What is the Image size on sunset-hair

Hello,

I am using the https://www.jotform.com/theme-store/theme/sunset-hair

theme & I am wondering what size the background image is? 

I am going to create a custom image to fit the back of the form, however I do not know the size. 

I managed to download the background image of the Sunset Hair Form Theme and the size of the image is 2000x1212.

If you have other questions or concerns, please feel free to let us know.
