What is my Door Handing?
The easiest way to determine your door handing:
Step into the open doorway with your back to the hinges. You will be standing sideways
in the opening, looking at the jamb side where the door latches. If the door and hinges
are on the left side, it is a left-hand door. If the door and hinges are on the right side, it is
a right-hand door. Simple.
How to Measure Your Rough Opening

If you are replacing an existing door, remove the casing or trim from one side of the
door open.
