# ARPlaneClassification

Possible characterizations of real-world surfaces represented by plane anchors.

```
enum ARPlaneClassification : NSInteger;
```

## Overview

You get values of this type from a plane anchor’s [`classification`](/documentation/ARKit/ARPlaneAnchor/classification-2hi2p) property, identifying the likely type of real-world surface for a detected plane anchor.

## Topics

### Plane Classifications

[`ARPlaneClassificationNone`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationNone)

No classification is available for the plane anchor.

[`ARPlaneClassificationWall`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationWall)

The plane anchor represents a real-world wall or similar large vertical surface.

[`ARPlaneClassificationFloor`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationFloor)

The plane anchor represents a real-world floor, ground plane, or similar large horizontal surface.

[`ARPlaneClassificationCeiling`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationCeiling)

The plane anchor represents a real-world ceiling or similar overhead horizontal surface.

[`ARPlaneClassificationTable`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationTable)

The plane anchor represents a real-world table, desk, bar, or similar flat surface.

[`ARPlaneClassificationSeat`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationSeat)

The plane anchor represents a real-world chair, stool, bench or similar flat surface.

[`ARPlaneClassificationDoor`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationDoor)

The plane anchor represents a real-world door, or similar archway.

[`ARPlaneClassificationWindow`](/documentation/ARKit/ARPlaneClassification/ARPlaneClassificationWindow)

The plane anchor fits the description of a real-world window.
