Hinges and Hardware 101 - Open Width Vs. Leaf Width

One of the dimensions on your hinge is the Open Width, and sometimes it's confused with the term Leaf Width.  Open width is the dimension across both leaves, measured perpendicular to the pin.  This would be the 2" dimension in this picture.   The Leaf Width is measured from the center of the pin to the edge of the leaf. This is the 1" dimension in this picture. In most cases the leaf widths would be half the total open width except in unequal leaf situations where one leaf is wider than the other.  Check out more information on hinge width and other hinge anatomy details here.
