# radius

The distance provided in meters or the longest distance derived from the center point to the region’s bounding box.

```
get radius(): number;
```

## Discussion

When fetching points of interest with a region, you may compare this value with [`MaxRadius`](/documentation/MapKitJS/PointsOfInterestSearch/MaxRadius) to determine if this region is larger than the maximum available radius for a points-of-interest search.
