The event images are displayed in several places with different sizes, which is fine. The worry is that the image may well caliber but sometimes not (see screenshot).
Is there an ideal ratio with respect to the image to be displayed in good conditions in all situations?
I feel that 1:1 goes well but I wanted your opinion (I have not found in your database).
Thank you for reaching out. The featured image size often depends on your theme width, layout, etc. With either CSS or a little custom code, featured images shouldn’t be too much of a worry. We have a Knowledgebase article geared towards Featured Images which I invite you to read.
Please let me know if you have any more questions on the matter and have a great afternoon. Cheers!
