Ideal album art size?

[FartManly]

What would you recommend as the ideal size (dimensions) for album art?

I know GMMP resizes album art as necessary when displaying it, but the less it has to resize, the better the quality.

I assume it depends on the phone's screen resolution. My resolution is 1280x720 (Galaxy Note 2).

Thanks

i find anything above 512x512 looks good. But yes it is dependent on your displays resolution. The devices with higher resolutions tend to have more memory so they can handle the higher resolution images

For 1280x720 i would say the most efficient resolution would be 720x720. At that res the only scaling done would be for the background. Since its background opacity is lower, the scaling isnt as obvious

Perfect answer - exactly the info I was looking for. Thank you!
