# area

The area covered by the body.

## Declaration

```swift
var area: CGFloat { get }
```

## Mentioned in

Configuring a Physics Body

## Discussion

Discussion This property is used in conjunction with the density property to calculate the body’s mass. The value returned for the area is measured in meters: if you need to convert it into points — as used by SpriteKit — multiply the values by 150². The following listing shows how to calculate the area of a box which is ten points square. let bodySize = CGSize(width: 10, height: 10) let physicsBody = SKPhysicsBody(rectangleOf: bodySize) let areaInPoints = physicsBody.area * pow(150, 2) // areaInPoints = 100
