How to Enable Custom Thumbnails on YouTube in 2024
August 28th, 2023 by Terri Pinyerd

The only requirement for uploading custom thumbnails is verifying your YouTube account. You can do this via the YouTube Verification page here.


Along with this, it's important to ensure that your channel is free from copyright strikes and/or community guideline violations, as this could result in your channel losing access to key features.


How To Upload Custom Thumbnails

You can add a custom thumbnail (or update the current thumbnail) to any of your YouTube videos via the desktop site or mobile device using the instructions below.


NOTE: After updating an existing thumbnail it may take some time for the changes to reflect on your YouTube channel.


Via Desktop


  1. Sign in to YouTube Studio.
  2. From the left menu, select Content.
  3. Click the video.
  4. Click Upload Thumbnail. Choose an image from your device.
  5. Click SAVE on the top right corner.


Via Mobile


  • From the YouTube app, tap Library > Your Videos
  • Next to the video of your choice, tap More > Edit > Edit Thumbnail
  • Tap Custom Thumbnail to select an image from your device.
  • Tap SAVE.


IMPORTANT: If you've uploaded a 16:9 custom thumbnail to a vertical video, it will be replaced with an auto-generated 4:5 thumbnail on the home, explore, and subscription pages. However, your custom thumbnail will still appear on non-mobile YouTube as well as the watch feed and watch history areas.


YouTube Thumbnail Creation Tips

In order to make your thumbnail selection and creation process as smooth as possible, there are a few guidelines and tips to keep in mind.


Recommended Size For Thumbnails On YouTube


The ideal size for a YouTube thumbnail is 1280w x 720h pixels. While this might seem unusually large, it ensures that your thumbnail is as crisp as possible when shrunk down to thumbnail size.


Best Image Formats For YouTube Thumbnails


Stick with JPG or PNG for the best clarity and resolution.


Adhering To Content Guidelines


When designing your thumbnail, be sure to avoid misleading images (like clickbait) and stick to the community guidelines. This means no adult content or imagery, depictions of violence or dangerous activity, or hate speech.



Benefits Of Using A Custom Thumbnail

On YouTube custom thumbnail images are one of the most effective elements of a successful video, but unfortunately they're also one of the most overlooked.


A strong thumbnail increases the chances that a viewer will be interested in your YouTube video enough to click on it, watch it, and (hopefully) engage with your content. In other words, video thumbnails are your first shot at enticing prospective viewers and increasing your click-through rate (CTR).


Generally, viewers will be drawn to the following elements of a video, in order:


  • A video's thumbnail

  • A video's title

  • The video description

  • The view count


If these elements satisfy the viewer, they will then click on your video. How long they stick around for will depend on the quality of your content and the established engagement levels (views, likes, and comments). You can learn more about how to keep viewers engaged to increase your watch time here.
