| Requirement | Value |
|---|---|
| Recommended size | 1280 × 720 px |

| Aspect ratio | 16:9 |
| Max file size | 2 MB |

YouTube accepts thumbnails as small as 640×360, but they'll look blurry on high-DPI screens. Always target 1280×720 for sharp results on retina displays and large monitors.
The bottom-right corner of your thumbnail is covered by YouTube's timestamp label in search results, so keep faces, text, and important visuals away from that area.
