I've had a fitbit for a couple years, and started with the default and changed my stride settings a few times before I used the method I used. Right now my fitbit distance is consistently accurate or very close for either walking and running distance compared to a measured track, treadmill, GPS, etc. The first method I used was counting steps while walking a short known distance, and it would result in too high of distance estimates for me (though I am sure it works fine for some people).
Where someone wears the fitbit can make a difference in how many steps it picks up. The distance can still be pretty good the fitbit is worn as you prefer and you use the fitbit counted steps in calculating your average stride length. Some people wear it on their waistband, some on a bra strap or cup, some clipped to a shirt pocket, some in a pants pocket and all of those will cause some variation in how it counts the "steps". That is really the main reason I suggest actually wearing the fitbit while you calculate stride length. It is probably fine to set your stride length before your fitbit arrives, but if you find it is giving distances too high or low compared to the actual distance, that is something to consider.
I was not saying that having a fitbit effects one's stride length. Just that if your goal is to set your "fitbit account" stride length to make the fitbit stats as accurate as possible, it may be more effective to do that while you are wearing the fitbit in the way you will typically wear it and using fitbit's step count over the distance.
Of course you can calculate stride length before getting your fitbit. It's got nothing to do with it.
Go measure out a known distance, eg 100m or the length of a football field or something.
Then walk it at normal pace 5-6 times. Count how many steps each time. This will give you an average number of steps per 100m. Divide for stride length.
Eg 130 steps per 100m would be (100/130) 0.77 metres stride length.

You might not need to. I had to, but if you don't calibrate your stride length it uses a default estimate based on your height. That actually is fine for some people. So I would personally wait until you have your fitbit and then walk a know distance and see how close it is. Which fitbit are you getting?
When I calibrated, I had tried a few different methods. I think it would be a little difficult to describe if you don't have your fitbit yet though. I used the steps my fitbit counted so it isn't something you could do without having your fitbit in your possession.
For those of you with a fitbit: how did you determine your stride length? I have a fitbit on it's way to me, and I know you have to determine your stride length. Any suggestions on how to determine this?
