- A properly measured door will have a small space of about 1/4" between the outside of the door's jambs and the wall framing (rough opening). A door is not meant to fit snugly in any opening, if your door fits snugly it was either measured incorrectly or your rough opening is out of square; some adjustments to your opening maybe necessary
- The door size is determined by subtracting 2" off the width and height of the rough opening, this is typical of a conventional door as well as all of our products
FAQ: What do I do if I have an oddly sized door that you do not have a size for? Example, my rough opening is 38-1/2" what do I order?
Answer: While we can custom build any size that you need, it is less expensive to fill in the opening a bit to make a standard size work. So, if you have a 1/2" thick board you can attach it to one side or the other in your rough opening to bring the RO size down to 38" for a 36" door. Keep in mind that however you fill your RO with, you do not want to go below your target with, in this example that is 38" a fraction larger is fine but do not modify it so that it is less than 38".
Another example, lets say your opening is around 38-3/4" and you want to close the distance by 3/4" Filling a full 3/4 of an inch on one side only might present an issue with the case molding on your door covering your opening properly. In this case, we suggest installing 3/8" material on both sides of your rough opening.
