Tools and Materials Needed
Accurate cabinet door measurement starts with the right tools. Always record cabinet door measurements to the nearest 1/16” for the best accuracy. Before you start measuring, grab these tools and materials:
- Tape measure (with 1/16” markings)
- Straightedge
- Calculator
- Painter’s tape (optional for overlay marking)
- Level
- Pencil
- Notepad or paper
You’ll use the tape measure, straightedge, and level to take accurate, consistent measurements across each cabinet opening. Painter’s tape is optional but can be used to mark the overlay to increase accuracy. Make sure to record measurements on your notepad as you go.
Identify Your Cabinet Door Type Before Measuring
The cabinet door type determines the overlay — the amount of face frame the cabinet door covers when closed. Identifying the type of cabinet you have will dictate how you measure the cabinet doors.
Full Overlay Cabinet Doors
Full overlay doors fully cover the cabinet when they’re closed. This is true for both frameless and face frame cabinets. This door style has minimal reveal, though it typically leaves about ⅛”–¼” of the face frame visible, depending on hinge selection.
Partial Overlay Cabinet Doors
Partial overlay doors cover part of the cabinet or face frame when they’re closed. The amount of reveal is variable and up to the home’s style and design goals. Accurate measurements and calculations are needed to ensure consistency across cabinets. The amount of overlay will correspond with the type of hinge needed. For instance, a ½” overlay will use a ½” concealed overlay hinge.
Inset Cabinet Doors
Inset doors sit inside the cabinet opening and are flush with the surrounding cabinet, requiring precise cabinetry measurements and tight tolerances. This style is popular in minimalist or modern homes because of the sleek profile it creates. The door needs room on each side to operate properly, so ¼” is subtracted from both the height and width measurements to account for clearance, which provides a ⅛” reveal between the cabinet door and cabinet opening.
Step-by-Step: How to Measure for Cabinet Doors
When measuring for new or replacement custom cabinet doors, follow these steps:
Step 1: Remove the Existing Door
Before removing the existing door, mark the overlay on the face frame with painter’s tape. Carefully remove the existing door from the cabinet. If you’re adjusting the overlay, you can wait until you remove the door and then mark the desired overlay.
Step 2: Measure the Cabinet Opening Width
Using your tape measure, measure the cabinet opening width to the nearest 1/16 inch. Take this measurement at multiple points (top, middle, and bottom) and use a level to ensure you’re measuring evenly on both sides. Record the measurement.
Step 3: Measure the Cabinet Opening Height
Using your tape measure, measure the cabinet opening height to the nearest 1/16” inch. As with the width, take this measurement at a few different points, using a level to ensure you’re measuring at the same points on the top and bottom. Record the measurement.
How to Measure for Overlay Cabinets
Overlay doors cover all or part of the cabinet or face frame. Measure the cabinets and calculate the door dimensions based on the following steps. (If you want guidance on hinges, check out our article on measuring cabinet hinges.)
Here’s how to measure for an overlay door:
Step 1: Determine the Overlay Amount
To determine the overlay amount, measure from the inside edge of the cabinet to the mark you made with your painter’s tape indicating where the edge of the door should rest on the face frame or cabinet box.
Step 2: Add the Overlay to the Door Dimensions
The final cabinet door dimensions will be the cabinet opening width and height plus the overlay on both sides. Using the following formulas, calculate the size of the door to the nearest 1/16”.
Width = opening + (overlay x 2)
Height = opening + (overlay x 2)
Step 3: Determine Hinge Type
The amount of overlay will determine the type of concealed hinges that you need. For instance, an overlay of 1-¼ inch will use a 1-¼” concealed overlay hinge. These instructions assume an equal overlay on both sides of your cabinet opening, which is typically the case except for double doors. Some custom cabinetry in face frame applications will have larger overlays on either side of the door.
How to Measure for Double Cabinet Doors
If you’re measuring for split doors or double doors with an overlay, the measurement will be slightly different. You’ll need to subtract a reveal (the gap between the doors) to achieve the proper overlay. This ensures the doors have enough clearance to open and close without hitting each other.
Here’s how to measure for double doors:
Step 1: Measure the Width and Height of the Cabinet Opening
As with standard doors, start by measuring the width and height of the cabinet opening.
Step 2: Measure the Overlay and Reveal
Use the existing doors to mark the overlay and reveal. If you’re working without the existing doors, mark these locations with painter’s tape and measure the distance from the inside cabinet edge to the overlay and reveal locations.The reveal between split doors is typically ⅛” and prevents the doors from hitting each other.
Step 3: Calculate Door Dimensions
Use the following formulas to determine the door size:
Width = (opening + (overlay x 2) - reveal) / 2
Height = opening + (overlay x 2)
How to Measure for Inset Cabinet Doors
Inset doors sit inside the cabinet opening and flush with the cabinet or face frame. To make sure the doors open and close easily, there is a small gap, or tolerance, between the door and the cabinet.
Step 1: Measure Cabinet Height and Width
Measure the cabinet height and width, making sure to measure at equal points on each side and at the top and bottom.
Step 2: Calculate the Door Size
To ensure enough clearance between the door and the face frame or cabinet box, there should be a ⅛” gap on all sides of the door. Use these formulas to guide your measurements:
Width = opening measured from edge to edge - ¼”
Height = opening measured from top to bottom - ¼”
Common Cabinet Door Measurement Mistakes
As you take measurements, avoid these common cabinet door sizing mistakes:
-
Not rounding to the nearest 1/16 inch for consistency.
-
Failing to double-check every measurement before submitting your order form
-
Not discussing your project with the cabinet manufacturer and checking their cabinet door specs and tolerances to make sure your measurements are clear
-
Measuring only the old doors and not the cabinet opening
-
Forgetting to account for door gaps
-
Not measuring at multiple points along the sides and the top and bottom
-
Choosing the incorrect hinge overlay
-
Not distinguishing between inset or overlay doors
Tips From Professional Cabinetmakers
Even though measuring cabinet doors is straightforward, installation precision depends on consistency across every opening. Professional cabinetmakers recommend taking a methodical approach to ensure accuracy and consistency across every opening. Consider these tips:
- Cabinet openings are rarely identical, so measure every cabinet opening individually to ensure accuracy.
- Always double-check measurements and calculations.
- Confirm hinge overlay before ordering.

Frequently Asked Questions
How do I measure if my cabinets are not level?
If your cabinets aren’t level, then choosing the right cabinet style can help mask any imperfections. Full overlay doors or inset doors will be more likely to bind if the opening isn’t consistent or cabinets are not level, but partial overlay doors are more forgiving. Use a level to identify high and low points and then record multiple measurements at different points and adjust your door measurements according to the best fit.
What clearance should I allow for hinges and handles?
Hinge overlay and clearance will depend on whether the door is an overlay or inset door and whether it’s mounted on a frameless or face frame cabinet. Doors on face frame cabinets typically have larger overlays than those on frameless cabinets to cover more of the face frame.
Typical hinge overlay clearance depends on your cabinet style and hinge type. For most overlay doors, allow at least 1/8" to 1/4" of clearance to prevent binding and ensure smooth operation. Handle pulls should also be placed far enough from adjacent doors or drawers — typically 2" to 2½" from the edge — to avoid collisions when opening.
Can I use a laser measure instead of a tape measure?
You can use a laser measure instead of a tape measure for accurate cabinet door measurements. A laser measure will help you get accurate and consistent readings. If you have both tools, you can check the measurements against each other to be as accurate as possible.
What if my measurements fall between standard sizes?
If your cabinet door measurements fall between standard sizes, you have a couple of options. First, you can adjust the overlay amount to get the door more in line with a standard size. Second, you can request fully custom-sized doors from Eagle Woodworking. We’ll work with you to determine the best sizing for our hand-finished custom cabinet doors.
What if my cabinet opening is not perfectly square?
If the cabinet opening isn’t perfectly square, still take measurements as accurately as possible. Measure at three points along the height and width and order based on the smallest number. Concealed hinges allow for adjustment, so when the doors are installed, you can adjust the doors from side-to-side and top to bottom to make them even.
How much reveal should I plan around cabinet doors?
It depends on the cabinet style and overlay type. For most cabinets, reveals (gaps) between doors and drawers are typically 1/8" to 1/4" to prevent rubbing, with tighter gaps—around 1/16"—common in frameless or inset cabinets. Partial and full overlay cabinets differ in how much of the frame is covered, but the reveal between doors should remain consistent regardless of overlay type.
Should I measure the cabinet door or the cabinet opening?
Base your measurements off of the cabinet opening, making sure to measure each opening individually. After you calculate the correct door dimensions using the overlay or inset formulas, then you can check these measurements against the existing cabinet doors.
What is the standard cabinet door overlay?
Standard overlays range from 1/4” to 1-1/4”. The actual overlay depends on the cabinet type and the desired look. A full overlay cabinet door typically has a ⅝” overlay for a frameless cabinet and a 1-¼” overlay for a face frame cabinet. A partial overlay cabinet door typically has a ¼” overlay for a frameless cabinet and a ½” overlay for a face frame cabinet.
What gap should be between cabinet doors?
The gap or reveal between cabinet doors should be ⅛” to ¼”. This allows room for the doors to operate without rubbing against each other.
Can I change overlay size when replacing doors?
Yes, you can change the overlay size when replacing doors. If this is the case, then you shouldn’t use the existing doors to determine the measurements. Instead, determine the amount of overlay you want and use it in the overlay measurement formula. Before making your final decision, make sure the cabinet style and hinge options will support the new overlay.
