Game icons, game passes and badges are 512x512 (1:1). YouTube thumbnails for Roblox videos are 1280x720 (16:9), under 2 MB.** Those three numbers cover almost every case. The table below has the rest — minimums, formats, and where each image actually shows up. Last verified against [Roblox Creator Hub publishing docs](https://create.roblox.com/docs/production/publishing) on September 17, 2026. ## Every Roblox image size | Image | Recommended size | Ratio | Format | Notes | | --- | --- | --- | --- | --- | | Experience (game) thumbnail | 1920x1080 | 16:9 | PNG or JPEG | Minimum 768x432. Up to 10 per experience. | | Experience (game) icon | 512x512 | 1:1 | PNG | Shown around 150x150 in the games feed — design for small. | | Game pass icon | 512x512 | 1:1 | PNG | Cropped square in the store list. | | Badge icon | 512x512 | 1:1 | PNG | Displays as a circle on the badge list. | | Developer product icon | 512x512 | 1:1 | PNG | Same square as the game pass icon. | | Group logo | 512x512 | 1:1 | PNG | Cropped to a circle on the group page. | | Decal / image asset | Up to 1024x1024 | Any | PNG or JPEG | Roblox rescales to a power of two, so 1024x1024 is the safe ceiling. | | Experience banner / cover | 1920x1080 | 16:9 | PNG or JPEG | Same upload as the experience thumbnail — Roblox has no separate banner size. | | YouTube video thumbnail | 1280x720 | 16:9 | PNG or JPEG, under 2 MB | YouTube's rule, not Roblox's. 1920x1080 downscales cleanly. | | Profile picture (Discord, TikTok, YouTube) | 512x512 or larger | 1:1 | PNG, transparency supported | All three crop to a circle — keep the head off the edges. | ## Which size should I export? These get mixed up constantly, and uploading one into the other's slot is why so many experiences have a stretched or cropped tile. Pick the slot first, then the pixels: - **Game icon — 512x512.** The square tile in search, the games feed, and your profile. One per experience. Design for about 150x150 on screen. - **Experience thumbnail — 1920x1080.** The wide gallery image on the experience page. Up to ten per experience; the first one is the cover. - **YouTube thumbnail — 1280x720.** YouTube's rule, not Roblox's, and the file must stay under 2 MB. A 1920x1080 render downscales cleanly. See [YouTube's thumbnail specs](https://support.google.com/youtube/answer/72431). ## Why the exact ratio matters Roblox crops or letterboxes anything that is not the expected aspect ratio. A 16:10 render uploaded as a thumbnail loses a strip off the top and bottom — usually your character's head. A rectangular image uploaded as an icon gets squeezed into a square. Render at the ratio you need rather than cropping afterwards. If you want headroom for a later crop, render 3840x2160: that is still 16:9, and it downscales to 1920x1080 without softening. ## Design rules that survive small sizes - **One focal point.** A single character mid-action reads better than three ideas crammed into one tile. - **Contrast between subject and background.** A rim light or an outline around your character is what makes it pop at feed size. - **Test at 150x150.** That is roughly how big your icon actually is in the feed. Text that is unreadable there is text nobody reads. - **Keep detail out of the corners** on anything circular — badges, group logos, and every profile picture. ## Export and upload checklist In the [Renderbux studio](/p/new), load your avatar by username, pose and light it, then pick the export preset that matches the table: 16:9 at 1920x1080 or 4K for thumbnails, 1:1 at 512x512 for icons, game passes and badges. PNG export supports transparency, so you can drop the render onto any background afterwards. 1. **Pick the aspect ratio first.** Choose 16:9 for an experience thumbnail or a YouTube thumbnail, and 1:1 for a game icon, game pass, badge or profile picture. Getting the ratio right up front is what stops Roblox cropping your render. 2. **Render at the recommended size.** Export 1920x1080 for 16:9, or 512x512 for 1:1. Rendering larger — 4K at 16:9 — is safe and downscales cleanly. 3. **Save as PNG under 2 MB.** PNG preserves hard edges and text, and supports transparency if you plan to composite the render onto another background. Keep the file under 2 MB so Creator Hub and YouTube accept it. 4. **Check it at display size.** Shrink the image to roughly 150x150 for an icon, or to the width of a feed tile for a thumbnail. If it is illegible small, it is illegible. 5. **Upload it in the right slot.** In Creator Dashboard, open your experience, then Configure — the icon and thumbnail slots are separate uploads. Wait for moderation; it usually clears within a few minutes. ## FAQ **What size is a Roblox thumbnail?** 1920x1080 pixels at a 16:9 aspect ratio. That is the recommended size for an experience thumbnail. Roblox accepts a minimum of 768x432, but 1920x1080 looks noticeably sharper on modern displays, and anything off 16:9 gets cropped or letterboxed. **How big is a Roblox thumbnail?** 1920x1080 pixels — about 2.1 megapixels, and typically well under 2 MB as a PNG. It is displayed much smaller than that in the games feed, so the design has to survive being shrunk. **What is the Roblox thumbnail aspect ratio?** 16:9 for experience thumbnails, and 1:1 (square) for icons. Export at the exact ratio: Roblox crops or letterboxes anything else, which is how thumbnails end up with heads cut off or black bars down the sides. **What size is a Roblox game icon?** 512x512 pixels at a 1:1 aspect ratio, uploaded as a PNG. Note that it is often displayed near 150x150 in the games feed, so keep the design readable at that size. **What is the Roblox game banner size?** 1920x1080 pixels at 16:9 — the same as the experience thumbnail. Roblox does not have a separate banner or cover upload; the first thumbnail is the cover that shows on the experience page. **Is the Roblox icon the same size as the thumbnail?** No — and mixing them up is the most common upload mistake. The icon is the square 512x512 tile that represents your experience in the feed. The thumbnail is the 16:9 1920x1080 image in the gallery on the experience page. Each experience has one icon and up to ten thumbnails. **What size is a Roblox game pass or badge icon?** 512x512 pixels, 1:1, same as the experience icon. Badge icons are displayed as circles, so keep important detail away from the corners. **What resolution should a Roblox thumbnail be?** 1920x1080 is the sweet spot. You can render at 4K (3840x2160) — still 16:9 — and it downscales perfectly, which is worth doing if you plan to crop into the image later. **PNG or JPEG for Roblox thumbnails?** PNG for anything with text, outlines, or hard edges, which is most thumbnails. JPEG is fine for purely photographic scenes. Keep files under 2 MB either way so they load fast. **What size should a Roblox YouTube thumbnail be?** 1280x720 pixels (16:9), under 2 MB, as a PNG or JPEG. This is YouTube's standard rather than Roblox's, but it is the size most Roblox video creators actually need. ## Related - [How to make a Roblox thumbnail](/guides/how-to-make-a-roblox-thumbnail) - [Roblox thumbnail maker](/make/roblox-thumbnail) - [Roblox game icon maker](/make/roblox-game-icon) - [Roblox YouTube thumbnail maker](/make/roblox-youtube-thumbnail) --- Source: https://www.renderbux.com/guides/roblox-thumbnail-size · Renderbux · Independent tool, not affiliated with Roblox Corporation.
