What is the suggested size for a header image?

What is the suggested size (or best size) for a Jorform form header image? I would likely use 1200 x 630 pixels. Does Jotform staff have a suggestion here?

Hi,

600x315 to 1200x628 pixel size is recommended for social media's link share images, so 1200x630 pixels is a good choice.

Don't hesitate to reach out if you have further questions.
