Left hand vs right hand interior doors?

Left-hand and right-hand interior doors refer to the direction in which the door swings when facing it from the outside. A left-hand door swings open towards the left, while a right-hand door swings open to the right. This distinction is important for proper installation and functionality, particularly in terms of space usage and accessibility. To determine the hand of a door, stand outside the door facing it; if the hinges are on the left, it's a left-hand door, and if they're on the right, it's a right-hand door.
