Planned result

9:16 centered crop

1,214 × 2,160 px

Approximately 68.4% of source pixels fall outside the centered crop.

Formula or method

Centered crop = largest target-aspect rectangle that fits inside the source

Assumptions

  • The crop is centered and does not detect faces or subjects.
  • Keep titles and essential visuals away from the outer edges.

How to use the crop preview

Calculate the largest centered crop that converts a source frame into a common destination aspect ratio. The result quantifies geometry only; it cannot decide whether a face, product, caption, or graphic remains meaningfully composed.

Read the crop as a composition warning

A 3840 by 2160 landscape frame converted to 9:16 keeps a narrow centered slice and removes most source pixels from the sides. Use the calculated crop dimensions to build a guide layer, then inspect the actual shot rather than assuming the center is the correct focal point.

Keep important text, faces, logos, and calls to action away from platform-interface regions. Safe areas vary by destination and can change, so verify the current publishing interface with a private test instead of treating one overlay as permanent.

Choose reframing, padding, or a new layout intentionally

A centered crop works when the subject already occupies the destination area. Otherwise move the crop window, animate a pan, use a split layout, rebuild graphics, or record a dedicated vertical angle. Padding preserves the full source but may reduce useful screen area.

The percentage outside the crop describes source pixels, not perceived quality. A tight crop can still look sharp when the source has enough resolution, while a mathematically large crop can fail because the important action occurs near an edge.

Common questions

Questions about this tool

Does the planner move the crop to follow a subject?

No. It calculates a centered crop. Reposition or animate the crop manually when the focal point is elsewhere or moves through the shot.

Why are so many pixels removed for vertical video?

Landscape and vertical frames have very different aspect ratios. Filling a 9:16 frame from 16:9 source requires removing a large portion of the left and right sides.

Is adding black bars better than cropping?

It depends on the content and platform. Padding preserves the entire frame, while reframing uses more screen area. Compare readability and composition in the real destination.
