Roblox recommends 1920×1080 pixels at a 16:9 aspect ratio for experience thumbnails. The Creator Hub says uploaded thumbnails are stretched to 16:9 if the source uses another ratio; thumbnails uploaded through Home Page personalization must stay under 3MB.
- •Export at 1920×1080 so Roblox does not need to stretch a non-16:9 source.
- •Keep essential text and faces out of the bottom edge where metadata may appear.
- •Preview several active thumbnails at small sizes before starting Roblox's personalization test.
What you need to know
Experience thumbnails appear on Roblox's Home page and at the top of an experience detail page. Roblox calls 1920×1080 the ideal high-resolution upload and supports JPG, GIF, PNG, TGA and BMP images.
The ratio matters as much as the resolution. Roblox states that displayed thumbnails are stretched to 16:9 when the uploaded image uses another aspect ratio, so a correctly sized source avoids distortion.
Keep essential text and artwork away from the bottom edge. Roblox warns that metadata such as player count can cover that area, and its thumbnail policies require imagery to represent the actual experience rather than advertise unavailable content.
