GDevelop general

Hi everyone,
I want to start developing a Facebook game but I don’t know what is it the best screen size to use it for designing the game on Gdevelop

Thanks for your answer, I learned from it, but my problem is in the beginning of developing a new game on Gdevelop, we need to enter the height and width (see picture)
I think 760 px is a good width, but I don’t know the right height!
Thank you
