Check Aspect Ratio of Images – Easy, Fast and Reliable
Aspect ratios are written as a formula of width to height: 3:2. For example, a square image has an aspect ratio of 1:1 because the height and width are the same. The image could be 500px × 500px, or 1500px × 1500px, and the aspect ratio would still be 1:1. As another example, a portrait-style image might have an aspect ratio of 2:3. FlexClip is an excellent online video editor as well as video maker; it also can work as a video aspect ratio converter to help you change the aspect ratio to 16:9, 4:5, 1:1, 21:9, and 9:16 in a few clicks.

It is commonly expressed as two numbers separated by a colon, as in 16:9. For an x:y aspect ratio, the image is x units wide and y units high. Widely used aspect ratios include 1.85:1 and 2.39:1 in film photography, 4:3 and 16:9 in television, and 3:2 in still camera photography.

About Aspect Ratio. The aspect ratio of an image defines the proportion between its width and height. It is always expressed as two numbers separated by a colon (x:y). For example, images with the aspect ratio of 16:9, no matter how big or small, will always have the width of 16 and the height of 9 units of the same length.

How to Calculate an Aspect Ratio
An aspect ratio indicates the shape of a video screen or image. Screens display images as a grid of colored squares or rectangles in a grid, and the width and height of that grid is the resolution.
These squares or rectangles are called pixels. The aspect ratio is the ratio of the number of columns to the number of rows of pixels that make up a video display or image.
Aspect Ratio Converter Freeware
An aspect ratio is often expressed as reduced to a common format based on industry standards.
To find the video aspect ratio reduce the aspect ratio to either 16:9, 16:10, or 4:3. Some video aspect ratios cannot be evenly reduced into these ratios, in which case they should be reduced to the number of columns to 1 row of pixels.
Cinema projection screens often use a ratio of 2.35:1 or 2.4:1, for example. Learn more about these on our projector calculator.
How to Reduce an Aspect Ratio
To reduce a ratio, find the greatest common factor of both the number of columns and the number of rows. Then divide the number of rows and the number of columns by the greatest common factor.
Example: let’s find the aspect ratio for a 3840 × 2160 resolution display.
The greatest common factor of both 3840 and 2160 is 240
num columns = 3840 ÷ 240 = 16
num rows = 2160 ÷ 240 = 9
aspect ratio = 16:9
How to Scale an Aspect Ratio
Sometimes you need to scale an aspect ratio to a larger or smaller resolution. To scale an aspect ratio, multiply both sides of the resolution by the scale factor.
Example: let’s double the 4k 3840 and 2160 resolution to find the 8k resolution.
Multiply both parts of the resolution by 2
num columns = 3840 × 2 = 7680
num columns = 2160 × 2 = 4320
Thus, 4k scaled to 8k resolution is equal to 7680 x 4320.

How to Convert Video to a Different Aspect Ratio
Sometimes video in one aspect ratio needs to be displayed on a screen that is a different resolution, for example, when displaying standard definition 4:3 TV on a high definition 16:9 display.
There are a few different ways to display video that is not the same aspect ratio as the screen.
Display a Different Aspect Ratio by Cropping
The video can be zoomed so that there is no extra space, which will crop part of the video.
Aspect Ratio Converter
For example, a 4:3 video can be zoomed to scale the width to that of a 16:9 screen, cropping the top and bottom of the video.
Display a Different Aspect Ratio by Pillar-boxing
The video can be pillar-boxed, keeping the video’s height the same as the display when the video aspect ratio is thinner than the display aspect ratio.
For example, a 4:3 video can be zoomed, scaling the video’s height to the height of the display, resulting in bars on either side of the video.
Display a Different Aspect Ratio by Letterboxing
The video can be letterboxed, keeping the video’s width the same as the display when the video aspect ratio is wider than the display aspect ratio.
For example, a 16:9 video can be zoomed so that the video’s width is the same as the display’s width, resulting in bars on the top and bottom of the video.
