# size

The size of the “slice” of noise samples contained in the noise map relative to the unit coordinate space of the noise object it was created from.

## Declaration

```swift
var size: vector_double2 { get }
```

## Discussion

Discussion If you later generate a texture image from the noise map with the SKTexture class, this size is also the pixel dimensions of the texture to generate. This property is read-only; you define the size of a noise map when creating it with the interpolatedValue(at:) initializer.
