YouTube Shorts size and aspect ratio

YouTube Shorts are vertical and full-screen, using the familiar 9:16 ratio, commonly produced at 1080 × 1920 pixels. A Shorts cover differs from a standard video thumbnail in one important way: it largely appears on the Shorts shelf and in autoplaying loops, where viewers catch it for a fraction of a second before scrolling past. A single clear subject that reads instantly — not a busy collage — performs far better.

Because Shorts are watched full-screen on phones, the right edge of the frame carries the action buttons in most mobile layouts. Keep your subject centered and clear of that right-side rail.

How to resize an image for YouTube Shorts

  • Upload or drag and drop an image into the tool.
  • The Shorts preset (9:16) is pre-selected on this page.
  • Adjust the crop with the rulers or the corner handle.
  • Preview in the Shorts mockup, checking the mobile view.
  • Export in your preferred format.

YouTube Shorts safe zone

The Shorts player places its action buttons — like, comment, share, and the channel avatar — in a rail along the right edge, with the caption and username near the bottom-left. That right rail is the main safe-zone concern: keep names, faces, and text clear of roughly the right 15% of the frame and off the bottom caption area. The central band is the safest spot for critical detail.

After you CUT the image, tap the See how it looks button to preview your still inside a realistic Shorts mockup. Use the mobile view to confirm your subject reads well near the screen edges.
