Look at the door; it should be pretty easy to tell what side of the door is the outside, and what side is the inside. Outside of a bedroom door you would be standing in the hallway, if you are in the bedroom you are looking at the inside of the door. If you are standing on your front porch looking at the front door, then your are looking at the outside of the door. Know this before installing door levers and handles.
Door handing is always done from the OUTSIDE of the door. Whatever side the hinges are on, when viewed from the outside is the same as the door hand. If the hinges are on the right, it’s a right hand door. If the hinges are on the left, it’s a left hand door. It does not matter if the door pulls towards you or opens away from you. If you don’t know your left from right, ask someone. You only need to determine what side the hinges are on from the OUTSIDE. Forget the “reverse bevel” term.
Now you are ready to install your doors handles or door levers.
Note: There is one exception to this rule…single dummies. When handing a single dummy you stand on the side of the door that you are mounting the dummy on, not the exterior side.
