Hi!
Is there a way to get the aspect ratio of an image from the image url builder tool? I want to specify the width and height of all my images to avoid layout shifting, but I can't really find a way to figure out the height, given that I want the image to preserve its intrinsic aspect ratio.

Could this link help you? I think that in your case you need to handle assets, and not an image url

More over, having width and height of the image you could calculate the aspect ratio.

One solution would be to create the container for the image, within a div or a picture tag, and use the url as a background. So there you can specify height or the like.
A second solution might be to set the img tag in a div, and on the image tag you could use the css property object-fit: cover to not have any overflow or stretched image.

hm… well, thanks for putting me on the right track. Turns out, I can fetch the aspect ratio from an image with

image.asset->metadata.dimensions.aspectRatio

I see you found the answer! 🙂 We have a comprehensive article about image metadata in the docs if you have further needs in that regard!
