When you touch the dough, it will be soft and your finger will leave an indentation when lightly pressed against the dough. If it is not ripe, the dough will tend to slowly spring back.
If you want light, fluffy bread, the dough should rise until it is puffy. The more gas incorporated in the dough, the lighter it will be. Of course, if too much gas is captured in the dough, it may collapse. The trick is to let it rise until you get just to the edge and then bake it. In most cases, that means that the dough will doubleor morein volume. With a free-standing loaf, since the pan cant support the loaf, you cannot let the bread rise as much.
How long should it take? A lean, moist dough in a warm kitchen will probably rise in 45 minutes or less. A firmer dough with less moisture will take longer to rise. Yeast is very sensitive to temperature; even a few degrees less in the kitchen can extend the rise time significantly. A change of 17 degrees (cooler) will...
