How do I make a custom background that fits in landscape and portrait?
We would recommend creating a background that is 2048px by 2048px. This way, whether a device is in portrait or landscape, it will have the width and height to fit the background.
Background images should be saved as high quality .JPEGs, no more than 5MB.
You can download a template .PSD that includes guides here.
Alternatively, we offer a custom design service if you don’t have the facility to create your own background, or you want something extra special, email firstname.lastname@example.org to find out more.
