When you work with Kwik, Kwik needs 1920x1280 .psd (320x480 with @4x system), but the background layer should be 2280 x 1440 or 2776 x 1440(iPhone X), you may want to make the entire background layer visible. The action Show 2280 x 1440 enlarges the Canvas size with the guide layers.

To make a background enlarging 2280x1440. Image > Canva Size

Draw the framed area. If you like to set guidlines
- (2280-1920)/2 = 180, 2100
- (1440-1280)/2 = 80, 1360

Set it back to 1920x1280

Now you can work with Kwik

iPhone X is 360x694 @4x = 1440x2776
The safe area guidlines,
- (2776-1920)/2 = 428, 2348
- (1440-1280)/2 = 80, 1360
