Step Length: The distance from the heel print of one foot to the heel print of the other foot. This is the distance traveled forward by a single leg. An average that you will see listed in many places is 2.2 feet (0.67 meters) for women, but it depends very much on height.
Stride Length: This can mean the same thing as step length, or it can mean the distance traveled by the heel of one foot to the next time that same foot strikes down - in other words, two steps, since in that time the other foot has also touched down once. If you set your pedometer for your step length and discover it seems to be halving your distance, read the instructions again - it may want the stride length, which is two steps. Also, the reverse - if you at first thought the pedometer needed the stride length but you seem to be getting double the distance, read again as they may have really wanted the step length.
