Roblox thumbnail ideas by game type
Players read the genre before the title. Match what top games in your genre already do, then make it about your game.
Pet simulator
A giant pet or egg is the hero, with a small avatar for scale, a bright sky and a rainbow or outlined title. Most top simulators look like this.
Tycoon
Show what players get to own: the factory, the mansion, the piles of cash. Put a proud avatar in front and make TYCOON part of the title.
Brainrot
Crowd the frame with the meme creatures players collect, add a huge money-per-second number, and catch the avatar mid-steal.
+1 per click
Show before and after: tiny on one side, gigantic on the other, with +1 popups between. The headline says exactly what each click gives.
Horror
One light source, shadowy figures with glowing eyes and a scared avatar in front. Keep the text short, dark and cracked.
Anime fighting
Anime key-art lighting, energy effects and two fighters clashing, with a stylized logo in a corner.

How to make a Roblox game thumbnail that gets plays
What works on the Roblox Home page.
- 1Start from your own game. Upload a screenshot so the cover shows your real map and characters. It converts better and stays within Roblox’s rules on representing your game.
- 2Pick one idea. A giant pet, a rarity number, a boss fight. One clear hero reads at thumbnail size; a busy scene doesn’t.
- 3Title up top, three words max. Your game name or the update (“NEW WORLD OUT!”) in the top half, big and outlined.
- 4Make several and let Roblox test them. Activate 2–5 thumbnails on the Home page tab. Roblox shows each to different players and favors the winner; in its tests, games gained 8.5% more qualified plays on average.

Questions
What size should a Roblox game thumbnail be?
1920×1080 pixels at a 16:9 aspect ratio. Roblox stretches every thumbnail to 16:9, so other shapes get distorted. RoThumbnail downloads game covers at exactly 1920×1080.
Will Roblox accept an AI-made thumbnail?
Roblox moderates every thumbnail and wants it to show what players will actually find in your game. Start from a real screenshot of your experience so the cover stays true to it, and avoid promo text like “50% off”.
How many thumbnails can my game have?
Up to 10 images or videos on your game’s detail page. For the Home page, activate 2 to 5 thumbnails so Roblox can test which one gets more plays.
Where does the title text go?
Keep titles in the top half. Roblox can cover the bottom of a thumbnail with details like the player count.
Is a Roblox game cover the same as a thumbnail?
Yes. Roblox calls the 16:9 images on your experience page thumbnails; players and creators often call the main one the game cover. Both are 1920×1080. The square image next to your game name is the icon, a separate 512×512 upload.
Can I turn an image into a Roblox game thumbnail?
Yes. Upload a screenshot or any image of your game (PNG, JPG or WebP) and it becomes the base: your map and characters stay, and the lighting, drama and title are added.
