# YouTube Thumbnail Size and Dimensions

The recommended YouTube thumbnail size, aspect ratio and the five sizes YouTube generates, plus design tips that hold up on small screens.

By Finoraa · Updated November 2, 2026

## Key takeaways

- Upload thumbnails at 1280 × 720 pixels in a 16:9 shape.
- The minimum width is 640 pixels.
- YouTube generates up to five sizes from your upload.
- Keep text short and the bottom-right corner clear.

## Recommended size

YouTube recommends a 1280 × 720 thumbnail with a 16:9 aspect ratio and a minimum width of 640 pixels. Larger files are scaled down, and other shapes are cropped or padded.

## Sizes YouTube generates

| Name | Size | File |
| --- | --- | --- |
| Maximum | 1280 × 720 | maxresdefault.jpg |
| Standard | 640 × 480 | sddefault.jpg |
| High | 480 × 360 | hqdefault.jpg |
| Medium | 320 × 180 | mqdefault.jpg |
| Small | 120 × 90 | default.jpg |

## Design tips

- Use a clear subject and strong contrast.
- Keep text to a few large words.
- Leave the bottom-right corner empty, where the video length appears.
- View the design at thumbnail size on a phone before uploading.

## Common mistakes

- Tiny text that cannot be read in search results.
- Busy backgrounds that hide the subject.
- Uploading a small image that looks blurry when enlarged.
