YouTube image sizes (2026)
| Format | Size (px) | Ratio | Used for |
|---|---|---|---|

| YouTube Channel Art | 2560×1440 | 16:9 | Channel art across all devices |
Why exact sizes matter on YouTube
YouTube requires thumbnails of at least 1280×720 (16:9) under 2 MB, and channel art at 2560×1440 with only a small “safe area” visible on every device. Exporting exact sizes keeps thumbnails sharp in search results and channel art intact on TV, desktop, and mobile.
