> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).

Page shape a page template is designed for.

**Signature:**

```typescript
export type PublisherPageFormatV1 = "widescreen" | "a4Portrait" | "letterPortrait";
```

## Remarks

A layout's geometry only reads correctly at the proportions it was authored for: a row of three visualizations that works on a widescreen page is unusably narrow on an upright page. The format is therefore a property of the page, not a choice made when rendering it.
