Distance is not being accurate

[04Dbacks]

Distance on Blaze is always about 1 mile less than actual distance.

Hello @04Dbacks without any details it would be hard to respond. 

Is this durring an exercise such as walk/run/bike or maybe it is while on a treadmill? 

If you are referring to a tracked exercise which mode was used to track the exercise.

Distance on treadmill and jogging outside is about 1 mile less than actual distance (I’ve GPS’d it)
On treadmill, I must use rails because I have vertigo. Outside, I use my arms when I jog, but distance is under by about 1 mile, as well.
Steps inaccurate on treadmill and jogging outside.

I would increase the stride. 

What is needed is 

True miles

Fitbit miles 

Current stride setting

With a little math we can get the stride set accurately

It's great to see you here @04Dbacks and @Rich_Laue thanks for stopping by.

Fitbit trackers calculate distance by multiplying your walking steps and walking stride length. Similarly, your running steps are multiplied by your running stride length. This will not necessarily match a pre-measured distance, nor will it show exactly what a GPS device will show.

As recommended, please measure your stride length information since, if you don't input your stride length, the site and tracker will use a default setting based off of your height and gender. As long as you've entered that information, the stride length it uses should be fairly accurate.

I hope this helps, let me know the outcome.

I don’t understand: what good is the distance tracker, then?
Or the calorie counter?

To be honest your tracker, without GPS is unable to measure distamce, but must calcilated. 

As for calories the tracker looks at the heart rate, and uses this to calculate calories. 

Yes there is more accurate ways but they require the monitoring of the oxygen consumed.
