The gap between a door and frame should be ⅛-inch on the sides and at the top, applicable to both interior and exterior doors. The bottom of an interior door should have a space of at least ½” to ¾” between the floor. An exterior door should not have hardly any gap at the bottom. When installing an interior door, leave a ⅛-inch space between the door and frame on each side and a ⅛-inch reveal (the gap at the top of the door). The floor clearance for an interior door can vary between 1/2-inch and 3/4-inch, depending on the height of your flooring.
To fix a gap between a door and its frame, you can install a door sweep to reduce drafts from the bottom and top of your door or seal the gaps with a door wedge. While internal doors come with a few centimetres of lipping to trim doors to size, it is essential to avoid wasting time, effort, and timber on a door that’s the wrong size for your frame.
To ensure a snug fit and peace of mind, follow these steps:
Diagnose the problem. To provide good thermal and sound insulation for internal doors, there should be a gap of around 2-3mm between the door leaf and frame at the top and sides with a gap of around 9mm at the bottom. A gap of around 1/8th of an inch is recommended for standard doors to keep the elements out, protect the paint on the trim, and ensure that the door closes and closes properly.
Measure the gap between the door and the floor. The gap between the door and the floor should be between a half-inch and three-quarters of an inch for optimal functionality. In most cases, gaps of interior doors on top and on each side are equal to 3mm, and hinges at the bottom should not be less than 2 cm.
In summary, ensuring a ⅛-inch gap between a door and frame is crucial for optimal functionality and safety.

What is the standard interior door gap?
The gap between the door and the floor is crucial for optimal functionality. Following the installation guide ensures smooth operation, effective air circulation, and proper clearance to prevent flooring damage. Interior doors, such as bathroom, bedroom, and closet doors, can be premade or painted over. However, exterior paint should not be used on interior doors as it releases harmful chemicals and may not be suitable for most homes due to inadequate ventilation. Premade doors can be painted over, but it is not recommended for DIY projects.
What is the code for the gap under a door?
NFPA 80 has established a maximum gap between doors and frames on the sides, top, and bottom, with a range of permissible distances from an eighth to three-quarters of an inch, depending on the side.
How to fix a gap between an interior door and frame?
To install a shim, open the door and place a support or wedge under it to relieve tension. Remove the hinge screws and insert the shim between the hinge leaf and the door. Reattach the hinge leaf with screws. Inspect the opening for general condition and ensure the frame opening width is consistent from top to bottom. If the gap is not consistent, it may be due to incorrect frame installation, causing severe door and hardware problems. This manual does not address improper frame installation.
Can see light around an interior door?
If light or drafts are coming around your door since it was installed, it’s likely not level in the frame. This issue can be noticed immediately or when you move into a new home. The main cause of drafts and light coming around the door is if a contractor did not properly install weather stripping around the frame, which ensures the frame is sealed and creates a flush opening for the door.
How much gap should be around an interior door?
Trim the door to size and ensure a 2mm gap on either side and at the top. The gap at the bottom depends on the thickness of the flooring/carpet. Plane the door using an electric plane or sand for a smooth finish. If the existing frames aren’t square, buy a doorset with the door already hung in its frame to reduce problems and time.
Check if the new hinges fit the old ones in the frame. If not, mark the location and remove extra wood. Screw each hinge in place with one center screw, sticking the hinge knuckle out from the frame edge. Prop the door in the frame using wedges to ensure the correct gap at the bottom. Note that moulded, real wood veneer, foil, hardboard, and MDF hollowcore doors should have 2 hinges, while feature and primed doors should have 3 hinges.
How much clearance is needed between door and frame?
For standard doors, a gap of 1/8th of an inch is recommended to keep elements out, protect trim paint, and ensure smooth door closing and opening. The gap should be equal to the door’s thickness, with a little extra room for clearance. For thicker doors, more space is needed for movement during opening and closing. Measurements should be made from hinge side edge to latch side edge. Smaller doors like pocket doors or cabinet doors should have a smaller gap to avoid drag during opening and closing.
The most common type of door is the interior door, which can be made from various materials or a simple slab door. The gap should be tight enough to prevent visible light from coming through but not so tight that the door doesn’t open and close properly.
How much reveal between door and frame?
The reveal is the gap between the door jamb and trim. To ensure precision, a combination square can be used to mark a consistent 1/8 to 1/4 inch area around the door frame. These marks serve as a guide for the precise positioning of the trim. It is important to take great care when measuring the reveal in order to achieve a balanced and symmetrical appearance. Prior to installing the trim, it is essential to ensure that the jamb and wall are perfectly aligned and flush with one another.
What is the maximum gap between a door and a frame?
In order to correctly install a door, it is essential to ensure that a gap of 2mm or 3mm is maintained between the door and the frame on all sides and at the top. Should it be necessary, all four sides should be cut equally in order to maintain the desired shape. In the event of minor alterations being required, it is recommended that a plane be used to trim the wood, commencing at the periphery of the door and progressing towards the centre of the door’s thickness. In the event that larger adjustments are required, it is recommended that a panel or circular saw be utilised.

What is the minimum space between door frame and wall?
In order to create a door rough-out, it is essential to ensure that a minimum distance of 3 inches is maintained from the corner to the door on rough-framed walls. This distance must be accounted for in order to accommodate the drywall. Additionally, a minimum of 4 inches of space should be allotted for perpendicular walls in order to accommodate the door jamb, stud, and jack.
How much space should I leave for a door frame?
To properly frame a door rough opening, add 2 inches to the width and 2-1/2 inches to the height of the door. This allows room for the door frame to be spaced off the sub-floor and allows for perfect plumbing, leveling, and squareness. The rough opening should be larger than the door and frame for three reasons: 1) to allow for adjustment of the door and frame, 2) to account for variations in door sizes by manufacturer, 3) and to allow for expansion and contraction of the wall as it gets bigger and smaller as the seasons change, which is caused by moisture absorption and shrinkage. By ensuring proper framing, you can ensure a smooth and functional door installation.
📹 Wall Sticks Out Past Door Jamb / Frame? Simple Way To Fix Door Jamb Gap!
Does your wall stick out past your door jam, leaving a gap? If you’ve recently changed out your drywall, like I did or if you replaced …
#1 looks good. but on the big gap on left I’d be concerned about it cracking with age. I’ve only used this for small holes – can you really do long, thick sections and expect it to last? I have a door thats going to need at least 3/8 ” all around. On a previous door i cut a strip of wood to fill the gap and it came out great, but was a pain.
I hired some guys to hang doors in my house. They used the caulking method and now here I am looking up articles to redo all the work they did – suffice to say it looks cheap AF. I might try the wood filler, I’ve used it before for other projects, but I can’t help but wonder if I shouldn’t try to trim down the door frame. I know it’s more work but damn this caulking looks horrible.
Good article, Steven. I agree that when you have a consistent offset around the frame it makes sense to add the jamb extension. But I also agree with a couple other commenters below that it generally looks better to add a secondary “step” between the existing door jamb and the extension strip. This way, if you get future movement or have any trouble getting PERFECT flushness of the extension strip to the jamb, it won’t show due to the step. If possible this step should be a minimum of 1/8″ but better if more like 1/4″, similar to other steps in trims and moldings. In other words, make a deliberate step as opposed to having a very slight step that looks like a mistake or misalignment. This would not be possible if you are doing a low budget reno and reusing old casings, but if you are cutting new, make the casings enough longer to allow for a deliberate “step”. Obviously, this detail is subjective, I’m just sharing my opinion as an architect and occasional finish carpenter. Keep up the good work in helping people solve problems!
Problem with older houses is you’ll have doors where, for example, the jamb is proud at at the top and then drywall is proud at the bottom; meaning the gap isn’t consistent for a strip of wood to fill it evenly. People plane the jamb, cut out drywall, or just caulk their problems away. A pain nevertheless. This solution only works where its a simple uniform gap throughout. If your jamb extension is only for half the length of the door, it would also look pretty bad
Also the ONLY solution to use for this issue if you have STAINED WOOD trim. Like I do. In my entire house. All of it. Not a single inch of painted wood to be found. The filler strip, or infill, can be stained and varnished very quickly. In my house, I’m resigned to having to do a double reveal, as well. You simply cannot caulk stained wood.
I’m not able to do this because I need a stain finish, but rather than trying to cut into the drywall I’m thinking about shaving off some of the casing instead. The benefit is that I can set it up on a table saw and cut the step into the back of the casing without all the mess and hassle of cutting drywall. But will it work? I don’t know. I might not risk it on wedge-shaped casing like that but mine’s rectangular and I can just use thicker wood.
If the wall has a bow, and the gap isn’t consistent, should I install a thick extension that protrudes (using glue) and then plane it down? Is a power planer the best tool, or is there something better that would allow me to basically follow the drywall surface? I have a 1/2″ recess on my brand new front door because the wall actually leans that much. With an interior door I just installed myself, the stud has a kink, so I have 1/4″ recess on one side at the bottom and 1/4″ recess on the other side at the top.
This is exactly what I need to do for a new exterior door I installed at my parents house. Unfortunately while installing the door and maintaining plumb, I was not able to keep the door frame even with the drywall inside. I wanted to confirm my thoughts on ripping and extending the door frame. Thanks and great article!
Thats called screen mould and it’s – these days – used for butt joints in ply on soffits n similar. This application of it is great but flushing it with the jamb face creates a joint that doesn’t finish well. The back side of that screen mould has a sharp corner but the corner of the jamb does not. Trying to flush those two doesnt finish well at all. It’s a much better look to back it away from the corner of the jamb 1/8 or 3/16 as you would your casing then back the casing up from the screen mould edge thereby creating a double reveal. It’s a way better look that doesn’t scream DIY.
