A good rule of thumb is to paint twice as big as your final output.
so for a theatrical render, 1920 x 1080, around 4K should do it. I also try to keep it the exact power of two for better sampling. So in this case,
3840 x 2160 but the bigger the better. I've done up to 7k... For bigger I have to split my PSD file into multiple doc. :(
And for characters or UV mapped models, 4~5K is pretty good. It might jam your render farm but if you have a render engine that allows tiles, (RenderMan*) you should be fine even with 8K.
But maybe I didn't get your question. Anyways, you guys let me know...
