Step 1: Selecting the Correct Hinge Type

Before you can measure your cabinet hinge, you need to determine the correct hinge type for your specific cabinet door. There are various types of hinges available, including overlay hinges, inset hinges, and half-overlay hinges. Each type has different installation requirements and measurements.

If you’re unsure about the hinge type you need, examine your cabinet door to determine how it overlaps the cabinet frame. Here are the three common hinge types:

1. Overlay hinges: These hinges are visible from the outside when the cabinet door is closed. Measure the overlay by determining the distance between the edge of the door and the edge of the cabinet frame. Common overlay measurements include 1/2 inch, 3/4 inch, or full overlay (where the door completely covers the cabinet frame).
2. Inset hinges: These hinges are concealed and allow the cabinet door to fit flush with the cabinet frame. Measure the inset hinge by determining the distance the door will be set back from the edge of the cabinet frame. Inset hinges typically have a 3/8 inch inset measurement.
3. Half-overlay hinges: These hinges are a combination of overlay and inset hinges. One side of the door will have an overlay while the other side fits flush with the cabinet frame. Measure the overlay and inset portions accordingly.

Once you have determined the correct hinge type, you can move on to measuring the specific dimensions of the cabinet hinge components. This will ensure a proper fit and smooth operation of your cabinet doors.

Step 2: Measuring the Door Overlay

Measuring the door overlay is an essential step in determining the correct size of your cabinet hinge. The overlay refers to the distance the cabinet door overlaps the cabinet frame when it is closed.

To measure the door overlay, follow these steps:

1. Carefully close the cabinet door, ensuring it is aligned with the frame.
2. On the hinge side of the door, use your tape measure to measure the distance between the outer edge of the door and the outer edge of the cabinet frame.
3. Note down the measurement in inches or millimeters. This measurement will specify the overlay size required for your cabinet hinge.

Remember to measure both sides of the door if you have a double-door cabinet. It’s essential to be as accurate as possible when measuring the overlay to ensure the correct hinge fit.

Common overlay sizes include 1/2 inch, 3/4 inch, or full overlay, where the door completely overlaps the cabinet frame. By correctly measuring the door overlay, you’ll be able to select the appropriate size and type of hinge for your cabinet doors.

Step 3: Measuring the Cup Size

The cup size of a cabinet hinge refers to the diameter of the circular recess that is drilled into the door to accommodate the hinge mechanism. It is crucial to measure the cup size accurately to ensure a proper fit.

To measure the cup size of your cabinet hinge, follow these steps:

1. Open the cabinet door fully, exposing the hinge assembly.
2. Locate the circular recess or “cup” on the back of the door where the hinge sits.
3. Using a tape measure or digital caliper, measure the diameter of the cup. Make sure to measure from one side of the cup to the opposite side, passing through the center.
4. Note down the cup size measurement in inches or millimeters.

Common cup sizes for cabinet hinges are typically 35mm, 26mm, or 10mm. By accurately measuring the cup size, you can select a hinge that fits securely within the drilled recess, allowing the door to open and close smoothly.

Remember, if you are replacing existing hinges, it is essential to match the cup size of the new hinges to the old ones to ensure compatibility and a proper fit.

Use a ruler or tape measure to measure the length and width of the hinge, as well as the distance between the screw holes. This will help you find the right replacement hinge for your cabinet.

Step 4: Determining the Hinge Opening Angle

The hinge opening angle refers to the angle at which the cabinet door swings open when the hinge is installed. It is important to determine the hinge opening angle to ensure that the door can open and close smoothly without any obstructions.

To determine the hinge opening angle, follow these steps:

1. Close the cabinet door completely.
2. Carefully examine the hinge to determine its design and functionality.
3. Identify whether it is a standard 90-degree hinge or a specialty hinge with a different opening angle.
4. If it is a standard 90-degree hinge, the opening angle is already known.
5. If it is a specialty hinge with a different opening angle, carefully measure the angle using a protractor or a specialized angle measuring tool.
6. Note down the hinge opening angle in degrees.

Common hinge opening angles include 90 degrees for most standard hinges, as well as 110 degrees or 180 degrees for specialty hinges. By determining the correct hinge opening angle, you can select the appropriate hinge type that allows the door to open and close smoothly within the space available.

Remember, it is crucial to choose a hinge with an opening angle that suits the dimensions and functionalities of your cabinet and door.

Step 5: Measuring the Depth of the Boring

The depth of the boring refers to the depth of the hole that needs to be drilled into the cabinet door or the cabinet frame to accommodate the hinge. It is important to measure the depth accurately to ensure a secure and proper installation of the hinge.

To measure the depth of the boring, follow these steps:

1. Examine the hinge and identify the part that needs to be inserted into the door or the frame.
2. Take your tape measure and measure the length of the hinge part that should be inside the door or the frame.
3. Make sure to note down the measurement in inches or millimeters.

Common boring depths for cabinet hinges range from 1/2 inch to 3/4 inch. By accurately measuring the depth of the boring, you can ensure that the hinge is properly secured and provides the necessary stability for the cabinet door.

Remember to take precise measurements and choose a hinge that matches the depth requirements of your cabinet door or frame.

Step 6: Measuring the Backplate Size (If Applicable)

Some cabinet hinges come with a backplate, which is a flat metal piece that attaches to the cabinet side or the door. The backplate provides additional support and stability to the hinge. If your hinge has a backplate, it is important to measure its size accurately for proper installation.

To measure the backplate size, follow these steps:

1. Locate the backplate attached to the hinge.
2. Measure the width and height of the backplate using a tape measure.
3. Note down the measurements in inches or millimeters.

Some backplates may have specific mounting hole specifications as well. In this case, measure the distance between the mounting holes to ensure compatibility with your cabinet or door.

By accurately measuring the backplate size, you can select a hinge that matches the dimensions of your cabinet or door and ensures a sturdy and secure installation.

Keep in mind that not all hinges have a backplate, so if your hinge does not have one, you can proceed to the next step.

Step 7: Checking for Any Additional Features or Specifications

Before finalizing your cabinet hinge selection, it’s important to check for any additional features or specifications that may be required for your specific cabinet and door.

Here are a few aspects to consider:
