Roblox thumbnail templates for stories, challenges and flexes
Seven looks for how Roblox YouTube really packages videos: Brookhaven stories, rich vs poor, horror, top 10 lists, anime combat, pet flexes and 24 hour challenges.
Pick a look to open it in the Roblox studio with the style already loaded.

By format
A look for each Roblox video type
Roblox is a thumbnail-first feed. The frame has to tell the story before the title does, and each format tells it a different way.
- +Brookhaven Drama: the twist, the reveal, the face in the middle
- +Rich vs Poor: two sides of the screen, one obvious contrast
- +Roblox Horror: one threat, lots of dark, a scared reaction
- +Top 10 / List: the number, the ranking, the winner on top
- +Blox Fruits / Anime Combat: hero pose and a big hit of impact
- +Pet / Adopt Me Flex: the rare pet, up close
- +I Spent X Challenge: the time or the money, as big as the player
Your avatar
Your avatar, your game, your story
Bring your avatar and a frame from the game. The look builds the thumbnail around them. Plenty of Roblox channels never show a face, and the studio works the same for them. If you want a real reaction, Characters places your face and Expression sets the mood.
- +Start from a look or describe the scene yourself
- +Add screenshots from the game as references
- +Fix a face, the lighting or a messy background without redoing the rest
- +Remaster a thumbnail you already posted
Brookhaven
Brookhaven stories need one clear beat
The best Brookhaven thumbnails show a single moment: the transformation, the jumpscare, the family fight. Pick the beat, put it in the frame and give it two or three words.
- +One beat per thumbnail, not the whole plot
- +The reaction face carries it (yours or your avatar's)
- +Short text in caps, not a sentence
- +Contrasting colors to split the good side from the bad
Keep it loud
Roblox thumbnails can be loud on purpose
Bright colors, big shapes and exaggerated faces are the norm in this feed. Keep it simple so it still reads small.
- +Big avatar, big face, big text
- +High contrast between subject and background
- +One number at most, and only if it's the hook
- +Don't bury the game name in a corner
