Aspect Ratio is the ratio of an image’s width to its height.
Usually 1:1, 2:3 etc. is written as. Before you start shooting a movie, it is necessary to decide on the aspect ratio. Stage setting, decor and framing are arranged according to this decision. Because the shape of the image is dictated by the aspect ratio.
The ratio of the horizontal and vertical dimensions of the graphic to each other is very important in graphic operations on the computer. Maintaining this ratio is an important detail so that the graphic does not deteriorate and can be opened properly by devices later on.

Definition of Aspect Ratio
The aspect ratio is a number that covers how wide your video is. It is the proportional relationship between the width and height of a video. Here are some examples: 1:1, 16:9 and 4:3.
1:1 = square
16:9 = widescreen
4:3 = standard
The aspect ratio is what your camera records, and most DSLRs record in a 16:9 aspect ratio.
What Are Common Aspect Ratios ?
The most common aspect ratios are 16:9 or 9:16, 4:3, 1:1 and 2.4:1.
16:9 is the standard widescreen aspect ratio we see everywhere on the web.
9:16 is the entire vertical video we watch on our phones. A perfect 90 degree rotation of 16:9 video.
Many TVs and movies were produced in these proportions in the 4:3, 80s and 90s. Camcorders from this time have a 4:3 ratio and are slightly wider than one frame.
1:1 is a full frame and is the aspect ratio of an Instagram or Facebook video.
2.4:1 is the ultra-widescreen or anamorphic aspect ratio. It is often used in movies to create a super cinematic feel.
Photography Aspect Ratio
In photography, aspect ratio represents the relationship between the width and height of an image. It can be expressed as a number followed by a colon followed by another number such as 3:2 or a decimal number such as 1.50 (long side divided by short side). Some even prefer to express the aspect ratio as a decimal number followed by a colon and the number 1 such as 1.50:1.
You can easily visualize any aspect ratio by assigning units to an image’s width and height. For example, a 4:3 aspect ratio consists of 4 equally sized units for its width and 3 equally sized units for its height. Similarly, an image with a 3:2 aspect ratio is represented by 3 equal size units for its width and 2 units for its height.
Current Video Standards
What does 4:3, 14:9 and 16:9 modes mean in camcorders, devices such as TVs and monitors. What do these modes, which are among the features of when you are going to buy a device, mean and which one should we choose when buying? These ratios are the frame rate, the first value is the width, the next value is the height. How will you decide which of these ratios to choose while recording video? Here is information about aspect ratios.
4:3 Mode
The 4:3 mode is the classic television screen and most of the Silent Period movies were shot in this mode. This means that every four units of a picture width will be three units high while in this mode. Thus, if you take your photos or videos recorded in this mode in 4:3 mode, the photos and videos will be fully reflected on the TV screen.
14:9 Mode
Allows a 16:9 TV to display 14:9 format broadcasts to use the entire screen by enlarging the picture until it fills the screen vertically.
16:9 Mode
The 16:9 (1.78:1) format is closest to the golden ratio. You can watch a video recorded in 16:9 mode or an incoming signal on a device operating in 4:3 mode. 16:9 mode is Full HD 1920×1080 resolution ratio.
