Steam Capsule Art Tips for Indie Games

Steam capsule art is the cover image that represents your game in search results, in store lists and on your store page. A good capsule has one clear subject, strong contrast with its background and a logo that survives every crop. Players usually see it at thumbnail size before they see anything else, so the art has to work when it is small.

This guide covers what makes a capsule readable, how to test each size and the mistakes that show up most often in indie projects. It is written for teams with a game in development who want a store page that looks sharp from the first scroll.

Why does capsule art matter so much?

Most players first meet your game as a small image in a list, a search result or a recommendation strip. At that size, fine detail disappears, and the image has a moment to communicate genre and mood. Art that looks great full screen can turn into a blur once it is shrunk.

Thumbnail size is also where layout mistakes become obvious. A logo near the edge can disappear in one crop, and a busy background can hide the subject entirely. Those problems rarely show up when you look at the full-size file.

What makes a capsule readable?

Give it one clear focal point

Choose one subject: a character, a weapon, a creature or a single location. Place it where the eye lands first, and give it the most contrast in the frame. If two things compete for attention, the thumbnail shows neither.

Use contrast between subject and background

Convert your capsule to grayscale and look at it. If the subject disappears when color is removed, the contrast is too weak. Lighting, a darker backdrop or a rim light can separate the subject from the scene.

Keep text to a minimum

Your logo does most of the work. A logo with a clear silhouette reads far better than a tagline, and a short phrase only works if it is large enough to read at thumbnail size. Skip paragraphs of text entirely.

How do you test every capsule size?

Export every capsule type you need from the start, not just the largest one. Then run this check on each size:

1. Scale the image to its real display size and view it at arm's length on your monitor.
2. Ask someone who has not seen the game to name the genre after one glance.
3. Check the logo in every crop, because a crop can cut off letters or the edge of a word.
4. Look at the result on a bright background and a dark one to see how the edges hold up.
5. Compare all sizes side by side, so the set reads as one game and not a collection of unrelated images.

What mistakes should you avoid?

Most of these show up in many indie capsules, and each one is easy to fix before you publish.

• Using a screenshot with the interface still visible. Menus and HUD elements turn into noise at small sizes.
• Putting the logo near an edge, where a crop can remove it.
• Writing text that is only readable at full size.
• Changing the art style between capsule types, so the set does not feel like one game.
• Using the main menu, a loading screen or an empty environment with no subject.
• Placing text over busy detail with no backdrop behind it.

How does capsule art fit with the rest of your page?

A capsule works best when it matches the trailer, the first screenshots and the short description. A player who clicks from a thumbnail expects the store page to show the same game. Consistency also helps returning visitors spot your game quickly in a crowded list.

Your capsule also appears wherever a player is deciding whether to follow your game, so plan it alongside the demo and the page. The Steam demo strategy guide explains how a playable demo supports that decision, and the Steam page checklist for VR games lists the other pieces that should match your capsule.

How do capsule styles fit different genres?

Each genre has its own visual shorthand, and your capsule should fit what its audience expects. A horror game often uses darkness, a single figure and a sharp light source. A rhythm shooter may lean on bold color and motion lines. A co-op game may show a group, since players want to see the shared experience. Study the top titles in your genre on the store and note what they have in common. Then find a way to match that signal while keeping your own look.

Which mistakes come from copying too closely?

Copying another game's capsule can backfire. Players may mistake your game for the original, and the store may treat it as a weak imitation. Use the genre shorthand, but make your subject, palette and logo specific to your own project. Test your capsule next to two or three competitors and ask whether the difference is clear within a second. If your capsule blends in, change the subject or the palette before you publish.

Where should you check the current sizes?

Valve updates store graphics from time to time, so treat the official documentation as the source of truth. Check the Steamworks partner documentation for the current capsule types and dimensions before you export final files. Note the date you checked, since the rules can change between projects.

Before you lock the art, shrink your capsule to thumbnail size and look at it for a few seconds. If the subject and genre read at a glance, you are close. Export the full set, check the logo in every crop, and get a second pair of eyes on it before you publish.
