Why 120×45 is the size that matters
Valve says the small capsule "should contain readable logo, even at smallest size", which usually means the logo nearly fills the frame. Search results and lists show your game at 184×69 or even 120×45, so a thin script logo or a busy collage turns to mush. If it reads at 120×45, it'll read everywhere.
What you're allowed to put on a capsule
Only your game's artwork and logo. Valve's rules ban review quotes, award laurels, discount text and "out now" banners on base capsules; use Artwork Overrides for time-limited messages. Read more in our Steam capsule sizes and art guide.
