The right caption style makes a video feel polished and keeps eyes on screen. The wrong one covers faces, clashes with your brand, or is simply hard to read on a small phone. Here's how to choose.
Start with the platform
Vertical short-form platforms (TikTok, Instagram Reels, YouTube Shorts) reward energetic, large captions placed in the middle third of the screen. The bottom of the frame is usually covered by the app's own interface — usernames, descriptions and buttons — so captions placed too low get hidden.
Horizontal video on YouTube, LinkedIn or a website suits calmer, cinema-style subtitles near the bottom, where viewers expect them.
- Vertical (9:16): position captions around 60–75% from the top.
- Horizontal (16:9): position captions around 82–90% from the top.
- Keep important text away from the far left and right edges.
The six styles and when to use them
- Bold Pop — heavy uppercase font, thick outline, 2–4 words at a time with the active word highlighted. Best for talking-head clips, tips and storytelling on TikTok and Reels.
- Karaoke — the line fills with colour word by word as it's spoken. Great for tutorials, music, quotes and anything where pacing matters.
- Cyber Neon — glowing monospace text. Works for gaming, tech, nightlife and edgy brands; use sparingly on busy backgrounds.
- Boxed — dark text on a solid colour block. The most readable option on bright, busy or changing footage.
- Classic — white text with a black outline and gentle fade. The safe choice for interviews, documentaries and long-form YouTube.
- Minimal — smaller, quieter text with a soft shadow. Ideal for premium, lifestyle or aesthetic content where the footage is the star.
Size: bigger than you think
Most people watch on a phone held at arm's length. On vertical video, captions at around 7–10% of the frame height are comfortable to read. For horizontal video, 5–7% usually looks right. If you need to squint at your own preview on a laptop, it's too small for a phone.
Words per caption
Showing an entire sentence at once is fine for slow, horizontal content. For short-form, fewer words per screen feels faster and more dynamic. Three words is a popular sweet spot for Bold Pop; five or six works well for Karaoke because the highlight already guides the eye.
Use the "Words per caption" slider in TheTextFlow's Style tab to switch between short punchy chunks and full sentences.
Colour and contrast
Readability beats creativity. White or yellow text with a dark outline is readable on almost any footage. If you use your brand colour, use it for the highlight rather than all of the text. Avoid thin fonts with no outline over bright skies, snow or white walls.
Stay consistent
Once you find a style that works, use it for every video. A consistent caption look becomes part of your brand — regular viewers will recognise your content in the feed before they even see your face.
