Aspect ratio is the proportional relationship between an image's width and height. For example 16:9 means for every 16 units of width there are 9 units of height — the standard widescreen format.
How do I resize an image without distortion?
Enter the original width and height, then enter either the new width or the new height. The calculator automatically calculates the other dimension to maintain the original ratio.
What is the aspect ratio of a 1920×1080 image?
1920×1080 has a 16:9 aspect ratio, which is the standard for HD video, most monitors and televisions.
What aspect ratio does Instagram use?
Instagram supports square (1:1), portrait (4:5) and landscape (1.91:1) for feed posts. Instagram Stories use 9:16. The calculator includes presets for all common Instagram formats.
