 2.76 and 4.

Developed by Rowe E. Carney Jr. and Tom F. Smith, the Smith-Carney System used a 3 camera system, with 4.6{{overline|945}} (1737:370) ratio, to project movies in 180°.[http://www.widescreenmuseum.com/widescreen/smith-carney.htm Smith-Carney System] Disney even created a 6.85 ratio, using 5 projectors to display 200°. The only movie filmed in Disney's 6.85 ratio is Impressions de France.

Wide aspect ratios

Suggested by Kerns H. Powers of SMPTE in USA, the 16:9 aspect ratio was developed to unify all other aspect ratios. Subsequently it became the universal standard for widescreen and high-definition television.

Around 2007, cameras and non-television screens began to switch from 15:9 (5:3) and 16:10 (8:5) to 16:9 resolutions.

Extra-wide aspect ratios{{anchor|Univisium}}

Univisium is an aspect ratio of 2:1, created by Vittorio Storaro of the American Society of Cinematographers (ASC) originally intended to unify all other aspect ratios used in movies.

It is popular on smartphones and cheap VR{{clarify|date=May 2020}} displays. VR displays halve the screen into two, one for each eye. So a 2:1 VR screen would be halved into two 1:1 screens. Smartphones began moving to this aspect ratio since late 2010s with the release of Samsung Galaxy S8, advertised as 18:9.

Ultra-wide aspect ratios{{anchor|Ultrawide Cinema}}

21:9 is a consumer electronics (CE) marketing term to describe the ultra-widescreen aspect ratio of 64:27 (21{{frac|1|3}}:9) = 1024:432 for multiples of 1080 lines. It is used for multiple anamorphic formats and DCI 1024:429 (21.{{overline|482517}}:9), but also for ultrawide computer monitors, including 43:18 (21{{frac|1|2}}:9) for resolutions based on 720 lines and 12:5 (21{{frac|3|5}}:9) for ultrawide variants of resolutions based either on 960 pixels width or 900 lines height.

The 64:27 aspect ratio is the logical extension of the existing video aspect ratios 4:3 and 16:9. It is the third power of 4:3, whereas 16:9 of widescreen HDTV is 4:3 squared. This allows electronic scalers and optical anamorphic lenses to use an easily implementable 4:3 (1.3{{overline|3}}) scaling factor.

$\tfrac{4}{3} \cdot \tfrac{4}{3} \cdot \tfrac{4}{3} = \tfrac{64}{27}$

21:9 movies usually refers to 1024:429 ≈ 2.387, the aspect ratio of digital ultrawide cinema formats, which is often rounded up to 2.39:1 or 2.4:1

Ultrawide resolution can also be described by its height, such as "UW 1080" and "1080p ultrawide" both stands for the same 2560×1080 resolution.

32:9 aspect ratio is derived from 16:9 being twice as large. Some manufacturers therefore refer to the resulting total display resolution with a D prefix for dual or double.

Super wide resolutions refers to that with aspect ratio greater than 3.

Ultra-WideScreen 3.6 video never spread, as cinemas in an even wider ScreenX 270° format were released.[https://filmmakermagazine.com/76652-introducing-screen-x-cinema-in-270-degrees/ Introducing Screen X, Cinema in 270 Degrees]

4:1 (36:9)

Abel Gance experimented with ultrawide formats including making a film in 4:1 (36:9). He made a rare use of Polyvision, three 35 mm 1.{{overline|3}} images projected side by side in the 1927 film Napoléon.

AT NAB 2019, Sony introduced a 19.2-metre-wide by 5.4-metre-tall commercial 16K display.{{cite web

Multi-Screen Theaters

Developed by CJ CGV in 2012, ScreenX uses three (or more) projectors to display 270° content, with an unknown aspect ratio above 4. Walls on both sides of a ScreenX theatre are used as projector screens.

Developed by Barco N.V. in 2015, Barco Escape used three projectors of 2.39 ratio to display 270° content, with an aspect ratio of 7.17. The two side screens were angled at 45 degree in order to cover peripheral vision. Barco Escape shut down in February 2018.
