Most guides to Netflix subtitles stop at “tap the screen and choose Audio & Subtitles”. That is thirty seconds of the story. The questions people actually have — why the settings never stick, why the audio keeps resetting, why a language vanishes between series one and two — all have documented answers, and almost nobody publishes them.
The quick version
To change subtitles or audio on something you’re watching:
- Phone, tablet or computer: tap or click the screen, then select Audio & Subtitles
- TV or streaming device: press the up or down arrow on the remote, then select Audio & Subtitles
- Apple TV: swipe up, or press the up arrow on the remote
You will see every language available for that title. Choose one and it applies from that moment.
One thing worth knowing immediately: a downloaded title only carries the two most relevant languages, not the full set. If you need a specific language offline, check it is there before you travel.
Why your subtitle settings never stick
This is the most common complaint about Netflix subtitles, and it is not a bug. Netflix has two separate subtitle appearance systems, and people assume there is one.
| Account settings (per profile) | Device player settings | |
|---|---|---|
| Where | Netflix website → Account → Profiles | On the TV, during playback |
| Options | Font, size, shadow, background colour | Size and style only — noticeably fewer |
| Applies to | That profile, across devices | Broadly that device |
So if you carefully styled your subtitles on the television and then found your phone unchanged, nothing is broken. You used the weaker of the two systems.
The fix: set subtitle appearance on the Netflix website, under your profile. That is the setting that travels properly.
Changing subtitle appearance properly
Web browser — the one to use:
- Go to your Account page
- Open Profiles and select the profile
- Choose Subtitle appearance
- Adjust font, size, shadow and background colour, then save
On a TV: pause playback, open the player controls, select the settings icon, and adjust size and style. Fewer options, as above.
On Android: My Netflix → your profile name → Manage Profiles → select the profile → Subtitle Appearance. Note that these changes apply to mobile playback only.
On iPhone, iPad or Apple TV: subtitle styling is handled by Apple’s own accessibility settings rather than by Netflix, so you change it in the device settings.
When appearance options don’t work at all
Netflix documents several genuine limitations: styling may be unavailable for certain languages on some televisions, older devices may ignore your chosen appearance entirely, and the feature is not offered in countries where Arabic or Hebrew is the primary language.
Audio keeps resetting to the wrong language
An oddly specific problem with an oddly specific official answer.
Netflix’s own guidance is to watch a title rated Teens or above for two to three minutes with your preferred audio selected. That is what registers the preference against your profile.
The reason is the second thing worth knowing here: subtitle and audio preferences are not saved when you watch most Kids titles from an adult profile. They are saved inside an actual Kids profile.
So the classic case — a parent putting a children’s programme on from the main profile, setting the audio, and finding it reset every time — is documented behaviour, not a fault. The real fix is to use a proper Kids profile, which also gets you the parental controls.
When your language simply isn’t there
Netflix gives four reasons a language may be missing:
- Your location — language availability varies by country
- Your profile’s language preferences — worth checking before assuming the title is at fault
- The title itself — down to content licensing and the agreements behind that show
- Your device — some hardware cannot display certain languages
Two specifics worth knowing, both from Netflix directly:
Devices made before 2014 may not display subtitles in Arabic, Chinese, Hebrew, Hindi, Japanese, Korean, Thai, Romanian or Vietnamese. If you are watching on an older television, that is the likely explanation.
Different seasons of the same show can have different languages available, because seasons may come from different subtitle and audio sources. A language present in series one genuinely can be absent in series two — you have not broken a setting.
Also: on series releasing weekly, language options can take time to appear after an episode goes live.
Display language vs audio language
These are separate settings and mixing them up causes needless confusion.
- Display language — the language of the Netflix interface itself: menus, buttons, descriptions
- Audio and subtitle languages — what you hear and read while watching
Changing one does not change the other. If the app is in the wrong language but your films are fine, it is the display language you want, set per profile.
Subtitles for the deaf and hard of hearing
Netflix labels titles offering SDH — subtitles for the deaf and hard of hearing — with a badge on the title’s details page. SDH goes beyond translating dialogue, describing sound effects, music and who is speaking.
Where a title offers both, standard subtitles and SDH appear as separate options in the Audio & Subtitles menu.
Frequently asked questions
Why don’t my subtitle settings carry across devices?
Because there are two systems. Settings made in the TV player are device-level and limited; settings made on the Netflix website under your profile are the ones that travel. Use the website.
Why does my audio language keep resetting?
Usually because the preference was set while watching a Kids title from an adult profile, where Netflix does not save it. Set it on a title rated Teens or above and watch for two to three minutes.
Why does a language disappear between seasons?
Seasons can use different subtitle and audio sources, so availability genuinely varies within a single series.
Why do my downloads have fewer languages?
Downloads carry only the two most relevant language options rather than the full set available when streaming.
Can I turn subtitles on permanently?
Netflix remembers your preference per profile once it is properly registered, but you may still see subtitles on parts of a title spoken in a language other than its original, regardless of your setting.
In short
Set appearance on the website rather than the television, use a Kids profile for children’s viewing if you want preferences to stick, and remember that missing languages are usually licensing or hardware rather than anything you have done.
