When watching TV shows or movies on Netflix you can use about 1GB of data for each stream of standard definition video and up to 3 GB per hour for each stream of HD video.
If you are concerned with data caps or bandwidth limits, you can adjust your data usage settings by following the steps below:
- Sign in to Netflix.com.
- Select the profile you'd like to change your data usage settings for (this must be changed for each profile separately).
- Select Account.
- Under My Profile, select Playback Settings.
- Select your desired data usage setting
Please note that each estimate below is per stream, and that restricting data usage may affect video quality):
- Low (0.3 GB per hour) Medium (SD: 0.7 GB per hour)
- High (Best video quality, up to 3 GB per hour for HD and 7 GB per hour for Ultra HD)
- Auto (Adjusts automatically to deliver the highest possible quality, based on your current internet connection speed)
Select Save.
Note: It may take up to 8 hours for these changes to take effect.
