# aroundRadius

<Setting type="integer | &#x22;all&#x22;" default="null" scope="search" />

The `aroundRadius` parameter defines the **maximum distance (in meters)** from the central location within which results are returned.
Used with [`aroundLatLng`](/doc/api-reference/api-parameters/aroundLatLng) or [`aroundLatLngViaIP`](/doc/api-reference/api-parameters/aroundLatLngViaIP),
this limits how far from the center Algolia will retrieve results.

## Usage

* Applies only to radial searches around a location.
* Works only when \[`aroundLatLng`] or \[`aroundLatLngViaIP`] is set.
* The [Geo ranking criterion](/doc/guides/managing-results/refine-results/geolocation) must be in your ranking formula (included by default).
* If omitted, Algolia dynamically calculates the radius based on result density.
* To enforce a minimum radius, use [`minimumAroundRadius`](/doc/api-reference/api-parameters/minimumAroundRadius).

## Options

<ParamField path="integer">
  Maximum radius in meters.
  Results beyond this distance are excluded.
</ParamField>

<ParamField path="all">
  Includes all records with a `_geoloc` attribute, regardless of distance from the center.
  Ranks results by proximity to the center.
  Faster than setting a large integer value.
</ParamField>
