# majorRadiusTolerance

The tolerance (in points) of the touch’s radius.

```
var majorRadiusTolerance: CGFloat { get }
```

## Discussion

This value determines the accuracy of the value in the [`majorRadius`](/documentation/UIKit/UITouch/majorRadius) property. Add this value to the radius to get the maximum touch radius. Subtract the value to get the minimum touch radius.
