		Aspect ratio refers to the relationship between the width and height of the viewing screen.
		Since the aspect ratio is of widescreen is closer to that found in movie theaters, there is plenty of room for the whole picture.
		However, because the aspect ratios do not match exactly, there may still be fl bars around the movie (making it either letterboxed or sideboxed or both), but they will be narrower and therefore won't affect the image area as greatly.

	Dunlop Tires \| Care & Maintenance \| Rim width and aspect ratio
		For example: For tires with aspect ratios from 80 to 50, the measuring rim, also called the design rim, is specified to be 70% of the section width.
		Aspect ratio is the relationship of a tire's height to width when mounted and inflated on a rim of the correct size.
		Aspect ratios are expressed in section height as a percentage of section width in two-digit numbers (80, 70, 60) and are often referred to as a tire's series.

		Aspect ratio is the SHAPE of the image, and is described as the ratio of the image's width and height dimension.
		An 10x8 inch print is the aspect ratio of 10:8 (10/8 = 1.25), but the fraction is reduced to be expressed as 5:4 (1.25), which is the same SHAPE as a 5x4 inch print.
		Aspect ratio is sometimes a fundamental consideration for sizing the image.

	Widescreen-o-Rama! All About Aspect Ratios
		The relationship between the width of a film image and its height is known as its aspect ratio, and from the early days of film (starting in the late-1890s) until the early-1950s, almost all films had a standard aspect ratio of 1.33:1 (technically, it was actually 1.37:1, but 1.33:1 is the recognized standard).
		In 1953, there were some 5 films released in a widescreen aspect ratio.
		There can be no doubt that widescreen films convey much more dynamic imagery, with the wider aspect ratio working to enhance the dramatic impact of the film upon the viewer.

	Appendix >> Online Help >> Aspect Ratio
		The aspect ratio of an image is its displayed width divided by its height (usually expressed as "x:y").
		Aspect ratios of 2.39:1 or 1.85:1 are frequently used in cinematography, while the aspect ratio of a sync-sound 35 mm film frame is around 1.37:1 (also known as "Academy" ratio).
		Since 4:3 is the aspect ratio of the usable frame within the Academy format once the soundtrack had been taken into account, films could be satisfactorily viewed on TV in the early days of the medium.

	DVDFILE.COM: What The Heck Is Anamorphic?
		Aspect ratio is a way of expressing the proportions of a screen; it's always stated as horizontal size versus vertical size.
		As the film's aspect ratio increases, more and more of the scan lines are thrown away; they are wasted, forced to reproduce the fl letterbox bars at the top and bottom of the video frame instead of reproducing picture information.
		Independent of the film's aspect ratio and the number of horizontal scan lines actively displaying picture content, anamorphic widescreen requires that all 480 horizontal scan lines are squeezed vertically from the conventional aspect ratio of 1.33:1 to an aspect ratio of 1.78:1.

	Aspect ratio (image) - Wikipedia, the free encyclopedia
		When cinema attendance dropped, Hollywood created widescreen aspect ratios to immerse the viewer in a more realistic experience and, possibly, to make the cinema experience more of a spectacle that could not be achieved at home on a regular TV set.
		A modified aspect ratio transfer is achieved by means of pan and scan or open matte, the latter meaning removing the cinematic matte from a 1.85:1 film to open up the full 1.33:1 frame.
		The ratio was 2.35:1 prior to SMPTE revision in 1970, and is still often mistakenly referred to as 2.35:1 although only anamorphic films photographed prior to 1970 are in the 2.35:1 aspect ratio.

		For instance, the aspect ratio of a traditional television screen is 4:3, or 1.33:1.
		Aspect ratios of 2.39:1 or 1.85:1 are normally used for movies, while the aspect ratio of a full 35 mm film frame with soundtrack (known as 'Academy standard') is around 1.37:1.
		Wider ratios such as 1.85:1 and 2.39:1 are accommodated within the 16:9 DVD frame by adding some additional masking within the image itself.

		Aspect ratios of 2.35:1 or 1.85:1 are frequently used in cinematography, while the aspect ratio of a standard 35mm film frame is around 1.37:1.
		The aspect ratio of a standard 35 millimeter frame is around 1.37:1, although cameramen may use only the part of the frame which will be visible on a television screen (which is 1.33:1 for standard television).
		The letterboxing is often careless, and the common 16:9 ratio does not precisely correspond to aspect ratios of the most common widescreen systems.

	Aerodynamics of Low Aspect-Ratio Wings
		At even lower aspect ratios the wing is subject to strong vortex flows and CL increases at a faster rate than that predicted with a linear theory.
		One important aspect is the behavior of the pitching moment with the lift coefficient, that is strongly dependent on the wing sweep and various technical devices (tip devices, fences, nacelles, etc.).
		In this correlation the aspect-ratio decreases as the sweep increases.

	What is Aspect Ratio?
		An aspect ratio is the ratio between the width and height of a film image.
		Many other aspect ratios are used in moviemaking, such as the European standard of 1.66:1, as well as some that have only been used for a few films, such as 2.76:1.
		Full-screen versions can be made with the original aspect ratio compromised by shooting only the part of the image that fits on a 4x3 set, a technique called "pan and scan." These videos contain a message explaining that the film has been modified to fit the screen.

		The widescreen format of HDTV has an aspect ratio of 16:9, meaning for every 16 units wide the set will be 9 units high, which results in a wider screen.
		The widescreen aspect ratio used by HDTV isn't exactly the same as the movies, but it's a happy medium between the most popular aspect ratios that director's use to shoot film.
		Film is produced in a variety of aspect ratios and 16:9 is only one of the four most popular used by Hollywood.

	Aspect Ratio and Image Cut-Off
		The aspect ratio (A/R) used to film the picture is not always the same as that employed to project or televise the film.
		This occurs when 16mm is blown-up to 35mm wide screen for projection with aspect ratios from 1.66:1 to 1.85:1, or when a 'scope film is optically scanned to produce a 16mm or 35mm flat film for television transmission.
		The problem of elongating the aspect ratio of flat films so that their screen proportion would approximate that of CinemaScope was solved by reducing the height of the projected image, using a shorter focal length projection lens and blowing up the picture onto a larger screen.
