I’m working on building a storm door for my front entrance, which has a round top door in it. One thing I did not account for: because the door is recessed, when you open the storm door, the brickwork on the hinge side ends up hitting the top of the door. With the hinges I bought (which fit the mortises that were already in the casing from a previous screen or storm door, which I don’t have), the door opens less than 90 degrees, probably about 80 I’d say. I’m thinking that if I went with a wider hinge it would push the door further out when opened, giving some more clearance on that top edge. I’m not really sure how to figure out how wide of a hinge I need though.
