Frequently Asked Questions

What is an aspect ratio?

An aspect ratio is the proportional relationship between the width and height of an image, video, or screen (e.g., 16:9 means for every 16 units of width, there are 9 units of height).

How do I calculate a new dimension keeping the same ratio?

Once you know the ratio, you can multiply your new desired width by the height ratio divided by the width ratio to find the correct new height.
