Drop a plumb bob (or any string with a small weight on one end so it hangs straight down) from the front of your forward knee. The weighted end should fall at the pedal spindle. This isn't a hard and fast rule, but it should be near it. If you are too far back, try a longer stem, instead. If too far forward, you may need a shorter one.
A professional fitting is the best way to go, but sometimes you just can't do that. Then it's time for some do-it-yourselfedness, with a bit of education.
