How To Measure Your Cabinet Door

There are some tips here for measuring your cabinet doors. If you have never done this before, you can learn the basic process. You must be sure that your measurements are done properly so that you can install each cabinet door with confidence. 

A Few Measuring Principles

  • Measure twice to ensure you have gotten it right the first time
  • Write down your measurements as soon as they are taken
  • Measure Openings for each door up to the 1/16th of an inch
  • Your measurement should be width by height. Some people grew up doing the opposite, and you do not want to receive the wrong doors because you wrote down your measurements improperly.
  • Remove your old cabinet doors before measuring

A Note About Your Measurements

These tips are best used when you are buying the popular hidden hinge cabinet door. If you are using a different type of hinge, you may need to change the way your measurements are taken.

STEP 1: Measure The Cabinets

Start by measuring the width and height of the inner frame of the cabinet.  We call this the cabinet opening measurements. Again, remove the cabinet door so that you can easily move the tape measure to the edge of the opening.

STEP 2: Determine the Door Size

You can use the formulas listed below to account for everything from door overlays to split doors. Make sure you know what kind of doors you are measuring for. When placing the order, you will use the measurement after adding the door overlay and type.

Calculating the Door Overlay

The door overlays on both sides to completely cover the opening. For example, you add a full inch to your measurements if you want a half-inch of overlay on each side. The formula looks like this:

width + overlay = Width of Door Ordered
height + overlay = Height of Door Ordered

For cabinet opening of 17-inch width x 32-inch height, add 1 inch to both measurements so it now reads 18-inch width x 33-inch height.

Please note:
We have used a half-inch overlay. You could choose any overlay length that you want. Depending on what you want, you may change the overlay from one cabinet to another.

We have provided examples here to help you understand. Please check your measurements twice to ensure they are correct. Our measurements should not be used for your cabinets.

Hinges need to match the overlay of your cabinet door.  Ensure the hinge you want to use works with your overlay.  See this article for help finding hinges to match your desired overlay.

Calculating for a Split Door Measurement

When you are using split doors, you need to account for the gap between the doors, the overlay of the doors, and the size of the doors. You have two doors per cabinet. Get a split door cabinet set when the cabinet opening is more than 22 inches. For a 1/2-inch overlay, you will add 1-inch to the width and height.  Next, you will divide the full width by 2 and subtract 1/16-inch to allow a 1/8-inch gap between the two doors.

The Formula for Split Door (1/2” overlay)
(width + 1) / 2 – 1/16 = Each Door Width
height + 1 = Each Door Height

The example
For cabinet opening measurement of 33-inch width x 26-inch height

Calculate the width:

  1. Double the Overlay (1/2 inch) = 1-inch
  2. Add Overlay to Cabinet Opening Width: 33-inch + 1-inch (doubled-overlay) = 34-inch width
  3. Split the number by 2 for each door: 34-inch divided by 2 = 17-inch
  4. Now subtract 1/16-inch so the doors don't hit (gap): 17-inch subtracted by 1/16-inch = 16-15/16-inch
  5. Final measurements for each door (order two) = 16-15/16 inch width x 27-inch height (height includes the 1 inch for overlay)

Please Note:  You should not use these measurements. We are merely providing examples to help you do the job right. If you are not using a hidden hinge, you may need to use a different measurement system.

Calculating for Inset Doors

An inset door fits inside the door opening instead of over it. When you take these measurements, you can use the tips above. However, you must remove an eighth of an inch from the width and height to allow for a gap between the door and the frame.

The Formula
Inset doors = "cabinet opening width" subtracting 1/4-inch x "cabinet opening height" subtracting 1/4-inch

The Example
If the cabinet opening is 18-inch width x 28-inch height
Inset calculation for width: 18-inch width - 1/4 inch = 17-3/4 inch
Inset calculation for height: 28-inch height - 1/4 inch = 27-3/4 inch

Calculating for Split Inset Cabinet Doors

You can do the same thing you saw above, but you need to divide the width by two because there will be two doors. You must also subtract 1/16 of an inch to account for the gap between the doors.

The Formula
Inset doors width = "cabinet opening width" subtracting 1/4-inch divide by 2 and then subtract 1/16-inch
Inset doors height = "cabinet opening height" subtracting 1/4-inch

The example
For cabinet opening measurement of 33-inch width x 26-inch height

Calculate the width:

  1. Subtract 1/4-inch: 33-inch minus 1/4-inch = 32-3/4 inch width
  2. Divide by 2 for the doors: 32-3/4 inch divided by 2 = 16-3/8 inch width
  3. Now subtract 1/16-inch so the doors don't hit (gap): 16-3/8 inch - 1/16 inch = 16-5/16 inch width
  4. Final measurements for each door (order two) = 16-5/16 width x 25-3/4 inch height (remember to deduct the 1/4-inch from height)

Please remember we have provided an example. Check your measurements twice to be certain you got it right.

Calculating for a Lazy Susan

The Lazy Susan creates a butt joint where the doors meet at a 90-degree angle. Therefore, one door needs to be longer than the other. Use these tips to get the measurement right:

Door overlays only happen on one side of the setup

One door much is shorter than the other. The longer door will lie on top to make the 90-degree angle.

The Formula
Left Side = width + 1/2-inch (overlay) x height + 1-inch  (overlay)
Right Side = (width + 1/2-inch) - thickness of door x height + 1-inch (overlay)

The Example
Get an opening measurement for the Lazy Susan:
Left side = 14 inch width x 30-inch height
Right side = 14-inch width x 30-inch height
Door thickness = 3/4-inch

Calculate the left side door:
Width = 14-inch + 1/2-inch overlay = 14-1/2 inch width
Height = 28-inch + 1-inch = 29-inch

Measure the right side door:
Width = 14-inch + 1/2-inch overlay - 3/4 inch (door thickness) = 12-3/4 inch width
Height = 28-inch + 1-inch = 29-inch

Additionally, you need to use the “reference name” to say that the larger door should use a large stile.


Keep track of your measurements, check your measurements twice when they are entered in the order form. Only you can take the proper measurements. If there are enough errors, you should check your math again. When the process is done, you will have amazing cabinet doors that fit perfectly.

This guide is used as examples.  We cannot take responsibility for any errors in measurements based on these recommendations.  Ensure your measurements are correct before submitting an order.
