Thumbnails

Thumbnails appear on Roblox's Home page and at the top of your game's detail page, allowing you to showcase your game's features and announce updates or events.

You can feature up to 10 images or videos for each of your games' detail pages. All uploaded images and videos are moderated to make sure they adhere to the Community Rules and Terms of Use.

Manage thumbnails

Uploaded thumbnails appear in the Experience Detail Page tab where they can be reordered, deleted, or given "alt" text for improved accessibility.

Images

A thumbnail image should be 16:9 aspect ratio and ideally 1920×1080 pixels so that it always displays in high resolution across the Roblox site and app. Supported formats include .jpg, .gif, .png, .tga, or .bmp. See best practices for additional design recommendations.

To upload an image thumbnail for your game:

1. In the Creator Dashboard, select the game you want to upload an image thumbnail for.
2. Go to Configure ⟩ Places and select a place.
3. Click Thumbnails in the left nav, then use the Home Page tab and the Experience Detail Page tab to customize your game's thumbnails for these two spaces.

Videos

To help users understand your game before they join, you can upload an authentic gameplay video. Once approved, the video will appear first on your game's detail page, and it can also be shown on the Home page.

To upload a video thumbnail for your game:

1. In the Creator Dashboard, select the game you want to upload a video for.
2. Go to Configure ⟩ Places and select a place.
3. Click Videos in the left nav.

Video thumbnails should be authentic and accurately portray in-game content without misleading alterations. All videos will be reviewed to ensure they accurately reflect the game and do not violate the Community Rules or Terms of Use.

Certain modifications are acceptable, as long as they don't misrepresent the core game:

To prevent misleading players, please adhere to the following policies. Videos which do not adhere to these policies will be rejected for distribution and count against the monthly quota of 3 video uploads.

Free camera mode

Studio's free camera mode is a useful tool to capture in-game screenshots and videos because it allows you to move the camera to vantage points which may not be possible through the default view camera. To enable free camera mode:

1. Go to a game where you have server-side Developer Console access.

2. Initiate a solo playtesting session.

   

3. Press Left Shift and P.

Once in free camera mode, you can use the following controls:

Home page personalization

Thumbnail personalization helps you attract more users to your game by showing the most relevant thumbnail to each user on their Home page. The goal of thumbnail personalization is to improve your qualified play through rate, which is the percentage of users that actively engage with your game for a significant amount of time.

Thumbnail personalization only starts when you activate 2 or more thumbnails. If only one of your thumbnails is active, all users see that thumbnail for your game on their home page.

After you set up and activate thumbnail personalization, its algorithm shows each thumbnail to a random set of users to get data on the qualified play through rate for each user group. It then gives more impressions to the winning thumbnail for each group, but still gives the other thumbnails minimal traffic to continue exploration.

Set up thumbnail personalization

To set up thumbnail personalization:

1. In the Home Page tab, click Edit active thumbnails.
2. Upload new thumbnails or activate existing thumbnails.

   • To upload new thumbnails, click Upload thumbnails and select and confirm the images you want to use. Make sure to keep these images under 3MB and 1920×1080 pixels.
   • To activate existing thumbnails, enable the Active checkbox next to 2-5 thumbnails.
3. Click Save changes.
4. In the Start new thumbnail personalization? dialog, click Start. The banner in the Home Page tab updates to indicate that thumbnail personalization is active.

Keep multiple thumbnails active

For example, if you had removed the thumbnail associated with the green line in the chart below too early, you would have missed future additional impressions for what ended up becoming your second-best performing thumbnail.

It's recommended to test multiple new thumbnails with any major game or content update, and then not make changes to your thumbnails until your game's next update.

Analyze thumbnail personalization performance

After a few hours, the Thumbnail Performance table in the Home Page tab populates with statistics related to each of your active thumbnails:

You can also use the Impressions by thumbnail and the Qualified play through rate by thumbnail graphs to further analyze the performance of your personalized thumbnails over time.

Best practices

To create the most positive impact for players looking to play your game, consider the following best practices.

Quality and aspect ratio

A thumbnail image should be 16:9 aspect ratio and ideally 1920×1080 pixels so that it always displays in high resolution across the Roblox site and app. Displayed thumbnails will be stretched to 16:9 aspect ratio regardless of the upload's aspect ratio.

Relevant content

A thumbnail will have a higher impact if it's unique and provides relevant imagery on what players should expect when they join the game. Thumbnails with ambiguous imagery or graphics may lead to unnecessary confusion.

Video accuracy

Video thumbnails should be authentic and portray actual in-game content without misleading alterations.

Theme and color

You can express your game's theme through overall theme and colors to help players decide if it's suitable and appealing to them.
