Cabinet Door Measuring Guide

Below are some basic guidelines for measuring for your cabinet doors. Your measuring needs maybe different than the examples below. Before submitting your order, make sure you are 100% confident in your measurements. We do not take responsibility for any errors based on our recommendations. We want to make sure you get the correct size cabinets for your project. With a few basic tools and some careful measurements, you’ll be ready to place your order and create the kitchen of your dreams.

Accurate measurements are crucial to receiving the correct sized doors you need for your project. Precision is key, as your cabinet doors will be custom made to your specifications and incorrect measurements lead to ill-fitting, non-returnable cabinet doors. Double-check your work until you are confident that you are ordering the perfect size cabinet doors for your project. To ensure your measurements reflect your needs please follow these simple steps.

Required Tools
• Note Pad
• Pencil
• Tape Measure

Measuring Tips
• We recommend that you measure each opening at least twice to prevent mistakes
• Write down each measurement on your note pad
• Measure all door openings to the nearest 1/16"
• Be sure to notate your measurements as width x height. For example, you may write down something such as width 14" x 30" height
• If you have existing cabinet doors, it’s best to remove them before measuring

*These instructions are helpful if you are installing popular concealed hinge cabinet doors. If you choose a different type of hinge, your measuring instructions may differ. Please note that we do not accept responsibility for any errors in measurements based on these recommendations.

 


 

STEP ONE: Measuring Your Cabinets
With your tape measure you want to measure on the inside of the frame. Measure from inside edge to inside edge and then notate that number, this will be your rough opening measurement. Do this for both the width and height for each door. Write down your measurement width x height for each inside frame measure.

STEP TWO: Calculating Door Size
Now that you have all of your measurements, it’s time to calculate the exact cabinet door size you'll need. These calculations will be what you input into your online order form. The calculations vary slightly depending on your door style. This guide includes instructions for measuring:

Door Overlays
Split Doors
Inset Doors
Split Inset Doors
Lazy Susans

 

Door Overlays
The measurements you have reflect the inside edges of your cabinets. If you want to have your doors extend past the cabinet openings you need to add in a door overlay to your calculation. The majority of doors allow for a 1/2” overlay. For a 1/2” overlay you will to add 1” to both the width and height of each measurement that you have written down.
FORMULA
(width + 2overlay) + (height +2overlay) = Measurement

EXAMPLE
For an opening measurement of 14” x 30”, add 1 inch to both measurements so it now reads 15” x 31”.

*In our example we use a 1/2” overlay. Your door specifications may differ, so take your needs into account when calculating your overlay.
*These measurements are guidelines. Ensure your measurements match the specifications of your exact hinges type.

 

Split Door Measurement
If you have a cabinet section that needs a split door (2 doors per cabinet opening) the calculation will be slightly different. If you are unsure whether you should order split doors, we recommend that you order two doors for any opening greater than 22" wide. For split doors with a 1/2” overlay add 1 inch to both the width and height. Then additionally for the width divide the entire number by 2 and subtract 1/16”. This allows for the two doors with a 1/8" gap between the cabinet doors.
FORMULA
Split door with 1/2” overlay = (width + 1)/2 – 1/16 x height + 1

EXAMPLE
For an opening measurement of 30” x 28”
Calculate the width:
Add 1 inch for the overlay: 30" + 1” = 31"
Divide by 2 for the doors: 31"/2 = 15 1/2"
Subtract 1/16 for the gap: 15 1/2" - 1/16" = 15 7/16"
Final measurements = 15 7/16” x 29

*These measurements are guidelines. Ensure your measurements match the specifications of your exact hinges type.

 

Inset Cabinet Doors
To properly measure for an inset cabinet door (doors that fit inside the cabinet frame), measure the opening as instructed above and then subtract 1/8" from both the width and height of the frame to make sure the doors have the proper gap.
FORMULA
Inset cabinet doors = width – 1/4” x height – 1/4”

EXAMPLE
For an opening measurement of 14" x 30"
Inset calculation: 14" - 1/4" x 30” - 1/4" = 13 3/4" x 29 3/4"

 

Split Inset Cabinet Doors
Follow the same steps as above. For the width then divide by 2 (since there are 2 doors) and then subtract 1/16"
FORMULA
Inset cabinet split doors = (width – 1/4”)/2 – 1/16 x height – 1/4”>

EXAMPLE
For an opening measurement of 29” x 30”
Calculate the width:
Inset measurement: 29" - 1/4" = 28 3/4"
Divide by 2 for the doors: 28 3/4" /2 = 14 3/8"
Subtract 1/16 for the gap: 14 3/8" - 1/16"
Final width measurement: 14 5/16"

*These measurements are guidelines. Ensure your measurements match the specifications of your exact hinges type.

 

Measuring For Lazy Susans

Lazy Susans include the measurements for two doors that create a Butt Joint. A Butt Joint style allows for the doors to create a 90 degree angle by having one of the doors on top of the other when they intersect. To do this one door’s width needs to be slightly longer than the other. Take the rough opening measurements for both sides like you would for any other door. With a Lazy Susan keep in mind the following items:

• Door overlays will only be on one side when measuring the width
• One door’s width (either left or right) needs to be shorter than the other to lay on top of the other door in order to make the 90 degree angle. The shortness in width equals the thickness of the door.
FORMULA
Left Side = width + 1/2" x height + 1"
Right Side = (width + 1/2") - thickness of door x height + 1"

EXAMPLE
Start with your opening measurement of your Lazy Susan:
Left side = 12 1/2” wide x 28" tall
Right side = 12 1/2” wide x 28" tall
Door thickness = 3/4”
Left side door measurement:
Width = 12 1/2” + 1/2” = 13"
Height = 28" + 1" = 29"
Right side door measurement:
Width = 12 1/2” + 1/2” – 3/4” (door thickness) = 12 1/4”
Height = 28" + 1" = 29"

*For the wider door in the "additional instructions" box on the order form notate: "Please make the 13" x 29" door with large stile for Lazy Susan."

Additional Tips

Keep careful record of your calculations on your notepad and be sure to double check—or triple check—your work. Make sure you notate all final sizes. Carefully mark down your final custom cabinet door sizes as well as how many of each type you want to order.

Input your final custom door sizes and quantities into our Order Form. Proofread it to make sure you entered every detail error-free. When you feel confident, click submit. You're now well on your way to owning your perfect cabinets.

Ensure your measurements are correct before submitting your order, as changes to your order cannot be made after it is submitted. This is a measuring guide that uses sample measurement. We do not take responsibility for any errors in measurements based on these recommendations.
