How Much Should Doors Be Undercut?
12 Apr 2021
Doors separate different elements of your home and are great for privacy safety and security. But a door couldn’t function without gaps around it because it needs to open and close.
When you’re installing a door, you’d probably like to know if there’s a standard size gap you should have between your door and the floor. That way it can open freely and swing back and forth.
Undercut v floor clearance
An undercut is the distance between the bottom of the door and the door frame itself. Any carpenter generally uses this term. Many people think the undercut and floor clearance are the same, but that’s not technically correct.
Floor clearance is the distance between the bottom of the door and the material directly below the door, for example any wood flooring, vinyl, carpet or tiles.
Internal door undercuts
We hang doors, day in day out at Door Stop. As a guide the average undercut of your door should be between 8mm and 10mm, that’s around ⅝ inch to ¾ inch from the bottom of the frame.
But there are exceptions. If you have a deep shagpile carpet that is thick, greater clearance is required. On these occasions it’s best to shave off the door. It’s never an easy task determining how much you should take off, so
if you are in doubt, shave or cut off a little and if it’s not enough, shave off some more. Remember less is better or you may damage the door’s structural integrity.
