Aspect ratio affects composition, text size and attention. A professional campaign adapts the layout to each format rather than simply cropping the same frame.
Vertical and portrait formats
9:16 suits full-screen vertical viewing, while 4:5 provides more height in portrait feeds. Both require large text and a central subject.
Square and landscape formats
1:1 provides a balanced social post, while 16:9 suits landscape video and presentation-style viewing. Wider frames allow more environmental context.
A product scene may use a wide environmental shot in 16:9 but a closer centred composition in 9:16.
Protect safe areas
Interface controls, captions and platform overlays can cover edges. Keep important logos, faces, products and actions within a safe central area.
Limitations and responsible review
Platform specifications can change, and supported output formats depend on the connected service.
Generated scripts, media and recommendations should be checked against the approved business information, source assets, rights, platform policies and intended audience before professional use.
Conclusion
Choose formats according to viewing behaviour, then deliberately recompose each approved scene.
