Width: This is the distance from one leaf end to the other when the door hinge is open. Hinges having smaller leaf’s have comparatively smaller width than that of the bigger ones. The distance from outside of one end to outside of other hinge is hinge’s width. 

Length: The distance from bottom of leaf to the top is the length of the door hinge. Length (height) is simply how tall the hinge is from bottom to top.

Pitch: The pitch is the width of the knuckle. The distance across the knuckle is the pitch of the door hinge.

To measure the door hinges, you will need a flathead screwdriver, utility knife, measuring tape, one quarter and dime. Follow the steps to measure the door hinge:

First unscrew the middle one and then the others. There are commonly three screws at the side. It is important to make sure that you use the right tools.

Step 2: Take the width measurement of the door hinge

There are two different ways to size the hinge’s width. Firstly, lay the door hinge on flat surface and open it fully. Stretch the measuring tape or ruler from edge of one leaf to the other. This will also include the measurement of the pin and knuckle joint. Secondly, to measure the width, stretch the tape or ruler from the edge of one leaf to the center. Multiply it by two. This is the width of the door hinge.

Step 3:Measure the height of the door hinge

By keeping the tape parallel to the door hinge’s side from top to bottom, measure its height. Majority of the hinges are commonly of 3.5 inches, 4 inches, 4.5 inches, 5 inches or 6 inches.

Step 4: Measure its thickness

It is important to measure the thickness of the hinge. For this, the door must be recessed with the thickness of hinge. When the door is closed, measure its thickness. You can find hinge leaves of different thickness.

Step 5: Take the corner radius measurement of the door hinge

The corner radius is more curved; therefore, you need to measure it using a dime. Lay the hinge flat and place the dime and quarter on both the corners. This will give you the hinge’s corner radius. You can also determine its radius with the help of the ruler or tape measure. Stretch it from the top to the round area where it ends.

Step 6: Note the measurements

Take notes of all the measurements you take. Use these numbers to replace your existing door hinge.

  • If the door has1-3/8 inches thickness and width approximately 36 inches, buy hinges measuring 4 inches.
  • A hinge of 4-1/2 inches will be perfect for a 1-3/4 inches thick and 36 inches wide door.
  • For a door which is 1-3/4 inches thick, 36 – 48 inches wide, hinges of 5 inches should be installed.
  • If the door has 2 to 2-1/2 inches thickness and width more than 48 inches, buy heavy-duty hinges measuring 6 inches.
