YouTube thumbnail size requirements

  • Size: 1280 × 720 pixels (minimum width 640 pixels)
  • Aspect ratio: 16:9
  • File size: under 2 MB
  • Formats: JPG, PNG or GIF (non-animated)

The bottom-right corner is covered by the video length, so keep text and faces away from it. Thumbnails are often seen very small on phones - big, bold text of three or four words works best.

Frequently asked questions

What is the best YouTube thumbnail size?
1280 × 720 pixels at a 16:9 ratio. It displays sharply everywhere, from phones to TVs.
Why is my thumbnail being rejected?
The most common reason is a file over 2 MB. Download as JPG at 85-90% quality to stay well under the limit.
Can I use a 1920 × 1080 image?
Yes, it is the same 16:9 shape and YouTube will scale it down, but 1280 × 720 is smaller and uploads faster.
