Fitbit Air Step Error Narrows to 5.2% After 69.7cm Stride-Length Tweak

Summary
A manually measured 69.7cm stride length lifted Fitbit Air’s 1,000-step test result to 948 steps from 930, improving accuracy to 94.8% from 93%.
Google Health estimates stride length from height and gender by default, and that setting appeared to drive undercounting; in a separate 5,000-step walk, the tracker missed roughly 650 steps—more than 10%.
The fix is to walk 20 normal steps, measure the distance, divide by 10, then enter that value in Google Health settings under Activity and Stride length.
The result suggests Fitbit Air’s $99 hardware can perform better with setup changes, though Google still does not prompt users to measure stride length during onboarding.
