About this style
Rounded Box places your subtitle text inside a semi-transparent rounded rectangle. This creates excellent contrast against any background, making it one of the most popular choices for social media content. The box smoothly wraps around the text and adapts to different line lengths.

Great for outdoor or busy-background videos where plain text would get lost.
The box color adapts to your chosen accent color - try matching it to your brand.
Pairs well with both portrait (9:16) and landscape (16:9) formats.
How it differs from other styles
Unlike Regular or Minimalist, it adds a visible background box. The rounded corners give it a modern look compared to classic rectangular subtitle boxes. Message Box uses a chat-bubble shape instead of a symmetric rectangle.
