Caption Sizes

What are caption sizes?​

Caption size controls how large subtitles appear on the video.

In ReelBot, caption size is not cosmetic — it directly affects:

  • readability on mobile
  • visual balance with B-roll
  • viewer retention in short-form content

Caption size is selected in the Video Settings Sidebar.

Available caption sizes​

ReelBot currently supports three caption sizes:

Small​

  • compact
  • minimal visual presence
  • less screen coverage

Best for:

  • visually dense B-roll
  • cinematic content
  • experienced audiences
  • subtle branding

Medium (default)​

  • balanced readability
  • moderate screen presence
  • optimized for most use cases

Best for:

  • general short-form content
  • mixed visuals
  • most creators and brands

This is the recommended default.

Large​

  • highly readable
  • strong visual emphasis
  • maximum accessibility

Best for:

  • fast-paced speech
  • mobile-first audiences
  • educational or motivational content
  • viewers watching without sound

How caption size affects layout​

Caption size influences:

  • line height
  • number of words per line
  • how captions interact with visuals

Larger captions:

  • reduce words per line
  • increase vertical space usage

Smaller captions:

  • allow more visual room
  • require slower pacing to remain readable

Caption size vs caption timing​

Caption size does not affect:

  • timing
  • word highlighting
  • speech synchronization

Timing is controlled by:

  • voiceover
  • speech marks

Size controls presentation, not synchronization.

Changing caption size safely​

You can change caption size:

  • at any time
  • without regenerating content
  • without consuming AI credits

Caption size changes are applied at render time.

Caption size and brand presets​

If a brand preset is applied:

  • caption size still remains configurable
  • colors and highlighting come from the brand
  • size is controlled independently

This allows flexibility without breaking brand consistency.

Accessibility considerations​

Larger captions improve:

  • accessibility
  • comprehension
  • retention for non-native speakers

If your content is:

  • instructional
  • motivational
  • information-dense

Larger captions generally perform better.

Common mistakes to avoid​

  • using small captions with fast speech
  • using large captions on visually minimal videos
  • changing caption size mid-batch
  • compensating for pacing issues with size changes

Caption size should match speech rhythm — not fix it.

Best practices​

For consistent results:

  • choose one caption size per batch
  • test on a mobile screen
  • favor readability over subtlety
  • save successful setups as templates

Caption size consistency builds familiarity.

The CreatorOps perspective​

In CreatorOps, captions are part of the delivery system.

Caption size controls how easily your message is absorbed — not what the message is.

ReelBot treats caption size as a first-class layout decision, not an afterthought.

  • Speech Marks & Caption Accuracy
  • Video Settings Sidebar
  • Brand Presets
  • Accessibility & Retention

Readable captions aren’t optional — they’re foundational.
