Frequently Asked Questions
What is an aspect ratio?
An aspect ratio is the proportional relationship between the width and height of an image or screen. It is usually expressed as two numbers separated by a colon (e.g., 16:9), representing the width relative to the height.
How do I calculate the aspect ratio?
Enter the original width and height of your image or video into the calculator. The tool will divide the width by the height and simplify the fraction to give you the ratio (e.g., 1920x1080 simplifies to 16:9).
What is the difference between aspect ratio and resolution?
Resolution refers to the total number of pixels in an image (e.g., 1920x1080), which determines the detail and quality. Aspect ratio refers only to the shape of the image (e.g., 16:9), regardless of how many pixels it contains.
Why is 16:9 the most common aspect ratio?
16:9 is the international standard format for HDTV, widescreen televisions, and most online video platforms like YouTube because it offers a good balance between horizontal and vertical viewing fields.
Can I calculate new dimensions based on a ratio?
Yes. If you know your desired aspect ratio (e.g., 4:3) and you know either the new width or the new height, the calculator can determine the missing dimension to ensure the image does not stretch or distort.
What aspect ratio should I use for Instagram?
Instagram supports several aspect ratios. Square photos are typically 1:1, while vertical Stories and Reels use 9:16 (1080x1920). Landscape posts often work best at 1.91:1 or 16:9.
