It's just a 4:5 ratio vertical frame.
You can use guides within Photoshop to create one, or even use a selection

choose fixed ratio, type 4 in width and 5 in height, create your selection and fill the canvas with it, center it to the square using the snapping features, and you're done!

Alternatively, yopu can find templates overlays here:
