The basic standard residential door hinge is what as known as a plain bearing hinge. They
are simply 2 halves of metal with a pin that joins the halves. They are separated by the different
types of metals (steel, stainless steel or brass) they are made from, the hinge size,
and the style of corner the hinge has.
Let start with the Hinge Corners:
There are 3 styles of hinge corners - Square, 1/4 Inch Radius (round corners) and 5/8 Inch Radius (round corners).
The square corner is a simple 90 degree corner.
To determine if you have a 1/4" or 5/8" radius hinge, measure from the beginning
of the curve to where the corner of the hinge would be if it were a square corner.
Tip to measure hinge Corner Radius:
A 1/4" radius matches up to the radius of a US dime and a 5/8" radius matches up to a US quarter.
As you can see from the photo below, it is not exact, but it sure is close.
