Netflix doesn't publish one font for its subtitles. The style guide it gives to subtitle makers says only: "Font style: Arial as a generic placeholder for proportionalSansSerif", in white. The subtitle file asks for a plain proportional sans-serif, and the device you watch on decides which font draws it. Netflix also has its own typeface, Netflix Sans, and Dalton Maag, the foundry that built it with Netflix, says it was designed for uses "from striking billboards to micro scale subtitles". No Netflix page says which devices show subtitles in Netflix Sans, so the honest answer is a clean sans-serif chosen by your device, unless you pick another font in your subtitle settings.
YouTube is easier to pin down. Its web player's default caption font is a list that starts with a font called YouTube Noto, then Roboto, then Arial, in white on a near-black box. The details for both, the closest free fonts, and how the streaming look compares with captions burned into social video, are below.
What font Netflix uses for subtitles
Three Netflix sources, read on 19 October 2026, each give part of the answer.
The style guide. Netflix's English (USA) Timed Text Style Guide has the same font block for its SDH and its standard subtitles: Arial as a placeholder for "proportionalSansSerif", a size set by the video's resolution and the need to fit 42 characters across the screen, and white text. Its general requirements add that font size in the delivered file is always 100%. In other words, the file names a kind of font, not a specific one.
The partner article on forced subtitles. Netflix tells the studios that deliver subtitles that, because forced subtitles travel as separate timed-text files to many kinds of device, there is no way to guarantee how they look, and the font "may vary in look depending on the viewing device". A screenshot in the same article shows the web font menu with seven choices: Typewriter, Print, Console, Block, Casual, Cursive and Small Caps. The screenshot looks older than the text around it, so treat those names as a guide; the current menu may differ.
The help center. Viewers can change "the font, size, shadow, and background color" of subtitles and closed captions, according to Netflix's subtitle appearance help page. Netflix's announcement of dialogue-only subtitles on 24 April 2025 repeated that you can customize subtitles by changing the size and font.
Netflix Sans. According to a TheWrap report of 21 March 2018, Netflix's in-house design team built it with Dalton Maag, and Netflix unveiled it that week. Dalton Maag's portfolio page lists the project as a custom font family for Netflix, worked on from 2017 to 2023, with subtitles named among the uses it was designed for. It is Netflix's own font: Dalton Maag's page marks it "Exclusive to Netflix", and neither it nor Netflix offers it for download or licence.
Why streaming subtitles have no fixed font
Netflix isn't unusual here. Streaming subtitle files name a generic font family, and each player maps that name to a real font it has. The BBC Subtitle Guidelines (version 1.2.5, March 2026) show how much that varies: the HbbTV standard maps "proportionalSansSerif" to Tiresias, while the IMSC standard used online maps it to any font with substantially the same dimensions as Arial. For online players, the BBC advises using the device's own system font, giving Helvetica on iOS and Roboto on Android as examples, because unfamiliar fonts can make text less clear.
That is why Netflix writes Arial as a "placeholder". It pins down roughly how wide a line of text will be, so 42 characters fit across the screen, without pinning down the exact letter shapes you see.
How to change the subtitle font on Netflix
- Web browser: Account, then Profiles, choose a profile, then Subtitle appearance. Pick the font, size, shadow and background, then Save. On a TV, reload the Netflix app (Settings, Get Help, Reload) for the change to show.
- TV or streaming device: pause, open the player controls, and use Settings to change Size and Style. Netflix notes that TVs don't offer every option the browser has.
- Android phone or tablet: My Netflix, tap the profile name, Manage Profiles, choose the profile, then Subtitle Appearance.
- iPhone, iPad and Apple TV: Netflix sends you to Apple's own subtitle settings.
What font YouTube's captions use
YouTube's help page lets viewers change caption font, color, opacity and size, the background and window colors, and the character edge style, from Settings, then Subtitles/CC, then Options. The font names behind those choices are in the YouTube web player's code, which we read on 19 October 2026:
- Default, and "Proportional Sans-Serif": YouTube Noto, then Roboto, Arial, Helvetica, Verdana and PT Sans Caption. Your browser uses the first one it has.
- Proportional Serif: Times New Roman and similar serif fonts.
- Monospaced Serif: Courier New and similar typewriter fonts.
- Monospaced Sans-Serif: Lucida Console, Monaco, Consolas and similar.
- Casual: Comic Sans MS.
- Cursive: Monotype Corsiva and similar script fonts.
- Small Capitals: a small-caps setting.
The default style in the same code is white text on a near-black background at 75% opacity, and the text colors on offer are white, yellow, green, cyan, blue, magenta, red and black. So the YouTube caption font most people see is YouTube Noto or Roboto, white on a dark box, unless they have changed it.
The two platforms at a glance
As read on 19 October 2026 from Netflix's partner and help pages and YouTube's help page and web player:
| Platform | Font named in the spec or code | Default color | Viewer can change the font | Closest free font |
|---|---|---|---|---|
| Netflix | Arial as a placeholder for a proportional sans-serif | White | Yes, in Subtitle appearance | Arimo |
| Netflix brand type | Netflix Sans, a custom font by Dalton Maag | Not applicable | Not applicable | None; Inter is a clean stand-in |
| YouTube | YouTube Noto, then Roboto, then Arial | White on a 75% black box | Yes, in Subtitles/CC options | Roboto or Noto Sans |
The free fonts in the last column are all on Google Fonts under the SIL Open Font License, which allows commercial use. Arimo is designed to be metrically compatible with Arial, so text set in it takes the same width as Arial. Roboto is in YouTube's own font list. Inter is not a copy of Netflix Sans; it is our suggestion for a similar clean, modern sans-serif. For more choices, with weights and sizes for phone video, see the best fonts for video captions.
Getting a similar look on social video
The streaming look is plain on purpose: white sentence-case sans-serif, one or two lines, bottom center, a shadow or dark box, and no movement. On a phone feed it is less common, because captions sit over busy video and compete with the app's buttons. If you want it anyway:
- In an editor that lets you choose fonts, set Arimo, Roboto or Inter in a medium or bold weight, white, with a soft shadow or a semi-transparent black box.
- Keep lines to about 42 characters on landscape video, Netflix's own limit, and shorter on vertical video.
- Use sentence case and normal punctuation; the subtitle punctuation and capitalization post has the rules.
Where CapsAI's styles differ
CapsAI doesn't have Netflix Sans, and you can't upload a font: each of its 37 caption styles comes with its own font. It also has no switch for static subtitles that appear and disappear as whole blocks, so it can't reproduce the Netflix look exactly. The nearest options:
- Base (free) is the plainest style: white Inter in a heavy cut, with no outline or box. It sets every word in capitals, and words appear as they are spoken.
- Tommy Soft (free) and Story (free) keep the whole caption on screen in the case you typed. Tommy Soft puts cream text on dark rounded pills; Story uses a warm white book serif. Both highlight the spoken word in color, which Netflix subtitles never do.
- Newsroom (free) is the closest to a broadcast look: white capitals on black boxes, with the spoken word in yellow. More box styles are on the subtitles with a black background page.
If you want yellow rather than white text, the why are subtitles yellow post covers when it helps and how to set it.
What to do next
Decide whether you want the streaming look or a social look. For the first, use a desktop editor with Arimo or Roboto. For the second, upload a clip and compare the plain and boxed styles on the caption styles page. New accounts get 3 free minutes, packs start from $4 (₹49 in India, €4 in the euro area), and watermark-free export comes with every paid pack.
