Generate thumbnails using Ask Studio
Use Ask Studio to get suggestions on custom thumbnails for your videos. Ask Studio analyses your video's transcript and themes to suggest thumbnails that are tailored to your video.
To generate a thumbnail:
- Open Ask Studio within your publishing workflow.
- Enter a prompt like 'Create a thumbnail'.
- To get suggestions for a specific video, type '@' to open a pop-up menu and search for or select your video. For example, you can type 'Create a thumbnail for @' and then select the video that you want to generate a thumbnail for.
- Use follow-up prompts to make any changes.
- For example, you can prompt Ask Studio to make the text on your thumbnail larger.
- Review the generated suggestions.
Custom thumbnail best practices
Image size and resolution
Your customised thumbnail image should be as large as possible. It will be used as the preview image in the embedded player. We recommend that your customised thumbnails:
- Have a resolution of 3840 x 2160 pixels (with minimum width of 640 pixels).
- Be uploaded in image formats such as JPG, GIF or PNG
- Remain under MB limits. Limits depend on the device that you're using to upload your thumbnail:
- Mobile: 2 MB for video thumbnails or 10 MB for podcasts.
- Desktop: 50 MB for both video thumbnails and podcast thumbnails.
- Try to use a 16:9 aspect ratio as it's the most used in YouTube players and previews.
- For podcast playlists, upload a thumbnail with an aspect ratio of 1:1 instead of 16:9.
Note: Vertical videos with 16:9 custom thumbnails will be replaced by an auto-generated 4:5 thumbnail on the home, explore and subscription pages. Your custom thumbnail will still appear on the watch feed, watch history and non-mobile platforms.
Thumbnail policies
All customised thumbnail images must follow our Community Guidelines. Your thumbnails may be rejected and a strike placed on your account if it contains:
- Nudity or sexually provocative content
- Hate speech
- Violence
- Harmful or dangerous content
Repeat offences may lead to the removal of your custom thumbnail privileges for 30 days or even account termination. Learn more about Community Guidelines strikes.
If a strike is issued, you'll get an email and see an alert in your channel settings the next time that you sign in to YouTube. You can appeal the strike if you think that your thumbnails don't violate the YouTube Community Guidelines. If your appeal is approved and you haven't already replaced the thumbnail, we may restore it.
Customised thumbnail limits
There's a limit to how many custom thumbnails a channel can upload each day. If you get an error saying 'Daily custom thumbnail limit reached' when trying to upload a thumbnail, try again in 24 hours.
Limits may vary by country/region or channel history. Copyright strikes may impact channel history eligibility. Community Guidelines strikes will affect how many customised thumbnails you can upload.
Note: You can't upload a custom thumbnail for Shorts like you can with long-form videos. You can select a frame from your Short to use as the thumbnail that appears in search results, hashtag and audio pivot pages, and your channel page. Once selected, you can't change the thumbnail after uploading the video.
Why are my customised thumbnails turned off?
YouTube may turn off customised thumbnails for certain search results when they're considered inappropriate for viewers.
