Many people think that French doors are any set of interior or exterior entryways that utilize two doors with hardware facing inward, toward one another. But there are many, many different kinds of double doors, from those we commonly see in residential areas to those we see in public spaces, including hospitals, grocers, arenas, and so on — these ultra-durable double doors are a far cry from the delicate elegance that French doors are. So, in the most authentic sense, what are French doors?

In fact, this has nothing to do with why a French door is called "French" in the first place. French doors, it's true, are nearly always double doors, but the reverse is untrue. In order for a door to be genuinely French, it must have glass panes from top to bottom — these may also be referred to as lights or lites by those within the industry. Rather than thinking of them as double doors, think of them as one, giant door split in the middle — much like a Dutch door is cut in half from top to bottom, a French door, is one that's been cut in half from one side to the other.
