YouTube's current guidance recommends a 1:1 aspect ratio because Community post images appear square in the feed. It does not specify one required resolution. A 1600 × 1600 pixel image is a strong high-resolution preset, while 1080 × 1080 produces a smaller square file.
Landscape images such as 1280 × 720 are useful when you are reusing a thumbnail-style design. Vertical images such as 1080 × 1350 can work for portrait content, but keep faces, logos, and text away from the edges in case the preview is cropped differently on mobile.
For most creators, square images are the safest choice. YouTube accepts JPG, PNG, GIF, and WebP images up to 16 MB. See the official YouTube Community post guidance.
| Use case | Recommended size | Why |
|---|---|---|
| Best default | 1600 x 1600 | High-resolution square with room for compression. |
| Smaller upload | 1080 x 1080 | Good balance for mobile viewers and smaller files. |
| Thumbnail reuse | 1280 x 720 | Works for 16:9 designs, but square is safer in feed previews. |
| Portrait artwork | 1080 x 1350 | Useful for vertical art; keep text away from edges. |
