OVERVIEW EXAMPLE:

CABINET OPENING= 10" WIDE X 20" TALL
CABINET DOOR= 9 13/16" WIDE AND 19 13/16" TALL

SINGLE DOOR ON A SINGLE FRAME OPENING:

Measuring cabinet doors from the single cabinet opening brings about a few obvious scenarios. One, you have either lost or the existing doors have been removed and are no longer available. Two, you are tired of the existing cabinet doors and wish to apply new doors to your existing cabinet boxes. And three, most likely you are changing or updating the hinge type to something other than the existing hinge used on the old cabinet doors.

For this example we will be using a Flush construction hinge and hinge plate. There are a few different combinations of hinges and hinge plates that will result in the same "flush" construction but the doors are always ordered using the same formula.

Lets say your opening is 10” wide and 20” tall. If I wanted to put 1 door on this opening I would take 10” and subtract 3/32" from the left side and 3/32" from the right side. This gets me a 9 13/16” cabinet door width. You would do the same with the height as well. Take the 20” height and subtract 3/32” from the bottom, and 3/32” from the top. This gets us a 19 13/16” tall cabinet door. Thus, you will need to order a door with a width of 9 13/16” wide by 19 13/16” tall for this single opening.

This is a two piece hinge system (hinge and hinge plate). Attach your plate to the face frame and attach the hinge to the cabinet door. Then clip the two pieces together to attach the cabinet door to the cabinet box.

PAIR OF DOORS ON A SINGLE FRAME OPENING:

If you have an opening with a pair of doors to be installed, it is actually very easy to calculate. Say you have an opening of 20” wide by 30” tall. To calculate the width of each door you would take 20” and divide by 2 (two doors). This gets us 10”. Then simply subtract 3/32” from the width to which gets us 9 29/32”. The width of each cabinet door you need to order will be 9 29/32” wide. The height of the cabinet door is calculated the same as it would be on a single door opening. Take the opening height of 30” and simply subtract 3/32" from the top and another 3/32” from the bottom to get 29 13/16” for the cabinet door height. To clarify, for this opening, you will need to order 2 doors at 9 29/32” wide by 29 13/16” tall.

DO NOT FORGET TO ORDER THE HINGE AND THE HINGE PLATE.
