YouTube image sizes
- Thumbnail: 1280×720 pixels, 16:9. YouTube accepts JPG, PNG or GIF up to 2 MB, at least 640 pixels wide.
- Channel banner: 2560×1440 pixels. On phones only the central ~1546×423 pixel strip is guaranteed to show, so keep text and logos there.
- Profile picture: 800×800 pixels, displayed as a circle.
If the file is still over 2 MB after resizing, run it through Compress image or save it as JPG.
Tips for a thumbnail that gets clicks
A raw screenshot from the video rarely works. Pick a sharp, high-contrast frame, a close-up face and at most 3–5 words of big text (use Add text to image). If the photo isn't 16:9, Fill crops the edges and Fit pads it with a blurred background.

Frequently asked questions
What size should a YouTube thumbnail be?
1280×720 pixels at 16:9, no more than 2 MB.
Why can't I upload a custom thumbnail?
Your YouTube account has to be verified (by phone) in YouTube Studio first.
Is 1920×1080 OK?
Yes, YouTube accepts and downsizes it, but 1280×720 gives a smaller file that safely stays under the limit.
