Style Guidelines

Style guideline sample courtesy of DCMP
Like newspapers, magazines, or any other published product, good captions follow a style guide. If you plan to produce more than a few captioned videos, a consistent style will go a long way to adding polish, readability, and clarity to your captions.
Common style conventions include:
- All capital letters vs. mixed, or sentence case (mixed case is the preferred style for web work)
- Limit of lines of text per screen (usually two or three)
- Whether to spell out numbers
- Whether to italicize foreign words
- When to wrap text to the next line (not in the middle of a prepositional phrase, for example)
The Described and Captioned Media Program (DCMP), funded by the US Department of Education, has published a “Captioning Key” that serves as a good baseline for captioning style guides. See the Resources section for more information.
