Answer:
In Photoshop, on a new document at 900 pixels wide, use this cover crop: 1 5:4
Then paste in text like so, making sure you change the type to match the text in the cover crop.
Cover crop is for you to tell Photoshop the height and width of the photo.
In this instance it’s 5:4, which means 1/3 the width of the screen (900 pixels) and 4 units tall.
