What is the recommended image size for form background?

What are the dimensions for form background image?

We don't have a specific recommendation for image size. Since we allow large image uploads. Also, the image size may be quite different based on device you're using to view your form. However, it is generally recommended to use optimized images due to performance reasons. If you can give us the URL of the image and form where you want it, maybe we can give you the best possible size for that form and that image.

We'll wait for your response.

Thank you!
