The ratio of width to height in a flat surface or 2-dimensional abstract construction, such as an image, character, or pixel. 4: 3 (or 1.33: 1) is the standard ratio for NTSC video. 1.85: 1 and 2.35: 1 are the most common aspect ratios for motion pictures
The ratio of width to height in photographic prints - 2: 3 in 35 mm pictures to produce photographs most commonly measuring 3 5 x 5 inches or 4 x 6 inches; Advanced Photo System cameras deliver three aspect ratios as selected by the user See also Interspersed Aspect Ratio The Advanced Photo System's three user selectable print formats: "C" - 2: 3 aspect ratio used in 35 mm photography "H" - 9: 16 aspect ratio used by high-definition television (HDTV) "P" - 1: 3 aspect ratio produces prints of 3 5 x 10 5 inches or up to 4 5 x 11 5 inches; suitable for panoramic shots
The ratio of the width of a television picture or television screen to its height The ratio for conventional television systems is 4: 3 In advanced television systems (e g widescreen) the ratio is usually 14: 9 or 16: 9, which better approximate the aspect ratio used in cinema
The dimension of a mailpiece expressed as a ratio of length divided by height (for letters and cards, length is the dimension parallel to the address as read) For example, a postcard 5-1/2 inches long by 3-1/2 inches high has an aspect ratio of 1 57 An aspect ratio between 1 3 and 2 5, inclusive, is required for automation compatibility Also see nonmachinable surcharge
Lateral - the ratio of the length of a structure in the plane of the wafer to its width in that plane Vertical - the ratio of the height of a structure perpendicular to the wafer's surface to its depth in the wafer's plane
Specifies the height-to-width ratio of a plot This term is also applied to characters For example, characters with an aspect ratio of 2 0 are twice as tall as they are wide
(1) (n ) The ratio of the height of an object to its width (2) (n ) In computer graphics, the ratio of a pixel's height to its width Pixels that have equal height and width are called square pixels
The proportions of a TV or film picture, generally given as the ratio of the width to height The standard TV picture has an aspect ratio of 4x3, or 4: 3 High-definition video systems may have aspect ratios of 6x8 or greater
The relationship of width and height When an image is displayed on different screens, the aspect ratio must be kept the same to avoid either vertical or horizontal stretching
In computer displays and graphics, the ratio of the width of a picture or picture area to its height For example, an aspect ratio of 2: 1 indicates that the picture is twice as wide as it is high The aspect ratio is an important factor in maintaining correct proportions when a picture is incorporated into another document such as a Web page
The wingspan divided by the chord Aspect ratio is important where a wing's efficiency is concerned A short aspect ratio (short wings) is better for maneuvering, since it allows a high roll rate Short wings are also stronger than long wings Gliders use high-aspect ratio wings (long, skinny wings) because they are more efficient for soaring flight Example: 10 ft wingspan with a 1 ft chord has an aspect ratio of 10
The width-to-height ratio of a television picture Today's analog TV pictures have an aspect ratio of 4: 3 That is, the picture is slightly rectangular, being wider than it is tall The high-definition mode of digital TV presents the picture in an aspect ratio of 16: 9, almost twice as wide as it is tall This is similar to the pictures shown in movie theaters
The ratio of image width to image height Weather Facsimile (WEFAX) images have a 1: 1 aspect ratio (square); a conventional TV aspect ratio is 4: 3 (rectangle)
The ratio of the width (q v ) of the flag to its length (q v ) For example, a flag 36 inches along the hoist (width) by 60 inches from left to right (length) would have an aspect ratio of 1: 1 67 In some circles the words height and width are substituted for width and length, respectively Also, scientifically speaking, aspect may also use the width as the base reference, making the preceding example 1 67: 1
