What a feature graphic is for
On Google Play, the feature graphic is the wide banner at the top of a listing. Google shows it only when the listing also has a promo video — it becomes the video's poster frame — and in some editorial placements. If you publish your web app as a Trusted Web Activity and add a YouTube promo, you need one; if you don't add a video, it is still required by the form but rarely seen.
Outside Play, the same 1024×500 image is a good hero for your install page and, cropped, a social header. Designing it once for both saves effort.
Spec
- 1024 × 500 px, exactly. JPEG or 24-bit PNG (no alpha).
- Play overlays a play button in the centre when a video is present — keep the middle clear of text.
- Play crops the edges on some screen sizes; keep essential content inside the central 80% horizontally.
- Don't repeat the app icon at large size — the listing already shows it directly below. A small icon plus a headline reads better.
- Google's metadata policy applies: no ranking claims, no "#1", no award badges you cannot substantiate, no pricing that could go stale.
What to put on it
One benefit, five to seven words, in a type size that survives being shrunk to 300 px wide on a phone listing. A subline is optional and should be smaller. The gradient background should use your brand colours — the palette extractor gives you the hex codes — with enough contrast that white text is legible over the whole area, including the lighter end of the gradient.
For a web app specifically, the headline can carry the differentiator that store apps can't claim: "Installs in one tap. No app store." That line does work on an install page.
Reusing the export
| Use | Size | From the 1024×500 export |
|---|---|---|
| Play feature graphic | 1024×500 | Use as is |
| Open Graph image (link previews) | 1200×630 | Regenerate — different ratio; the social kit has the preset |
| Install page hero | Any wide ratio | Use as is, or export at 2× for retina by upscaling the source icon first |
| Twitter/X header | 1500×500 | Regenerate in the social kit |
