Roblox Game Icon Size: The Complete Guide

Your icon is the smallest piece of art in your experience's marketing, and the one players see the most often — in search results, on charts, in their friend list, and pinned to their home screen. A thumbnail gets one big moment on the homepage; an icon gets seen dozens of times a session, almost always small. Here's the exact spec and how to make it hold up at the sizes it actually renders.

The short answer

Roblox game icons are square, and the upload size is 512×512 pixels.

That 512×512 source gets scaled down to as small as 150×150 wherever Roblox shows a compact icon — charts rows, search suggestions, the mobile app grid. Whatever you design, judge it at that smaller size, not the canvas you drew it on.

Uploading at the full 512×512 matters even though most renders are much smaller, for the same reason a high-resolution thumbnail matters: Roblox generates every smaller crop from your source file. A soft, low-resolution upload stays soft no matter how it's resized down; a sharp 512×512 source gives every downstream size — 150×150 included — the cleanest possible starting point.

Design for 150×150, not 512×512

An icon that looks crisp at full resolution can turn into a smear of color the moment it's shrunk to a chart row or a home-screen tile. Icons render small far more often than they render large, so design for the small case first:

• One subject. A single character, mascot, or object reads at a glance; a full scene doesn't.
• Minimal or no text. Text is usually the first thing to become illegible at 150×150 — if you need a title, put it on your thumbnail, not your icon.
• High contrast. A bold silhouette against a simple background survives being shrunk; fine detail and low-contrast art don't.

A useful test: shrink your working file down to a thumbnail-sized preview in whatever tool you're using and look at it from across the room, or squint at it on your phone. If you can't tell what it is at a glance, a player scrolling past a chart row won't either. Icons that pass this test tend to share the same short list of traits — a simple color palette (two or three colors, not a gradient-heavy scene), a subject centered rather than cropped at the edges, and an outline or silhouette strong enough to read even if every internal detail were removed.

Icon vs thumbnail

Icons and thumbnails do different jobs, and mixing them up is one of the most common Roblox marketing mistakes:

Your icon is your persistent brand mark — players recognize it the same way across charts, search, and their friend list, so it should change rarely, if ever. Your thumbnail is a pitch, swapped and tested to see what earns a click. See the Roblox thumbnail size guide for the full 16:9 spec.

Treating the two as interchangeable is a common shortcut — cropping a square from the middle of a 16:9 thumbnail and calling it the icon, or stretching a square icon out to 16:9 for the thumbnail slot. Both produce art that was composed for a different shape, so the crop cuts off part of the subject and the stretch distorts it. Design each for its own frame from the start.

Preview your icon at real size

Guessing whether an icon reads at 150×150 from a 512×512 canvas in your design tool is unreliable — you need to see it the way players actually will. The tool's Charts view renders square icons in place, next to real neighboring experiences, at realistic size, so you can judge legibility the same way a player scrolling a chart would, rather than zoomed into your editor at 100%.

FAQ

What size is a Roblox game icon?

512×512 pixels, square. Roblox scales it down to as small as 150×150 across charts, search, and the app, so design with that smaller size in mind.

Can the icon and thumbnail be the same image?

No — they're different aspect ratios. An icon is square (1:1) and a thumbnail is widescreen (16:9). Uploading the same image as both means one of them gets stretched to fit the wrong shape, distorting your art either way.
