Roblox Thumbnail Size & Dimensions

Roblox experience thumbnails use a 16:9 aspect ratio. Get the dimensions right and your thumbnail displays crisp and uncropped everywhere it appears: the games list, search, and your experience page.

  • Aspect ratio: 16:9 (widescreen)
  • Recommended size: 1920 x 1080 pixels
  • Minimum size: 1280 x 720 pixels
  • Format: PNG or JPG
  • Thumbnails per experience: up to 10, so you can test and rotate winners

Every thumbnail from this tool is generated at the correct 16:9 ratio and high resolution, so there is nothing to crop or resize before you upload.

How to Create a Roblox Thumbnail

2

Add Reference Images

Optionally upload screenshots from your game or reference art to help the AI match your game's style and aesthetic.

Generate & Use

Get your thumbnail in seconds. Download and upload to your Roblox game page, or use for social media and advertisements.

How to Make High-CTR Roblox Thumbnails

A great thumbnail is the difference between a scroll and a click. Use these proven tips when writing your prompt so the AI produces thumbnails players actually tap.

Lead with a bold character or face

Thumbnails with a clear, expressive character stop the scroll. Show emotion: excitement, shock, or determination reads instantly at small sizes.

Keep text short and readable

One or two punchy words at most. Use a heavy, high-contrast font so the words survive being shrunk down in the Roblox games list.

Use high contrast and saturated color

Bright, saturated colors and strong light-vs-dark contrast make your thumbnail pop next to competitors in the same genre.

Show the core fantasy of your game

The thumbnail should promise what makes your experience fun in a single glance: the tycoon empire, the epic boss, the obby finish line.

Avoid clutter

A busy thumbnail turns to mush at thumbnail size. One clear subject and a clean background almost always beats a crowded scene.

Frequently Asked Questions

What size should a Roblox thumbnail be?

Roblox displays experience thumbnails in a 16:9 aspect ratio. 1920 x 1080 pixels is the recommended size, though any 16:9 image (such as 1280 x 720) works. Upload as a PNG or JPG. Every thumbnail from this tool is generated at the correct 16:9 ratio, so you can download and upload it directly.

How do I make a Roblox thumbnail with AI?

Describe the scene you want: the action, characters, environment, and mood. Optionally upload screenshots from your game as reference so the AI matches your style. Generate, then download the finished 16:9 thumbnail in seconds. No design skills or software required.

How do I make my thumbnail get more clicks?

The highest-CTR Roblox thumbnails lead with a bold, expressive character, use one or two words of high-contrast text, and show the core fun of the game in a single glance. Because generating is fast and cheap, the real edge is testing several thumbnails and keeping the one that converts.

Can I use my own game screenshots as a reference?

Yes. You can upload reference images (screenshots, character models, or existing art), and the AI will match your game's style and aesthetic. Reference image limits depend on your plan.

Can I use the thumbnails commercially?

Absolutely. Every thumbnail you generate includes a full commercial license. Use it on your Roblox game page, in sponsored ads, and across social media, including for monetized experiences.

How much does it cost to make a thumbnail?

Thumbnails cost 3 credits at 1K resolution (4 at 2K, 5 at 4K), just cents per generation. New users can verify their Discord to claim free credits and test the tool before committing to a plan.
