What defines the orientation and swinging direction of a door?

The orientation and swinging direction of a door are determined by the hand of the door. The "hand" refers to whether the door is a right-hand or left-hand door based on its hinge placement and how it swings when viewed from the outside. A right-hand door swings outward to the right, while a left-hand door swings outward to the left. Understanding the hand of the door is crucial for installation, ensuring that it opens in the desired direction for functionality and convenience. Other factors like door size, material, and color do not affect how the door operates or its orientation; they pertain to dimensions, aesthetics, and structural properties, but not to its swinging mechanism.
