How to Add Captions to Reels and Shorts That People Actually Read
Captions keep people watching when the sound is off and help them follow fast speech. But badly placed captions get covered by app buttons or are too small to read. Here is how to do them properly.
Two kinds of captions
App captions are added inside Instagram, TikTok or YouTube. They are quick, but you have little control over style, and they don't travel with the file when you post elsewhere.
Burned-in captions are part of the video itself. They look the same on every platform, can match your brand, and can highlight words. Most creators who post the same clip in several places use burned-in captions.
Rules for readable captions
- Size: big enough to read at arm's length; about 6–8% of the frame height for 9:16.
- Contrast: white or yellow text with a dark outline or shadow works on any background.
- Line length: two to five words per line, one or two lines at a time.
- Placement: slightly above the bottom third, away from the app's own text and buttons.
- Timing: captions should change with the speech, never a full sentence early.

Start freeUsing SRT files
An SRT file is a plain text file with timestamps and lines of text. You can export one from most transcription tools, then import it into your editor to style it. In Pixtale Edits you can import an .srt, pick one of the caption styles and fonts, and translate the captions into another language.
Word highlighting
Highlighting the current word in a second colour, like yellow, guides the eye and makes fast speech easier to follow. Use it for punchy clips; for calm, educational clips, plain captions can feel more premium.
Step by step: burned-in captions
- Get a transcript with timestamps from a transcription tool and export it as .srt.
- Import the .srt into your editor and check it against the audio. Fix names, numbers and brand words; transcription often gets them wrong.
- Choose a style: font, size, colour, outline or box, and where the captions sit.
- Turn on word highlighting if the clip is fast or energetic.
- Preview on your phone before you export.
Caption styles that work
Bold outline: white text with a thick black outline. Works on any background and is the most readable. Box: text on a semi-transparent dark box; clean and calm, good for educational content. Highlight: current word in a brand colour; energetic and popular for podcasts. Minimal: small lower-case text; looks premium but only works on simple backgrounds. Pick one style for your brand and keep it consistent, so people recognise your clips before they see your name.
Captions in other languages
If part of your audience speaks another language, translated captions can open a new market without recording anything new. A Hindi or Hinglish podcast with English captions reaches viewers outside India; an English podcast with Spanish or Hindi captions reaches new viewers too. Keep translated lines short, because some languages need more words for the same idea.
Captions and accessibility
Captions also make your content accessible to people who are deaf or hard of hearing, and to anyone watching in a noisy place. Accurate captions with correct speaker words are part of making content for everyone, not only a growth trick.
FAQ
Do captions really increase views?
They help retention, because people who watch on mute can follow along. Retention is one of the strongest signals for Reels and Shorts.
What font is best for Reels captions?
Bold, simple sans-serif fonts such as Montserrat or Anton read best on small screens.
Can I translate captions?
Yes. Translate the caption text, then burn it in, or export separate SRT files per language.
