From Facebooks info:
<i>“<b>Your Page’s profile picture:</b>
Displays at 170x170 pixels on your Page on computers, 128x128 pixels on smartphones and 36x36 pixels on most feature phones.”</i>
On-click, it displays up to 850px by 850px, but the highest resolution Facebook will store is 2048px by 2048px. I would recommend the highest possible in png, and let facebook optimize it for different purposes.
