Which size to use

YouTube recommends 3840 × 2160 for video thumbnails, a 16:9 image at 4K, with a minimum width of 640 pixels. Thumbnails can be JPG or PNG, up to 50 MB from a desktop or 2 MB from a phone. If you upload from your phone, the 1920 × 1080 preset saved as JPG makes a much lighter file at the same ratio.

Shorts thumbnails are vertical: 2160 × 3840 (9:16), at least 640 pixels tall. On some surfaces, a vertical video with a 16:9 custom thumbnail gets an auto-generated 4:5 thumbnail instead.

The channel banner is 2560 × 1440 (16:9), the size YouTube recommends with TVs in mind. The minimum upload is 2048 × 1152, and on that size the safe area for text and logos is the central 1235 × 338. Banners must be 6 MB or smaller. Profile pictures render at just 98 × 98, but an 800 × 800 upload stays sharp.

YouTube video limits

The resizer handles still images. For video, these are the limits to plan around.

Tips for YouTube images

  • Download thumbnails as JPG. Photos make much smaller JPG files than PNG ones.
  • Check your thumbnail at a small size too, since that is how most people first see it.
  • Use Fit with background to build a banner from a square logo, with your brand color filling the sides.
  • Profile pictures can be JPG, GIF, BMP or PNG up to 15 MB, but not animated GIFs.
