Find an image aspect ratio, simplify it and calculate a matching height or width.
Any image width and height in pixels.
A simplified ratio such as 16:9 and a matching dimension.
The ratio is reduced using the greatest common divisor. The proportional field keeps the original shape instead of stretching.
No. It describes shape only. Quality changes when the image is resized, cropped or recompressed.
Square 1:1, landscape 16:9 and portrait 9:16 are common examples.
