Left or Right Swing Door

In or Outswing - Right or Left Hand

Exterior doors: In or out refers to inside or outside your house. Inswing means that the door opens to the inside. Outswing means the door opens to the outside. In-and out requires a reference point: from the inside. If you enter from the outside, you are in-swinging a door - the in refers to the house inside or outside - not the direction you are pushing. From the outside - you are pushing away from you, not pulling towards you.

For interior rooms: consider the room being secured being the inside. Same logic applies as above. If you pull your door to leave the bedroom - you have an inswing bedroom door.

Inswing is desirable - so you don't clothesline people in the hallway. Inswing is desirable for exterior doors for safety- if it's a break-in - you can push the door shut with your body. If the door swung out, if you decide that you have an intruder, it would be harder to shut the door in their face.

Ambiguous case: for a door between two rooms - it can be ambiguous which direction is inswing and which is outswing.

The ambiguous case makes you ask questions: 1. Is the door identical on each side? Then hinges can likely be remounted so you obtain inswing or outswing. 2. For handedness - is the door hinge on right or left side? If the door can function equally upside down, then the door could be right or left-handed.

This gets into how left and right hand is defined.

When you go up to a door, are you using your right or left hand to open it? That determines the handing. But that is not a transparent definition. If you go up to a door, you can open it with your right hand or with your left hand. For a person without a right hand, the left hand would be more convenient. So the right- left- distinction based on which hand you use is a poor one.

A door that has ambiguous in- or outswing cannot be called in-swing or outswing. It can only be right or left handed. The definitive way to define handedness is to open the door, put your back against the hinge. If the door handle is closer to your right hand, it is called right hand, and vice versa:

Both in- and out-swing-ness (even in ambiguous case) determines the right or left handedness. Handedness is thus not determined by:

• Whether hinge is on right or left side. When you look at a door from the outside - for example - its handedness will be different if it is inswing or outswing - regardless of the hinge being on the left side.
• It is not dependent on which hand you use to open it 'in the most convenient manner' - convenience may vary for different people - some may use right, others may use their left hand.
• It is not the direction that the door opens. This direction changes whether you are looking from the inside or outside.
• One could say 'when standing inside the house or room' - because this term is ambiguous.

Further Complications

The hardware such as a lever could also be left or right handed, while it may not matter for others. [1]

In and Out vs Reverse

Some call 'outswing' - 'reverse' [2]. This is not consisent with the 'back to hinge' method of the youtube vid.

Door Handing

'Right hand' or 'left hand' refers to the hand that you use to open the door. The convention is that the door knob is on the right side for a right hand door, and on the left side for a left hand door.
