| Quick Answer: A standard door frame in the United States is 80 inches tall (6 feet 8 inches) and 32–36 inches wide, with a depth matching your wall thickness (typically 4-9/16 inches for a 2x4 wall). Seven-foot (84-inch) frames are common in new construction. Eight-foot frames exist but require special ordering. Six-foot frames are non-standard and rarely installed in residential builds after roughly the mid-20th century. |

Here's the thing: we get this question constantly. Not because people are confused about doors generally, but because they're standing in front of a rough opening with a tape measure, trying to figure out whether a standard frame will fit or whether they need something custom. We've been building since 2012 out of our Ogden, Utah facility, and across 200,000+ households, the number-one installation mistake we see isn't the door itself. It's a mismatch between the door frame and the rough opening.
So let's get the numbers straight. Then, if you're thinking about a hidden bookcase door or a hidden pantry door in that opening, I'll tell you exactly what changes, and what doesn't, when you go from a standard door frame to one of ours.
Is a door frame 6 feet tall?
Are door frames 6 feet tall?
No. Six feet is 72 inches, and a standard residential door frame is 80 inches, that's 6 feet 8 inches. The 6-foot figure is a common misremembering, probably because people round down. A true 72-inch door frame does exist in older homes (pre-1950s construction especially), but if you walk into a hardware store and ask for a "standard" frame today, you're getting 80 inches.
How tall is a normal door frame?
The normal interior door frame height in the U.S. is 80 inches (6'8"). That's what you'll find on virtually every pre-hung interior door at every lumber yard and big-box store in the country. Exterior door frames run the same height, though many builders now default to 84 inches (7 feet) on exterior openings, particularly in newer builds.
What is the length of a normal door frame?
"Length" here usually means height: 80 inches is the standard. Width is a separate measurement. Standard interior door widths run 24, 28, 30, 32, and 36 inches. The most common single-door rough opening is 34 inches wide by 82 inches tall, that extra 2 inches of height accounts for the frame, threshold, and shimming room.
What is considered a door frame?
The door frame is the assembly of lumber (or steel, in commercial applications) that lines a rough opening in the wall. Three main parts: two vertical pieces called jambs, a horizontal piece at the top called the head jamb, and the threshold or sill at the bottom on exterior doors. The casing, the trim you see from the room side, is decorative, not structural. The frame is what the door hinges into and latches against. Depth matters too: a standard frame for a 2x4 wall is 4-9/16 inches deep. Thicker walls (2x6 construction, or walls with extra insulation) need a deeper jamb. We sell door jamb depth options precisely because this spec varies more than people expect.
Are doors 7 feet tall?
Are 7-foot doors common?
Increasingly, yes. Seven-foot (84-inch) doors have become the baseline in a lot of new residential construction over the past two decades, particularly in the western U.S. and in higher-end builds. Ceiling heights have crept up, 9-foot and 10-foot ceilings are standard in many new homes, and a 6'8" door can look stubby against a 9-foot ceiling. So builders started defaulting to 84-inch doors. You'll find 7-foot pre-hung units at most large lumber yards now, though selection is narrower than at 80 inches.
How tall is a 7-foot door?
Exactly 84 inches. The rough opening for a 7-foot door is typically 86 inches tall to allow for the frame, the threshold gap, and shimming. If you're measuring an existing opening to see whether it can take a 7-foot door, you need at least 85-1/2 inches of clear rough opening height. Check that before you order anything.
How many feet tall are most doors?
Most installed interior doors in existing U.S. housing stock are 6 feet 8 inches (80 inches). Most doors going into new residential construction today are either 6'8" or 7 feet, depending on the builder's standard. In commercial construction, 7 feet is common; 8 feet is not unusual in lobbies and corridors.
Can a door be 8 feet tall?
Yes. Eight-foot (96-inch) doors are standard in many commercial buildings and appear in luxury residential projects with 10-foot or higher ceilings. They're not a special order for commercial suppliers, but for residential you're typically looking at custom or semi-custom fabrication. The rough opening for a 96-inch door needs to be about 98 inches tall. If your home has 9-foot ceilings and you're building out a media room or home office with a hidden door, an 8-foot opening is absolutely workable, we build to custom heights regularly. See our custom height options if your opening falls outside standard dimensions.
How many feet is a door frame?
How many feet are in a door frame?
A standard door frame is 6 feet 8 inches tall (80 inches), 32–36 inches wide, and 4-9/16 inches deep for a standard 2x4 wall. Those three dimensions, height, width, depth, are what you need before you order any door or frame. Miss one of them and you'll get burned on at least one of the others.
How big is a standard door frame in feet?
Here's a quick reference table for the most common standard sizes:
| Opening Type | Frame Height | Frame Width | Typical Rough Opening |
|---|---|---|---|
| Standard interior | 80 in (6'8") | 32–36 in | Width + 2 in / Height + 2 in |
| 7-foot interior/exterior | 84 in (7'0") | 32–36 in | Width + 2 in / 86 in |
| 8-foot commercial/luxury | 96 in (8'0") | 36–48 in | Width + 2 in / 98 in |
| Older/historic homes | 72–78 in | 28–32 in | Varies, always measure |
What is the normal size of a door frame?
Normal is 80 inches tall by 32–36 inches wide by 4-9/16 inches deep. That's the frame. The door slab itself is slightly smaller, about 1/8-inch clearance on each side and at the top so it swings without binding. The rough opening in the wall framing is larger still, to leave room for the frame plus shimming. Always measure the rough opening, not just the door or the casing. Our measurement charts page walks through exactly how to take each dimension correctly.
Is every door 6 feet tall?
Are all doors 6 feet tall?
No. Standard doors are 6 feet 8 inches, not 6 feet flat. And not all doors hit that standard. Older homes, basement doors, closet doors, and utility spaces often have shorter openings. Some original craftsman-era homes have 7-foot doors. Historic brownstones can have 8-foot or even 9-foot interior doors. Measure every opening individually. Don't assume.
Do they make 6-foot doors?
They do, but you typically won't find them at a standard lumber yard. A true 72-inch (6-foot) door is a special order. You encounter them mainly in older homes built with lower ceilings, or occasionally in basement utility access situations. If you have a 72-inch opening, your realistic options are: custom-order a 72-inch door, frame the opening up to 80 inches if the structure allows, or use a different door type (bifold, barn-style sliding) that's less dependent on a standard frame height.
Is a door 7 feet tall?
Some are, and that number is growing. Seven-foot doors are now standard in a lot of new residential builds. If you're in a home built in the last 10–15 years with 9-foot ceilings, there's a reasonable chance your interior doors are already 84 inches. The only way to know for certain is to measure the door slab itself (not the casing) or the rough opening.
How does door frame height affect a hidden bookcase door?
I'll tell you what surprised us in the early years at Murphy Door®. We assumed homeowners knew their rough opening dimensions before calling us. They almost never did. They knew what they wanted the door to look like, a floor-to-ceiling bookcase, a pantry hidden behind a wall of shelves, but they hadn't confirmed whether the rough opening was 80 inches or 84 inches or something in between.
Here's why it matters for a hidden door specifically. A hidden flush-mount bookcase door needs to be sized to fill the entire visible wall panel, not just the opening. If the door is 80 inches and the ceiling is 96 inches, you've got 16 inches of wall above the door that breaks the illusion. That gap tells everyone there's a door there. The door needs to read as a built-in bookcase, which means it needs to run floor-to-ceiling or be paired with a header treatment that makes the transition invisible.
We handle this a few ways. Standard heights ship in 80-inch and 84-inch configurations. For anything else, we do custom heights, our custom height option covers openings outside the standard range. For the reveal, that 3/16-inch gap around the door that's critical for both function and concealment, we ship shim stock pre-cut with a written torque spec for the hinge bolts, so your contractor isn't guessing. Our door installation shims are part of every order for exactly this reason.
The hidden bookcase door starting at $1,440 fits a standard 80-inch opening. If you're working with a 7-foot opening, that's a different configuration, call us at 888-458-5911 and we'll spec it out. The single flush-mount oak hidden bookcase door and the walnut version are both configurable to your opening dimensions. Same for the paint-grade hidden pantry door if you're doing a kitchen or utility concealment.
What door frame depth do I actually need?
This is the dimension that catches people off guard. Height and width are obvious. Depth, the jamb depth, is easy to miss until you've already ordered the door.
Standard 2x4 wall construction gives you a nominal 3-1/2-inch stud with drywall on both sides, landing at about 4-9/16 inches of total wall thickness. That's the standard jamb depth. But a lot of homes have:
- 2x6 exterior walls (about 6-9/16 inches deep)
- Extra insulation or furring added during renovation (adds 1–2 inches)
- Brick veneer or stone cladding on exterior walls
- Historic plaster walls thicker than modern drywall
If your jamb depth doesn't match your wall thickness, the casing won't sit flush. On a standard door that's an aesthetic problem. On a hidden door it's a functional problem, the door won't conceal properly if the frame is proud of or recessed into the wall surface. We offer a deep jamb depth option for thicker walls, and a jamb extension for inswing applications. Measure your wall thickness before you order anything.
Can I put a hidden door in a non-standard frame height?
Yes, and we do it regularly. Here's where I'll be direct: non-standard heights are not a dealbreaker, but they require a conversation before you order. A 78-inch opening in an older home is common. A 90-inch opening in a newer build with 10-foot ceilings is less common but absolutely workable. An 82-inch opening, where someone previously modified the framing, is the most complicated, because it's neither the standard 80 nor the standard 84.
The process is straightforward. You give us the rough opening dimensions: height, width, depth. We build to those dimensions. Every Murphy Door® hidden door is built on Vaultwood Core (a proprietary MDF engineered stronger than standard MDF) with real wood veneer, solid hardwood face frames, and solid-wood components. That construction method is what lets us hit custom dimensions without the warp and twist you'd get from a solid-slab door. Vaultwood Core stays dimensionally stable across humidity cycles, which matters especially for a door that needs to maintain a 3/16-inch reveal year-round.
If you want to see how the full process works, from measurement to installation, our process page walks through it step by step. Want to talk through your specific opening before you order? Call 888-458-5911. We've figured out most of the unusual configurations already. We've been at this long enough to know which corners to cut and which corners to weld.
What about casing and trim around a door frame?
The casing is what makes a door frame look finished. On a standard door, casing is an afterthought, you pick a profile at the lumber yard and nail it on. On a hidden door, casing is part of the concealment strategy. The wrong casing profile breaks the illusion by signaling "there's a door here." The right casing reads as architectural trim that belongs on any wall.
We build our own casing profiles to match the door construction. The front door casing and rear door casing are designed to align with the face frame of the bookcase door so the transition from wall to door is as tight as possible. If you've got a specific architectural style, fluted pilasters, crown molding headers, arch treatments, we have options for those too. The casing and trim collection covers the full range. The arch add-on for the face frame is worth looking at if you're doing a library or study application where the archway treatment adds the right visual weight.

Frequently Asked Questions
Q: What is the standard height of a door frame?
A: The standard door frame height in the U.S. is 80 inches, or 6 feet 8 inches. Seven-foot (84-inch) frames are increasingly common in new construction, particularly in homes with 9-foot or higher ceilings. Eight-foot frames exist in commercial and luxury residential builds. Anything outside those three sizes is typically a custom or non-standard configuration.
Q: What is the length of a normal door frame?
A: "Length" in door terminology usually refers to height: 80 inches is normal for residential. Width is separate, standard interior widths run 24, 28, 30, 32, and 36 inches, with 32 and 36 being most common. Depth (jamb depth) is 4-9/16 inches for a standard 2x4 wall. You need all three measurements before ordering any door or frame.
Q: How many feet are in a door frame?
A: A standard door frame is 6 feet 8 inches tall (80 inches), 2.5–3 feet wide, and about 4-9/16 inches deep for standard wall construction. The rough opening in the wall framing is about 2 inches taller and 2 inches wider than the frame to allow for shimming and leveling.
Q: Do they make 6-foot doors?
A: Yes, but they're a special order, not a stock item. True 72-inch (6-foot) doors show up mainly in older homes built before modern height standards took hold, or in utility and basement applications. If you have a 72-inch rough opening, you can custom-order a door to fit, frame the opening up to 80 inches if the structure allows, or consider a sliding or bifold configuration that's less constrained by frame height.
Q: What is considered a door frame?
A: A door frame is the structural assembly of lumber or steel that lines a rough opening in the wall. It consists of two vertical jambs, a horizontal head jamb at the top, and a threshold or sill at the bottom on exterior doors. The decorative casing you see from the room side is trim, not structural. The frame is what the door hinges into, latches against, and what gets shimmed plumb and square during installation.
Q: Can a door be 8 feet tall?
A: Yes. Eight-foot (96-inch) doors are standard in commercial construction and appear in residential builds with 10-foot or higher ceilings. The rough opening needs to be about 98 inches tall to accommodate the frame. For a hidden door application at 8 feet, the floor-to-ceiling bookcase effect works especially well, the full-height panel reads naturally against a tall wall. Murphy Door® builds to custom heights. Call 888-458-5911 to spec an 8-foot opening.
