The right size is simple: 16:9.

Build at 1920×1080 when possible, keep the final image sharp, and preview it at the small size where players make their first decision.

Recommended Roblox thumbnail dimensions

For a Roblox experience thumbnail, the most useful working format is 1920×1080 pixels. That is a 16:9 aspect ratio, so the composition maps cleanly to modern game discovery cards and to forgeplace placements.

Quick size reference

  • 1920×1080: best working size for a detailed thumbnail.
  • 1280×720: a lighter 16:9 working option.
  • 768×432: a compact 16:9 preview size.
  • 16×9 units: the smallest forgeplace placement ratio.

Why aspect ratio matters

A thumbnail can be technically large and still look wrong if the composition is not 16:9. A mismatch can crop a face, cut off a UI element, or leave empty space around the action. Design the crop first, then add the details that support it.

Export checklist

Use PNG for crisp graphic elements and JPG when the image is photographic or very large. Check that the file opens correctly, that text remains readable at small size, and that the image has a descriptive filename such as roblox-obby-thumbnail-1920x1080.jpg.

The forgeplace wall uses 16:9 units across a 99,993,600-pixel canvas, so a game thumbnail stays in the same visual language from your Roblox page to your placement.

Thumbnail size FAQ

Is 1920×1080 a good Roblox thumbnail size?

Yes. It gives creators a sharp 16:9 master file that can be resized for smaller discovery surfaces without changing the composition.

Can I use a square Roblox icon as a thumbnail?

Use a square icon for your experience identity and a 16:9 thumbnail for the larger discovery image. They serve different jobs.
