Assessing the hinges on your cabinets is crucial for ensuring their proper functionality and alignment. Whether you’re planning a kitchen remodel or simply replacing worn-out hinges, accurate measurements are essential for selecting the correct replacements. Fortunately, measuring cabinet hinges is a relatively straightforward process that can be accomplished with a few simple steps using basic tools like a measuring tape or ruler.
Before you begin, gather the necessary tools and identify the type of hinges used on your cabinets. Common hinge types include overlay, inset, and wrap-around hinges, each with specific measurements that need to be taken. Once you have identified the hinge type, you can start measuring its dimensions. The most important measurements to note are the hinge’s height, width, and overlay (if applicable). The hinge height is the distance from the top to the bottom of the hinge, and the width is the distance from one side to the other. The overlay measurement is the amount by which the door overlaps the cabinet frame when closed.
To measure the hinge height, place the measuring tape or ruler against the top of the hinge and extend it to the bottom. Record this measurement in inches or millimeters. For the hinge width, place the measuring tape or ruler against one side of the hinge and extend it to the other side. Again, record this measurement in inches or millimeters. If the hinge is an overlay hinge, you will also need to measure the overlay. To do this, close the cabinet door and measure the distance between the edge of the door and the edge of the cabinet frame. Record this measurement in inches or millimeters. With these measurements, you will be able to purchase the correct replacement hinges for your cabinets, ensuring a seamless fit and optimal functionality.
Determining the Hinge Type
Before proceeding with measurements, it is crucial to identify the specific type of cabinet hinge you are dealing with. Key characteristics to consider are the hinge’s overall design, its point of attachment, and its function. Here’s a detailed explanation of the most common types of cabinet hinges:
Overlay Hinges
Overlay hinges, also known as face frame hinges, are designed to be attached to a face frame that surrounds the cabinet opening. They typically feature two leafs that overlap the cabinet door and the face frame, providing a seamless and concealed appearance when the door is closed.
Overlay hinges come in various sizes and styles, with the most common types being self-closing and spring-loaded. Self-closing hinges have a built-in mechanism that provides a gentle pull to close the door, while spring-loaded hinges rely on tension to keep the door shut.
Inset Hinges
Inset hinges, also known as European hinges, are designed to be concealed within the cabinet opening. They have two arms that extend into the cabinet and attach directly to the inside of the door. Inset hinges provide a clean and minimalist look, making them a popular choice for modern and contemporary kitchen designs.
Inset hinges typically have a self-closing mechanism and are adjustable, allowing for precise alignment of the door. They are also available in different sizes and finishes to match the cabinetry.
Overlay versus Inset Hinges: A Comparison
| Feature | Overlay Hinges | Inset Hinges |
|---|---|---|
| Attachment Point | Face frame | Inside cabinet opening |
| Appearance | Overlaps cabinet door and face frame | Concealed within cabinet opening |
| Common Types | Self-closing and spring-loaded | Self-closing and adjustable |
| Style | Traditional and classic | Modern and contemporary |
Measuring Hinge Size
Identifying the Hinge Type
Before measuring the hinge, determine its type:
- Butt hinge: The most common type, with two leaves that fold together.
- Concealed hinge: Hides behind the cabinet door when closed.
- European hinge: A frameless hinge, typically used in modern cabinetry.
Determining Hinge Measurements
Step 1: Measure the Hole Spacing
Locate the mounting holes on the cabinet door and frame. Measure the distance between the centers of the holes. This is the "hole spacing."
Step 2: Measure the Hinge Height
From the bottom of the door to the center of the topmost hole on the door, measure this length. It is the "hinge leaf height."
Step 3: Measure the Hinge Width
The hinge width is the distance between the edges of the hinge leaves. This measurement is not crucial for installation, but it can be useful for determining the appropriate size of the mounting plate.
Step 4: Measure the Hinge Overlay
The hinge overlay determines how much the door overlaps the cabinet frame when closed. Measure the distance from the edge of the door to the center of the hinge pin. This is the "hinge overlay."
Hinge Size Chart
Common hinge sizes based on hole spacing:
| Hole Spacing | Hinge Height | Hinge Width |
|---|---|---|
| 1/2" | 2-1/2" | 1" |
| 5/8" | 2-5/8" | 1-1/4" |
| 3/4" | 2-7/8" | 1-1/2" |
| 1" | 3-1/8" | 1-3/4" |
Determining Hinge Placement
Cabinet hinges are essential components of any cabinet, as they determine how the doors open and close. To ensure a proper fit, it is crucial to measure the hinges accurately. Follow these steps to measure cabinet hinges:
1. Determine the Type of Hinge
First, identify the type of hinge you will be using. There are various types of hinges available, such as concealed hinges, butt hinges, and piano hinges. The type of hinge will determine the measurements you need to take.
2. Measure the Door Thickness
The thickness of the cabinet door will determine the size of the hinge cup. Measure the thickness of the door at the point where the hinge will be mounted. This measurement will be used to determine the diameter of the hinge cup.
3. Determine the Hinge Offset
The hinge offset is the distance between the center of the hinge cup and the edge of the door. This measurement is critical, as it affects the alignment of the door when it is opened and closed. Here’s a detailed breakdown of the hinge offset measurement:
- Set the Door Inset: The distance between the door’s edge and the cabinet’s edge is known as the door inset. Determine the desired door inset, which typically ranges from 1/8″ to 1/2″.
- Calculate the Hinge Overlay: The amount by which the door overlaps the cabinet frame is referred to as the hinge overlay. Determine the required overlay, usually between 1/4″ to 1/2″.
- Subtract the Overlay: Subtract the hinge overlay from the door inset to obtain the hinge offset. This value indicates the distance between the hinge cup’s center and the door’s edge.
The following table summarizes the relationship between the door inset, hinge overlay, and hinge offset:
| Door Inset | Hinge Overlay | Hinge Offset | |||||||||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1/2″ | 1/4″ | 3/8″ | |||||||||||||||||||||||||||||||||
| 1/4″ | 1/8″ | 3/16″
Using a Template for AccuracyUsing a template is a foolproof method to ensure accurate measurements for your cabinet hinges. Templates are typically available from the hinge manufacturer or online. To use a template: 1. Center the TemplateAlign the template with the center of the cabinet door and secure it using masking tape or clamps. Make sure the template is level and parallel to the door’s edge. 2. Mark the Hinge LocationsTransfer the hinge locations from the template to the cabinet door using a pencil or awl. Use a sharp tool to create clear and precise marks. 3. Use a Drill GuideFor added accuracy, use a drill guide to drill pilot holes for the screws. Align the guide with the marking on the template and drill through the door. 4. Countersink the HolesCountersinking the screw holes prevents the screw heads from protruding from the door’s surface. Use a countersink bit that matches the diameter of the screw heads. Drill a small countersink hole in each pilot hole, ensuring the screw heads will sit flush with the door. Here’s a quick summary of the steps for countersinking holes:
Measuring for Overlays or Inset DoorsOverlays: For overlay doors, measure from the outside edge of the face frame to the center of the hinge hole. This measurement will determine the distance from the front of the cabinet to the center of the hinge cup once mounted. Insets: For inset doors, measure from the inside edge of the face frame to the center of the hinge hole. This measurement will determine the distance from the back of the door to the center of the hinge cup once mounted. To determine the correct overlay or inset distance, refer to the manufacturer’s specifications for the specific hinges you are using. Measuring the Hinge CupThe hinge cup is the part of the hinge that attaches to the cabinet face frame. To measure the hinge cup, you need to know the following:
Measuring the Hinge ArmThe hinge arm is the part of the hinge that attaches to the door. To measure the hinge arm, you need to know the following:
Determining the Correct Hinge SizeOnce you have measured the cabinet face frame, door, and hinge cup and arm, you can determine the correct hinge size. Refer to the manufacturer’s specifications to find a hinge that matches your measurements. Tips for Measuring Hinge Locations
Measuring for Corner CabinetsMeasuring for corner cabinets requires a slightly different approach due to their unique shape and the need to accommodate the door’s swing radius. Here are the additional steps to consider: 1. Determine the Door Type:Identify the type of door you will be using, whether it’s an inset, overlay, or flush-mounted door. 2. Measure the Door Width:Measure the width of the door, which will determine the size of the hinges you need. 3. Calculate the Overlay:For overlay doors, measure the amount of overlap between the door and the cabinet frame. 4. Calculate the Inset:For inset doors, measure the depth of the inset, which is the distance between the edge of the door and the back of the cabinet frame. 5. Determine Hinge Offset:Measure the distance from the edge of the door to the center of the hinge mounting hole. This is called the hinge offset. 6. Calculate the Hinge Cup Depth:To determine the depth of the hinge cup, you need to consider the following factors:
The formula for calculating the hinge cup depth is:
By following these additional steps, you can accurately measure for corner cabinets and ensure that your hinges are properly installed for optimal door operation. Measuring for Blind Corner CabinetsBlind corner cabinets can be tricky to measure for hinges, but it is important to get it right in order to ensure that the doors open and close smoothly. Here are the steps on how to measure for blind corner cabinets: 1. Determine the Type of HingeThere are two types of hinges that can be used for blind corner cabinets: 170-degree hinges and 180-degree hinges. 170-degree hinges are the most common type and allow the door to open to a 170-degree angle. 180-degree hinges allow the door to open to a full 180 degrees. 2. Measure the Door HeightMeasure the height of the door from the top to the bottom. This measurement will be used to determine the length of the hinge. 3. Measure the Door WidthMeasure the width of the door from the left to the right. This measurement will be used to determine the width of the hinge. 4. Determine the OverlayThe overlay is the amount of the door that overlaps the cabinet frame. The overlay can be full overlay, half overlay, or inset. 5. Calculate the Hinge LengthThe hinge length is determined by the door height and the overlay. For a full overlay, the hinge length will be equal to the door height. For a half overlay, the hinge length will be half of the door height. For an inset, the hinge length will be less than half of the door height. 6. Calculate the Hinge WidthThe hinge width is determined by the door width and the overlay. For a full overlay, the hinge width will be equal to the door width. For a half overlay, the hinge width will be half of the door width. For an inset, the hinge width will be less than half of the door width. 7. Measure the Hinge Bore HoleThe hinge bore hole is the hole that is drilled into the door for the hinge. The bore hole size is typically 35mm in diameter and it is important to center the hole properly on the back of the door. To do this, measure and mark the center of the door and then drill the hole using the correct bit size.
Using a Hinge Tool for PrecisionFor maximum accuracy when measuring cabinet hinges, consider investing in a dedicated hinge tool. These specialized tools typically feature:
Step-by-Step Guide:1. Identify the Hinge Overlay: Use the ruler on the hinge tool to determine the desired overlay measurement. This determines how much the door will overlap the cabinet frame. Calculating the Number of Hinges NeededThe number of hinges required for a cabinet depends on several factors, including the size and weight of the door, the type of hinges used, and the desired level of support. Here are some guidelines to help you determine the appropriate number of hinges: 9. Hinges for Heavy Doors or Large KitchensFor heavy doors or large kitchens with multiple cabinets, a heavier-duty hinge is recommended. These hinges may require additional screws or mounting hardware to ensure proper support. Consider using three or four hinges per door to distribute the weight evenly. For doors wider than 36 inches, an additional hinge may be necessary to prevent sagging or warping. To determine the specific number of hinges needed for a given door, consult the manufacturer’s specifications or consider the following table:
Remember that these are general guidelines and the actual number of hinges may vary depending on the specific door and hinge type used. How to Measure Cabinet Hinges1.
