Video aspect ratios explained: planning 16:9, 9:16, 1:1 and 4:5

Match the frame to the viewing context

Landscape 16:9 remains common for websites, presentations and long-form video. Vertical 9:16 fills a phone held upright. Square 1:1 and portrait 4:5 can use more feed space in some placements. Platform options change, so verify current specifications during delivery.

Choose formats based on where the audience will encounter the work and how the story behaves there. Do not add a version simply because it is available if there is no distribution plan for it.

Decide between protected framing and separate setups

Some scenes can be composed with the subject and product inside a central area that supports several crops. This is efficient for simple demonstrations or single speakers, but it can make a landscape frame feel unnecessarily empty.

Wide groups, lateral movement and detailed environments may need dedicated vertical coverage. Mark these scenes in the shot list and schedule time to adjust camera position, performance or blocking.

Protect text and interface-safe areas

Social interfaces can cover the top, bottom and sides of a video. Keep essential titles, captions, logos and product information away from those areas based on the current placement. Review test exports inside the actual platform workflow when possible.

Text that is readable on an edit monitor may be too small on a phone. Use concise language, sufficient contrast and enough display time. Burned-in captions and platform-native captions each have advantages; decide which versions are required.

Edit for attention, not only shape

A shorter vertical cut may need a different opening and faster context than the main landscape film. Preserve the core meaning while adapting the sequence to how the viewer encounters it. Do not assume cropping the master creates an effective social edit.

Record alternate hooks and calls to action when the brief requires them. Keep clean shots long enough for different edit rhythms, and capture room around important actions so reframing does not feel cramped.

Create a deliverables specification

• Destination and placement for each asset.
• Aspect ratio, resolution and maximum duration.
• Opening hook, message and call to action.
• Caption method, language and text-safe area.
• Thumbnail or cover-frame requirement.
• Approval owner and publication date.

Store the specification with the creative brief and update it when the media plan changes. The production and distribution teams can then make the same assumptions instead of discovering conflicting requirements at export.
