There are multiple methods of calculating it, optimising the readings of the Activity Tracker.
Here are our three favorites:
1. At home:
- Put a tape measure on the ground in the biggest possible room.
- Walk along it and stop mid-step next to the tape measure.
- Now count the distance between heel and heel or tip and tip and note it down.
- Do this thrice.
- Add all values and divide by three.
- this is your middle length of step, which you can put in in your settings.
2. On the track:
- Take a preferably easy to calculate distance (like 100m for example).
- Now walk this in your average speed and count your steps.
- Now divide this distance (in cm) by the amount of steps.
- You now have your middle length of step in cm.
3. On the treadmill:
- Step on the treadmill and activate your Activity Tracker. Now remember the steps your tracker counted yet.
- Start the treadmill and set it to a tempo you're used to.
- The farther you walk, the more accurate the reading (500m should be enough).
- Take the steps you walked (difference between the value in the beginning and the one now) .
- Divide the distance you walked by the amount of steps and you have your middle length of step.
