If it opens when I reach for it it is right handed. If I smash my face, it was left handed. 

For me - with the door opening away from you rather than opening towards you - if the door swings to the left - it's a left handed door. If the door swings to the right it's a right handed door. Which I believe matches your description.

Gee- I thought this was going to be like going to watch the submarine races

Yes, that is the answer

Thank you.

Barbara Todaro - and I love questions like this... thanks.

Eezy peezy

I have no clue, unless it's the fridge door.

LOL...keep them coming. 

I love open book quizes too! Thanks for the answer!

Does it depend upon whether the door opens in or out?

You nailed that one

Thanks for another open book quiz, Barbara.

Thanks for your knowledge on the subject

Where was that trick as I was thrown into the fire of new construction so many years ago Barbara Todaro 

Which ever hand you use to open it, would've been my guess.

If I open it with my left hand ... it is a left handed door. The opposite is true for a right handed door. 

My husband sold doors for years and said put your butt against the butt hinge and reach for the door handle with the hand closest to it. That tells you the hand.

Well now I know.

Thomas J. Nelson, Realtor, CRS nailed this one!

What if it's a French Door?

Where the hinge is and where the knob is.

by the hand that reaches out to touch it?

Your answer is confusing but correct (as I had to back up to my closest door) lol.

I like your "read the answer before you have to struggle with it on your own" style!

I'm thinking about the doors in my house and I have both.

I like Michael Setunsky answer

On the refrigerator door we came up with a reversible design. It saved the logistics of stocking leftie and rightie. 

My thought was the same as Dan Pittsenbarger's as far as determining this. Different appraoch, same answer!

Did not know that factoid.

This site has a pretty good explanation for both interior and exterior doors and also includes some things to watch for, e.g. when ordering locksets and the lockset site has a totally different description for "handing" a door.

But what I know personally - it always ends up being the opposite "hand" from what I think it is. :0)

It always goes back to location, right?  Or position.  In the case of doors, I believe it has to do with location/position of the hinges.  

Barbara Todaro Something to do with the hinges.
