# sensorAspect

The ratio of width to height for the camera’s simulated imaging surface.

## Declaration

```swift
var sensorAspect: Float { get set }
```

## Discussion

Discussion To determine the width of the imaging surface, use this property and the sensorVerticalAperture property. For example, with the default vertical aperture of 24mm and default aspect ratio of 1.5 (or 3:2), the horizontal aperture is 36mm.
