# navigation.maxZoom

Part of [Navigation bar](https://kernstra.com/docs/web-sdk/config/navigation) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `number`
- Default: `8`

Largest zoom they reach; past the last preset the buttons step by a quarter. Text and vector art stay sharp up to it: a page bitmap is bounded by [`performance.maxRenderPixels`](https://kernstra.com/docs/web-sdk/config/performance/maxrenderpixels), and past that the part in view is drawn again at full resolution over it.
