YouTube Shorts Aspect Ratio: 9:16, Square Video and Export Checks

Plan a Shorts canvas by reading 9:16, 1:1 and 16:9 as width-to-height ratios, separating YouTube eligibility from RavenCut's supported format, and checking the exported frame with a fillable worksheet.

Understand 9:16 and YouTube Shorts eligibility

No. A 9:16 frame is a useful portrait canvas, but it is not the only shape that can qualify as a Short. An aspect ratio compares width with height, so 9:16 means nine units wide for every sixteen units tall — a tall, portrait frame. YouTube's current guidance describes eligible square or vertical uploads as Shorts under its upload-date and channel rules, so a square 1:1 upload can also be in scope. Treat 9:16 as a deliberate design choice for phone-first viewing, not as a universal platform requirement, and do not assume that any upload will be categorized or monetized as a Short.

Compare vertical, square and landscape layouts

All three describe the same idea — width compared with height — but they change how much room a scene has. The table below uses pixel pairs to show the arithmetic of each ratio; the numbers illustrate the math and are not mandatory platform resolutions or a statement about RavenCut output.

Layout Example pixel pair Reduced ratio Orientation Planning effect
Vertical 1080 x 1920 9:16 Portrait Tall frame; a wide scene must be cropped or letterboxed
Square 1080 x 1080 1:1 Square Balanced frame; neither tall nor wide emphasis
Landscape 1920 x 1080 16:9 Landscape Wide frame; a tall subject needs side bars or a crop

Crop and bars are the two conceptual answers to a mismatch. Cropping keeps the frame filled but discards part of the original image; bars keep the whole image but leave empty space. Decide which one your scene can tolerate before you generate anything, because a wide establishing shot and a tall subject fail in opposite directions.

Choose the RavenCut Short format before generation

The workflow supports 9:16 Shorts and 16:9 long-form videos; free accounts are limited to Shorts. Choose the 9:16 Short format at the start of the creation workflow rather than planning a landscape scene and hoping to reshape it later. For the full production path — source, script, scene review and upload — follow the guide to create an original YouTube Short from a script. If you are adapting existing footage instead, see how to repurpose YouTube videos into Shorts.

Verify the exported frame with an original checksheet

Open the actual exported file, read its real width and height, reduce the pair to a ratio, and compare that with the canvas you planned. Then watch it on a phone-sized screen to confirm the subject and any text stay readable. The worksheet below turns that into a repeatable pass.

Hypothetical worked example: correcting a mismatched landscape plan

This is a hypothetical video-planning example, not a tested customer result.

Before

A fictional creator plans a Short about tidying a desk. The scene list reads: "Opening: wide shot of the whole desk, 1920 x 1080, caption across the bottom." The plan assumes a landscape frame even though the destination is a phone-first Short.

After

"Opening: tall shot of the desk edge and the hand reaching in, 1080 x 1920, caption stacked in two short lines near the middle of the frame." The scene list now names the portrait canvas, the subject is chosen to fill a tall frame, and the caption is planned for a narrow width.

Why the change matters

A wide desk shot squeezed into a tall frame either loses its edges to a crop or gains empty bars. Rewriting the scene around a tall subject keeps the frame purposeful, and planning the caption as stacked short lines avoids a long single line that a narrow frame cannot hold. The numbers here are illustrative arithmetic, not a required resolution.

Export-check worksheet

Fill one row per export. Copy the blank row for each new file.

  • File name: ______
  • Intended destination (for example, a Shorts upload): ______
  • Measured width in pixels: ______
  • Measured height in pixels: ______
  • Reduced ratio (divide both by their greatest common factor): ______
  • Orientation (portrait / square / landscape): ______
  • Planned canvas for this scene: ______
  • Does the measured ratio match the plan? (yes / no): ______
  • If no, what will change — the scene, the crop, or the bars?: ______
  • Phone-screen check: is the main subject readable without zooming? (yes / no): ______
  • Phone-screen check: is any caption fully inside the frame? (yes / no): ______
  • Reviewer initials and date: ______

Worked rows for the three ratios, using the illustrative pixel pairs from the comparison table:

  • 1080 x 1920 reduces to 9:16, portrait — matches a planned vertical Short canvas.
  • 1080 x 1080 reduces to 1:1, square — a square plan, not a 9:16 plan.
  • 1920 x 1080 reduces to 16:9, landscape — a mismatch if the plan was a vertical Short; correct the scene or accept bars.

Boundary

This worksheet checks geometry and readability; it does not decide whether a video will be treated as a Short. Creator judgment still governs scene choice, caption wording and whether a crop is acceptable for the story.
