About Simplified Chinese subtitling

Sixteen characters a line, nine a second

A Simplified Chinese subtitle line holds 16 characters, against the 42 a Latin-script line is given. That is not a meaner allowance. Unicode classes Han ideographs as wide, meaning each one takes a full em where a Latin letter takes half — so sixteen of them and forty-two English letters occupy roughly the same strip of screen, and a word processor that reports the line as short is measuring the wrong thing.

The reading speed is a real reduction, though. Platform style puts Simplified Chinese at up to 9 characters per second on adult programming and 7 on children's, where a Latin-script file runs to 17. SDH gets a little more room, 18 characters and 11 per second, because descriptors and speaker labels have to fit somewhere. Shorter line, slower read: the text has to be condensed twice over.

That condensing is the work, and it is why the file is written rather than converted. At GoLocalise a native Simplified Chinese subtitler drafts it, a second linguist reads it, and the line count is measured in full-width positions rather than trusted to a character counter before anything is signed off.

Which do you need?

Open captions, closed captions or SDH

Three different deliverables that people often ask for by the wrong name. Here is the short version.

Open captions

Burnt in

Subtitles burnt permanently into the picture. Nobody can switch them off, which is exactly what you want for social feeds that autoplay muted — and in Chinese it fixes the full-width spacing in the image, so no player can reset it.

  • Always visible
  • Full-width spacing fixed in the image
  • Delivered as a finished video file

Closed captions

Switchable

A separate file the viewer can turn on and off, and that can carry several languages at once. The standard for YouTube, Vimeo and the streaming platforms.

  • Viewer controls them
  • Multiple languages from one video
  • Indexed by search engines

SDH

Accessibility

Subtitling for the deaf and hard of hearing: dialogue plus speaker IDs and the sound effects and music cues that carry meaning.

  • Speaker identification
  • Non-dialogue audio described
  • Meets accessibility requirements

Subtitles or captions? The two terms are often used interchangeably. Strictly, subtitles translate the dialogue for viewers who can hear the audio, while captions are same-language and add speaker labels and sound cues for viewers who cannot. We produce either — translated Simplified Chinese subtitles or same-language Simplified Chinese captions and SDH — in whichever form your platform and audience require.

What we subtitle

Simplified Chinese subtitling for every kind of content

Short product and explainer videos captioned to lift conversion and reach.

How can we help you?

Your project manager has everything covered

One point of contact from brief to delivery, and both a linguistic and a technical check on every file.

1

Brief review

We review your video, your audience and the player, including whether its character counter treats one Han ideograph as a single position or as two.

2

Template and translation

Where needed, we create an English subtitle template first, then send it to a native Simplified Chinese subtitler.

3

Timing and quality checks

Subtitles are timed against the video and checked for reading speed, line length in full-width positions, punctuation to platform style, and format compliance.

4

Delivery and display check

Files delivered in the format you need, with the character widths and the spacing confirmed on screen rather than assumed.

Our standards

The specs we work to

Readable subtitles are a matter of measurable limits, not opinion. These are the defaults we apply to Simplified Chinese unless your style guide says otherwise.

16characters

Maximum per line

Eighteen on SDH lines

2lines

Maximum on screen

One line unless it overflows

9chars/sec

Reading speed

Seven on children's programmes

1second

Minimum duration

Seven seconds maximum

The count is what briefs get wrong. Sixteen and forty-two describe the same width of screen, because a wide character takes a full em and a Latin letter half of one, so a Chinese line is not a shorter line. The reading speed is the genuine cut: nine a second against seventeen. We condense to fit both, then confirm it in a player instead of a spreadsheet.

Simplified Chinese specifics

The punctuation a Chinese subtitle drops on purpose

Platform style is explicit about it: do not use commas or periods, use one single space instead. An event does not close with a full stop and a clause boundary is shown by a gap rather than by a mark. The enumeration comma survives inside a list, written A、B、C, though never at the end of a line or of a subtitle. A translated document poured straight into a timing tool arrives carrying every mark that convention removes.

Widths then have to hold steady across the line. Numerals stay half-width (1, 2, 3 rather than their full-width twins), so a price, a date or a model number is typed as you would type it in English, while the ellipsis is the single character U+2026 instead of three stops in a row. Mixing the two widths inside one subtitle is the sort of thing a Chinese reader registers immediately, even when every word is correct.

None of this is decorative, and it is what our second pass is reading for: the gap where a comma would have gone, the unterminated line, the stray full-width digit. We check it event by event. If the file you send turns out to be written in traditional characters we will say so rather than convert it quietly, because that readership has wording of its own.

Most common questions

Why does a Simplified Chinese line stop at 16 characters when English gets 42?

Because the two counts describe the same width. Unicode treats Han ideographs as wide characters, each filling a full em against the half em a Latin letter takes, so sixteen of them stretch about as far across the frame as forty-two English letters do. The limit is a measurement of the picture rather than a restriction on the language, which is why counting code points misleads you.

Is it correct that Chinese subtitles carry no commas or full stops?

It is the convention platform style sets out. Where a comma belongs, the subtitle takes a single space, and the event closes without a full stop. Enumeration commas are kept inside lists, written A、B、C, but not at the end of a line or subtitle. To a Chinese audience it reads as ordinary. To anyone checking it against an English script it can look like missing punctuation.

Do the numbers and symbols have to be full-width as well?

Only some of them. Numerals stay half-width, so a date, a price or a product code is typed the way it would be in English. The ellipsis is one character, U+2026, rather than three separate stops. Get the widths mixed inside a line and nothing breaks technically, but the spacing looks uneven to a reader and it is one of the first things QC flags.

How much has to be cut to reach nine characters a second?

More than most briefs expect. Nine a second on adult programming, seven on children's, and eighteen characters with eleven a second once you move to SDH. The line and the rate come down together, so a dialogue-heavy scene needs rewriting rather than trimming. That is a translation skill, and it is why a native subtitler drafts these rather than an automated pass.

What does it cost to subtitle a video into Simplified Chinese?

Simplified Chinese subtitling is priced by the minute of running time, from £20. Condensing into the sixteen-character line and applying the punctuation conventions sits inside that rate rather than beside it. The figure moves with programme length, whether a transcript is needed first, an SDH pass, a burnt-in master and the number of delivery formats. Every job is quoted individually under our Price Match Promise.

Our footage is already in Mandarin. Can you caption it without translating?

That is a good share of the work here. Same-language Chinese captions and SDH are what an accessibility brief asks for and what keeps a video working with the sound off. The sixteen-character line, the reading speed and the punctuation conventions apply exactly as they do to a translated file, and a transcript comes first either way.

We already hold a Chinese SRT. Can you build on it?

Usually, yes. We spot and time against your picture from what you send, re-break any line running past sixteen positions and clear out the commas and full stops a translated document brings with it. Should the file turn out to be in traditional characters, we flag it rather than convert it blindly: our Traditional Chinese subtitling page covers that readership.

Which editing software are your subtitle files compatible with?

All the common ones. Our SRT, VTT, STL and TTML files carry the Chinese text and the full-width marks intact into Premiere Pro, Final Cut Pro, DaVinci Resolve and the major online editors, and we confirm each renders before delivery. Where a team would rather not handle a sidecar file at all, we hand back a finished MP4 or MOV with the text already in the picture.
