Quote from How to Install a Screen Door :
Check it, if you screen doors can fit in the needed gap. If not, then you may need to do a trimming. Mark the length of the gap on your screen doors and trim 1/8 inch from both sides and ½ inch from the height. Be careful not to trim your screen door to more than 3/8 inch from both sides and 1 inch from the length, otherwise you will have an uneven result.
