Using Your Aria 2 
Your Fitbit Aria 2 scale measures your weight, body fat percentage, and BMI. When 
connected your Fitbit account, measurements from your scale will automatically and 
privately sync to your dashboard.  
Completing a weigh-in 
Follow these steps to complete a weigh-in on your Aria 2: 
1.  Place the scale on a flat, hard surface.  
2.  Remove your socks and shoes and then step onto the scale while barefoot.  
 
 
Aria 2 will display your weight and body fat measurement. 
 
3.  Step off the scale. Aria 2 will automatically send your stats to your dashboard.  
 
If you see an error message on your scale, see help.fitbit.com. 
Viewing your data 
After you’ve weighed yourself and your Aria 2 has synced, you can view your data in 
your dashboard. The dashboard is where you’ll track progress, view your stats 
including lean mass on a graph, and manually enter or delete a weight.

Inviting other users to use the scale 
Up to eight users can sync their Fitbit accounts with a single Aria 2 scale. If someone 
who does not have an account linked with the scale steps on the scale, only their 
weight will display (body fat percentage and BMI won’t appear). Registered users will 
see this weigh-in attributed to “Guest”.
