title: “Publishing formats” description: “Named formats for the platforms you publish to — pick one instead of typing an aspect ratio by hand.”
A format preset is a stored publishing format — “Instagram Reels is 9:16, capped at 900 seconds” — that you reach by naming the platform and placement instead of typingaspect_ratio and duration yourself. There are
21 presets across 7 platforms,
covering post content (feed, story, reels, video placements) as well as
profile and page identity assets (logos, banners, channel art).
You can name a preset in the Playground or Workflow Studio’s format control,
or ask the agent for a platform by name ("make this for Instagram Reels")
and it sets the preset for you. The control groups every preset by platform:
What picking a format actually does
A preset sets an intent, not a fixed request. Two things follow from that:- An explicit value you set still wins. If you set
aspect_ratioyourself alongside a format preset, your explicit value is used — the preset only fills in what you didn’t specify. - When the model you picked can’t produce the preset’s exact ratio, the
closest one it can produce is used instead, and the substitution is
reported back to you (as the
x-infery-param-adjustmentsresponse header over the API, or as a badge on the message in the Playground) so you always know what you actually got.
Cover and banner formats need an extra step today
Three formats in the table below — LinkedIn’s profile cover (4:1), LinkedIn’s
company page cover (189:32), and X’s profile header (3:1) — are wider
than any image model can generate natively. No model in the catalog declares
those ratios, so today they resolve to the closest ratio a model can
produce — in practice, 16:9 — and you get a wide rectangle, not a true
banner. The substitution is reported the same way as any other format
substitution, so it won’t be a silent surprise, but the result on its own is
not yet a usable banner: it needs a crop or pad step afterward to reach the
format’s real dimensions. Until that step is available in your workflow,
treat a cover/banner preset as a starting image to crop, not a finished asset.

* YouTube — Channel art: the full 2560 × 1440 canvas is not all guaranteed visible — only the centered 1546 × 422 “safe zone” survives every device’s crop (phone, desktop and TV each crop it differently outside that area), so don’t put anything you need seen near the edges.

Dimensions marked
— for max duration are image formats and have no
duration. Duration ceilings shown here are the platform’s own published
limit; the model you generate with may offer a shorter maximum, in which
case the shorter one applies.
