YouTube Thumbnail Size, Canvas and Export Checklist
Published by Influence
Last checked
YouTube currently recommends 3840 × 2160 pixels for video thumbnails and 2160 × 3840 pixels for Shorts thumbnails. Use a 16:9 landscape layout for videos and 9:16 for Shorts. File-size limits depend on the upload device, so check both the dimensions and the file you plan to upload.
These recommendations come from YouTube’s custom-thumbnail help, reviewed on October 15, 2026. A thumbnail should accurately represent the video and remain understandable when displayed much smaller than the exported image.

What are the current YouTube thumbnail requirements?
| Use | Recommended dimensions | Important condition |
|---|---|---|
| Video thumbnail | 3840 × 2160 px; 16:9 | Minimum width: 640 px. |
| Shorts thumbnail | 2160 × 3840 px; 9:16 | Minimum height: 640 px; custom upload through desktop Studio. |
| Video thumbnail uploaded on mobile | Use the video dimensions above. | File must remain under 2 MB. |
| Video, Shorts or podcast thumbnail uploaded on desktop | Use the format appropriate to the content. | File must remain under 50 MB. |
| Podcast playlist thumbnail | Square; 1:1 | Mobile limit: under 10 MB. |
YouTube lists JPG and PNG as example image formats and requires a verified account for custom thumbnails. A 1280 × 720 landscape image is still 16:9 and exceeds the stated minimum width, but it is no longer the current recommended resolution. Review the upload message if your account or device offers different controls.
How do you use the downloadable thumbnail canvas?
Import the editable 3840 × 2160 SVG canvas into a design application. Add your own image and optional headline, remove the group named guides when you no longer need its rule-of-thirds lines, and export a JPG or PNG for upload. The SVG is an editing source, not a file format this guide promises YouTube will accept as a thumbnail.
- Choose one clear subject that represents the actual video.
- Use a short readable heading only when it adds information beyond the image.
- Keep essential details away from the outer edges and leave room around the subject. This is a design precaution, not a guaranteed platform safe zone.
- View the image at a small preview size before export. If the idea disappears, simplify it.
- Check the exported dimensions, format and device-specific file size.
- Preview the thumbnail with the actual title; together they should make one accurate promise.
Is a YouTube banner the same size as a thumbnail?
No. A channel banner is a separate image. YouTube recommends 2560 × 1440 pixels, with a minimum of 2048 × 1152 and a file no larger than 6 MB. At the minimum canvas, its stated text-and-logo safe area is 1235 × 338 pixels. The banner crops differently across devices. YouTube’s channel-branding requirements
Do not apply the minimum-canvas safe-area number to a larger canvas without scaling it proportionally. Use the channel upload preview to inspect computer, mobile and television presentation. A finished thumbnail’s composition is rarely a useful banner without redesigning the layout.

What does a completed thumbnail plan look like?
Fictional example
Fictional video: Cedar Desk’s guide to checking a desk footprint. This is a design plan, not a performance result.
Type: landscape video thumbnail uploaded through desktop Studio. Canvas: 3840 × 2160 px, 16:9.
Composition: an overhead illustration of a desk footprint marked on a floor; one chair shape shows the additional space needed.
Heading: “Will this desk fit?” The video demonstrates that exact question; the image does not imply a room transformation absent from the footage.
Export plan: JPG. Check the actual exported file is under the desktop 50 MB limit; prepare a separate under-2 MB version if uploading from mobile.
Review: inspect the subject and heading at a small preview size, confirm all details match the video and check the uploaded result. No click-through improvement is assumed.
What should you check if a thumbnail looks wrong?
First check the actual exported file, not just the design document. Look for the wrong aspect ratio, a low-resolution source stretched onto a large canvas, excessive compression, or tiny text. If upload succeeds but the image is not immediately visible, allow for processing rather than repeatedly replacing it. A different preview surface can also crop an image differently.
Finish the video package with the YouTube description template. For a consistent publishing experiment, use the YouTube posting-time guide. Clear design and accurate packaging support the viewer’s decision; neither guarantees traffic.
