Right background size

Hi

I was wondering if you have a landscape game play with width size - 1024, what would be the ideal background image size to use so it blends when moving between scenes.

Thanks

 

I know someone here can help with an answer even though the question feels odd
Trust me no shame in me asking

 

Still no one can help me with this question? Alright will have to figure this myself

 

The background images get scaled to the width automatically. Everything will be 1136px which is the default resolution of BB. If you do this width it will blend. If not, there is a offset value you can play with.
