How do I set a default video quality on YouTube?

Last reviewed: October 22, 2026 · Markdown version

In the YouTube app on a phone, yes: one screen in Settings sets the quality for every video. On a computer or a TV, YouTube's help only describes changing the video in front of you. The phone instructions sit under the heading “To change the video quality for all videos”, and the Android page spells it out: “You can change the default quality for all the videos that you watch” (YouTube Help: Change the quality of your video (Android), read 22 October 2026).

Set it once on Android or iPhone

Tap your profile picture, then Settings, then Video quality preferences. The screen asks twice, once for mobile networks and once for Wi-Fi, and offers the same four choices each time (YouTube Help: Change the quality of your video (iPhone), read 22 October 2026):

Auto: “Changes to give you the best experience for your conditions.”
Higher picture quality: “Uses more data so videos may take longer to start or may buffer more often.”
Data saver: “Lower picture quality, but videos may start faster.”
Advanced: “Manually select high-quality resolution formats, like 1080p.” If you pick it, you may be asked for a resolution, and both phone pages warn that “Choosing the Advanced option may not be available for all videos.”

Our suggestion: the split between the two networks is the useful part. Data saver for mobile networks and Higher picture quality for Wi-Fi gives you sharp video at home without spending mobile data on it when you are out.

On a computer, one video at a time

The computer version of the page has one set of steps, for the video you are watching: in the video player, select Settings, click Quality, then pick a quality (YouTube Help: Change the quality of your video (computer), read 22 October 2026). That page has no section for all videos, so it documents no default for the website. If you have seen a browser setting or extension that pins a resolution, it is not something YouTube's help describes.

The TV steps on the same page work the same way: Settings, Quality, your choice, for the current video. The page also notes that on a TV “Some high-quality formats (for example, 1080p, 4K) may not be available for all devices,” because some devices do not support the compression YouTube uses for them.

Why the picture still changes after you set it

YouTube adjusts on its own: it “changes the quality of your video stream based on your viewing conditions,” and the page lists the factors as your connection speed, the player or screen size, your browser, and the original upload. That last one sets a ceiling no setting can lift: “If the video was recorded in standard definition, it won’t be available in high definition” (YouTube Help: Change the quality of your video (computer), read 22 October 2026).

So a video that looks soft with Higher picture quality chosen may simply have been uploaded that way. Our tip, not YouTube's wording: open the Quality menu on that one video; the list there is the place to see what it offers.

Other playback settings worth a look

Quality is one of several settings people expect to follow them around and that live on each device instead. The switches that stop the next video starting, and the previews that play as you scroll, are covered on stopping YouTube videos from playing automatically. If the real goal is less time watching rather than less data, daily time limits for YouTube sets out what the app and your phone each offer.
