If the paper has a watermark you should use the side where the mark is read correctly. If it does not have a watermark but has deckled edges, you should use the side where the edge is smooth not beveled.

If neither, then one trick I learned is to wet the paper and hang it by one corner, the paper will curve towards the "smooth" side.
